I had almost forgotten about this experience, but remembered it while looking at a family photo album.
When I was thirteen or fourteen, I had a bout of a nasty flu bug. I missed two weeks of school and was hospitalised for two or three days. The doctors allowed me to go home if my mother agreed to provide me with constant care. She slept in my room, either in a chair next to my bed or beside me, lying on top of the bed spread.
I woke up at 1:00 a.m. one morning, horny as hell. I had been too sick to masturbate for almost two weeks and I needed relief in the worst way. My mother was lying next to me, with a light blanket covering her shoulders. Her nightgown had hiked up and I could see her bare ass. The sight made me very aroused and in a state of delirium, decided to jack off with her next to me. I stripped off my pyjamas and slid closer to her. I started to stroke my cock and it wasn't long before I shot two weeks worth of cum all over my mother's bare ass. I was exhausted and drifted off to sleep, not bothering to clean up my mess.
The next thing I knew, the sun was up and my mother was getting out of bed. I was still naked and trying to cover myself up with the bed sheet. My cum had plastered her nightgown to her skin. She tugged at the fabric, trying to pull it away from her body. She looked at me and said, 'You must have had a rough night.' I told her that I couldn't remember!
