My GFs sister(Current Rating 60/100, based on 42 votes)
It was a nice warm and sunny day in early July when I thought I would surprise my girlfriend with a visit. I knocked on the door and there was no answer. I noticed, however, that the door was slightly open so I let myself in. I called her name a couple of times, and still nothing. I went up to her room, again, nothing. So I thought I would check one last place, the swimming pool in the backyard. Boy, was I surprised! My girlfriend wasn't back there, but her hot 18 year old sister was. And she was swimming topless!!! I turned away, embarrassed, and asked "Denise, where's Laura?" She replied "she brought my mom to the doctor for her check up, she's probably going to be gone most of the afternoon. Is there a reason you're not looking at me?" As I said, she's hot, and 18, and I'm 25. Sure, I'd fuck her brains out if I could, but I can't lead on like that, after all she I'd my girlfriends sister. "Come on, jump in. The water is beautiful." "I can't" I stammered, "I don't have my trunks with me."
"That's fine" she said, "I won't tell." Oh my God, was this really happening? By this time, I was rock hard, but still kind of nervous. I decided, "what the hell" and jumped in. The water was a little cold, but the sight of her tits was enough to offset the "shrinkage" factor. I swam over to her and she planted a long passionate kiss on me and started rubbing her fingers through my chest hair. "I've wanted you ever since I caught you and my sister having sex a couple of months ago." I started running my hands up and down her gorgeous body and realized she was completely naked in the water. I started to finger her bald pussy and suck on her nipples. She was so wet, and not just from the pool. I was finger fucking her when I realized she started stroking my cock. "Oh my God" she moaned, "put your cock in me, I promise not to tell!"
I entered her slowly, as I wasn't sure if she was a virgin or not. It felt so good having my dick in her hot, wet snatch. I kept thrusting myself back and forth, and she kept begging for more. I was sucking on her tits and fucking her hard. "Oh fuck, I'm gonna cum" I yelled. "Give it to me" she begged, "cum in my pussy!" As soon as she said that, I spewed hot jizz into her thirsty cunt. "Oh God that was great" I panted. "What do say we dry off" she said "and I'll give you a blow job you will never forget." I guess she wasn't a virgin after all. Now if I can only get her and her sister at the same time, that would be fucking awesome!!!
