Gwen SeXStoRY

 I married her thinking we wanted the same things, She was looking for a meal ticket, babysitter, and credit cards to support her d**g habit (Valium and whatever else she could get over the Internet.  She had a sweet little blond daughter named Gwen with a beautiful smile, a little  chubby with baby fat, just starting to develop boobs.   Her mom was wasted most of the time and a full time bitch.  Gwen and I got very close out of self defense and out of genuine fondness.  I focused on Gwen and my work for the next few years.  My  job took us to another state, halfway across the country.   Once we had moved and settled in, her mother went into a depression that lasted  for the next several years.  So it was left to me to deal with the adolescent  girl and all her normal puberty issues, moving away from the only place she had  ever lived, and all the baggage that goes with it.  My new job was very  stressful.  Dealing with the heavilyy medicated zombie mother, and Gwen was  almost more than I could handle.  Work and Gwen became my priorities.  Once we  settled in, tho, she flourished in the new school. We were living in an upscale  suburb, she met lots of nice k**s, and then there were the riding lessons.     Gwen and I started; growing closer.  I was the man in her life that had never  been there, and she was the female who was happy to see me, affectionate and  flirty.  It gave my ego a boost to have this pretty, now 18 year old hugging on  me and being excited to see me.  I would get home from work, and take her to the  stables, wait around watching her ride, and then we would go home, deal with  dinner, homework, and whatever, basically interacting with her mother when she  would bother to be awake and out of bed.   Gwen would go with me to buy groceries, run errands, all the usual stuff a wife  would be doing with her husband.  She would hang on me in stores, come up behind  me, wrap her arms around me, and mold herself to my back and tell me she loved  me.  I gradually started to respond.     It started one evening, I was working in my study, sitting in a recliner with  the keyboard on my lap, and she came in and asked if I could talk to her for a  while.   "Sure, sweety, what do you need?"  I put the keyboard away and gave her my full  attention.  I noticed that she was ready to go to bed, wearing one of my old  white tshirts that had been washed a hundred times and was very soft.  It came  down to her mid thighs, and was fairly sheer.  She wasn't wearing anything under  it, that I could tell. Her breasts had grown quite a bit, into an a or small b  cup.  Her nipples were standing out.   She sat down on the arm of the recliner, and sort of slid across into my lap,  wiggling her slightly plump ass into my crotch, which was starting to respond  and demand attention. (it had been quite a while since her mom had shut down on  me, at least a year)  Gwen wrapped her arm around my neck and laid her head  against my shoulder.  She reached out wiht her other hand and took my free hand  and held it.   She looked at me and smiled and said, "you know, I really do love you", then she  gave me a soft kiss on the lips.  Nothing lingering or erotic, just a short  sweet little girl kiss.  "I know thing are not good with you and mom,  I don't  know how to help".  I just smiled "Sweety, just knowing you love me helps more  than you could imaging", and I kissed her on the forehead.  She smiled and  wiggled her sexy round ass down into my lap again, then took my hand and laid it  on her bare leg and slid it up under her tshirt to her hip, pullin up the shirt  quite a bit, showing me 2 things. She was a natural, real blond, and wasn't  wearing any panties.   Gwen looked me in the eyes and kissed me again. Definitely not a little girl  kiss.  She probed my lips with her tongue, until I responded and staqrted  kissing her back. She wrapped her other arm around the other side of my neck and  became much more passionate.  My hand was free to start caressing her bare ass,  and squeezing it.  She moaned into my mouth.  I slid my hand up further and put  my hand on her breast, rubbing it softly and toying with her hard large nipple.   She started to move her hips, thrusting slowly.   The alarm bells started going off in my head and I knew I had to stop and get it  under control quickly.  I broke off the kiss and pulled my face back from hers.   There was so much love in her eyes, that was starting to glaze over into lust  and she bit on her lower lip.  It was all I could to to tell her "We have to  stop baby, before this goes any further". I pulled my hand back down out from  under the shirt, lingering for a few moments on her ass, and then pulled her  shirt down.  She looked back at me and tears started to form.  I understood.   "No, no, no, it is not because I don't want you, or I don't think you are  pretty, You are beautiful, but you are like my daughter, and this can't happen.   She blinked and said "ok, I better get to bed, I have school tomorrow"  She  didn't get up for a few minutes, we just continued looking at each other until I  said, "you need to go"..  She got up and walked to the door and turned around to  look at me. She pulled the tshirt up over her head and smiled at me, turned and  walked out the door toward her room, naked.     I spent the next few minutes getting my breathing under control.  I couldn't  stand it any more and yanked my pants down, closed my eyes and started pulling  on my cock.   I closed my eyes, remembering her touch and taste and exploded in  a huge burst of cum in about 2 minutes, all over stomach.  When I opened my  eyes, she was standing in the doorway again, naked, giggling.  She threw me the  shirt and said, "you made a mess", blew me a kiss and ran off to bed.   I tried to keep my distance from Gwen for the next few days, knowing that we  could not let that happen again, no matter how it felt.  Gwen was busy with  school stuff and I focused on work and tried to convince myself that it never  really happened.     Then Gwen started watching me, and making sure that I noticed her, touching her  breasts, rubbing her crotch, flashing me... basically driving me crazy.  I kept  as much physical distance between us as I could, trying to not get into a  situation where I would be in close contact with her.  She kept teasing me, and  wearing me down.  She cornered me in the kitchen, pressed up against me, and  wrapped her arms around my neck.  She looked up at me "What's wrong? Don't you  think I am pretty?"  her eyes had tears in them.     "No baby, that is not the problem, I think you are beautiful, and the best thing  in my life, but what I did was wrong"  I put my arms around her and hugged her,  stroking her beautiful blond hair.  "I am your step-dad, you are as much my  daughter as if I was really your father,  I love you so much, and I do not want  to ever hurt you"   She looked up at me again, "I love you too, and I want you to be happy, and I  know you are not, that mama makes you sad"   I smiled at her, "knowing that you love me makes me very happy, now scoot, you  have homework to do"  I thought that it was settled.   As she walked away, she turned back and raised up her tshirt and bra, wiggled  her boobs and giggle "But I know what you want" pulled her shirt down and ran  out of the kitchen toward her room.  I broke into a cold sweat.   Later that night, I was working in my study again, and she walked past on her  way to the bathroom and said "I am going to take a shower and go to bed"   "G'nite baby" I told her. and thought nothing about it.  A while later I got up  to go to bed and when I did, her bathroom light was still on.  I went to turn  off the light, and there she was, still in the bathroom, wearing a very short  little nightgown I had gotten her mother.. it was sheer enough to read through  and did not cover her butt.  She was leaning over the sink with her back to the  door.  She saw me in the mirror.   I stood in the doorway, completely paralyzed, transfixed by the site of this  beautiful girl wearing next to nothing. She turned to face me and asked "What do  you think?  Mama isn't going to wear it for you, and you deserve to see it.  It  fits me pretty goot."   I could not even respond.  I felt like my eyes were going to fall out of my  head.  After a minute I shook my head and said "Baby girl, it looks better on  you than it ever would have on your mother"     She smiled at me.  not a little girl smile, but a very womanly, sexy smile and  ran her hands down over her breasts to the bottom of the gown.  Her nipples  stood out hard and stiff.  "come closer" she said.   I walked into the bathroom and sank to my knees in front of her.  her nipples  were right at eye level.  I reached up with one hand and cautiously touched one  of her breasts, palming it, softly squeezing it and at the same time took the  other nipple in my mouth, through the flimsy gown and gently bit down.  she  gasped, and pulled my head closer in to her chest.  I continued to tease her  nipples, pinching and pulling one, and nibbling on the other with my lips,  sucking on it, and giving it little gentle bites with my teeth, switching back  and forth between them.  She began to grind and thrust her pussy against me.  I  slid my hands down her sides and started kissing my way down her stomach, until  i reached the bottom of the gown.  I looked up at her, and she looked down into  my eyes, and pulled up the gown. I pushed her up to sit on the edge of the  vanity, and started kissing her thighs, she pulled her feet up onto my shoulders  and I started kissing and licking her sweet little pussy,  Slow soft licks,  flickering on her clit, then back up and down the length of her labia.  Her  breathing became quicker and more shallow and she pulled my head into her pussy  with both hands.  I kept licking until her clit was standing out pretty stiff,  and started to very gently suck on the clit.  It was difficult to keep my mouth  and tongue where they needed to be, she was thrusting and wiggling and grinding  against my face.  Finally she started saying "ohGod, ohGod, ohGof faster and  faster until she started cumming so hard she nearly fell off the vanity. When  she finally calmed down enough to tell me to stop, I kissed my way back up her  tummy to her boobs and then to her mouth, where she tried to suck the kisses out  of my mouth.  Once she settled, she wrapped her legs around me and continued to  grind and kiss.     She reached down and started rubbing my cock through my pants and pulling at my  belt.   more later...
