O-ring Domination

After you give someone a pink sock, you cut the sock off and wear it on your wrist.

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.
