Erika tried to pull the sheath of fur down but it was firmly attached to her abdomen.
However, the touching had caused an erection. She was even more shocked as a moist pink piece of flesh grew out of the sheath. It wasn't human, it was deformed. About the same diameter as it should be for a boy of her age but it was pointed at the tip and my glans was missing. Then she noticed a bulge just inside of the sheath. Erika pulled the flesh part of the sheath on the skin and the bulge popped out. This caused her dick to become fully erect and the bulge to expand.
