I am a 40 year old Male that just recently moved in with my Girlfriend of 6 months. Well My girlfriend is a nurse and works from 8 pm to 8 am and has a 17 year old daughter (Melanie) who is Voluptuous with bra size 40 DD's and walks around the house without a bra and in some real tight boy shorts I have noticed that she gets too comfortable and changes into these real skimpy outfits as soon as her mother leaves to work. I was watching Basketball the other night when she walked into the living room with just her nice lacy panties on, asking me who was winning. Well last night I was in my recliner and she was wearing no panties and some short loose shorts and sat on the couch across from me and flashed me her trimmed pussy while she sat Indian style. I had a huge boner and stood up to get me a beer, she noticed my bulge in my shorts and kept staring at it while I walked to the kitchen. I came back to the living room and she was on my recliner, we jokingly played to fight for my recliner and she gave in and got off my chair and when I sat down she followed and sat on my lap, knowing that I have the huge erection she purposely sat on my bulge and looked at me and asked if it was ok. I said ok just this one time. She leaned her back against my chest and gave me a beautiful view of her nice young perky tits. I couldn't function right I took a big drink from my beer as she positioned herself where my dick was right in between her ass cheeks. She would move a little side to side every few seconds she then put the back of her head on my right shoulder with her eyes closed she moaned a bit and turned to me with this sexy fucking erotic look. We both knew what she was doing she bit her lip and asked should I get off? I told her only if she was done, if not to go ahead and get her grind on and Enjoy the ride. She told me that she wasn't a virgin anymore and had sex a few months ago and has had the urge for more sex since then I put my beer down and grabbed her nice big tits with both hands as she dry humped me reverse cowgirl style. She was so into humping my dick that i pulled her shirt up and was inching her big nipples. I slipped my hand under her loose shorts through the side and felt this wet creamy feelings all over my hand, her shorts were drenched in her juices. I slipped my finger in her and rubbed her clit she moaned louder and louder and was climaxing big her leg was shaking her body was quivering and she let out this relieving yelp and exhaled and just relaxed on my chest for a bit. She got up and walked to her room as if nothing happened. I was in disbelief on what just happened and sat for a few minutes and said AH Fuck it. I went to her room as she was laying in her bed I told her my turn. I peeled her shorts off and ate that sweet lil tight pussy of hers and slurped all of her creamy pussy fluids. She begged for me to fuck her but I did not want to. She then said "I won't mention any of this but you have to fuck me" I had no choice but to feed her my rock hard dick. She was the tightest thing I have ever had since my high school days. I rammed her nice and deep she then rode me like like a cowgirl should I sucked on her huge tittys and right before I nutted I pulled out and shot my load on her tits. She followed it with a clean up with her fingers and tongue, she is a kinky little bitch but Could get me in trouble, she vowed to secrecy but she just wants to be satisfied while mommys away.
