I made him cum only using my ass

I always knew my ass was special. Its the perfect combination of being strong, but so soft and juicy. At first I was just using my ass to tease him. I slid his cock deep between my butt cheeks and begin to flex. I could feel his cock growing against me and decided to keep going. I bounced my ass on his dick and kept flexing on his cock. He started moaning even more, so I wrapped my thick booty meat all around that cock. Apparently my booty was so good it made him nut!
