I received an offer from my stepsister to purchase her untouched rear end, unaware of the incredible tightness I would encounter

I was working out at the gym when my stepsister offered me cash to take her virgin ass. I accepted, and we headed home. She lay on the couch, ready for me to penetrate her tight hole. I was surprised by how snug it was, but I didn\'t want to disappoint her. After some initial struggles, I managed to penetrate her, and she moaned in pleasure as I filled her.
