brotein exchange

To engage in an intense 69 session with a fellow male for (hopefully) long periods of time followed by swallowing each others loads.

"Dude, you up for another brotein exchange? I'm horny as fuck and my balls are full." "Same here bro. Horny as fuck too. I know you love the taste of my sperm. My parents aren't home so we can get together here."

brotein exchange

A potentially sticky situation where both you and your best bud are close and your mutual friends think you're both str8 because you have girlfriends, but you're actually surreptitiously meeting for gay/bi sex aka a brotein exchange. These hook-ups include alot of sucking each other off and swallowing each other's loads in addition to mutual foot worship.

When the girls thought we were spending the weekend at the shore, we were actually engaging in a brotein exchange at a motel down by the airport.
