I don't know what made me do it. I really don't. Stupidity. Idiocy. Crazy hormones for an older guy with a lame ass marriage, lousy sex life, and bad situation. I can't tell you. But one night, when one of my daughter's friends was spending the night, we were joking about some off the wall dirty shit (I'm always good at that), and she made a crack about fucking. I just laughed and said "you never know you might like it. Don't knock it until you try it". And she just kind of laughed it off.

About an hour later, I was downstairs, laying on the couch, reading a book on my tablet, and Sarah came downstairs. She looked at me and said "comfy" and I just cracked a joke like I always do, and said "well not as comfy as I'd be if you were on me". Without a word, she walks over, climbs up on the couch, and straddles me. I about pushed her off. I looked at her and said "whoah. Wait" and she laughed and said "don't knock it until you try it" and was getting off the couch. I don't know why I did it, but I grabbed her, and pulled her back. She fell on me. I kissed her. I mean, really fucking kissed her. She jerked back and said "holy shit dude." and I just laughed. She looked at me all serious and said "you're not kidding?" I just shrugged.

She's about 5'10 and about 175. She's got for a girl her age, a big set of tits, a bigger ass, and pretty good sized body. Bigger stomach, but not "fat" - just big boned. She pushed down. Hard. And damn if my dick didn't just spring. She looked and said "someone's hormones can't control themselves". I just kind of laughed and said "well yeah"

I honest to God never thought anything would come of it. But we're laying on the couch, she's looking up the stairs, and without a word, reaches up and pulls her shirt off. I'm looking at like a 38D bra size for a 16 year old girl. She had the biggest tits I'd ever seen for a girl her age. I just looked up the stairs, and started kissing her. Kept thinking that holy shit, someone is going to come down.

We ended up going at it for a couple of minutes. She got up off the couch. Kind of stands there, and pulls down her sweats and is standing there in her bra and underwear. I stood up and said "seriously?" she shows me a condom and says "yeah. I wasn't kidding. I'm really horny, and if we can keep this between us, well yeah. I'm serious"

We ended up naked, I'm not shitting you in probably 3 minutes. My dick was standing straight up, and I couldn't control it. I'd seen her in a bathing suit. She's a bigger girl, but I couldn't stop staring at her tits and her big round ass. Honest to God, I was so fucking horny I couldn't control it. We wound up on my living room floor. I ate her out for about 5 minutes, and swear to Jesus she came harder than almost any girl I'd ever fucked. She was laying there panting, on her back, her pussy hair completely soaked. I couldn't resist. I opened the condom package, unwrapped it down my dick, and as she was laying there, I entered her. It felt so goddamn tight. I heard her gasp. I went down inside her wet pussy, and was laying on her. I started kissing her softly, and then harder, pumping in and out, while sliding my tongue in her mouth. Not more than a couple of minutes later, I'm still going slowly, I heard her say "oh sweet Jesus, I'm going to come" and damn if she didn't.

I had my mouth on hers, and I pulled back long enough to say "oh God Sarah, I'm going to come". She was gasping, and she had her hands on my ass, and kept pulling me. I fucking blew. Seriously. It was intense. My whole body was shaking. I was pumping. I felt the cum squirt out of my dick into the condom, and kept going as I was thrusting inside her deep as I could go. Boom. Empty.

I just laid there. Looking at her and said "holy shit". We were panting. I kind of rolled sideways, and she moved. I saw her get up, and watched her walk across the living room to the bathroom. She came back a copule of minutes later, got dressed, I got dressed, and I took the condom and threw it in the toilet and flushed. We just kind of looked at each other and I said "well uh OK. Now what". She kind of laughed and said "seriously? I really want to do that again. Next time I come over. I'm so not kidding. You were absolutely amazing". I just smiled. Leaned over, kissed her on the cheek and said "thanks. The same goes to you"

Funny. She went upstairs, went to bed. And came down the next morning. We're sitting there, eating breakfast. My daughter goes into the other room for something. Sarah leans over and says to me "I'm all squishy down there. Thanks" I about spit my fucking cereal all over the table. My daughter comes back in and says "are you OK?" and Sarah is laughing. She says "Yeah. He's just choking. But I think he'll live"

Yeah. Thinking about fucking her? She's one of the biggest girls I've ever had sex with. But something about her big tits, and her nice big round ass. And that absolutely fucking amazing teenage pussy. I'm gonna go masturbate before bed.
