Peach pimple

The action of sucking on your partners bum cheek to remove the puss from an especially painful spot on the left cheek

Peach pimple can be defined by asking your partner to get on all fours and take a deep breath to prepare for the extraction of a painful spot on the left cheek of your beloved partner. All puss must be removed in one suck and a pinching can be allowed with thumbs plus fingers.
