o ring blowout

From massive amounts of anal sex, sphincter muscle becomes so loose that ones shit falls out staining ones socks.

Bruce was speed-walking in the park Monday morning after a long weekend in Palm Springs, when he suffered o ring blowout. His butt hole opened the size of a fist, and a turd fell out staining his left sock.

O Ring Dominated

while having sexual intercourse thru the anus right before ejaculation the man punches his partner in the neck. her body freezes up clenching the butt hole on the males shaft. as he forces his dick out the o ring comes out of the anus. he then cuts it off very precisely and either wears it as a bracelet or necklace for a souvenir.

while fucking this girl i O Ring Dominated her and i still wear her on my wrist daily.
