Nate starts to panic as he sits up in the bathroom, his fingers and toes still throbbing from the change, his heart racing. The changes didn't stop there though, the tension just slowly dissipated before he felt his cock harden. He looked confused between his legs, the throbbing feeling he just felt moments ago, now flares up as his cock grows with each heartbeat.
"Woah...woah no please stop..." He groans out loud and tries to stand up, his cock now throbbing painfully. Without him realizing, a thick canine penis bone is starting to form inside his cock. His cock is facing towards his face as the new bone forces it to change slowly. It feels like the skin is bursting as the bone forces it to slowly change shape. He winces in pain before it starts to throb in pleasure, precum starts to leak while his foreskin starts to loosen.
"Nghh oh fuck....no, I have to stop it...." He groans and slowly limps towards his bedroom, a shiver running down his back each time his claws scrape on the wooden floor. His still human foreskin now starts to pull back, the sensitive skin on his gland spreading all the down to the base, the shape of his gland looking off while two bulges start to grow on the base of his mishappen human cock.
