 WITH A LITTLE HELP FROM MY FRIEND (MMF, mast, exhib, voy)
   I've posted this story on another story site long long ago but this
version is the whole truth as it happened.  I'm sorry if it's a bit long,
I'm one of those guys who likes to provide a lot of context.  Hope you
enjoy this story from my life as much as I did remembering it.
   Some years back my wife Trish and I enjoyed taking nude pictures of each
other.  Although we would often do fairly elaborate setups at home with
props and backdrops, we also would also do public nudity photos as well. 
We would pose on public beaches where we were reasonably sure we wouldn't
be exposing ourselves to children or families and often we would pose on a
dare in more unusual and exciting settings.
   As an example, one time we were outside the fence bordering a large
factory that was about to do a shift change.  Trish started to undress with
her back to the leaving workers as I took shots from her front using the
workers as a backdrop.  We were nowhere near the gate and the fence was
quite high so she felt quite secure that no one would be grabbing her.  It
didn't take long for the fence to be lined with a happy group of noisy
onlookers.  She eventually turned around and gave them the full show and
even walked up to the fence for close ups.
   We had many such sessions and the end result was invariably great sex as
soon as we got home or sometimes in the car or some secluded area if we
couldn't wait.  Over the years we amassed thousands of photos and memories.
   One morning I was on my computer searching Ecards for my friend Jack's
birthday.  Jack is a very old and close friend and we have known each other
since childhood.  On a whim, I took one of Trish's pictures and added a
little speech bubble to her mouth with a happy birthday message.  I saved
the picture and attached it to an email destined for Jack.  It felt really
naughty as I pressed send since we weren't in the habit of showing off our
photos even to close friends.
   The next morning Jack's reply was sitting in the inbox.  He was so
excited he just kept gushing about how cool it was that my wife would pose
nude for a birthday picture and how incredibly erotic he thought it was
because it was Trish, his best friend's wife, a woman he'd known for more
than 15 years.  For him there was a whole forbidden fruit quality to the
act that really turned him on.  He was even more turned on when he found
out that she was unaware of the gesture and that I had picked the shot out
of thousands of others.  He pleaded with me to send him some more shots
which I did, reluctantly, as long as he promised not to share them or tell
anyone of their existence.
   As it turned out Jack had also been fond of taking pictures and videos
of his ex-wife and girlfriends.  Although his pictures were more in the
category of porn I had no objection to seeing them and had many a
satisfying jerk-off session looking at them as I'm sure he also did to
Trish's shots.
   One day while I was on the computer, I got up to get myself a cup of
coffee.  A minute later Trish came into the den looking for a pen from the
desk and noticed several emails from Jack, all with attachments.  Thinking
it was just boys being boys sending some naughty pictures to each other,
she opened one to find several pictures of Jack and his ex Gail in various
explicit poses.  She was shocked, especially when she saw that this message
was a reply to one that I had sent earlier.  She then went on to read
Jack's reply `Thanks again for those new shots of Trish, my dick thanks to
too.  Here are a few more shots of Gail, enjoy.'
   When I got back to the den I knew instantly something was wrong by the
look on Trish's face.  When I saw what was on the screen I knew I was in
deep shit.
   "How long have you been doing this and with how many others?" she
demanded.
   I told her the whole story and she was very relieved to hear that I had
only included Jack.  She really shocked me when she said, "I'm not happy
that you chose to do this behind my back and I'll figure out what to do
about that later but Jack is like family and I find it a little exciting
that he's looking at my pictures and masturbating, I guess you can keep on
doing it but only with him, no one else."
   Not believing my good fortune I continued sharing shots with Jack but
never told him that Trish was aware.  Trish would even pick photos for me
to send and would often look at the shots Jack sent in return.
   Now it's important you know something about Jack.  As I mentioned
earlier, we grew up together in another city.  Like most young friends we
had sleepovers and of course jerk off sessions while sharing magazines or
just wanting to relieve ourselves of all that pubescent sexual energy.  On
a couple of occasions we even tried mutual jerking but that was it, nothing
else.  Now I am an average sized guy, nothing to really brag about but
nothing to be ashamed of either.  Jack, on the other hand, is a little
better endowed than most guys.  Not huge, but a very respectable thick 8
inches or so.  Enough to be noticeable and Trish did notice more than a few
times when reviewing the pictures he sent.  She only mentioned it a few
times remarking on what a big boy he was but I could see her linger as she
reviewed the pictures and I was pretty sure she wasn't looking at the
women.
   As I said, Jack and I were raised in another city and while business
called me away to a new home, Jack never moved so we would only see each
other on vacations or business trips.  About six months after we had begun
to exchange photos Jack arrived in town on business and was dropping by for
dinner that evening.  Since I had never told him that Trish was aware of
the picture swapping Trish saw no potential discomfort in his visit. 
Please don't think we're prudes, you have to realize that this was before
social networking, sexting and all the other exhibitionistic norms of
today. This was just the beginning of the digital age and nudity was still
a really exciting thing and a bit risqué to put your self out there.
   Jack arrived and we had a pleasant evening of food and drink after which
Trish went down to the family room to watch TV while Jack and I caught up.
After a while Jack said in a lowered voice how happy he was with our little
arrangement but that he was quickly running out of material to send me.  I
told him it was no problem and that I would be happy to continue without
him reciprocating.  He asked if I had shot anything recently and could he
have a look at them.  Since Trish was downstairs I invited him into the den
and started to show him some of the more recent shots we had taken.
   We paused on a picture of me and he was quite surprised that I also
enjoyed posing.  I told him that I really got into it and found it to be a
real turn on.  He asked if we ever did sex shots and I said although we did
try a few times, that they never turned out well.  Then I joked that I
thought he wouldn't be interested in staring at my dick anyway.  Without
thinking I added, not as much as Trish seemed to love looking at his
honkin' piece of meat.  Unable to take back my words I looked at Jack whose
look of surprise quickly turned into a sly smile.  "Well...  there's a lot
more going on here than I thought," he continued to smile, "I guess Trish
must be too shy to have this out in the open?"
   Just then Trish walked in asking if we wanted our drinks refreshed and
looked over to see me in full screen glory on the computer.  She stood
staring for a moment until we both realized what she was looking at.
   "Well this is new, just what are we up to here?" she asked.
   Nervously I confessed to showing Jack the latest shots and how he now
knew everything.  I even blurted out our discussion about the sex pictures.
I think the two of them were quite amused at my discomfort until Trish
heard the words sex pictures.  Surprisingly, she just said that the only
pictures we had were terrible and she didn't want them seen by anyone.  "We
could never get the remote working properly" she continued "and we were
always out of frame, out of focus or just plain not sexy."
   Jack said he understood but he had shared many such pictures with us and
we seemed to be OK with them.  Reluctantly Trish went over to the computer
and pulled up the folder with the few sex shots we had kept over the years
and started up the slide show.  As we all looked on Jack began a sort of
critique saying that if the camera had been over here or there some of the
shots would have been terrific, then came the bomb.  He looked us both in
the eye and said that he could tell us right then how to fix all the
problems, we should let him be our photographer while we had sex.  He
continued to say that he had never watched a couple have sex and the
thought of doing so was an unbelievable turn on.  He then added that this
would be purely voyeuristic on his part and promised that he wouldn't try
to join in, unless he was invited of course.  Trish and I both broke out
laughing.  The laughter turned to shock though when Trish replied in a
devilish tone that if I was all right with it, that he could do it but only
under one condition.  Jack would have pose for her first.  The counter
offer had a strange effect on him, he seemed both excited and reluctant at
the same time.  Snapping out of it and realizing the opportunity at hand be
agreed.
   "Great, let's get started then" she barked.
   "Right now?" Jack and I both chimed in.
   Without answering, Trish left the room and returned with the camera. 
Looking around the room she told jack to sit at the desk and start going
through her nude pictures as if he were at home alone.  Slightly
bewildered, he did as he was instructed.  Then she told him to pretend he
was alone and slowly start playing with himself through his clothes and to
start disrobing as it felt natural and to do whatever he might do at home
including masturbating or whatever else he wanted to do.
   Jack seemed to have no problem at all slipping into the roll, he started
going through all the pictures stopping and zooming in from time to time
and as he did he almost unconsciously began to rub his crotch, first on top
then undoing his belt and slipping his hand inside.  All the while Trish
circled like a vulture taking shot after shot and getting visibly hornier
by the moment.  At one point she stopped to consider an angle I suppose and
almost unconsciously her hand slipped down between her legs gently rubbing
her sex.  Jack raised his hips, sliding his pants and underwear down to his
knees exposing his full manhood.  This snapped Trish back to reality as she
continued snapping shots from all different angles and proximities.  At
times she had the camera only inches from the head of his penis.  All the
while he just sat there looking at the photos, softly caressing the tip of
his phallus.  Jack unbuttoned his shirt and letting it fall open exposing
his chest and now wrapping his fist around the shaft began a slow and
deliberate pumping motion.  Before long he stood and slid his pants and
underwear to the floor and stepping out of them he also removed his shirt.
He sat down again and leaned forward to remove his socks and complete the
picture.  He then continued the slow and deliberate hand movement along the
length of his shaft, stopping to massage the head each time he reached it.
Knowing he would soon be needing it I went to the washroom and got some
lubricant which he accepted with a smile spreading a little on each hand,
rubbing them together and resuming his slow methodic masturbation
technique. At times he would reach down and fondle his balls with the other
hand.  All the while he kept looking at Trish's nude photos.
   Finally he looked at Trish who had shot at least 200 frames by now and
said it would be great if she stripped for the grand finale.  She paused
for a second then thought what the hell he'll be watching her have sex
pretty soon anyway.  Handing me the camera she stood right in front of Jack
who had turned to see her and began slowly undoing her blouse.  Trish has a
lovely figure with pert 34B breasts and beautiful legs that end up at a
nice shapely ass.  She has all the properties of the perfect girl next door
to me.  Jack's gaze was locked on her as she took off the blouse to reveal
her braless breasts with firm globes and erect nipples.  I quickly started
shooting in movie mode so I wouldn't miss any of the action.  Undoing her
belt and slacks she slid down her pants and I shot over her as she bent
down to reveal Jack stroking his meat.  She stood and was now only wearing
tight french cut panties that were clearly sopping wet from her excitement.
Hooking her thumbs at the waistband she slid the panties down to the floor
then stood up to expose her perfectly shaven pussy.  Jack was now starting
to get close as Trish ventured closer and opening her legs she started
rubbing her wet pussy and clit with her right hand while her left hand
moved from breast to breast tweaking the erect nipples and massaging her
beautiful tits.
   Jack let out a small groan and then a louder one as he stepped up the
pace of his pumping.  His face had a strained expression as his eyes
grabbed one last look up and down Trish's body before he erupted.  His cum
shot up in the air, one thread shooting over his head while most of it
landed on his chest and face.  Stream after stream of thick white cum
landed on him and the chair until completely spent he slumped down into the
chair.  Holding up his cum filled hand he put it to his mouth and took a
taste all of which I was delighted to catch on video.  He looked at Trish
and asked if she was satisfied and she nodded yes with glassy eyes that
were filled with sexual charge.
   I asked Jack if he wanted to wash up before we continued and he
accepted. While he was gone I asked Trish if she was still game and all I
got was a kind of deep whispery uh-huh that I easily took as a yes.  Where
would you like to do it I asked and pointing to the bedroom she walked down
the hall into our room saying she'd call us when she was ready.  I had
never seen her worked up like this.  I just hoped I had enough stamina to
quench her thirst because I was sure there would be a willing backup in
Jack and I wasn't sure if I would be comfortable with that at all.
   Soon Jack came back with a towel around his waste.  I told him that she
was getting ready and would call us in.  Jack looked at me and said he had
never experienced an orgasm like that, the whole erotic scene had been so
overwhelming that his head was spinning and he thought his dick would
explode when he came.  Finally we heard the call from the room and went in
to see Trish lying on the bed wearing a sheer, transparent black cammi and
nothing else.  One look at Jack and she sat up, grabbed his towel away
exposing his impressive semi erect cock, I was jealous.  She lay back on
the bed patting her hand beside her as a gesture for me to join her.  As I
lay down beside her we began to kiss passionately.  That half crazed look
was still in her eyes.  Jack was hovering around taking pictures from all
angles and getting used to the camera.  My hands roamed from breast to
breast as the kissing became more and more intense.  Trish began undoing my
shirt and pants as I undid the tie to her cammi folding back the sheer
material to expose the length of her right side.  I sat up to take off my
shirt and slide the rest of my clothes off.  Lying back down beside Trish
we continued kissing as she fondled my shaft and I squeezed her butt cheek.
   I knew that Trish needed some immediate release so I moved downward,
sucking on her nipples as I passed.  I licked her belly and stuck my tongue
in her belly button that got a giggle out of her.  Then I moved in for the
kill.  Reaching her perfect shaved pussy I spread her legs open a little
more to give Jack a perfect view.  Her lips were swollen open and her
juices ran down into the crack of her ass.  I started circling her inner
lips with my finger stopping for a lot of extra attention at her clit every
time I reached it.  Trish's moans became louder and more frequent as I
leaned in and started to suck on her clit and tease it with my tongue.  She
was really enjoying the increased activity when I slipped two fingers into
her pussy and feeling up and behind her pelvic mound began to rub her soft
spongy g-spot.  Trish exploded in orgasm raising her hips off the bed and
uttering deep throaty sounds like I'd never heard before.
   Pushing my head away from her now too sensitive clit, I continued to rub
her g-spot as her hips moved along to the motion of my fingers.  Get that
cock up here she ordered as we moved into a 69 position on our sides.  I
was almost unaware of the clicking of the camera as she took my cock in her
mouth and began swirling her tongue around the head furiously.  I continued
finger fucking her while I caressed the little rosebud in her ass with the
other hand.  She normally didn't care for my touching her ass that way but
tonight she seemed to be enjoying it so gathering up the pussy juices on my
finger I took a chance pressing my finger in to the first knuckle.  Again
that met with the desired effect as she clearly pushed back against my
finger with her ass.  I was praying that Jack was getting all this because
I wasn't sure it would happen again and I wanted to have something to
remember it by.  Taking her hint I slowly pushed my finger in to the second
knuckle swirling it around slowly causing her start moaning almost like a
whimper as she continued to pump my cock in an out of her mouth.  Jack came
in for a super close up of my finger fucking action.  Moving the camera
aside he stuck his nose up close to her pussy and took a long deep sniff. I
pulled my fingers out and whispered to him if he wanted a taste.  I didn't
have to ask twice as he leaned in and took several tastes with his tongue
and sucked with his mouth.  Trish pulled her head back and asked what the
hell was going on down there.  Jack pulled away quickly apologizing that he
just had to have a little smell and taste of her gorgeous pussy.  Trish
didn't say anything but just continued with her blowjob.
   Now I've always envied men who could have multiple orgasms in a session
but I'm just not one of them.  It takes at least an hour for me to get
erect again after I cum and Trish's excellent blowjob was getting me close
to the edge.  I pulled away and asked her to get up and ride my cock. 
Without blinking an eye she was on top of me riding slow and sweet.  Jack
seemed to be everywhere.  First he was laying between my legs getting
close-ups of my dick sliding in and out of her as she rocked then he lay
down beside me shooting up at Trish then getting some great shots of my
penetration from the front.  Trish began to moan again and I new she was
close to another orgasm.  We continued on for another five or ten minutes
when I began to feel the unmistakable spasms of her orgasm.  That was all I
needed to send me over the top and I climaxed seconds after her.  She just
fell forward on me as we hugged and laughed softly.
   "That was so intense" I whispered to her as she nodded in response.
   After a few more minutes Trish rolled off me and put her cammi back on.
I looked at Jack and asked him if he had a good time and he nodded
enthusiastically.  Trish walked over and asked just what had gone on down
at her pussy earlier.  It was kind of exciting just to hear her ask the
question.  Jack was again embarrassed to answer that he just couldn't
resist and I said it was more my fault for inviting him.  Reaching over and
grabbing Jack's cock in her hand she admitted that some things can be a
little irresistible.  We all smiled as she continued to stroke him for a
minute or two and then bent over and gave the head of his cock a little
lick then a kiss.  Those are some of my most treasured shots of that
evening.
   Standing at the door we all shared a brief group hug.  Jack asked when I
would be in town next and I told him in about a month.  Good he whispered,
there's someone I'd like you to meet.  Trish rolled her eyes and gave him
another kiss before he walked out the door to the waiting cab.

With a little help from my friend (MMF, mast, exhib, voy)
