You stick your cock in the hole of the plastic wall of the stall, closing your eyes, praying for this to quick. Suddenly, you feel something sharp bite into your dick, breaking the skin. You pull back in shock but it doesn't let go. You don't know why but you feel your penis tense up and the creature on the other end gets started. You don't want to, but you can't help but enjoy it, it feels so primal and other worldly. You stop resisting and just let him keep sucking away, slowly building up to your amazing climax. You let out a shriek in delight. A shriek that scares you, one that's not human but almost sounds bird like.
You open your eyes and your hands now are boney and yellow, tipped with sharp talons. Your arms are covered in brown and white feathers. Scared, you rush to the mirror, not even tucking your cock back into your pants. You are no longer human, instead you're an anthro hawk.
You hear a door open behind you and it's another anthro hawk, but he's massive, 8 ft and incredibly muscular, scar on his left eye, wearing a guards uniform. He grabs a paper towel and wipes your seaman and blood off of his beak.
"Hope you're not mad you don't have wings. Not like you could fly anyway." He says laughing. "Don't worry though, you're going to be perfect." He bares his sharp talons and jams them into your back. You start feeling dizzy from pain and collapse onto the bathroom floor.
