When a boy has not washed his penis for an extremely long time and the excess semen around the rim of his penis has formed a hard crust known as Cock Cement.
Boy: ''Oh babe your mouth is so soft''
Girl: ogfhadfhadhd
Boy:''This is brilliant''
*Girl releases her mouth from the genetalia*
WOW Barry you have a silly amount of Cock Cement on there!
