Shack the cheeks 

A situation during sexual intercourse when a man ejaculates explosively in between the butt cheeks of his partner. He then would vibrates the butt cheeks of his partner while his semen drips down their crack.

Chris - Listen baby, im not trying to have some candle light dinner over wine tonight. Im just trying to shack the cheeks.
