It's embarrassing as hell to admit, because I've gotten away with it since I was 13, but Christ, I had no idea my step dad had knocked on my bedroom door (he said like 6 times), when I was in the middle of getting off. He told me later, much to a funny as hell conversation, that the only reason he came in after he'd kept knocking was because he heard something, and it sounded like something was wrong with me, and he wanted to make sure I was OK.

What he heard was me getting off. I'd been doing myself for about 25 minutes, had already gotten off 3 times watching porn on my laptop, and I guess he'd come up to talk to me about something. He said he knocked on the door, didn't get a response, knocked a few times again, and being respectful, he just walked in.

Hey, my step dad is hot. He's about 40. Good shape. Rides his bike. Exercises. Even fucks my mom good on an occasion when I hear them joking and laughing, and I know she's gonna get the D. But what's funnier, is that he checks me out, has since I was about 13 or 14, and long as I can remember, he's checked out my tits and ass. Doesn't bug me at all, because I'm pretty open about shit, and I'm sure if given a chance, I'd tap him. Mom or no. I get horny too. Guess if I didn't, he wouldn't have caught me getting myself off.

Laying in bed, when he walked in, I had my fingers down between my legs, stretched back, watching a girl getting pounded on the porn. Guy had his cock shoved so far up in her, you couldn't miss the fact he was probably fucking her lungs or something. Moaning, gasping, making all sorts of noise, and yelping his name. I'm waiting, fingering myself, watching the condom go in and out, and waiting. Yeah. I'd done this a million times. He'll blow his wad, pull out, the condom overflows, and he pulls it off, overflowing jizz on the bed sheets. It's hot as fuck.

Except this time, it didn't quite get that far. My step dad interrupted me, two fingers inside my snatch hair, orgasm half through, and he walks in and say "uhhhh" that lasted about 3 days. I'm not kidding. Stopped me cold.

Funny thing? I look. He's standing there. Staring at my pussy. Isn't moving. And I look, and he's got a hard on the size of Texas. Not kidding, his cock was so big, I think he could have fucked a whorehouse without even losing his boner.

I stop. Look at him and go "uh" and he stands there staring. I just laid there not moving. And he's eyeballing my pussy. Swear to God I think if I'd said "want to help" he would have buried that in me in about 3 seconds flat. Seriously. Mom or no mom, thought seeing my step dad with a big ass hard on was hot as fuck.

He looks at me, red in the face, and goes "uh" and yeah, walks out of the room. Disappointed. But I had a chance. I finished off. Got myself off like 4 more times. Last couple times, no lie, thinking about what his cock looked like, and how it'd feel just pounding at me. Goddamn.

I got dressed and went into the other room. He spent about 15 minutes apologizing to me, until I just laughed and said hey, I finished up after you left. Just delayed the end result a few minutes, but it's all good. He looks at me and says no shit? Really? To which I said I'm not gonna let a perfectly good orgasm go to waste. Too bad you weren't there. You might have seen a good ending.

He just kind of laughed. I pointed, couldn't help it, and said well, looks like you've got something to take care of too. I get an "uh, well uh yeah" and his face gets all red. Damn if I wish I had it in me to say how about I stay here and help you release it?

I was horny as shit later, knowing damn well he jerked it and most likely blew his wad. Told you, he's cute. I'd tap that, and fuck him good. But don't go there, not sure if I'd freak him out, and get busted by him ratting me out to my mom. Kind of hot knowing he's seen me naked, watching me get myself off, and knowing he went in there, probably thinking about railing me.

That's some hot as fuck shit right there. And I know I'd let him.
