eat the cookie
When a group of guys jack off on a cookie, and the last one to cum has to eat it like it's the worst punishment ever.
They all came on the cookie, and the last one had to eat it like it was a used napkin.
The last guy to cum on the cookie had to eat it like it was a rotten apple.
He was the last to cum and had to eat the cookie like it was a cursed sandwich.
