my best friend loves my fat ass

we had plans to watch a movie but it takes you forever to get to my house. when i ask you why you say you were trying to jerk off but your gf is out of town and doesnt like you to watch porn. i decide to help you. i let you jerk off while i tease you with my ass. i spread, wink, slap, shake and bounce my ass for you while you masturbate. i then give you a bj until you cum but your so distracted you accidentally cum in my mouth.
