Not sure if this really counts as M-F, but it is technically. So a few weeks ago on a Sunday night I went to bed before my wife, as I had to be up early on Monday. I was asleep when she came to bed, but her getting herself settled in woke me up. I attempted to go back to sleep. As I was lying there I started thinking how nice it would have been if she had come to bed interested in a romp, but no such luck.
Within about 10 minutes she was sound asleep as I could tell by her breathing. I rolled over facing her and noticed that her right breast wasn't covered by the blanket, just the thin material of her tank top. My wife is an extremely large breasted woman, about a 42 G cup, and her right breast was straining the material to stay inside the tank. This I realized also caused the tank top to gap below her breast. Knowing she was fast asleep, I reached inside her tank top and started rubbing her breast. This had an effect on both of us as I started to get a rise in my shorts and her nipple became very erect. I kept rubbing, enjoying the sensation.
At this point I realized that her right hand was down by her side clutching the tv remote. Hmmm. I wondered if I could replace the remote with my hardening cock? Now I needed to reposition myself, out from under the blanket and closer to her, while also sliding my shorts down. I moved into position, slid the remote from her hand and replaced it with my hard cock. Her warm hand felt nice around my erect cock. I closed her hand a little to let her get a better grip. Using my left hand on her wrist I was able to stroke myself with her hand.
As I slowly stroked my cock with her hand, I began to play with her breast again with my right hand. As I did her nipple became erect and my cock got harder, it felt great. In some ways I was hoping she'd wake up and finish but she was sleeping away and I was working towards a nice orgasm. As I got closer to cumming, I took her hand in mine, moved her hand down my shaft and got ready to explode all over my belly. It felt great as I erupted on my belly, feeling my hot cum and her warm hand as I stroked out the last of my orgasm. I grabbed a t-shirt, wiped her hand off, cleaned myself up, and went back to sleep. She never woke up and she hasn't said anything. Not sure if the circumstances will work out to try it again but it was fun as a one off.
