titty fuck.
Mammary intercourse, also known by many colloquial terms such as titty fuck, is a form of so-called "outercourse" — sex with a partner but without penetration. In this sex act, a man's penis is placed on the intermammary sulcus, squeezed between a woman's breasts and stimulated with an up and down sliding motion, sometimes with the aid of a sexual lubricant.
When mammary intercourse is carried on to the point of the male's ejaculation, the semen can land on the breasts, face, or in the mouth of the woman. The appearance of semen landing on the woman's upper chest, neck, or shoulders gives this sex act its slang name of a "pearl necklace".
