Someone mouths and sucks on a guy’s balls while giving oral, usually lingering on the sack with plenty of spit and sloppy tongue work. The art tends to frame tight close-ups of the cock and balls being handled, with the guy’s thighs spread and his partner working the nuts like they’re the main event. It often gets paired with handjobs or blowjob action, building up to a messy cumshot right after the ball play.
