Bull here, I hope my experience will also be of interest. I had already been seeing this couple as a bull for several months. I have a 15.5 cm cock, but quite thick, the husband of the woman I was fucking I think was about 10 cm, she was a beautiful bbw brunette, with a very fat vaginal area. We had our meetings either in the morning or during the night, due to work constraints. One morning I arrived late, her husband had to go to work by now, they had already had sex, I apologized for the delay, she was still in bed with her legs spread, with an incredible amount of sperm dripping from her vagina, her husband despite a small cock, he had very big balls, definitely bigger than mine, objectively a little tight. Her husband asked me if it wasn't a problem for me that he had already ejaculated inside her, I answered no, in fact I was getting sexual excitement at the idea of doing it after that situation. I undressed, my cock was already getting hard, I approached his wife and after several kisses and a sloppy blowjob, I decided not to waste much time and try to stick it in her already filled vagina. One of the most incredibly pleasurable sensations I've ever experienced, so slippery and perverted, I usually ejaculate after about ten minutes, that day after barely a minute I felt the ejaculation mount, I planted my cock as deep as possible and added my cum to that of her husband. Even she was confused, I apologized saying I had gotten carried away by the situation.
