I'd read stories on here for months about guys doing the craziest dirtiest stuff, and I'd often fantasize about doing things that they write about. Now I don't know how much of this stuff is true, or how much is fantasy, but I can tell you, there have been multiple nights I've read these things, and masturbated, fantasizing about fucking my own 16 year old step daughter. I know it's dirty and fucked up, but she's an amazingly cute chick, she's got a dirty mouth, and I'm a mid 40's guy with hormones and a sex drive that my wife has no interest in keeping up, or doesn't even try. It sucks. So I get on here time and time again and masturbate, imagining it's me in some of those situations. I'd just been afraid to act on it, because I don't want that label, I don't want to get caught, and I don't want to fuck up my life.

I'm scared to admit what happened last night, but I guess as many times as I've been on here reading, it's not much different than what I've seen others talk about. I was on here last night, after my wife went to work on her 4 night a week overnight shift. My step daughter had taken her car, and gone to work at the mall. Telling me she'd be home about 930 or so. I had the house alone. So I'm reading here more, and got horny, and ended up masturbating again. Did my normal thing. And was on the couch watching a movie when my step daughter Sam came home. Asked her about her day at work, the crazy people she dealt with, and all that. She told me she'd gotten some dinner, but was hungry, wanted a snack, was going to get a shower, and asked if I wanted to hang out and watch a movie. I said yeah, only if she'd be done in less than 2 hours (that's her normal shower). She laughed and said yeah. So she goes in, I hear the music, I hear the shower, and I'm reading. Fantasizing, thinking about the lucky fuckers on here that write the dirty stories. She comes out about a half hour later. I laughed and said world record. She said yep, remember this day. And she comes around my computer desk. I'm in my chair, and she says what you reading or doing? I said just boring shit. She looks, and says oh. No porn huh? And laughs. I looked at her, and she's actually got a sad look on her face. So I laugh and said well I can always pull up some porn. She looks at me and says sure. Why don't you? I thought she was joking. I turn to look at her, and she's leaning in. Her wet hair is on my neck, and she's really close to me. So I just kissed her. I put my mouth to hers, and just kissed. She jerked back and looked at me in shock. I just stuttered, I'm sorry. Shit. That was so wrong. I should not have done that. She just looked at me. I knew I'd fucked up. She just stared at me. I said I'm sorry Sam. I didn't mean that. She looked at me and said are you sure? I said sure what? And she said are you sure you didn't want to do that? I was honest. I said I'm sure. I did want to do that. I meant it. I wanted to know what it felt like, not just a normal boring kiss goodnight. She stood there staring at me. And said would you do it again? My heart beat in my chest. I said why? She said because I want to know? I reached up, pulled her against me, felt her chest against my arms, and kissed her. We kissed for what felt like 5 minutes. When it was done, I was panting, breathing heavy, and her face was beet red, and she was just staring at it.

I said come on Sam. Say something. She finally did. She looked at me and said you don't just want that do you? I said no. I don't. And she said what do you want? I just looked at her. And she said I know what you want. It's kind of gross and weird and nasty. But it's not. What do you want? I finally said it. I told her I want to be with you. Completely. All the way. She looked at me, her face red, and said you want to sleep with me? I looked right her in the eyes, and said yes. She didn't say anything. I knew it was done. I said I'm sorry. It's wrong. And we shouldn't be talking this way. It's just not right. So let's forget this ever happened. OK? Let's just drop it. Sam stood there, and finally said to me what if I don't want to? I said don't want to what? And she said drop it? I said so if your mom finds out, I get busted, and it fucks up my life, and I'm going to have problems like I've never had. She stared at me. And said no. That's not what I meant. I'm not telling you that I'm going to talk to someone. I said then what? She didn't say anything for a second. And then says what if I want you to? I was stunned. I said want me to what? With you? She nodded. I said I wouldn't say no. I would not ever consider saying no. She stood there and after a couple of minutes, she said to me well, I would.

We ended up going upstairs about 5 minutes later. We ended up going into my bedroom. I know it's the bed my wife and I sleep on. But I didn't care. I was so horny and so desperately crazy to see if this would happen. And it did. It took awhile to get past the awkward stage. But after we did, I saw her undressed, her small little boobs, skinny legs, flat stomach, and her cute little teenage body. I felt a bit self conscious, because I'm not in the most perfect shape, have a really hairy chest, and I'm not by any means perfectly fit. But she didn't seem to care. We ended up making out on my bed, kissing, touching, and getting close. She was touching my cock for a little bit, let me finger her, and I convinced her to let me do oral on her. I went down on her for a long time, and I made her orgasm several times. When it was finally to where I knew we were going to cross that line, I stopped. I couldn't carry through when she told me she'd never had sex before. She told me that she'd had chances, but she'd never gone there because it didn't feel right. I finally told her I can't do it. I can't be your first. She said why? I told her. Friends would ask. Relatives, whatever, boyfriends, etc. And she said that's fine. I'll lie. I've made up my mind. If you will, well I'm OK.

I had to go into the bathroom and get a towel, just in case. I knew she was on the pill, because my wife and I had actually gotten her on it younger when she had horrible cramps and would miss school. And when we were on the bed, I was between her legs, staring at her blonde pubic hair, and staring into her pussy. I felt horrible, honestly, i won't lie, knowing what I was going to consider doing. And she said I'm sure. I know what I want you to do. If I didn't, I'd tell you.

It took me a long long time to finally break through. I told her I wouldn't orgasm inside her, not the first time, just in case, I didn't want to have anything happen God forbid, like that. It took me probably 20 minutes to finally break all the way through, and penetrate her. She'd cry out a little, I'd stop, she'd gasp, I'd stop, and I finally said to her Sam, I'm going to. It might hurt a little bit. She said she was ready. I laid there, watched it, and thrust my cock all the way hard inside her. It entered her deeply, I heard her cry out loudly, and I felt myself go all the way inside her. I laid there for a long time, moving slow. And at one point, I'd pulled out, and saw it was covered with blood. I felt dirty as shit, and nasty and perverted, but I couldn't help it. It was the most intense thing I'd ever done.

A few minutes later, i was moving slowly, and I felt her hands come around, and pull me against her. I was going to explode, and I told her that I had to pull out in case there was an accident. She said no. She felt really good with me doing what I was doing, and she wouldn't mind if I wanted to finish. It took me just a couple of minutes, being inside her, fully filling her, and I came. It shook my whole body. When we were finally done, I just laid there, leaned in, and she kissed me. Hard. She said how many girls can brag that their first time was that incredible? Well, I can. I just laughed and said well, it's not that easy. She said that's true.

We talked for a bit, and eventually got cleaned up. I felt awkward, dirty and gross for the longest time that evening. Until about 2 in the morning, she was getting ready to go to bed last night, and I went into her room to talk to her about it. We ended up doing it again. On her bed. This time we did even more, and I ended up finishing inside her again. When we were done, I just sat there on her bed talking to her. She told me don't worry. It's not like she's going to get me in trouble.

And as I was leaving, she said can I ask you something? I said yes. And she said would you do it? More? With me? I looked at her and said every night. If you were interested. As long as nobody knows. Yes. And she said good. I'd like that.

Today... It's been a long day. and now thinking about all of that, she's at a friends house spending the night, and i'm going to masturbate. Again...
