I gave several bell stamps on Rachel’s butt cheeks after anal sex. Love them brown polka dots.

I left a nice little round cum crusty on Rachel’s forehead after sex with the old bell stamp.

A stamp achieved by good work, usually in primary school. Could be a smiley face or an animal! The stamp goes on your work or if you're really lucky on the back of your hand so you can show it off to all your friends.
