You tired to hoist yourself onto your feet but the afterglow of your nightly emission, still a grim, glistening stain spattered across your groin and belly and thighs, tingled and itched across your flesh, your groin throbbing madder than ever with itching, heart-pounding need. You back landing flat against the cavern wall as you slipped backdown onto your bare buttocks, which felt sensitive and pleasant to the simple touch of the ground. You get out a guttural moan, something deep and satisfied as your body itched and tingled pleasantly. That consuming pleasant itch focused on your erection. Your eyes darted towards it, reluctant to stare at your needy member, outright terrified that you'd give into the consuming lust of the forest.
It began to grow, your heaps beginning to runt slightly as it did so, forcing you to clamber onto all forms to stop. Still, your hips thrusted back and forwards, beckoning you to give in. Last you checked, it stood erect at an above average 7.5 inches but as you watched it grew until it stood tall at 10 inches. That was almost the length of a ruler! You rolled onto your side, you heat pounding as you felt you balls swell larger again, growing hairy and mind-numbingly sensitive. They were filled with seed ready to launch, and continued to pump mighty testosterone though your changing body. By now the tawny completion had spread over your entire member and balls. That tawny color also colored your pecs, the hair that covered them spreading further over their surface. The hairs were dark and openly noticeable. Your thick and dark pubic hair had also began a trail towards your navel, but had yet to reach it.
Mark was awake now, having seen your change, his still thin-human form stained with sweat. He looked as if he were glistening...No! You shook your mind clear.
"You...oh fuck you had a wet dream..."
"Yeah fuck. We're so..." You stopped to let out a slight moan of delight as you adjusted your position. "God I want this to end..."
Mark nodded, his eyes still heavy but looking more refreshed than before. You looked outside, the sun beginning to rise. Another day, another chance to get out of here.
You still could pass as human. Mark was luckily unchanged, but the curse was getting to him... You heard him yelp in pleasured as his hand brushed past his member as he stood up and you eyes went wide with shock!
