The act of propping open a woman's anus with a
metal ring and placing one's
testicles in her. Remove the ring and the testicles
will be trapped inside her until the women releases her sphincter and passes stool. The act of the woman shitting one's testicles out is called "fifth base".
My girlfriend wanted a little more than anal
sex last night so i decided to take her to fifth base. The ring
hurt her but not as much as her ass
hurt me!
