I'd never done anything as dirty as this in my life. I've been with guys, yeah, and even experimented with a girl when I was in high school. I liked doing stuff with people, always had a good time, and I'd made sure I was with people that weren't assholes or that would go talking to others about what we were doing.

But a couple of days ago, I did something I know I should not have done, and I feel guilty as hell about doing, but I still think about it, and yeah, I might be gross as fuck, but I want to do it again. I was in my bedroom, my mom had gone to work (she works at night), and my step dad was downstairs in the living room. It was probably about 1 in the morning. I wasn't expecting him to still be up, because he usually leaves the house about 7am for work. I went down the stairs, and I stopped in the hallway, when I heard him. I wasn't sure what was going on. But I looked across the living room, and I could see him at his computer. He had some music on, and the lights were off, except the one over his computer. And I'm watching him in his chair, he's sitting back, obviously watching something, and then I realize holy shit. He's masturbating. I stood there, and I realize I'm watching my step dad jerk it. And a few minutes later, I hear him grunt, and I see him blowing his wad into something. I'm not sure if it was a napkin, or a paper towel or dish towel or something. But like 2 minutes later, he reaches down, and he grabs something, and then I see him wipe up. And then he pulls his shorts up. Stands up. And he looks across the room. He stutters, and can't barely speak, and realizes I've seen him. He sees me.

He knew I'd seen him. He got all embarrassed, and I just kinda laughed and said hope you feel better. He just stares at me, and says oh shit Emily. I just laughed and said hey, everyone has their needs. Whatever it takes. And he looks at me and says you have needs too? I laughed and said well sure. Who doesn't. And I couldn't believe it when he says how about you take care of those needs and let me watch? I laughed. And said you're shitting me? He just says nah. I'm always perverted and dirty. Figure it couldn't hurt to ask. I just kinda looked at him. And realizing he wasn't kidding. I'd never thought about him like that, but I just said well sure. How about now? I think he was gonna shit. He'd just cum. But I think he was gonna shit too. I laughed and said not expecting that huh? How about you put on whatever you were getting off too. Must have been good. He got all uncomfortable, and said no. I'll find something. I just said nope. I wanna see what you had. And he says well, don't say I didn't warn you. It's kinda dirty. I said good. It must have worked to watch you blow your load. And he laughed and said well thanks for that.

When he put it on, I almost freaked. It was a dude about 30 or something, with a girl about 12 or 13. I looked at him and said kiddie porn? He just said no. Just one. You know she's gotta be 18 or 19. But she's made up to look real young. I looked at him and said not judging. But don't get busted. Just saying. I know a girl's body, cuz I'm a girl, and she's only like 12 or 13. But hey, that's cool. And he says well uh yeah, he's gonna fuck her. I looked at him and said no shit? He just kinda shrugged. I'd never seen anything like that. So I said well I wanna see it. I'm staring at this girl, just like a little patch of pussy hair when I was her age, small boobs, real small nipples, and yeah, this guy was older, has a condom, and he's putting it on his hard dick, and he's gonna fuck her. I knew it.

I'm watching my step dad, and watching the video too, and when they start getting into it, I pulled my shorts down, and started fingering myself. I hear my step dad go holy fuck. That's hot. I just laughed and looked at him. And he's staring right at me. Felt kinda weird at first, but I dunno, I just started getting turned on. And he says God. You're so fucking hot. I looked at him and kinda laughed. And I realized he was serious. At first, it was kind of creepy, but I don't know why, it just changed the hornier I was getting. I was almost ready to orgasm, and finally got there, and felt it. I came like 3 times fingering myself while this guy was fingering the girl, and then doing oral on her. It was really fucking amazing. And when he's going at it, I came again. I finally was tiring out, and just sat there with my naked ass on my step dad's computer chair. And I said to him how was that? He was looking at me, and he finally said God. You're fucking amazing. That was beyond awesome.

I'd never done anything like this before. Nothing. I just sat there leaning back, and said "would you have sex with me?" He just about fell off the couch. He said "excuse me?" and I just looked at him and said "sleep with me. I mean, like right now. It's just us in the house. Right now". He just stared at me. And I said "Sorry. I couldn't help it. I shouldn't have said that". He stood up. I looked, and his dick was fucking huge in his shorts. He'd already gotten hard again after cumming earlier.

I stood up, and he pushed into me, and started kissing me. I'd never thought anything like that. We were kissing intensely for a long time. He took my shirt and bra off, and I felt weird standing there naked in front of my step dad. He kind of leads me back to the living room, and we're standing there. He looks at me, and says to me, did you mean it? I said yeah. I was scared as hell, freaked a bit, not thinking he'd actually do it, but I said to him again yeah. I wanna sleep with you.

He took me right there on the floor. Went all over my naked body, kissing, licking, sucking on my boobs, fingering me (he made me cum twice more), and getting me all worked up. He kind of got on his knees, and pulled his shorts and boxers off, and his dick was standing straight out. I just looked at him and said no. Have sex with me right now.

He looked at me, and he just slid inside me. It felt huge. My whole body started shaking. He pushed harder. Got it halfway up, and then pushed harder, and shoved it inside me. It was huge. He was laying there inside me, and started pushing. He started kissing me, and was pushing in and out. And kept saying things, talking while she was doing it. Then I felt it. I came again. I grabbed ahold of his back, an started going off. He kept going and going, and like 5 minutes later, I was watching his face, and he said I'm gonna come. What do you want me to do? I'd never let a guy go off in me. I'm on birth control, but I'd never let a guy do it. Until I told him just go off. It's fine.

He exploded. I was watching his face, he was groaning, making all sorts of noises, pushing deep in me, pulling out, and pushing harder. It was amazing. When he finished, he was kind of on his knees and his elbows, staring at me. And said holy jesus. I just laughed and said yeah. That's what it felt like.

He kind of awkwardly got off me, and I was staring at his soft dick. I sat up, and felt his cum dripping out of me. It was all messy. He handed me a shirt, and I put it between my legs, as I took my pajamas into the bathroom. Standing there looking in the mirror, I realized I'd just fucked my step dad.

When I went back out, he was already dressed. Kind of sitting there. And said maybe we should talk. I said yeah. We talked for like a half hour about it. And we said it was amazing, and really great. I asked him if he'd do it again. He was really surprised, but said hell yes, he'd do it again in a heartbeat. He asked me. I said yes. As long as nobody knew.

We haven't done it again yet. But I want to.
