The ejaculate of a penis stuck in the ball fro of a man
Anthony came, but was distracted letting all his semen drizzle down to his ball fro, forming a cum nest.
A place of your home that is used for sex-having. Could be a bed, your couch, kitchen countertops, etc. Whichever is most used.
“Peter is that your cum nest? That looks awesome”
“Yeah that’s my cum nest, I just used it last night”
“Sick bro”
