Jen started to feel a pressure building up in her ass. Looking around, she saw a bulge start
to appear. All of a sudden, a cows tail burst out of her ass.
"I have a cows tail!?" Jen shrieked in disbelief.
"Of course you do Jen." said Susan. "You've always been half cow."
Feeling a tingle in her body, she realised she was half cow. But the tingling didn't go away,
apparently having a cows tail isn't half a cow. Looking down she felt the tingling reside just
above her crotch.
