A [[tag group:sex acts|sex act]] in which a person (male or [[futanari]]) has their [[penis]] rubbed in the [[cleavage]] between their partner's [[breasts]]. Also known as "titty fucking" or "mammary intercourse". On Danbooru, the Japanese term 'paizuri' (ぱいずり) is used.

If the penis is long enough, [[fellatio]] may also be involved at the same time.

If "paizuri" is performed on an object instead of a penis, use the tag "[[simulated paizuri]]" instead.
