Cockqualung

The highly valued skill of being able to suck dick underwater without taking a breath for a long time.
Sheila used her cockqualung to go down on me for the longest time while we were in the pool. I blew my wad and she wasn't even out of air yet!

blood helmet

When a girl on her period sits on your forehead, leaving a crusty red coating.
I had my girlfriend sit on my face when she was on the rag, and she gave me a blood helmet.
