This time, the person who came to my sex room was "Riri". She is my daughter-in-law. For some reason, when my girlfriend's wife is out and Riri is at home, my cock tingles and I have a habit of twisting it into Riri's throat or vagina and ejaculating. At first, I naturally hated it, but now that I'm a fully grown adult woman, she's gradually grown attached to my proud cock, so when I put it in her mouth, she moves her tongue on her own and takes it inside my meat pot. When you do it, you naturally move your hips. I'm worried that I might get pregnant someday, but I can't stop this from happening.
