Chapter Text
In the secret lab of the dread doctors, there was a special “potion” that caught Theo's attention. When the doctors were alive and the chimera had an alliance with them, the young man would analyze the chemicals and the other stuff that the doctors used for their experiments. Some were very dangerous, others disgusting, and finally, there were these jars filled with a liquid that guaranteed an effect that got Theo very interested in them. The young chimera found a “potion” that, according to the label, had the effect of increasing the sexual desire and muscle mass of the man who drank it.
All of this in exchange for his intelligence. It was basically a formula that could create the perfect himbo. Theo talked about this with Liam, who had become the only person who trusted him after everything that had happened with his evil schemes. The young chimera wasn't someone you could trust, but this plan he had formulated with Scott's young beta seemed very good and should be used on a certain hot alpha. They were talking about Derek Hale, who, despite already having big pecs and a very appealing round ass, could get even hotter.
Now they were inside Derek's loft, finishing their private training session with the green-eyed alpha. “Your efforts were good, but your young bodies should get used to these workouts faster,” Derek said as he walked over to where he had put his water bottle. What the oldest of the three didn't know was that while he was training with Liam, Theo had poured the “Himbo Potion” into his water bottle. Knowing what was about to happen, both boys watched intently as the alpha werewolf drank the water mixed with the liquid.
The two young men watched him drink the water, causing Derek, somewhat confused by their eager gaze on him, to turn and look at them. “Is something wrong? ...Do you guys want some water?” the werewolf asked, but unfortunately for him, the liquid they poured into his water bottle began to take effect. It caused him to feel a strange twinge in his head. Sooner than expected, he began to feel dumber, and looked confused as his pecs grew larger, almost as if they were a woman's large breasts. In addition, his glutes also became bigger like his pecs.
“Damn, it's really happening,” said Theo, surprised to see how the black-haired man was transforming, and not into a werewolf, but into the perfect himbo they wanted to use for their erotic fantasies. As was previously established, Derek already had a round and appetizing bubble ass to begin with, plus he almost always wore tight jeans that accentuated that delicacy. Now, those buttocks were growing so much that they ripped his pants apart. They also stretched his underwear, and those buttocks kept growing like the huge cocks of these mischievous young men.
It was impossible for the two boys not to be turned on by the strange but exciting scene unfolding before them, especially Liam, who said, “What surprises me most is that the dread doctors had something like this in their laboratory.” Theo also found it strange that they had developed this “himbo potion”, but he was going to restrict himself to just thanking them in his mind. The moment Derek's buttocks and pecs stopped growing, he turned to look at the young men and asked, “...What just happened?” to which both boys just turned to look at each other and smiled wickedly.
“Nothing. Nothing happened, Derek. You are probably feeling confused about the… the training we had.” That's what Theo replies, while Liam just keeps his hungry gaze fixed on Derek's big tits. “...I see, that makes sense ...but now I feel a little ...naked.” Derek Hale was now just a big hunk, a big, sexy hunk who was so dumb that he accepted that answer. “I think you should stay like that. I'm sure it'll be more comfortable for you.” Raeken continues to approach him, marveling at how Derek's underwear could barely contain those huge globes of flesh.
Those asscheeks were so huge, and they needed to have an equally large cock between them. “It is nice to be like this. I really feel more comfortable without clothes... it doesn't bother you guys, right?” asked Derek, who was already taking off his underwear and stretched T-shirt. Obviously, they both said it was no problem. “No, not at all,” said Liam with a big perverted smile on his face. It didn't take long for either of the boys to start taking advantage of the werewolf, who was nothing but a horny, stupid piece of meat for their enjoyment.
Both boys had an enormous desire to eat that ass, burying their faces in that big bubble butt and running their tongues over that hairy hole. Hairy like the rest of that big, beefy body he had. That seemed to excite the two boys, who, having that dumb stud in front of them, decided to enjoy everything he had to offer. “Oh, look at these huge tits, Theo, aren't they lovely?” asked Liam, who had his hands on the now larger pecs. “Of course they are, Liam, they're too juicy and sexy to be ignored, isn't that right, Derek?”
Derek didn't answer; only unintelligible horny sounds came out of his mouth. What happened next was that the black-haired hunk was now lying on the floor. In this position, Liam undressed himself and began to play with Derek's man-breasts while rubbing his erection against Derek's. Theo, for his part, decided to sit on the face of the big, bad werewolf, who was now his submissive and stupid himbo. Well, not so stupid, because he got the message and started running his tongue over Raeken's hole, who was enjoying the wet licks from the black-haired man.
“Oh yes, alpha, do it like that... my stupid himbo,” moaned the naughty young man, noticing how the young werewolf continued to run his hands over those huge man-breasts. He was also rubbing his naked erection against Derek's hard cock. Dunbar couldn't take his hands off those tits that used to be normal male pectorals. Still, there was no denying that these tits were so fucking juicy, so much that Liam loved to knead them with his hands, squeezing them hard, just as he squeezed the nipples, hoping that milk would come out of them.
With his fingers, he pinched those delicate nipples, while with his other hand, he simply ran them over Derek's now large chest. It was hairy, really soft, and it felt hot to do this to a man who was so handsome. Theo, for his part, masturbated his cock while continuing to feel the hot, wet tongue of the poor himbo on his asshole. Derek could do nothing more but sexually pleasure him. He couldn't resist the sexual desire that was now more than present in his body and was making him do this. “I can't resist any longer, I need my cock between those two huge man tits of yours.”
Liam couldn't hold back his urges any longer, so he decided to get straight to the point, to do what he really wanted to do. Bringing those two gigantic, juicy, hairy breasts together, Liam slowly began to fuck them with his thick cock. He forced his way between those two mountains of meat, but didn't let them separate. Moving his hips, he was pretending to thrust between those two magnificent tits. Liam felt hornier than ever. It wasn't the pleasure of fucking a tight hole, but the sensation of friction felt good anyway. He was fucking the werewolf's tits, so hairy, soft, and sexy.
He couldn't stop watching his cock grind between those two big pecs. As for Theo, who was still sitting on the older man's face, he finally decided to get up, leaving the man with nothing covering his face, but maybe that was for the best, since Liam didn't seem like he was going to be able to hold back any longer. “Oh God... oh... I'm going to come... I'm going to... fuck!!!,” Liam moaned loudly as he released his large load of white cum. That large load ended up staining the himbo's meaty tits, and it also reached the face of the big bad dumb wolf.
That was undoubtedly one of the best images either of the two horny young men had ever seen. It was Derek Hale, covered in several streaks of hot cum on his face, and some even made it into his mouth. To top it all off, the himbo stuck out his tongue to catch the rest of the drops of white seed running down his face. “Oh hell, this was better than I expected. To be honest, I didn't expect much from that potion, but if we turned Derek into our muscular bitch, then we could use it with the other wolves in the pack.”
Theo began to think dangerously and wickedly, but Liam stopped him. “Hey, calm down, we don't want everyone to realize what we're doing. We'd better be careful with this thing.” Then the chimera reasoned and nodded. “Well, okay, but in the meantime, let's continue enjoying this pretty cock slut.” Then, both boys were surprised to hear the new himbo whore Derek begging for their cocks. “Yes, please, give me more cocks, please.” Not only did they make Derek stupider, but they also turned him into a total horny slut who lived for cocks.
“Well... if he's begging so much, why not give it to him?” And with an evil smile, Theo suggested to Liam that they should fuck Derek at the same time. Liam, being the horny young man who didn't care about anything but burying his cock in a tight, hot hole, agreed to that idea. Their cocks quickly became hard, with Theo having a huge load that he wanted to pump into the werewolf's hairy hole. Theo lay down on the floor, letting the big hunk get on top of him. Theo certainly loved having his hands on Derek's fatter ass.
And the big black-haired wolf was getting used to the thickness of that piece of meat. “Oh... your cock is... so... thick... so long,” Derek said between sighs and little moans of pleasure. “A thick cock for your... fat ass... mmm, it's so big. I love this ass, but I'm sure Liam would like to join in, wouldn't you, little man?” At that question, Liam joined in, sticking his dick in Derek's ass. “I may be smaller than you, but my dick is bigger and thicker than yours. I'm sure as fuck that Derek likes my cock better than yours.”
“Ha, what do you say, Derek himbo?” Theo asks the black-haired man, who was moaning with pleasure at having two fat cocks shoved inside his tight, hot interior. “Cocks... I love... both of your cocks... oh yes,” That was the moment they unlocked the dirtiest side of that hot werewolf. Their thick cocks stretched Derek's anal walls in a painful but equally pleasurable way, and the pleasure of feeling such a tight hole was incredible, especially when feeling their two cocks rub together. The point in the end was to enjoy how tight it was and make a little more friction for more pleasure.
Derek was moaning like a damn bitch in heat from the sexual bliss those two huge cocks were giving him. Now he belonged to both of them... and maybe to anyone who wanted to fuck him. Liam and Theo kept fucking Derek until they came inside his ass, filling that hole with two huge loads of warm cum that flooded the man's rectum. After pulling out of that ass, Liam and Theo told their new himbo slave to start twerking in front of them. Nothing better than enjoying how that big, bad, dumb werewolf shook his ass for those two horny young men.
