A couple engaged in mammary intercourse
Mammary intercourse describes a sex act, performed as foreplay or as non-penetrative sex, that involves the stimulation of the male penis by the female breasts. Commonly, this sex act involves the man placing his penis in the woman's cleavage and thrusting between her breasts, while the breasts are squeezed around the penis for additional stimulation. Mammary intercourse can also be combined with fellatio.
It is known as titty-fucking or a titfuck in the United States, as well as tit wank or French fuck in the United Kingdom. The Japanese sex industry uses the term パイズリ (paizuri) (from おっぱい (oppai), a slang word for breast).
Since mammary intercourse is a non-penetrative sex act, the risk of passing a sexually transmitted infection (STI) that requires direct contact between the mucous membranes and pre-ejaculate or semen is greatly reduced. Notably, HIV is among the diseases that require such direct contact and is therefore very unlikely to be transmitted via mammary intercourse. A study of the condom usage habits of New Zealand's sex workers said that they offered various safe sex alternatives to vaginal sex to clients who refused to wear a condom. A sex worker said that mammary intercourse was one alternative used; mammary intercourse performed by a woman with large breasts felt to the client like penetrative vaginal sex.
