When Paizuri first became a big thing in hentai, it was most commonplace for the character giving paizuri to the second party to have large or huge breasts. However, in the past few years or so, this has become more varied. In many types of hentai, women of all breast sizes can give paizuri.
Some varieties: Double paizuri (involving two women performing it on a single penis), multi paizuri (same as double but involving more women), clothed paizuri, futa (she-male) paizuri, etc...
Jay: Any good?
Eric: Yeah, a lot of paizuri.
Jay: Teh titz!
I hope I can get my large chested girlfriend to give me paizuri.
Why don't you go paizuri yourself?
