A customer experiences an unexpected creampie in my firm rear end

I was at the grocery store when I decided to stop by a store and check out some of the adult entertainment. The selection was decent, but nothing really stood out to me until I stumbled upon a customer who was engrossed in the anal section. He was busy fingering his tight hole, and I couldn't resist the urge to join in. I approached him, and he welcomed me with open arms. He began to lick my ass, and then he positioned me on my knees in front of him. He proceeded to fuck me hard and fast, but then he surprised me by cumming inside my firm rear end. It was an unexpected creampie, but one that I thoroughly enjoyed.
