Sex Brownie 

When you're doing anal and your partner shits on your dick, so you make them lick it off while giving you a blowjob.

Ty: Dude, this girl I hooked up with shit on my dick!
Joe: Did you make her eat your sex brownie?
Ty: Hell yea!

Brownie Sex 

Making large quantities of hash-brownies, eating them, and then having sex while experiencing the chocolatey deliciousness.

I heard Franklin and his girl had some brownie sex last night.
