The age old activity of recieving a blowjob while pinching a loaf and eating a meatball sub. Experts often let one meatball slip and splatter upon the female's head during orgasm.
Any fine sub or hoagie restaurant should have three rest rooms, one designated for Men, one for Women, and the largest designated for Blumpkins.

When you're taking a big dump on a toilet, and you're getting a blow job, you have an orgasm in her mouth as you let a turd drop.
