Mammary intercourse is a form of so-called "outercourse" (sex with a partner but without penetration). In this sex act, the man's penis is placed on the intermammary sulcus, squeezed between the woman's breasts and stimulated with an up and down sliding motion, usually with the aid of a sexual lubricant. As long as the semen is cleaned using soap and hot water, it is a form of safer sex with a low risk of leading to pregnancy.
When mammary intercourse is carried on to the point of the male's ejaculation, the semen may land on the woman's upper chest, neck, or shoulders, which gives this sex act its slang name of a "pearl necklace" (popularized in a song by that name on ZZ Top's 1981 album El Loco). |
