Masterbathing

When you're taking a bath, jacking off and then bathing in your own semen.

"Goddamn it David, your masterbathing clogged the drain again!"

"Yeah, Kirk seems like a smart guy, but he's just too busy masterbathing to actually teach us."

Masterbathing is more private and intimate than dunk-tank-wanking.
