For Men: It "taint" your asshole or your balls, it's the skin in between.
For the Ladies: It "taint" your asshole and vagina, it the skin in between .
Daughter, "I pulled a muscle."
Mom, "What did you pull?"
Daughter, "That area between your asshole and vagina. "
Mother, "Your taint!"
Daughter, "Ohhh, that makes sense."
The region of skin in between the vagina and the asshole. Comes from the notion that when wiping oneself or performing heterosexual sex the receptacle (the piece of toilet paper or dick) penetrated by means of piss or vaginal fluid now has the power to "taint" the asshole when venturing south of this region
I decided to move in pastJen's taint and try some butt stuff.
