Mark seemed to return to sanity, staring at you with wide eyes. He stook a step forward, but you stepped back. You were furious, horny and lost in a daze of incoming bliss.
"Oh I am so sorry!" Mark managed, before his face became contorted as he stumbled backwards. Bracing himself against a tree, Mark let out a deep and primal sigh as a post-induced bliss took its full hold of him. Once standing at 5.2 ft tall, Mark began to grow, his limbs and proportions spreading outwards until he reached 7ft tall. He stared at his newfound heighted, panting and cooing as he collapsed onto all fours. Rolling onto his buttocks, he spread his legs wide as his groins boiled and itched, watching as his penis grew to 10inchs long.
His new form was tall however his muscles seemed to lag behind in this growth. They were taught, defied with every muscle cut and defined like a slightly bulkier runners build - Perhaps this would change as his curse developed - but he was overtly athletic in appearance. His hair became more wild, his face still boyish but his pubic hair now growing thick and wild.
As all these new changes took place, you felt your own bliss hit you like a rocket. Sighing with a almost primal relief, you fell onto you back, with regret, letting it all in. Your legs were now horribly shaggy, so packed and dense with curly black hairs it was beyond human. Your forearms itched as they became dark and hairy, reaching a sate similar your your own legs before your latest emission. You watched your pecs become layered in a fine coating of chest hair, with the trail from your bush to your navel traveling thickly up to your own chest. There was now a complete covering of scruff along your jawline, your hair growing too: It became a thick mope of curls! A far cry from the shaven scalp you entered in. Your nails looked sturdier too, becoming hard and sturdy. Your own changing loins felt the best, you stared at it with a sickening excitement, as it throbbed and wriggled to 12inches in length. Your balls began to swell too, no doubt bumping your body with beastly testosterone. It looked hairier too, with your balls now becoming dense with hairs that began to stumble around the base of your shaft! You were very hairy, and closer to the curse overpowering you.
You and Mark slowly rose to your feet and stood in silence.
