When a girl is about to suck your dick, you punch her in the throat and while she's gasping for air, you put your cock in her mouth so she has no other choice but to use your dick as a snorkel to try and get some air.
1.) Cassidy came over my house the other day and I heard she was a freak, so I used the old scuba dick trick. Works like a charm every time.

2.) Cassidy had a great time at my house, she said she wants to come over tomorrow and go scuba dicking again!!

He asked me to join him in the bathtub and go scuba dicking
