Ex wife and her husband texted to come over. Warned me in advan e to not get too excited because je simply wanted a b*******. She just watched me slow s*** him and talked to him as I did it. She said she understood why he was into it since I was doing it with such enthusiasm. Sort of made me wonder if I am the answer to what I suspect is her usual habit of her never being into sucking c***. He was tensing up as he got close to blowing in my mouth and she commented again saying it looked like I was probably better at it than she was and his voice cracked as he said for her to not be offended because no one was as good at it as I was and she told him to go ahead and c** in her f***** ex husband’s mouth then she plunged her tongue in his mouth and he lost it. I felt his balls contract and he was loud despite moaning into her mouth as he emptied his balls into mine. She had never said anything like that to me and i guess the filth/kink of hearing her call me that really did a number on him. As he came down she asked him if he wanted me to give her lessons so she could try to please him that way. He told her for sure and the thought of sucking c*** with my ex wife was insanely hot sounding. She said no promises but sbe would consider it.
