About two weeks ago, I was in the living room on the computer masturbating. Quite honestly, I do it at least 4 or 5 times a week. I love watching porn, and I won't lie. I love the feeling of making myself hard, playing around, and then when I'm feeling it right, getting myself to blow. I've done it a bunch of different ways. Sometimes in a dish towel. Sometimes with paper towel. Other times, I'll use a condom, and fantasize that I'm fucking some girl, wrapping it tight, and I'll blow my load into the condom. Then when I'm done, I'll go into the bathroom, limp, my cock soaked with cum, and take the condom off, throwing it in the toilet, fantasizing I've just gotten done fucking someone (usually someone I'm not supposed to). On occasion, I'll end up actually getting so horny I'll masturbate again like a half hour later, and do it all over again.

I was in the living room, in my computer chair. And I had unwrapped the condom. I had some solid porn on, that I most times use. This one was one of those "hardcore russian" porn videos, with a guy mid 30's, and a girl that I bet honestly was at least 18, because you know they can't use underage girls in these videos, but in truth, she looked about 15. And this was labeled as "daddy/step daughter". I have it saved, so I can go back anytime and watch it. And I often do, fantasizing that's me, condom on (he's showing her how to put one on, he fucks her, and he cums in it. Pulls out later, and he does mostly what I do when I masturbate). This time, I'm in my chair, ready to get going at it, have the condom out, and haven't put it on yet. And my niece walks into the living room. I had no time to do anything whatsoever. She walks in, and in shock looks at me, and then laughs. And says "oh damn." I didn't know what to do. The condom is sitting on my desk. My pants are around my ankles. And yeah. My dick is standing straight up. Not going to hide that. She's standing about 20-25 feet away from me. And she comes walking over. Like it's nothing. Looks around the corner at my monitor, and says "Oh wow. That's some sexy shit right there".

I looked at her and said "holy shit. You're something huh?" and she looks (I've pulled up my shorts), and laughs and looks at the condom, back at me, and says to me with her eyes wide "who's something?" I just laughed and said "Come on Riley. You can go upstairs now" and she laughs and says "so you can finish your business" to which I wasn't going to lie. I said yeah. I am actually. And she looks at me and says to me all serious "uh huh". I said "what do you mean uh huh?" and she looks at me and says "I wanna watch". I just laughed and said "no way are you going to watch. I'm not going to let my niece watch me jerk off" and she laughs and says "well I've already seen your junk. So it's not like I don't know what you're going to do". I have no idea why it sounded appealing. I'd never done that. I'd always done it on my own. Nobody had ever seen me do it. This kind of scared me, thinking if she said something to my brother, to my daughter, to someone, etc. And she looks at me and says "oh come on dude. You might find it kinda hot. Letting a girl watch you jerk it". I just looked at her and said "yeah. If you wanna" and she said "Yup. I actually do wanna. So have at it". And I said well. I was nervous. I actually didn't know what the hell to do. She sits up on the arm of the couch next to my computer, and says "have at it. I wanna see" and I kind of laughed and said OK then.

I got the porn going, and it's got the guy and the girl talking on a bed. They're talking for a bit, one thing leads to another, and then stuff starts happening. I have the condom on my desk, and my niece says "so this is when the good stuff happens huh?" I said yeah. I looked at her kind of sideways, and pulled my shorts down. My dick is standing straight up. She looks at me, looks at the condom, and goes "holy shit. You role play it out? You act it out like you're gonna do the chick?" I just laughed and said yeah. That's the idea. And she looks at me, and says to me with a laugh "holy crap. Fucking hot stuff right there. I wanna see this". I just laughed and said keep watching, and you might and she says well OK then.

I was sitting there, stroking slowly, and I was getting super worked up. She's watching me, glances at the condom, glances back at me, and I said "unless you wanna role play" and she says "and I'd do what?" I just looked at her and said never mind. And she says to me "No, don't never mind me. Tell me", so I said "well if you watch the rest of the video" and she says "they fuck?" I said yeah. And she says to me "he pop?" I laughed and said "yeah. usually what happens". She hesitates. And says "I don't wanna ruin your fun. But another time?" I about died. I said "what?" and she laughed and said to me laughing, "I'm ragging. Sorry to let you down". I just nodded and said well OK then. And I sat there. I didn't know what to say. I said "you're serious?" and she says "I've never done nothing like that. But sure. I mean, maybe" and just left it hanging. I said OK then. And didn't say anything else.

I went back at it. She's sitting there watching, glances at my cock, glances at the condom, and I'm ready. I'm there. I reached over, I pulled it off the desk, and I pulled it down. I wrapped my cock with it, and I pulled it tight against my balls. She's sitting on the edge of the couch watching. And as I'm stroking it, I'm watching the dude fuck his chick. I know the time frames on the video, so I know when he's gonna cum. And right about the time I'm going to do it, and he's going to cum inside her, I let loose. My niece is sitting there watching, as I'm pumping, thrusting my ass in the air, thrusting my dick inside the condom, and squirting cum. I'm completely filling it up, and she's watching as the cum goes inside the condom, and it surrounds my hard cock. I keep gasping, moaning, and grunting as I'm cumming. And when I'm done, just as the guy in the video is done, I finally gasp and lean back.

I just sat there. And I hear her go "holy fucking shit dude. That was intense. And that was mighty hot as fuck". I just laughed and said yeah. It was. And she says to me "I wanna see". I looked at her and said see what?" and she says "I wanna see". I unwrapped the condom off my cock, and pulled it off. it was full. She just stares at it, and says "damn. That's pretty sexy right there. Hot shit". And I kind of laughed. I pulled my shorts and underwear up, and said "well now you know".

She got up, I got up (all sticky and soaking wet), and she walks up next to me. And says to me "that was awesome. Thanks yo" and walks up the stairs to bed.

I'd never believed I'd let my niece watch me jerk it and get off. Yeah.
