Fuck His Ex's Ass On First Date

I bet my buddy I could fuck his ex-girlfriend, a shy teen chick from college who never let him fuck her in the butt. On our first date, I took her ass to mouth and came deep inside with a nasty anal creampie. I rubbed the sperm into her anus like extra lube. She let me do it all on the first night, despite never allowing him to go there before.
