Mutant with one giant ball. The Testemorph often takes his sexual partner by force, male or felmale makes no difference to the Testemorph. The courting usually begins with a ball rubbing ceremony ending with full blown penetration of the anus, vagina, mouth or males anus. The Testemorph is capable of shooting an unheard of amount a semen. Sometimes measured in litres the ejaculate contains no sperm as the Testemorph is sterile.
After my tenth beer a drunkin testemorph jumped out of the bathroom and shouted "I'LL FUCK ANYTHING THAT MOVES!!".
