Custard Donut
Slang for anally cumming in somebody so it looks like custard oozing out of a donut.
“Oh man Aedan, I gave Natasha a custard donut last night it was fantastic!”

The aftermath of hard anal sex with a girl (without using lube). When the guy has spilt his custard into her ass and her sphincter is swollen, the custard oozes out creating a custard donut. Optional to get her girlfriend to lick it out.
Man, I give it to her so hard up the ass, then made her friend eat the custard donut.
