Flocking

When a women gently flicks a man in the testicles for his sexual pleasure. A gentler form of Tamakeri, (literally ball kicking) or ballbusting, a sexual fetishes in the BDSM community.

Tamakeri is the Japanese term used to when Asian women hit men in the testicles for sexual pleasure of the man. A form of BDSM, in which the sadist hits the man in the testicles, and the masochist is hit in the testicles

I love Flocking because it is a more loving and tender form of ballbusting.
