Joseph figured he could just go ahead and leave Mark to take care of the other chores he had been due to deal with, after all, they were just about done anyway. And he was not feeling up to finishing them off in this heat when he was apparently having a problem. He'd never known himself to have heatstroke problems, but Joseph didn't know what else this could be but heatstroke. He simply laid there on his bed, waiting for the temperature he was feeling to go down. But if anything, instead, he would find himself feeling a new sensation even as the heat seemed to enter into a strange pulsing phase.
A moan came from Joseph's mouth involuntarily, before he could even stop himself, as he felt his manhood tingle in his boxers, twitching and pressing against his boxers. He thought the more sensitive, sexual years were past, when he could just deal with life as it came without being immediately sidetracked by his needs, but he was evidently wrong. Joseph hoped nobody came in here and saw him like this. It'd be massively inconvenient and embarrassing...
Joseph moaned again and shifted on the bed even as he shifted in other ways as well. His formerly lightly hairy chest started to develop more, his pectorals pushing out a bit more, his abs tightening and pushing out a little bit more. His hair started to thicken on his chest as well, becoming impressive looking further down and producing more leading up to his chest. His arms ached a little, making him gasp as he tried to stretch them out, which eased the ache even as his biceps and triceps bulged a bit with new musculature and hair started to grow in thicker.
The 30 year old was having trouble keeping his hands off of himself, and nothing else seemed like it would alleviate his heavy, hot sensations. "I-I can partake for now..." Joseph said to himself, trying for a justification, "No one's gonna come in...I'm gonna be by myself enough...ooh yeah..." He hooked the side of his boxers with his thumb and pushed it down even as his pubic bush thickened somewhat more.
The feeling of Joseph wrapping his hand around his growing manhood almost made his hips push up from the bed, his teeth immediately grit tight, and he slightly kicked with one leg. With one hand wrapped tight around his suddenly sensitive manhood, Joseph began pumping it, groaning as he felt something seemed to be different. He hardly even noticed that it was his legs, thickening and muscling up even more than before. His toenails on his feet starting to toughen and darken...
Joseph stopped for a moment and bit his lip, pulling a blanket over himself as he heard a knock at the door. "Who's...who's there? I uhh, I'm busy."
"It's Kathy."
Oh, that does explain a few things, Joseph sighed and resigned himself to having to pause his fun in order to deal with his sister. His erection still pulsated in his hand, and he asked, "Is...there a problem, Kathy?"
"Mark was being mean to me again. Can you please---"
"I'll talk to him, okay? I'll talk to him, I'll talk to that fuc---brother of mine." He said in a hurry, even though he had no intention of doing so, and he felt relieved when Kathy's footsteps left the front of his door and then down the hall. He threw the blanket off of himself and merrily returned to what he was doing.
Joseph was really feeling it today, which probably could be explained decently well by the fact that even as his distraction occurred and he covered himself up, his manhood had changed a fair bit. The foreskin had returned and the whole thing was just a bit larger and more sensuous. Barely even noticing the changes so far, Joseph kept going on himself...
