Last night, but mom was watching some dance program. I was determined to sit right beside her and cum. I sat down, opened my room and started to masturbate. Mom didn’t say a word. When it was almost over, I put my head on her shoulder, turned just enough it managed to cum all over her hands. They were in her lap. She didn’t say anything, and I was so excited, looking at her hands, covered with my cum that I had to do it again. When I was done I thanked her for letting me do it, then I went to my room.
