That has to be sweat since if that's all nut juice that's literally impossible. He did seem to pound the eff out of his gf seems she atleast into his dee. Seems the only thing each girl cares about from him is his dee. Glasses isn't a cuck but his friend sure is. Some how his girlfriend will push him into being swingers.
Glasses should just forget love and be happy to eff both of them after beating a couple times he should cut off ties with all of them.
