In my line of work I have met a lot of people and in the days of apartheid with draconian censorship people especially men had a lot of issues and loveless marriages etc were quite a norm. I had a tv and video to do presentations so sometimes I would have witblits coffee evenings and people would bring some porno movies. All but one of the guys had left and the last person and I were chatting he was from the insurance industry. He said his first girlfriend and he used to cock tease her mother was an alcoholic and would fall asleep and they would then fool around. She would take her panties off and slide up and down his cock without penetration, untill he came. all a bit messy but that was their thing. One night they were deep at it and he was close to cuming when the door opened and the mother came into the lounge to go to the kitchen. He got a fright and she got a fright and in her surprise she opened and sat down on him. For him it was full penetration and he started cuming. He could hardly mumble good evening when he was reduced to a gasp as he ejaculated into her. She got a fright and clamped on him as he was cuming and started to moan and both tried to pretend nothing was happening as the mother made it to the kitchen.
