I went to visit my best friend. Once we were there and catching up, it came up in conversation that my friend's mother hadn't been with a man in a very long time. At the end of the conversation, they asked me what I was doing that evening and if I wanted to come to her younger sister's birthday party. I went to the party, and after a while, the guests started to leave. At one point, the mother stood behind me, grabbed me tightly, pressed her breasts into my back, and asked if I could help pack away the used chairs. I did that for her. Afterwards, I went to sit on the couch, she came to sit right next to me, and we ended up having incredible, explosive sex with a creampie finish.
