The results of performing oral sex usually, or any means including PIV, fingers or toys, to bring a girl to orgasm when she has a full bladder. Ideally she holds her bladder until she acheives orgasm, but may be released when she simply cannot hold it anymore.
The result is usually the nuclear bomb motherlode of squirting.
Man, me and my gf were chuggin' beers last night. I went down on her and she hadn't used the toilet for over two hours. When she came, she gave me the fountains of venus in a major way! Had to replace my couch and carpet, goddam it.
