You should try licking his ass if he wants to. Have him scrub up extra good maybe even shower together for a fun sexy yet practical reason. Then rim out his ass !!!!! you can even use flavored lotion made for eating out pussy and ass. You can bend him over rim his asshole then reach around with a well lubed hand and jack him off its called a rusty trombone. I promise he will propose marriage to you right after he cums
