I lost my job and have been staying at my parents' between jobs.
It started when I was young. I saw my mom's perfect body when she had come out of the shower and never forgot the image. In high school, my first wet dream was when I dreamt about her. I pushed these thoughts away for a long time. By college, some guilt starting going away and I started masturbating to the thought of her, and stealing her panties to smell and jerk off with. I never came in them for fear of getting caught. The fantasy came and went over the months and years, depending on how hot things were with my girlfriends. This continued to my late 20's. At that point, when I saw her in person, the naughty thoughts would usually go away. This continued for a while until recently. Within the last couple of years, the naughty thoughts have not been disappearing completely when I'm in her presence.
A couple of things have happened to precipitate this. She saw me shirtless in a pair of old gym shorts, no underwear on in the laundry room and I had just got out of the shower and was real clean and fresh, my junk was kinda visible and she looked down at my dick, looked up at me and then we both laughed for some reason. Kinda awkward. I started to wonder: 'was she turned on by that?' Then there was another time we were out of town and I accidentally walked in on her topless while she was changing. On the bottom half, she just had on black nylon tights. I stared straight at her tits (eyes automatically went to them, I don't think I could have stopped them) and we both started laughing again. Finally, and most recently, we were alone in the house the other day and upstairs we were just talking and I gave her a spontaneous hug. I could feel myself get turned on. I rubbed my crotch on her JUST slightly. It wasn't overt, but probably slightly noticeable.
One day I decided to be bold and jerk off into my favorite pair of panties of hers. Her white cotton bikini ones. I had never done this, and I knew it meant that there would be a risk of getting caught, but I decided to just roll the dice. She in theory could have assumed it was my dad who was the culprit, or not noticed that they had been cum in. So there was a reasonable chance she would never know what I did, and not give it a second thought. But if she suspected it was me and it turned her on, that's what I was hoping for. It would then be 'her move' and if she didn't make her move, I would have probably stopped things there and focused my fantasies elsewhere. Trouble is, she did make a move back. Last week, she left a laundry basket out in the hall full of folded clean clothes, ready to be put into her drawers. On the very top, it was the same pair of white panties I had nutted into. She left the hamper out ALL DAY when she knew I was home and passing by it a lot. I assumed this was deliberate on her part, so I decided...after a lot of thought...to jerk off into them again to see what would happen. The reason I am writing this now is because it's four am and no one will catch me writing this, and when I got home earlier tonight (about midnight), I got home, went upstairs, saw my mom had made my bed. I brushed my teeth, turned out the light, undid the sheets to climb into bed and guess what was neatly placed on top of my pillow?
