Chocolate collar
At the end of anal the "top" lays face down and the "bottom" gets over the top of the others upper body and rubs their gapped ass across the others neck creating the "chocolate collar"
Bro I totally gave the hoe a chocolate collar at the end of that garbage sex!
Chocolate Starfish Collar
The act (sexual) where a person or animal rubs their naked anus on the back of the other persons neck.
She had massive hooters, but I could only come when she gave me the Chocolate Starfish Collar.
