"I want to be like you!" You howled.
Andy just grinned at you, and you could have sworn he blushed for a moment. Wrapping a firm shoulder around you, he drew you in for a kiss. You relented to it, securing any urges to flee well and truly away. Your skin was sweaty and your chest covered in a decent amount of dark hairs, but still to remained thin and not at all an example of spartan hood. Your rod vibrated with excitement, of the future and of the flesh. The kiss ended and for a moment you felt numb without Andy's touch, but suddenly a blast hurricane of pleasured shifted you forwards and forced you to moan. You then realized Andy was stroking your cock with godly expertise. His hand moved up and down, shaft to leaking tip - he made sure to hesitate and fiddle with it to stimulate and tease your senses. You spread your arms wide against the cavern walls, desperate for some sense of grounding as the forest lust gripped and squeezed you for all you had.
You could feel yourself getting stronger, your arms throbbing with energy as they grew larger and swelled with strength. You turned to look downwards, admittedly a struggle for your eyes watered with bliss, to see your legs slowly blossom with slim and yet firm muscle. Your thighs remined slim but as you watched you could see that firmness contrasted by your enlarging thighs! Watching your shifting legs, you now could see dark hairs spread across your legs and eventually cover your stocky thighs.
You pores began to reek with the scent of the forest, but were not yet completely changed. Yet the possibility that they would be was maddening to you.
Moaning, you leaned further back against the wall and began to slowly slide to the floor. Andy pinned one hand against your chest, feeling the dark tangle of curly hairs that now covered your pecs. You tuned down at them and watched them swell with muscle. It was then you noticed how your fringe that covered your eyes consisted of dark locks. Though the bliss you managed to run a shaggier arm though it and admired the thick and healthy curls that hung from your head.
Your sweaty skin glistened with sweat and as you began to admire your thicker body you noticed your skin tanning. It almost glowed as it transitioned into a copper-like gleam! A richness you knew was not just a simple product of sun exposure, but a natural mark of your Greek Spartan blood. Your jaw itches as shadow of hair spun into place, and you smiled as you felt your nose snap, grow and sharpen into a proper, Mediterranean-like shape.
Andy was moving carefully now, working you into the final stretches'. You body convulsed, keeling forwards but Andy kept you steady though your bliss. Your abdomen now too bore a rich, six back and an Adonis belt that could slice and apple. Steady as anything, Andy squeezed your rod and you then howled.
A wave came crashing and you emptied your seed across your transformed chest. Layer after layer squirmed from you. Exhausted, you crawled upwards with Andy's help and looked at your body. You were built like a boxer, or perhaps a cage-fighter. Yet your arms were thick with muscle, and your thighs were thick like a sprinter. You were the same height, although your member hung at 12 inches in length with a pair of thick balls under them.
Despite the shagginess of your flesh, the hairy armpits, forearms, legs, the beard and chest... You glowed with a boyish charm, bolstered by the fizzing energy of youth. A young man with the will, energy and strength to wrestle a bull.
You looked at Andy and flashed a grin not all that dissimilar to the one Andy bore.
