Corbin looked at his friend in horror and decided this was the only option "Just let go...let yourself change". John was kneeling now blood thumping through his veins. In an instant his chest burst forwards spiralling him onto the floor. He started to undress his trousers pulling off his pants. His cock was growing as well cracking it released itself from the lining of the pants and elongated up. He groaned in pain as his voice got lower. His entire body was rupturing in muscle, ripping through his clothes tearing them piece by piece.
He pushed himself forward as his back cracked, His screaming was disappearing. Strange. Instead he was now groaning with pleasure, like it was a satisfying experience. John was letting himself change now, his skin now darkening and forming large amounts of fur, his cock rupturing and becoming harder. His neck expanding and growling. He was now covered in fur completely. His skin got more leathery, the claws on his hands got longer.
Out of his head petruded 2 horns, his entire body was now resembling corbin but more muscular and monstorous. He screamed in pleasure as his body kept increasing in muscle mass. Then he stopped. He stood up now 5 times bigger than Corbin staring down at him. IRL corbin stopped playing and looked at John, he was lying on the floor violently shaking, rubbing his cock. He was now increasing in muscle mass too. Corbin was panicking, he couldn't let this happen.
But Corbin grabbed him in real life, his muscles too strong for Corbin to escape from. He pushed at John trying to escape but he couldn't. John screamed "JOIN ME CORBIN". He pushed his cock against Corbins and to Corbins horror John's cock was joining to him. John lowered his body onto Corbin, now their bodies were fusing together. Corbin screamed trying to escape "John no!" But now he had a bigger problem he had this weird sensation, he was enjoying the changes. He had to resist it. John was now fully absorbed in him, now Corbin was the only one there and increasing in muscle size. He lay on his ground rubbing his cock trying to stop the transformation, but he couldn't anymore. He was now a passenger and he felt the energy rush into him growing him outwards.
He didn't know if he would stop growing, but Corbin didn't really care anymore.
