My mom drank in excess all the time and often would be completely oblivious to what was going on around her. When I was in my mid teens with raging hormones she sucked my cock very often, sometimes every day of the week. She would never remember a thing and most of the time I cleaned her up after the sucking because she would stroke me off on her breasts. She could swallow my whole cock and often I would feel her tongue licking my balls while the head was deep in her mouth.
I played with her nipples, clit, anus and I would also tickle her until she could not talk, this often resulted in her peeing in her underwear. One time she even told me to put it in her but I did not do it, I just kept pushing it in and out of her mouth. I did find a vibrator in her closet though and used that on her often, she would just lay there with her legs spread wide and orgasm over and over as I rubbed it on her clit. I miss those days a lot, it was like having a personal sex doll that did whatever I wanted it to do.
