I've written a couple of stories on here that were part or wholly fiction--this one's the truth.
I've had a thing for my stepdad as long as I can remember. I have my problems with him in the real world, but I've always been horny for him. He's very straight and very religious, but he does like to look sexy--he used to get International Male and Undergear catalogs in the mail, and looking through them at night when he was asleep was very important to my sexual awakening. He didn't dress wildly, but he did have pretty sexy underwear from those catalogs--mostly black sports briefs, with a couple of statement pieces like a red mesh thong that I would love trying on and jerking off through when I was home alone. I knew he looked at porn--it was all straight, but I would still get off looking through his history, watching the same porn that he had gotten off to. I would find his cummy kleenex in the trash can of his office and smell them. This was all in middle school and high school.
He was comfortable with nudity, but I grew up in a prudish house, so I was disappointed when my mom asked him to cover up around us. Still, most nights when we would be eating dinner together around the TV, he would often be sitting on the couch in only a robe. I sat on the ground in front of him and used to try to make excuses to turn around and try to get a peak at his cock, which I did quite a few times.
I hoped I would grow out of it, but I haven't. I'm in my mid thirties now, and I still check his history when I visit home and get off to the same porn he does. He looks at porn a lot, including incest but more daughter stuff, still straight. Once I was home alone with him--he was in his bedroom and I was in the living room with his iPad, creeping on his history again. As I was on the browser, I could see what he was looking at in real time, and he was looking at porn right at that moment in the same house. I went to his door and stood there shaking for a long time but didn't get up the courage to knock and see if he wanted a hand.
On another visit a couple years later, I was looking at his history like usual and was thrilled to find some videos featuring trans men and one gay anal video, as well as views of a couple of PornHub "Am I gay?" articles! I came so hard that day and again and again for a few days after that.
My mom and stepdad just moved, and this past weekend I visited to help them unpack and move in, as well as keep my mom company while he was away. My mom asked me to help him out by sorting the boxes in his bedroom into the right place (they sleep in separate bedrooms). Needless to say this encouraged me and I couldn't help but look through the short stack of underwear he has already unpacked. Either he got rid of the flashier ones (I hope not!) or just hadn't unpacked them yet, so it was just a small pile of black sports briefs. They were laid out in a pile, unfolded in a stack. But there was one pair at the bottom that was folded. I picked it up and was surprised to see a pair of underwear that's the same as I wear--organic black cotton briefs. I checked the size--he always wears a Large, as confirmed by the rest of the pile, but this was a Medium. They were my underwear!
A bunch of thoughts went through my head. Do I leave them? Do I take them back and not say anything? Do I switch them out with a different pair of mine--let him know I know and play a game? They live a few hours' drive, so sadly I don't get over there more than once every couple of months, which would make it hard to play a long game. I decided in the moment to just take them back and not say anything--after all, I do like that pair of underwear.
But the next night I was jerking off to Nifty and my dirty side got the better of me. I sneaked back and took the pair back to my room, where I finished myself off to stories about stepdad/stepson incest and came all over the pair of underwear. I didn't want to be super obvious, so I let them dry overnight before putting them back, flipped around so you couldn't see the cum stains from the front, folded them the way I found, and put them back. While I was there, I stole a pair of his Calvin Klein black sports briefs, which I have at home now.
I'm shaking as I write this. I'm afraid that I read the signals wrong--maybe he really didn't notice they weren't his own, or maybe my mom thought they were his one day when our wash was mixed together. Maybe because I came on the inside of the crotch and then flipped them right-side-out, he never notices and just wears them once with my cum rubbing against his cock all day without, then washes them. But maybe he did know they were mine, and if so, maybe if he notices, he'll at least get a little thrill that I'm in on it, even if neither of us has the courage to approach the other. Or maybe this is the beginning of a game that will end in naked fun time together. Honestly, what I'd like more than anything is just for us to lie next to each other and jerk each other off--not more than that.
I left this morning and he got back this afternoon. I can't wait to see what happens.
