Rodger's squirming continued as a thick flow of pre eminated from his dick. You and Mark just stand there in shock as Rodger starts to lose control. "I can't...I must...urghhhhhh" Rodger moaned as he fought against the lust rising through his body. He punched the tree again, trying to get rid of the lust through anger. You could see his dick visibly throbbing as he struggled to contain his feelings. His right hand was slowly making its way to his dick as Mark cried "Fight it Rodger!".
But it was too late - Rodger's hand had found his dick and started rhythmically pumping it. With each pump, his groans grew louder and louder as the covering of hair on his body started to get thicker. "Urgh...ah...ah...aaaah". The pre kept flowing from his dick as it grew in size. His face started to broaden and his nostrils began to flare. He didn't notice any of this, now completely lost in his lust induced state. His shoulders broadened further, and his pecs and abs became even more defined. "Ah...ah...ah" Rodger continued in his now slightly deeper voice. The more he stroked his dick, the more bull he became.
You couldn't stop, almost hypnotized, watching the lust induced scene before you, your dick still almost painfully at full mast, leaking pre. From the corner of your eye, you notice Mark was having the same problem - but suddenly, he snapped out of it, running toward Rodger in a vain attempt to stop him.
But it was too late and Rodger was too far gone, so that when Mark reached him, he was already nearly fully Minotaur. As Mark reached Rodger, Rodger let out a series of fast groans, "Ah...ah...ah...ah...". And then he gave out a deep roar as his huge dick began to orgasm. "Urgh....aaaaaaaaahhhhhhhhhhhhhh!" he cried, as copious amounts of cum began to fire out of his dick, and all over Mark's body.
By the time Rodger, now a fully muscular and beefy Minotaur, with a bull's head, tail and dick was finished orgasming, Mark was covered from head to toe in his cum.
