I wasn't sure about writing more because nothing major has happened or changed, but since there has been some interest I will.
Since the weather has been getting colder I haven't been going naked as much, but my son on the other hand still walks around the house nude as often as he can, especially since I started allowing him to masturbate more freely around the house, as long as he cleans up after himself. Don't get me wrong, I have really opened myself up to my own nudity and on a few occasions have simply wrapped up in a blanket on the couch, but when I'm cold, generally I want to stay in my robe or pyjamas.
Now, there have been times where we have still ended up naked together, with one night standing out. I was downstairs watching a movie with a glass of wine and this particular movie had numerous scenes of sex and nudity. This movie was on a channel that is known for showing some borderline pornography at night, and I was in the mood for a good, long masturbation session when I went to bed. It was maybe a half hour in and my son came downstairs, and when he sat down he said he couldn't sleep, and I told him he could watch with me. I figured there was nothing in the movie he had never seen before, so I really didn't think twice about it. He was with me for maybe 10 minutes when another scene came on, and it was showing the two main characters in a pretty wild sex scene, and I was getting really turned on, and I wasn't the only one. I glanced over and saw his penis sticking straight up and he was fidgeting around. I knew exactly what he was feeling so I just said to him 'go ahead, you can masturbate if you want.' 'You sure? In front of you?' 'It's OK, I know you need to.' He then reached over and grabbed a tissue from the coffee table and started stroking himself, eyes locked on the screen. My eyes weren't however. I kept going back and forth from the scene on the TV and the scene my son was making across the room from me, making long strokes, massaging his balls with his other hand. Just watching him pleasuring himself like that, I couldn't help it. I leaned against the arm of the couch and pulled my feet up, spreading my legs and gently rubbing my hard clit. I couldn't believe that I was there masturbating with my son, but I was so horny I really didn't care. My eyes were half closed and I don't know how long it went on, it could have been a minute or an hour. All I knew was, I was going to have an orgasm.
I was starting to really feel good when I heard my son breathe heavier and then let out a quiet 'oh..ohh...ughh...mmm...' I looked over and his head was leaned back and the tissue was wrapped around his penis, still stroking slowly. I have seen him cum before, but tonight he looked so adult, not just some kid jacking off, but an experienced masturbator. I closed my eyes and kept rubbing, and almost immediately I had my own orgasm, not a big one, but enough to hold me over until I went upstairs, head buried down and rubbing my feet against each other. I was just laying there curled up when I heard my son get up and asked me if I was all right, and I just giggled and said 'yes, I'm OK.' 'OK, good night.' 'Good night, baby.'
After he went back upstairs I was still horny, my orgasm not even close to satisfying me. I sat there and watched the last bit of the movie, sipping the rest of my wine and squeezing the carpet under my toes. As soon as it was over I shut off the TV and went upstairs for a second round, jumping onto my bed and spreading out wide, fingering myself and bouncing my butt up and down, digging my heels into the mattress. I don't remember much after that first orgasm, as I woke up the next morning, on my belly with my legs spread wide open on top of the sheets. I was cold so I pulled on my robe and slippers and went downstairs, my son awake and eating breakfast, naked as always. He told me good morning and that he had a good time last night, and I just smiled and said 'me too, but don't think that's going to be a regular thing', and he said he knew, but it was fun. I made some coffee and went back upstairs, drinking that before hopping in the shower to warm myself up and to masturbate again.
Sorry if this got a little long-winded, but just thinking about masturbating in front of my son, it got me turned on all over again and wanted to relive the details. Now, if you'll excuse me, I think I need to go masturbate again.
