after having anal sex with a female. the male removes his penis from her anus and wipes it on her nipples. then bends her back over on the bed and continues to have anal sex very very hard. in that process the now soiled nipples will make contact with the hopefully clean sheets. the resulting dots will leave a chocolate chip cookie pattern.
so no shit there i was doing this chick in the ass. when i pulled out, and she said you best not be done. i said, bitch im no where near done with you. so i cleaned my dick off on her tits and bent her the hell back over. after i got done railing her real hard i noticed the chocolate chip cookie on the bed. the name stuck.
