Three years ago when my step daughter was still in high school, she came downstairs into the living room and caught me masturbating. I wasn't quite there yet. I had a paper towel wrapped around my cock, was watching porn, and as typical, was waiting to cum. It usually happened that way. Except that night, she walked into the room before I could quite get there. I tried to cover it up, but it's hard to hide an erect cock, trying to shove it back in my shorts, and do something with the paper towel. Jamie came over, and looked, saw the porn, saw my cock jutting out of my shorts, and kind of laughed and said "whoops".

I just looked at her and said "Jesus. This is just weird" and she laughed. She just said "It's not like I haven't seen a dick before. Just yeah, not yours". I just laughed and said "well thanks for letting me know that". She sat on the arm of the couch, and said "well don't let me interrupt you". I laughed and said "you are so not going to watch me" and she shrugged and said "why not? I mean, it's nothing I haven't seen before. Just curious how you do it". I was curious. So I asked her some questions. We talked. And she said "I was serious. I wanna watch". I guess I was curious what it'd be like to show someone when I was jerking, so I just said OK. And when I started watching the porn again, i was expecting her to leave the room. And she didn't. So when it actually came time to "do it", I was hesitant. But I pulled my shorts down and I was sitting on my computer chair on my bare ass, with my cock thrusting out. I grabbed the paper towel, wrapped it around, and I heard her say "that's how you do it? That's hot" and I just laughed and said well thanks. She just laughed back and said you're welcome. It was a bit awkward and creepy, but I really wanted to get myself off.

When it got to that point, she was sitting on the couch. And I reached the point where I was going to cum. I slowed down, and I said to her "you really wanna see this?" and she said "yep. I really wanna see this. So have at it". And I did. A couple more strokes, and I came. I was watching, and I gasped, panted, and squirted it into the paper towel. She looked at me, watched me finish, and when I leaned back, she says "can I see?" so I showed her. Felt weird. And she looked and saw my dick limp and said "well then" and just kind of looked at me.

She got up and walked out of the room afterwards. And when she came back, we sat on the couch and talked. After letting her watch me jerk off, I desperately wanted to do more that night, including fuck her if it was ever possible, but it just didn't happen. Not then.
