He doesn't go to class

Kevin didn't go to class the next day, preferring to seclude himself in his room, fearing his new ability would cause chaos. After all, he still remembered the sudden change in the attitude of the girls around him, especially his conversation with Professor Richard.

"My God.... she almost **** me, she was ready to fuck me."

There was no doubt he had sexual pheromones; that was the only way to explain the cold professor's abrupt interest in him. He could even feel her breathing in his essence like a madwoman.

"One more second and I would have ended up with my pants down."

The fatty spent hours playing Pokémon Go, trying to avoid the constant erotic thoughts that had been running through his head all night.

It wasn't that he completely despised these changes; rather, he felt insecure about how to deal with them. He was quite out of his comfort zone. He had spent so long living a miserable life that he never thought he would get anything close to happiness.

Despite his awful situation, Kevin tried his best to be a good person, perhaps wanting to emulate his video game heroes or hoping that his life wouldn't get any worse... if that was even possible.

He understood how dangerous his unusual ability was. His mind imagined a million possibilities of what he could do. Having any beautiful girl crazy for his scent would open the doors to endless opportunities. He could have one-night stands, or maybe a serious girlfriend, and if he set his mind to it, he could be the master of a harem.

"My God.... This is fucking crazy!"

And to make matters worse, all the changes in his body had increased to ridiculous levels. His balls had swollen to the size of grapefruits, and along with that, a thirty-centimeter mast with the thickness of a baseball bat.

In addition, his body odor had become concentrated, even showing a faint pink mist coming from his voluminous skin, and his smell was three times stronger than yesterday, impregnating his entire room with a cozy air. Any attempt to remove it wasn't only unsuccessful; it was a joke. No matter what products he used to appease his pheromones, they prevailed with greater intensity.

Toc toc toc toc toc toc toc toc toc toc.

The senseless knocks on the door snapped Kevin out of his dilemmas and back to his failed life.

"Get your fat ass up, whale! I don't care if you're sick. I want you to clean my room!" Eva said with the delicate touch of an ogre in a rage.

"Uh.... but I... I," Kevin stammered, unable to explain his strange condition.

"What did I tell you, trash!? I don't give a shit about your girly problems now... MOVE!"

Heavily, he left his phone and moved his great mass from the bed toward the door. In his bad luck, his sister was still standing in the doorway, probably to continue her insults.

A tiny pajama covered the blonde's succulent body, leaving her perfectly shaved entrance in sight. Those masculine instincts that had become more persistent these last days came to life, pushing him to see her as the desirable female she was.

In fact, this was not to Eva's liking, who would rather hug a cactus than show a minimum of affection for Kevin. And so, her anger reached her unquestionable beauty, looking at her brother with sparks in her eyes.

"Grrr... you big ball of grease, how dare you look at me in such a repulsive way! You don't know how disgusted I am by you. I'm going to... Sniff... I'm going to... Sniff... to... to... Hmmm."

Eva stood still and speechless, as if her brain had turned off. She put a hand to her head, blinking several times. Then, excitedly, she looked at Kevin as if it were the first time she had ever seen him. A powerful impulse led her eyes straight to her brother's pronounced bulge.

The constant growth of his private parts made it impossible for the obese man to hide it. It looked like he was carrying two softballs and a small bat stuffed into his pants.

"Ugh... uh that... that... What is that?" she stammered, her eyes trapped on that abnormal bulge.

In turn, Kevin was getting more and more lost, seeing Eva's generous chest. He always knew about her great assets, but on this occasion, his hormones whispered to him how sexy and hot she was. A gift for the eyes with those curves, her perfect figure, and that smell of a female that gave him increasingly incestuous ideas.

He was so lost that he didn't realize when his sister suddenly stuck to him until he felt the softness of those tits. The scene he had with Margaret was repeating itself, only now someone of his own blood was starring in the encounter.

Then, their gazes met. The fat man's eyes noticed a changed Eva, a face as red as hell, glassy pupils to the point of tearing up, and a lost gasp.

"Ooh.... ohhh what do I see.... Sniff Sniff.... Besides being a nerd and fat, you're also a perverted pig who.... hmmm... gets turned on by his hot sister's body ooooh," she said, on the verge of moaning.

"No... uhh... it's not what you think.... ooooh."

Kevin's poor excuses died when he felt a hand squeezing the package in his pants. Crushing his bulging testicles, Eva's fingers measured the size of her brother in a rude way.

"OH FUCK, IT'S HUGE!..... Sniff Sniff...... damn it, Whale, you're such a pig that your balls are about to burst with so much semen.... mmmmh.... yes, abundant and thick semen... Ooooh... semen that's ready to dirty the inside of a female."

"Ugh.... uh.... uh.... hey Eva.... I need... I need to clean."

Those words provoked a new change in Eva. First, she stopped dead in her tracks, and then she looked at Kevin, super confused, as if she had forgotten who he was. With a groan, she detached herself from the nerd, closing her eyes in shame.

"I... I.... go... go away at once.... And don't tell anyone about this!" she said hesitantly.

He obeyed, running away from there. Looking back, Eva was hugging herself tightly, unsuccessfully containing the intense trembling that embraced her body, and he noticed a liquid running down her legs.

There, Kevin confirmed the reach of his pheromones. After all, if his hateful sister was getting wet for him... what else could he do?.

Note: I'll be giving this story a little break to work on others... thanks.
