Cum Suds

Cum Suds is when someone wears a dry condom during masturbation, and uses the cum of his first ejaculation as lube for their continued masturbation. After they're finished and they removed the condom, they will see that all the semen collected is somewhat foamy, hence the name Cum Suds

"Yeah dude! When I was done with that video, I had so many Cum Suds afterwards."
