A work of fiction, meant for adults.  Read something else if you are not an adult, or are offended 
by stories with sexual content.  Then again, if all youre looking for is in-out, in-out, in-out, you 
should probably read something else.  I welcome constructive comments.  Enjoy.

	This is a romance about Emily and I.  Its got microprocessors, lust, economics, 
commuting, and sex.  If this isnt what youre looking for in a story, fuck off and read something 
else.  Even better, write something yourself.

	Id gotten an email on the account I use for posting to usenet groups.  One of the things I 
do on the side is build gadgets using single chip microprocessors called PICs.  I watch a number 
of usenet groups dealing with the things, and often post what I hope are answers to questions 
people have, building gadgets when I feel like it.

	This request was for a fairly simple and specific motor-control gadget.  Press a button and 
hold it, the motor turns on.  Release the button and the motor turns off.  The trick is the gadget 
learns the on and off times and repeats them until the button is pushed again, and it trains to 
new times.  Sounded pretty easy; Id never built one before.

	We traded emails; I needed more detail.  What kind of motor?  How big?  What were the 
ranges of on and off times?  Does it need to run on batteries, self contained, or can it be built into 
a larger enclosure?  Do you want automatic shutoff after a preset time?  Do you want indicator 
lights or beeps?

	I learned quickly that my client was a high level software type, with no hardware 
background.  When I asked if it was an AC or DC motor, they didnt know.  Okay, does it run on 
batteries?  Yes.  How many of what size?  Two small ones.  Make that a negative hardware 
background, but were making progress.

	I was getting frustrated and needed more information -- email was just too slow.  I sent 
out my work phone number and told them to give me a call so we could talk details.  I had the 
code pretty much worked out, using a small PIC to control a blue LED in time to a pushbutton.  
The critical hardware part was going to be motor control; I needed specifics on the motor.

	A few mornings later I got a phone call.  I answered and a female voice asked for my email 
name.  Yup thats me, I said.  I gave her my first name; shed get that if she left me voicemail.  
Her name was Emily.  We chatted for a few minutes.  She thought she recognized the phone 
number and asked where I worked; I told her.  She told me where she worked, another high-tech 
company a few miles away.

	I dont remember who suggested it, but we agreed to get together to talk at her office.  I 
looked at the schedule on my wall and told her I could be there a little after four, and would need 
to leave shortly after five.  No problem, she told me, thats when she needed to leave as well.

	She gave me her extension and told me to giver her a ring when I got to the lobby.  Then I 
told her Id be wearing a black leather jacket, white shirt, and a black tie with red chili peppers on 
it.  Really? she squeaked over the phone.  I laughed; she really did squeak.  I told her it was a 
hard tie to miss.  She started laughing and said shed see me later that day.  Was there something 
familiar about that laugh?  I was looking forward to meeting her; Id spent too long focused only 
on work.  Jennifer was gone; it was long past time for me to move on.

	Now for economics -- I work in the Silicon Valley; its a great place to work.  Its also a 
rotten place to live; housing prices are astronomical.  So I live in whats called the East Bay and 
commute on the bus.  It works out well; company employees get free bus passes.  The bus stop 
is a couple of blocks from my house, and I get dropped off right in front of the office.  The bus is 
comfortable; the seats recline, and it beats the hell out of driving at least an hour and a half twice a 
day in ugly traffic.  Its also a great way to get out of late afternoon meetings.  Got to go, cant 
miss my bus!

	I took an earlier bus that afternoon and got off at Emilys place.  Her company is also 
part of the commute program; they have a very nice bus stop right in front of their main building.  
I went in and gave her a call from the lobby; she laughed when I said hello and said shed be right 
down.

	A few minutes later as I was standing around in the lobby I heard her call my name.  I 
turned around and realized why shed squeaked when I told her what I was wearing, and why 
shed been laughing.  When I saw her I started laughing as well; wed ridden that damn bus 
together most days of the week for the last two years.  We hugged and we went to a small 
conference room off the lobby.

	That Emily, the one from the bus; shes about my height, long black hair, good waist, and 
strong slender legs.  Her Hindu heritage blessed her with clear dark almond skin, beautiful oval 
eyes, and a pair of firm, full breasts that make my mind go blank.  She has a wonderful laugh, and 
the kind of laid-back personality required to survive the commute.

	I couldnt believe it was you, she said when we sat down, still laughing a bit.

	I shook my head.  We sat together sometimes; I wouldnt mind sitting next to her more 
often.  Neither of us were real conversationalists on the bus, we tended to read or sleep.  We 
swapped books and magazines all the time, even working out an informal trade; I brought along 
The Economist and she brought New Scientist.  We chatted for a few minutes, then I looked at 
my watch.

We could take the express bus and talk on the way, wed be more likely to get seats.

	She nodded.  I thought so too.  My bag is ready to go.

	So, I need more details about the motor you want to run.

	She lowered her head and blushed a little.  I didnt know what to do with that.  Can you 
get me one to work with?  I only need the motor, not the rest of whatever it is.  Maybe that 
would be easier to handle.

	She looked up at me with a funny smile, still showing some embarrassment.  I...  I can 
get you one of the motors.  Were her nipples sticking out a bit through her blouse?

	I changed topics a bit.  Okay, that will be a big help.  I still have hardware choices to 
make.  Do you want any feedback that its working?  A light?  Sound?

	She responded when I said, feedback with a look of shock or surprise, then smiled and 
said, No sound, a small light would be okay.

	We talked a little more.  I let her know that I could either run the motor full off to full on, 
or possibly let it run at a slower pulsed rate, then kick it up to full, she should think about it.  
She told me shed like a way to turn it off quickly; I let her know that wouldnt be a problem.

	We took a break to visit the plumbing; she got her bag and we went out to the bus stop.  
Since it was an earlier bus than usual for us, we got seats easily; where I got on, I usually got a 
seat, sometimes Emily didnt.  I told her Id be sure and save her a seat from now on.

	Once we started out, both of us reclined our seats.  I was sitting next to the window, 
Emily to my right.  I looked over to her and held out my right hand.

	Emily, Im going to close my eyes.  I want you to pretend Im not here, and my hand is 
the button for your controller.  I want you to go through how youd normally use it, rates, 
durations, as best as you can figure.  I need to know this to set the timing parameters.  When 
youre through, squeeze my hand.  Okay?

	She looked a little hesitant, then nodded.  I smiled, leaned back, and closed my eyes.

	After a bit I felt her hand on mine, it felt like her right hand reaching over.  I moved my 
hand out a little, and she set it on a book in her lap.  She started out tapping on the back of my 
hand slowly, evenly, about twice a second with her middle finger.  Okay, I thought, this is easy, 
tenth of a second sampling will work.  Then she started speeding up; tenth of a second is too long 
a sample interval.  Then the on time started getting longer than the off time, until it was on 
for a little more than a second, and off briefly.  Then it was on continuously for quite a 
while, a minute or so, then she squeezed my hand.

	I pulled my hand back into my lap and thought.  Okay, use about five hundredths of a 
second for the sample interval, and a set of sixteen bit counters.  How long do we have to go 
before we declare on continuously?  12.8 seconds would be overflow from the lower 8 bits to 
the upper 8 bits, a convenient point.

	I opened my eyes.  Her eyes were closed; it looked like she was perspiring, and breathing 
a bit fast.  Emily? I asked.  She opened her eyes and smiled, again giving me a sort of blush.

	I smiled back.  Like to talk design decisions a bit?

	She said, Sure.

	We talked about timing; I gave her my initial ideas, letting her know we could alter things; 
this was just a first hack.  She agreed that about ten to twelve seconds was a good point to go to 
continuous on for her mystery motor.  We both understood the nature of software; you build 
the first version expecting to learn a great deal, and expecting to throw it away.  When I asked if 
there was anything else, she surprised me.  She lifted the armrest between the seats and said, Id 
like to hold your hand again.

	I held out my hand and she took it in hers gently.  Then she leaned on my shoulder and 
closed her eyes.  That seemed to be the thing to do; I did the same, and was soon asleep.

	Luckily we watch out for each other on the bus.  I woke up with the driver announcing a 
stop two from where I get off.  Emily squeezed my hand; I looked at her and smiled, she had a 
very peaceful look on her face.

	Where do you get off? I asked her; she was always on the bus when I got on in the 
morning.

	The stop after you, she told me, with a chuckle in her voice and a little blush.  What 
had I said that was so funny?

	Would you like to go out to dinner with me tomorrow? I asked.  I promise not to talk 
about the project for you if you dont want to.

	She laughed.  That would be nice.  Id like that.

	Good, I said, standing up and grabbing my bag.  Ill see you tomorrow morning.  
Sweet dreams.

	She laughed and blushed again, putting a hand up over her face.  I got off the bus 
wondering what the hell was going on, what was I missing?

	I pretty much finished the code that night, testing it with my light emitting diode, and 
prototyping the motor driver.  I sat at my workbench in the spare bedroom pushing the button 
for a while, then watched as it took over repeating the pattern.  I could speed it up, slow it down, 
or turn it off; not bad.

	The next morning when I got on the bus Emily had saved me a seat.  Good morning. I 
said as she picked up her bag for me to sit down.  She dug into hers and pulled out a little plastic 
bag with a small motor in it; she had a Band-Aid on her hand.

	I took the offered bag and asked, Cut yourself?

	She laughed and said, Yes, but not bad, not being careful enough.  Ill stick to software.

	I took the motor out of the bag and looked at it.  It was about the same diameter as my 
thumb, a little over an inch long.  It looked like something had been pulled off one end of the 
shaft.  I tried turning it with my fingers; it didnt want to budge.  It was either very powerful or 
destroyed.  Id do an autopsy later.

	We talked for a bit about dinner and the upcoming day.  Shed made reservations for us 
for dinner at a fish place we went past on our side of the bay; that way we could take local 
busses home anytime we wanted.

	We settled back into our usual morning routine, except that she once again lifted the 
armrest between the seats, took my hand, and leaned on my shoulder.

	We snoozed again, waking when one of her cow-orkers called her name just before her 
stop.  We both sighed and smiled; she touched my cheek with a hand as she got up.

	I got a closer look at the motor later that day; it was trashed.  I got it to turn, but the 
brushes were destroyed.  But that wasnt what I was thinking about; shed touched me and 
smiled.  That felt so wonderful, and yet at the same time reminded me of how empty my life 
was.

	I got on the usual bus home that afternoon, saving a seat for Emily.  She was lucky; if I 
hadnt she wouldnt have gotten one.  We settled in and I asked, Read?  Are you going to read 
on the way home?  She raised the armrest in reply, and reclined her seat.  I did the same.  As I 
was offering her my hand, she reached an arm around me and pulled me over on to her shoulder.  
How could I refuse an offer like that?

	Our driver announced the restaurant name loudly over the intercom, waking us.  Emily 
must have told him, as it wasnt the usual stop for either of us.  We got off together thanking 
him, and our arms went around each other as we walked from the bus stop.

	Dinner was good, but got off to a slow start.  I didnt know what to say.  We worked for 
competitors, so we both knew work discussions were no good.  I told her I wouldnt talk about 
the gadget.

	After a few minutes, though, she squeezed my hand and said, Roger, whats the matter?

	I shook my head, closed my eyes, and quietly explained my dilemma.  When I heard her 
laughing softly, I opened them again.  I hadnt mentioned that watching her breasts was not doing 
well for my concentration.

	She told me she understood.  She was mildly surprised I didnt have a steady girlfriend.

	I smiled and told her I was between girlfriends; Id learned that no matter how well you 
think a relationship is going, if one person says it isnt going well, theyre right.  I still wasnt 
sure what had happened; well, she was sure shed found someone better.

	We waxed a bit philosophical after that.  She visited the ladies room, and when she 
returned to the table her blouse was unbuttoned substantially, and I could tell her nipples had 
perked up.  I took a deep breath when I noticed that, then looked in her eyes.  She gave me a very 
intense look and a smile; no accident there.

	We more or less split the check.  We walked back to the bus stop arm in arm.  Shed put 
on perfume and it was driving me crazy.  When we got to the bus stop, we stood there looking at 
each other.

	Well? she asked me.

	I sighed.  Emily, Id like to kiss you and squeeze you and...

	I was interrupted by her closing her eyes and pulling me to her.  I put my arms around her 
and we kissed.  I held her gently, arms around her shoulders.  Too gently it seemed; she turned 
me around so my back was to the side of the bus stop and pressed into me from hips to 
shoulders.  I felt her waist as we kissed, moving my hands up her back.  I could feel her nipples 
burning into me.  She moved one of my hands to her front; I gently squeezed a breast and she 
moaned as we kissed.

	We broke for air a little before the bus arrived.  We stood there looking in each others 
eyes with the bus waiting there until the driver yelled out, Next bus is in twenty minutes.  You 
getting on?  She pulled me to the bus; we grabbed our bags and got on.

	We didnt get seats, so we stood there in the aisle holding on to each other, then kissing.  I 
didnt know what to do as we got to my stop.  Should I ask her to come with me?  My 
indecision let her make the choice.  She squeezed my hand and said, Heres your stop.  Ill see 
you in the morning.  With that we got in one more deep kiss, and I got off the bus.

	I sighed as I stood there watching the bus pull away.  Then my legs went on automatic 
pilot and took me back to the house.  Nothing but junk and bills in the mail; it looked like I had 
two choices for the evening.  I could take matters into my own hands, or I could go for 
sublimation and work on the gadget.  I wanted to take another whack at that motor, and I thought 
I had something similar in a junk box in the garage.

	It only took me a few minutes to find a similar motor in a box in the garage.  I took a look 
at the one shed given me under a magnifier; the brushes were shot, really worn out.  I hooked up 
my junk box motor to the prototype and tried it.  I put the motor between the soldering iron and 
a large transformer to keep it from hopping all over the bench as it pulsed on and off.  I had to 
add a little more snubbing on the motor and the mosfet switch, but it worked like a charm.  I put 
the switch/LED combination on the end of three feet of wire, and the motor on a longer piece of 
wire.  The remaining circuitry was on a small piece of copper circuit board about an inch on a 
side.  I fooled with the code for too long, finally flicking it in for the night.  I have to get up early 
for the bus.

	I was brushing my teeth when I thought of that motor hopping around.  Could that be it?  
I looked at myself in the mirror.  That could be it; the timing was right.  Oh well, well find out 
soon.  I rinsed my mouth and went to bed.

	When I got on the bus the next morning I didnt see her at first, then I noticed her farther 
in the back.  I sat next to her; shed already pulled the armrest up.  Hi.  Thanks so much for last 
night.  I... I spoke as I put my bag down on the floor.  When I sat up again she flung her arms 
around me and pulled me to her.  I didnt need encouragement.  We kissed and our hands roamed 
all over each other, touching, squeezing, feeling, digging in with fingernails.  At one of the stops 
we heard a gal walk by and say, Oh wow.  Nerds in lust!  We laughed at that and came up for 
air.  Wed seen and heard some pretty torrid stuff on the bus.  I never thought Id be part of the 
show.

	As we got close to her office I had a hand inside her blouse, feeling her through her bra.  
She had a hand inside my shirt as well.  She made a mad dash at rearranging herself, kissed me 
once more, and scrambled off the bus leaving me panting.  Damn, I didnt tell her about the 
motor.

	A few minutes later I got off at my place.  One of my coworkers on the bus, a gal in 
marketing, complimented me on the show wed put on.  I smiled and thanked her; I hoped wed 
do it more often.  As we walked up to the building though I could feel a very bad case of blue 
balls -- I hurt.

	I gave Emily a call about half an hour later.

	I dont think Ive ever enjoyed a bus ride as much as this morning, I told her.

	She laughed, eventually saying, I enjoyed it as well.  And dinner last night.

	We chatted for a couple of minutes, then I told her.

	Ive got good news and bad news.

	Oh?

	The good news is that Ive got what I think is an operating prototype.  The bad news is 
that the motor you gave me yesterday was dead.

	Hmmm...  Ill think about that.  She sighed for a bit, then laughed again.  Well talk this 
afternoon.  Save me a seat in the back.

	Ill save you a seat.  Im looking forward to seeing you again, holding you.

	That got a sigh.  So am I.  Ill see you this evening.  Think about me.  Bye.

	Bye.  I hung up the phone.  Think about her?  How could I not think about her?  What 
if my guess was right?  She seemed to be interested in me, I wanted her very much, yet was 
worried about chasing her off.  I needed her very much.  I thought Jennifer and I had been so 
happy, things had been going so well.  Id been wrong; it hurt then and it hurt now.  I know she 
was just out of college; she told me, People grow, they change.  I know that; I thought we 
could grow together, change together.  Had I just been a convenient transition out of school, as 
Susan said?  Sigh.  Introspection can be painful.  But waking up alone in the morning is even more 
painful.  For the last few months, how many months had it been since she moved out?  Id 
thrown myself into my work, into side projects, working out.  My boss was happy, the people I 
built gadgets for were happy, so why wasnt I?

	That was a very long day, and a very slow bus getting to her office.  I smiled when I saw 
her; she had a big grin on her face.  I was sitting next to the window.

	Scoot over so I can have the window, she said.  I scooted over and started to stand up.

	No, Ill slide over, she told me.  Then she sat on my lap and gave me a slow sensuous 
wiggle before sliding over to the seat, just as I was about to grab her breasts from behind.

	I probably looked dazed; she asked, Did you have a long day?

	I told her I did; it had gone very slow.  Id also stayed up too late working on the gadget.

	She said, Then you can rest on the way home.  She pulled my arm and put a hand 
around my neck, pulling me into her lap, resting my head on her soft full bosom.  I sighed; make 
that a soft but firm and perfumed bosom; she smelled delicious.  I could smell her perfume, feel 
her warmth, hear the beat of her heart.  My mind spun for a while and then I surprised myself; I 
went to sleep.

	She woke me with a squeeze.  I took another deep breath of her (stolen from silli artie at hotmail dot com) perfume and kissed her 
through her blouse, then sat up.  Thank you.  I miss naps.

	She chuckled.  We should do that more often, it was nice.

	No, it was incredible.  See you in the morning?

	She gave me a smile and put a hand on my leg.  I thought I could bring over another 
motor tonight, say around eight?  Would that work?

	My mind almost stripped its mental gears as I went from delirium to shock.  The place 
was pretty clean, I should take care of the kitchen.  Im pretty neat and tidy all in all.  Should I 
give the bathroom a quick going over?

	That would be great.  Bring the motor, whatever you need.  It shouldnt take long.

	She leaned back and with a raised eyebrow said, I was thinking of bringing my pillow...

	I didnt know what to say.  She started laughing and reached up and closed my mouth.

	This is your stop.  Ill see you at eight.

	I got off the bus.  Gee, last night when I stood here I was dazed.  Tonight standing here 
Im dazed.  Oof, Ive got some work to do.  Pillow?  It doesnt matter if I was right or not, I 
guess.

	I headed home and had a quick bite to eat, then did a whirlwind job on the bathroom and 
the kitchen.  I was almost thanking my parents for harping at me all those years and turning me 
into a neat freak.  I live in a little three bedroom house.  One of the bedrooms is a real bedroom, 
one is an office - workshop for electronics and computer stuff, and the third is the library - guest 
room with a futon.  Id just finished a dusting pass when the doorbell rang.

	I answered the door; I guess I was out of breath, because as soon as she saw me she 
started laughing.  She was carrying her work bag, a small suitcase, and a pillow.  I stepped to the 
side and invited her in.

	Been busy? she said as she put down her things and gave me a kiss.

	I was going to answer but got distracted.  We kissed and hugged.  She handed me an old 
copy of The Economist; thats how she had my address.  Give me the tour?

	I gave her the tour of the house.  She remarked how tidy things were; I told her it was the 
result of many years of beatings; I kept the place pretty well picked up.  She sat down on the 
futon in the library and leaned back, as if she was trying it out for size.  She looked delicious.  
How was this going to unfold?  What should I do?

	We ended up in the office.  I pointed to the prototype, sitting on a piece of circuit board 
in a small vise on the bench, the batteries, switch, and motor hanging off on wires.  Well, there it 
is.  Wheres your motor?

	She looked around the room a bit.  Can we move this into the other room by the futon?  
She picked up the switch and pushed it a few times, watching the motor go on and off at the 
same rate.  Did I see her nostrils flare?  The way she looked at that motor, I had to be right.

	Sure, I told her, I can move it in there.

	She hit the switch quickly and the motor turned off.  She gave me a very intense look and 
said, Good; why dont you move it in next to the futon and get whatever youll need to connect 
up the motor; it already has a wire going to it.  Im going to the bathroom and then Ill join you.

	She stepped out and I moved the gadget to the little table next to the futon.  I got my wire 
cutters, and the soldering iron as well.  I was thinking what other tools Id need when she came 
into the room carrying a small paper bag.

	Do these lights dim, or do you have any candles?  These are pretty bright.

	I hit the switch, dimming the lights down.  Hows that?  I may have to put them up 
again to connect the motor.

	She smiled and sat on the futon.  Her shoes and socks were off; her blouse half 
unbuttoned.  She reached in the bag and pulled out a little plastic battery holder with a switch on 
the side, a wire going to the other end still in the bag.

	Here.  You can cut this off and hook it up.  Leave the other end in the bag for now.

	Okay, I looked at the wire; two conductors, should be safe.  I clipped off the battery box, 
stripped the wire ends, cut off my old motor, and spliced the wires together.  I looked up at her, 
waiting for her to make the next move.

	Can you get me a small towel? she asked.  And dim down the light a bit more?

	Of course.  Be right back.  An encouraging sign; I dimmed the light some more then 
went to the bathroom and grabbed a towel off the bar.

	When I walked back into the room I was stunned.  I knew what was going to happen, but 
I didnt know what she was going to do.  Shed taken off her blouse and her pants, and was 
taking off her bra.  She smiled to me and pointed to a spot on the floor next to her.  Have a seat.  
I want to show you what youve made.

	I sat down on the floor and handed her the towel.  Her nipples looked magnificent.  She 
got up a little and put the towel underneath her, then slipped off her panties.  She looked me in 
the eye as she pulled the wire out of the paper bag.  At the other end of the wire was an egg 
shaped thing, maybe two inches long and an inch or so in diameter.  She relaxed back on the 
futon, still looking me in the eye, and put the egg in her mouth for a moment.  She seemed to roll 
it around, turning it, then she took it out and with her legs together slowly slid it down her 
thatch, using her other hand to spread her lips gently and position it.

	Both of us were breathing heavily.  I had the erection of my life, and her nipples were 
crinkled and pert.  I thought I could smell her scent as well as her perfume.

	She picked up the switch, leaned back, and tapped the button a few times.  Ooh! she 
moaned, moving her hips and hitting the button.  After a few seconds she let the switch dangle in 
her hand.  In the dim light of the room I could see the LED blinking on and off as she writhed on 
the futon.  I remembered to breathe again.  She hit the button again, changing the rhythm, 
speeding it up.  After a few seconds more she changed it again, this time more on than off.  I got 
up and moved to her, touching a breast gently.

	Her eyes sprang open, wide with a glazed animal look as she hooked her other hand 
around my neck and pulled my head to her breast.  I latched on to her nipple and put my hands 
around her waist as she moaned more, arching her back, holding me to her.

	After not too much longer I felt her stiffen and a low, long cry started coming out of her.  
I held her to me, feeling her warmth, tasting her, hearing her pleasure; she squeezed me and pulled 
my hair, then went limp on the futon and in my arms.  I sucked contentedly for a while, then 
moved to kiss her other breast, then rested my head on her, feeling the warmth of her chest and 
hearing her heart beating rapidly.

	It took a while for her breathing to settle.  She moved a bit and I sat up, putting a hand on 
her knee and moving it slowly up her thigh.  I wanted her, especially after that show.

	She smiled.  It works.  That was great.

	I shook my head.  She laughed then growled, Strip!

	I started peeling off my clothes.  She stood up slowly, letting the switch and the vibrator 
fall to the futon, then pulled the futon out full length.  When I was naked she pointed to it and 
said, On your back.

	I moved over to the futon and lay on my back.  She reached into the paper bag again and 
pulled out a little foil package, opening it and taking out a condom.  She moved next to me on the 
futon and with one hand caressing my balls, put the condom on me with the other.  Sit up, she 
told me, Please.

	I sat up on the futon, and she sat in front of me, then moved into my lap, taking me into 
her.  I crossed my legs and she rested on me, wiggling into place.  I moaned and my eyes closed, I 
leaned back, my arms behind me propping me up.

	Then I felt something else and opened them again; she was sliding the vibrator back, now 
positioned between the base of my cock and her nether lips and clit.

	Sit up and kiss me, please, she said softly.

	I sat up and put my arms around her, feeling her breasts against me, and we kissed.  She 
moved her hips slowly side to side.  I leaned my head down a bit and suckled her again; shed put 
perfume on her breasts, something I love.

	After a while she pulled my head up again.  Are you ready? she asked.

	I was about to say something when she closed her eyes and tilted her head to the side; I 
closed mine and we kissed.  As I slid my arms around her waist to hold her I felt the vibrator 
start; that pulse of pleasure when it first turned on was incredible.  It seemed there was another 
pulse when it turned off.  She played with the timing for a bit; we were both moaning, she was 
rocking on top of me.

	I couldnt hear the vibrator, but I felt it throughout my body as it pulsed on and off.  I felt 
her weight on top of me, her warmth.  I could feel the warmth of her breasts against my chest, 
feel her breasts moving as we breathed, feel and hear the warmth of her breath on my cheek, hear 
our moans.  I had one hand at the base of her spine holding her to me, the other up near her neck, 
feeling her skin and covered by her long hair.  Every caress of her hair as she moved, every pulse 
from the vibrator held between us sent another shock of pleasure through me.

	I pulled my mouth away from hers and panted in her ear, I cant take much more.

	In response she stuck her tongue in my ear and the vibrator stayed on as she rocked 
against me more.  I slipped back and she leaned forward.  I couldnt hold myself up anymore, I 
started coming inside her as I heard that low wail start in her again.

	I collapsed on my back; she rode me, moaning as I pulsed into her.  Finally she pulled the 
vibrator out of the way and leaned down on top of me, kissing once again.

	She slid off me and gave me a nipple for a while.  I took a deep breath and moaned as I 
sucked on her.

	I hoped you liked tits, she said as she held my head to her.

	I flopped a hand up on her waist; she pulled back a little.

	I looked at her.  She had a wonderful satiated smile.  I felt dazed and undoubtedly looked 
it.

	Thank you for a great gadget, she said.

	Youre welcome.  Thanks for trying it out.  I think I could get better with practice.

	She laughed and shook her head, her long hair coming down around her face and into mine.  
My eyes closed and the world spun a bit more.

	Theres just one problem with it, she said.

	I forced my eyes open as she moved her hair out of my face.  I can put it into a small 
enclosure, thats no problem.

	She shook her head gently side to side, then moved back up giving me a nipple.  No, 
thats not it.  Why should I use that when Ive got its inventor?  I held on and we rolled on our 
sides on the futon.  A good question indeed.  I left one nipple and let my head rest on her chest.  
Of course this is only a prototype, well need a lot more testing.  She laughed and squeezed 
me.  I closed my eyes to her warmth and softness, to the feeling and sound of her heart.

	We got up after a bit, both on wobbly legs.  I laughed as I thought over the last few days, 
thinking about that motor with the worn out brushes, imagining the hours of ecstasy it took to 
get that way.  I went to the bathroom and posted my French letter.  When I got back to the room 
she was folding up the futon, on her knees on the floor, leaning over it.  What a marvelous bottom 
she has; firm and soft at the same time, such an incredible cushion for making love.  I got down 
behind her and pressed in.  She moaned and wiggled appreciatively, getting my interest up again 
dramatically.

	Ready for another test already? she asked, wiggling into me.

	I put my hands on her shoulders and pulled a bit.  The price of progress.

	She laughed and tossed me another condom.  I put it on and she grabbed a pillow and the 
towel, putting them underneath her.  I saw the vibrator snake down again and she leaned forward 
a bit, spreading her legs.

	What a beautiful sight; I felt her gently with one hand, sending shivers down us both, then 
guided myself in.  I slid against her, in heaven again, the sight of her on the futon before me, her 
breasts squashed out a little on her sides.  I felt the warmth between her legs and the smooth 
cushion of her ass.  I thought I smelled her aroma mixed with her perfume and inhaled sharply as 
I slid my hands up from her bottom to her shoulders, feeling that soft black mane.  I felt the 
vibrator start up its pulsing again.  It felt more distant this time; sitting against the base of my 
cock had been intense.

	Mmmm...  Thats nice, I said.  Let me know when youre close to the edge; I think I 
can last a while like this.

	She moaned and wiggled underneath me.  I leaned on her, feeling her back and squeezing 
her shoulders, feeling her sensuous ass supporting me.  She changed the rhythm and I started 
sliding in and out of her trying to match it.  After a bit we got synchronized, then she started 
calling out, Faster...  Deeper...  I moved with her as best I could; I felt the vibrator go on 
continuously and I pressed into her as she started her moan.  I pressed and wiggled, I was very 
close as well.  Then as we moved it felt like the vibrator touched my left nut; the shock set me off 
and I froze, pushing and pulsing into her, then collapsing on top, covering my face with her long 
hair.

	It took us longer to recover.  We pulled apart and lay in each others arms, half on the 
futon, half off.  I heard the mantle clock in the other room strike ten.  We both started moving.

	We should get to bed if we want to make the bus, I told her.  Or, we could just say 
were telecommuting tomorrow.  Its Friday.

	She kissed my chest and said, No, Ive got meetings.  But its a wonderful idea.

	We kissed again standing up on our knees, then cleaned up and went to bed.  We agreed 
on setting the alarm earlier to give us time to shower and get ready in the morning.

	The alarm went off and I whacked it.  I started to get up when she pushed me on to my 
back and flipped the covers down.  I started to say something, then felt her hands on my cock.  I 
lay back and enjoyed it.  She pulled my T-shirt off and knelt between my legs.

	After I got hard between her hands she moved and I felt her breasts on me, soft, then 
hard, then soft again.  I started moaning and moving on the bed.  I must have said something, 
because she said, Im not going to stop, enjoy it.  Then I felt a hand on my balls, and her soft 
hair between her breasts.  It was too much for me; I gave another moan and came, feeling the 
warmth spread on my belly.

	Oh God, that was incredible, I panted.

	She laughed and said, Ive wanted to do that to someone for a long time.

	Any time you want... I laughed.

	We wobbled to the bathroom and showered together.  I knelt between her legs and started 
kissing her.  She moaned and held me to her for a moment, then said, Stop...  Well miss the bus.  
Weve got all weekend.

	We managed to get to the bus on time.  When we got on, together, a bunch of the regulars 
whistled and applauded.  I felt myself blushing.  Emily just smiled.  We sat down and collapsed 
in each others arms.

	I was still half asleep when she kissed me and got off at her stop.  See you tonight, she 
told me.  I gave her a squeeze and a sigh.

	I got off at the salt mines and walked in.  The same gal that talked to me a few days earlier 
walked along side and said, Pretty subdued this morning -- have a long night?  I looked at her 
and smiled; I didnt know what to say.  She laughed and clapped me on the back.  Good for 
you!  Good for you both!

	We necked nonstop on the bus going home.  She went to her place to get some more 
things while I started dinner.  She learned that night that just because Im neat doesnt mean I can 
cook; she told me shed do the cooking when we were together.

	We worked on the gadget.  We toyed with proportional control, switching the motor 
between a low speed and a higher speed.  This was pretty wild work; Wed code a bit on my 
laptop, then download into the PIC, and shed lean back on the futon and try it.  Wed get to the 
point where one or both of us was too delirious and wed make love again.  We finally settled on 
a low thrumming and full speed.  Of course by then I dont think she could focus or walk, but 
then again she didnt care.

	Saturday afternoon she was laying on the futon, blissed out, the vibrator thrumming 
between her legs, pulsing gently.  Shed been like that for a few minutes.  I couldnt take it 
anymore.  I spread her legs gently; she whimpered a bit, but I put a hand on the vibrator and held 
it in place.  She moaned and relaxed.  I knelt down closer to her and slipped it inside her to a gasp, 
then put my lips in its place.  I could feel the heat; her scent was delicious as her curly thatch 
tickled my nose and the warmth of her thighs squeezed my head.  She had one hand on my head 
and one on the switch.  I followed her timing as best as I could; shed have us moving in synch, 
then in a contra rhythm.  She whimpered a little and I tugged a little on the wire, pulling it taut.  
Her thighs sprang tighter around my head and she started moaning and moving in earnest, going 
limp half an eternity later.  I pulled the vibrator out of her with a soft plop.  On impulse I put it 
to my lips and tasted it.  It was warm and delicious.

	Thats how the weekend went until late Sunday; she needed to go home to get ready for 
work.  We agreed it had been the most intense development work wed ever done.  And, the most 
satisfying.

	The next two weeks had us sleeping over at one place or the other most nights.  She had a 
small apartment; I convinced her to bring her laundry over and use my washer and drier rather 
than feed money into the machines in her building.  We squabbled about minor things, learning to 
live with each other.  I quit cooking save for breakfast on the weekends.  I also learned that she 
could eat much spicier food than I could, getting cleaned out by her family Vindaloo recipe.  I 
stayed home the next day, telecommuting between my little office and the bathroom.

	We refined the gadget, packaging it up to make it portable.  Sometimes we used it when 
making love, sometimes we didnt.  She got her period and spent a few evenings with me 
massaging her feet while she lay back on the futon, blissed out to the thrumming between her 
legs.  She also gave me the most incredible blowjob Ive ever had, combining her lips, her breasts, 
and her hair, and told me that when her period was over, we were getting rid of the condoms, she 
was back on the pill.

	We love doing things together; Ive really enjoyed going out again, doing museums, parks, 
dining out.  She lets me be in charge, lets me think Im in control.  But I know all she has to do is 
get a nipple in my mouth, wiggle her wonderful bottom up against me, or wave her soft perfumed 
hair across my face, and Im helpless.  She loves to get me on my back, riding me with or without 
our battery-powered friend.  The only thing I can do is hold on.

	And I know when shes helpless as well.  Shell start out on the futon with the vibrator 
between her legs, and after her head drops back, Ill move up and slide a finger deep into her, 
hooking back to get that magic spot while I move the vibrator around with my other hand.  I 
know she wants me inside her; I want her as well, and once shes at the edge Ill take my finger 
out and enter her, taking her the rest of the way.  Or, Ill slide the vibrator into her and go down 
on her, feeling her wonderful thighs holding my head and muffling her cries.

	*

	Another morning on the bus; I got on at my usual stop.  Emily was in the back, saving me 
a seat.  I sat down next to her and gave her a kiss.  So when are you going to move in with me? 
I asked her once again, almost a ritual greeting.

	She smiled and said, How about next weekend?

	I gave her a big hug.  Oh, thank you. I hugged her and let my hands roam over her body.  
My left hand came up with a wire sticking out of her clothing.  I leaned back and looked at it; a 
suspicious wire going to a little switch with a light emitting diode.  I looked at her and chuckled.

	You said you might not be going in today, she told me smugly.  I didnt want to be 
bored on the bus.

	I handed her the switch.  We leaned our seats back.  She took a slow breath and tapped 
the switch gently.  I couldnt hear it over the noise of the bus, but I could see her eyes half close 
and a little shudder go through her.  She let her eyes close; I looked down at her hand.  She was 
gently holding the switch, not touching it.  I could see the LED blinking on and off.  She hit the 
switch a couple of times setting a new rhythm.  I gently squeezed a breast, eliciting a moan and 
another shudder.  As I leaned over to kiss her, I put my hand on her mound and pressed gently, 
feeling the pulsing vibration.  I thought of how rewarding design work was when you have a 
satisfied customer.
