I received an offer from my stepsister to buy sex with her untouched rear, which turned out to be incredibly tight.

I was at the gym with my stepsister, and she offered me money to take her virgin ass. I had no idea it would be so tight, but I couldn\'t resist the offer. After some coaxing, she got on her knees and spread her ass for me to fuck. It was a wild ride, and I ended up cumming inside her.
