To explain how it is now, I need to take you back a couple of years to then.
Good O'l Dad got to missing my mother after she left this world.  He was sad and
lonely, and I was angry that my life would not be like I thought everyone else's
would be.  Over time, Dad gradually started putting down the Playboys and
started to spend a little time out of the house meeting real women.  That was
great, because I could spend time with his magazines at a time when I was
getting as curious as hell about the opposite sex.

Terry, a thirty-two year old secretary, whom my dad met on a sales call, moved
in with us when I was fifteen.  There was the promise of marriage and she acted
like our place was hers.  She started to change our routines, how we had the
house arranged, and accidentally broke or made things mysteriously disappear
that reminded me of my real mom.  Eventually, the only pictures of my mom were
in my room.  Dad's Playboys got fewer and far between.  I started hoarding them
when I thought he was probably through looking, and before Terry could get her
hands on them.  He probably thought it was Terry making them disappear.  And,
then there were none.

Terry was a sexy lady, there was no taking that away from her.  She was a good
fifteen years younger than my dad, and she had fun teasing both of us around the
house.  First it was no bras, then tight fitting clothes, then thinner and
thinner material so you'd know that there was something great to stare at, but
you'd really have to stare too long for polite company to make out what you were
looking at completely.  This was fine for dad, because eventually, when she
willed it, he could get his relief from her.  Me however, she delighted in
tormenting, knowing I'd have difficulty in getting relief. 

She started nosing around and dropping in on me without knocking to insure that
I would not have a free reign of my time alone.  She'd even come in while I was
showering to hang new towels, or to pick up my clothes.  It wasn't like she was
domestic or anything, because if I wanted anything clean, I ended up washing it
myself.  Getting a chance to masturbate to dad's old magazines grew to be more
and more of a challenge, though.

One night, after we watched an R rated video in the living room together, with
me trying to ignore Terry kittening up to my dad during the show, especially
after the skin scenes, I had to really tap the prostrate.  I figured I'd have
the coast clear, with Terry and my dad doing it in their room.  I spread out my
absolute favorites around me on the bed.  This was going to be a super drainer.
It was as if Terry had her ear to the door.  Right as I was going to let myself
fly, in walked Terry under the guise of asking me to join them for a snack
before going to bed.  She was in a see through nightie, I was in shock, and I
was too far gone to stop what I was doing.  I shifted my attention from the
potential embarrassment facing me, and stared at her features through the gown
and shot messy ropes across Miss July. 

I was dumbfounded, and tried to cover up with Miss August and February as Terry
approached.  "What's the meaning of this disgusting display, Young Man!"  She
said standing next to me with her fists on her hips.  When she started picking
up magazines and looking at them.  I had no leverage to complain and demand them
back.  Then she grabbed August and February.  I tried to hold on, but my
developing manhood was momentarily on display until I could return my hands to
its defense.  I had to sit there like a boob on a log as Terry took up each of
my favorites and started ripping the pictures and throwing the magazines in the
basket as she went along.  "There, that will teach you to bring that filthy
trash into this house."  She said, picking up the basket, throwing clothes at
me, and leaving while telling me what a pervert I was.

Fortunately, I still had a second and third string collection, but she destroyed
my whole first string super drainer collection.  I was sad and I was furious,
not to mention humiliated and embarrassed.  I knew she would bring this up with
dad, so I snuck out to see if I could listen in to their conversation.  "He
needs to relieve the sexual tension like all guys do."  Dad defended.

Terry, in my opinion, had little to argue against my doing it, except that I may
never grow up having a healthy relationship with a girl if I continued to make
love to pictures in a magazine unable to respond.

"The only woman in this house is you, and you are starting to walk around half
naked all of the time.  With a face and body like yours, it's a wonder he
doesn't spank the monkey more often."  Dad said.

Yeah, Dad.

Terry must have smiled at the imbedded compliment, because she said, "Come here
you."  And that was the last intelligible conversation I could hear.

I went back to my room fuming.  "I'm going to pay that bitch back for this.  She
can't get away with destroying my property like that, well, my dad's property."

Over the next month, Terry moved on to flashing me.  I almost didn't want to be
in the house alone with her.  She was teasing me unmercifully when my dad wasn't
around.  It was embarrassing the way she would look at my crotch like a
scorecard to see how she was doing in her game.  She'd move around the breakfast
table with just a short silk robe clinging to her bumps and curves.  When she
was loading the dishwasher, she would let the robe hang open, so I'd think I was
catching glimpses of her naked body, but that was my mind filling in the blanks
I'm sure.  What I was able to see was the hem climb up the back of her legs, as
she bent forward, to within inches of their junction.

Terry was having so much fun at teasing me and interfering with my attempts at
giving myself relief in private, that it was making her hot.  She felt
particularly victorious when she found the balance of my magazine stash and
removed them from the house.  She was getting so full of herself and hot at
home, that when I was in school, she stayed in a tease mode for others.  This
included delivery people, the unemployed men in our neighborhood when washing
her car outside or on walks, and the clerks and old men at the grocery store.
It made her horny all day and she looked to Dad to get relief at night.  She
liked teasing so much, that she became over sexed, more than my dad could
handle, and she turned it into full-blown seduction.

It was during just such an incident that the tables turned.  We were let out of
school early due to a student  crashing his car at lunch killing one passenger
while injuring himself and two others.  It was on the local news, but Terry
wasn't paying any attention to the real world, she was bonking the owner of the
dog who was tied up out front, whom she met at the park.  I wish you could have
seen her face when I walked in on her.  Like me, she was ready to be knocked
over the edge with a feather.  She looked up from the kitchen table at me
staring at her in disbelief, while the unaware stranger was banging her crotch
with animalistic rutting.  She didn't have it in her to slap him into stopping,
not until she crossed her threshold at least, despite the display she would make
for me.  And over the top she went, screaming, flailing, and finally weeping as
she waited humiliated for the stranger grunting his seed into her cunt.

"Oh my god."  He said when he discovered me standing there, and hurried out
before he was even finished redoing his pants.

Terry rolled off the table, sat huddled in a chair, and wept into her hands
totally humiliated by what she had done and had now been discovered by me.   I
was angry for my dad's sake, but I was about to explode with glee at my luck.
My dad's fuckable babe was brought down from her untouchable thrown, and was now
at my mercy.  While she had been acting like my dad's wife, and treating me like
a stepson, so to speak, she was not yet married to him.  My dad made it possible
for her to leave her job and be a lady of leisure at home.  If she were to be
thrown out now, she would have to say goodbye to a great guy, my dad, access to
enough money to get or do anything she would want, and have to go back to making
her way in life starting all over again. 

I handed her the only piece of clothing I could see in the room, a small
stretchy pullover sundress.  I didn't say a word.  I quietly walked out of the
room to go upstairs.  In the hall I jumped and punched the air several times,
screaming a cheer loudly inside of my head in celebration.  Once in my room, I
stared and smiled at myself in the mirror.  Then I took down my pants and
started a celebratory stroking of my wiener, closing my eyes to better remember
the sight of Terry lying naked on the kitchen table being fucked by a stranger.

Then she did it again.  She opened the door to my room, only this time she
knocked as she stood looking at my bare backside.  "May I talk to you?"  She
asked submissively.

There I was feeling embarrassed again, my pants down to my ankles, my cock in my
hand, and my maybe to be stepmom wanting to talk to me.  "No wait," I thought,
"I don't need to feel embarrassed.  She is the one to feel embarrassed."  I
turned leaning back against my bureau with my hands at my sides on the edge, one
ankle over the other, and my cock at 10:00.  It might have gone down in any
other circumstance, but the little, lightweight sundress that Terry was wearing
was like Viagra for teens.  "Yes?"  I said with a new found confidence.

"Please don't tell your father.  I won't ever do it again, and I'll doing
anything to you ask to make the incident go away."  She said pleadingly.

"Anything?"  I asked rather cocky.

"Yes" she nodded, looking down to the right.

"Take off that dress then."

"What?"  She said stalling.

"You heard me.  You said anything."

To which she switched into a kitten mode and slowly wiggled out of the dress.

"Now, come over here and kiss it."  I directed, referring to my throbbing pole.

"This isn't right, you know."  She said, as if she had all of a sudden gotten
religion.

"I'm waiting."  I said, not budging from my intent to reek revenge on stepmommy
dearest.

She closed her eyes, bent forward holding her breasts with one arm and
supporting herself with a hand on her thigh with the other and kissed the
underside of my cock gently.  It was an exquisite feeling, but too fleeting.
"Lick it."  I ordered.

She looked at me pained, but proceeded to lick up the length of my cock. 

"Don't stop," I said, "and do the balls too."

She kept licking.  I spread my legs.  Her breath on my balls was almost as
stimulating as the actual touch of her tongue. 

"Put it in your mouth."

She groaned a complaining groan, but proceeded to do as directed.  As her mouth
slid down over the corona, I reflexively squeezed out tiny batches of air due to
the intensity of this only dreamed of sensation coming to life.  I almost
couldn't take it, my virgin cock inside of a woman for the first time.  She just
held it in her mouth and moved her tongue around a bit.  I was reflexively
moving to pull my cock out and away from the intense pleasure, then pushed back
in to recapture it.  Terry crouched down and placed her hands on my hips to keep
me from lounging forward uncontrolled. 

"Suck it.  Do something."  I ordered.  "Don't just leave it there like this."

She started to move her head up and down on it and sucked to create a delicious
friction.  Just as I was about to cum, she removed her mouth and started to lick
again, probably to breathe a little easier. 

"Don't.  Stop it.  Suck it again.  Don't stop sucking it."  I said panicked that
she would do something to interrupt my inaugural coming inside a woman.

I started to buck and breathe erratically.  I knew I was cumming, and I guessed
she knew I was cumming, so I put both of my hands on the back of her head and
forced her to stay on me while I relieved the pressure into her unwilling mouth.
She was no longer sucking.  She was trying to avoid swallowing the ejaculate.
She grimaced as I plunged in and out of her lips in and out of my pearl jam that
was oozing out the corners of her mouth.  When I couldn't take the sensation any
longer, I let her up.  She spit into some dirty clothes on the floor, coughed
and gagged for a moment. 

When she stood up holding her dress over her arm, she asked hopefully,  "Okay,
now we're square, right?"

"Right."  I responded sarcastically.
