Melissa and Mei were at Central Hospital. The two girls had been tasked to study the Nomu defeated by All Might. Though they weren’t performing surgery, they still wore surgical scrubs while their regular clothes had been neatly folded nearby. The creature had been restrained and put on an operating table. Despite it’s bound and unable to move, the two of them were clearly more than a little nervous.

“So this is the creature that fought with Uncle Might, huh?” Melissa said.

“It sure is!” Mei said. Melissa looked at her. She couldn’t be sure if the girl’s exuberance was genuine curiosity at the creature or a way of covering up her nervousness. They had been told that the creature was completely docile and wouldn’t hurt them. But they had a hard time believing that when it was just the two of them alone with it’s clearly inhuman appearance even compared to some of the more eccentric heroes out there.

“Okay, so let’s get started,” Melissa said. She touched the creature’s torso several times, wanting to see it’s reaction. It winced a bit, but she paid it no mind. “Do you see anything out of the ordinary?”

Mei had activated her quirk as soon as the creature was rolled in here. She looked over it, scanning it’s body for any physiological reactions. Her superhuman eyesight allowed her to every pore on it’s skin. Though her cheeks tinged a bit when she saw a faint stirring in the crotch of it’s pants.

Melissa didn’t notice it at first, she was too busy touching all over the rest of the creature’s torso. But it struggled against it’s restraints. Mei was too busy staring at the penis stirring in it’s pants. Melissa didn’t notice it though, and she didn’t stop prodding all over it’s naked torso either. She felt no fear in doing so, the restraints clearly had it down for the count and it was true what they were told about it being docile. Despite it’s fearsome appearance and the two girls being left alone with the monster with no other heroes on duty, she didn’t flinch once. Though when she looked down, she finally got an eyeful of it’s boner too. And it was standing up at full attention through it’s pants.

Despite being a monster, it’s still just a guy, she thought to herself.

At first, she ignored it. She kept on poking and prodding over it’s torso, gauging for any abnormal reactions. There were none. Mei’s quirk was activated the whole time, and she even looked at the creature’s head to see if there was any change in it’s brain chemistry while Melissa was poking at it. There were definitely some changes there, but she couldn’t make heads or tails of it.

When Melissa was done, there was an awkward silence. “Alright, I think we should look at the rest of it,” Mei finally said, looking at it’s bottom half.

“Um, o-okay...” Melissa said nervously. For several moments she just looked at it’s penis standing up against the tightness of it’s pants. She didn’t know what to say at all.

As the two girls kept on looking, the member started twitching even more. “Wow, it sure is big!” said Mei. She smiled to herself. “You want to see what else it can do with that?”

Melissa looked at Mei. “You mean...?” she said, her voice trailing off.

“Yeah, I do!”

Melissa looked back down at the creature again. She couldn’t believe that something so docile could have ever been a challenge for someone like All Might. Though it getting hard for wasn’t so shocking, a girl as shy and well endowed as her definitely got more than a few unwelcome compliments. But as she looked over it’s muscular torso and it’s big dick, she did feel a perverted longing in her body. She wondered if it would do anything she wanted it to do to her.

Melissa nodded and smiled. “You’re right. We have to look over everything. It’s for research purposes!”

“Yeah, research!” Mei chirped along. But she was so loud and enthusiastic that she could have been saying anything. She knew exactly what she wanted.

Melissa cracked her knuckles before she went to unbutton the Nomu’s fly and zip down it’s pants. Her hands were shaking with excitement, she couldn’t believe she was actually going to be doing this. So it took her a fair bit of effort to actually complete the task before her.

Mei also watched with fascination, giddily smiling the whole time. She was using her quirk to watch the scene play out before her, studying the tensing bulge wriggling in the pants. As Melissa was almost done getting the pants down, Mei couldn’t help but notice that the other muscles in the Nomu’s body were also tensing up.

The moment Melissa got the fly undone, the creature’s penis sprang right up. Melissa’s head was so close that the member almost hit her right in the face. But the quirkless girl was quick enough to avoid that happening. Not that she didn’t stare at it for several moments though.

“Wow...” Mei said in a flabbergasted voice. Though she was calm compared to her usual outgoing demeanor, anyone else using that tone would have still been labeled as lively.

“We should probably get the rest of it off too,” Melissa said, looking down at the pants. Then she looked right back at it’s dick. Despite being a homunculus, the penis was a dark red in contrast to it’s black body, clearly it’s blood pumped just as well as it did in life.

“You really wanna mess that thing up, huh?” Mei said. Melissa looked back at her. Her friend had a naughty grin on her face.

“No, it’s purely to help the heroes and determine just what these things are!” Melissa said trying to save face, though they both knew it was a lie.

“Alright,” Mei said with a sneaky grin. As Melissa was still gawking at the member still pointing up, the other girl grabbed right onto the shaft. The Nomu jerked up hard at that instant. “Wow, it’s so big and hard,” she said, stroking up and down the shaft. She was using her quirk just then too as she looked at the penis. Her power let her observe the changes in it’s penis at the atomic level with her naked eyes. But more than that, the dick was already so big on it’s own that her whole line of sight, even her peripheral vision, was filled with the red and pulsing dick.

Melissa forgot all about getting it’s pants off. She knew what she was going to do was wrong, but she was so jealous watching Mei like that. She wanted to get a feel for it too, just to see how else it might jump up. And on the practical side, she heard that this thing had quirks designed to take as much punishment as possible. A naughty side of herself wondered if that extended to this particular part of it’s body. So she grabbed the cock head.

That did it. The Nomu started moving around a bit more, grunting through it’s beak. Melissa was so surprised that she instantly stopped playing with the sensitive tip of the monster’s penis. Mei on the other hand wasn’t put off at all and instead increased the rate of her hand job.

“Come on,” Mei said, looking up at Melissa. “You’re acting like you’ve never seen one of these before. Don’t you wanna see what this thing can really do?” She even put her face right up to the shaft and lewdly sniffed it before she closed her eyes and sighed happily to herself.

Melissa realized she wanted in on that too. She grabbed the hem of it’s pants and worked on getting the Nomu’s clothes down it’s legs. It was a bit more difficult than she expected, the whole time Mei was beating it off.

The Nomu was squirming on how good and soft her hands were on it’s naked penis. It got way more animated after that. It was made to only take the orders of villains, but even it couldn’t resist two pretty girls playing with it’s meat.

Mei watched Melissa while she still stroked it’s dick. Even as Mei stroked it’s cock, she wondered why her partner was taking the time to get it naked instead of getting in with the big dick that was completely exposed already. But when the pants were down to the Nomu’s ankles, she understood why. Looking right over at Melissa, she watched the blonde girl dip her head down so her face was right next to it’s testicles.

The sack was already fully engorged with arousal from Mei’s handjob. Melissa got a whiff of the scrotum and closed her eyes, sighing dreamily to herself. And when she first licked it’s balls, the Nomu actually opened it’s beak and cried out.

It grit it’s teeth as it struggled against it’s restraints. There was no longer any question that it was acting of it’s own will now. Though neither of them could tell whether it wanted to break free or that it was just thrashing around from them messing it up that good.

Both girls started giggling. It was reacting exactly like they hoped. Melissa licked it’s nuts again, now taking her time to mash her tongue right up against the swollen sack. She felt it’s hot balls twitching right up on her tongue and moved her head to lick at the base of the shaft as she slurped up the sack. At the same time, Mei fully took the shaft in her mouth.

At first she didn’t know how to respond, the giant meat was so large that it almost made her gag. But she eventually found a pace to her blowjob. She slowly sucked on the cock head for almost a minute before she began taking in more of the shaft with each wet suckle from her lips. Despite it’s size, she bobbed her head up and down on the erect member in no time at all, loving just how badly the hot meat was throbbing in her mouth.

While Mei was sucking dick, Melissa took the whole sack into her mouth too. With it’s large nuts in her mouth, she found herself struggling a bit like Mei did earlier with it’s cock. But watching Mei get a feel for it, she emulated her partner. To her surprise, blowing the Nomu’s nuts like that worked just as well. She moved her head back and forth, moaning sweetly, taking in the heat of it’s genitals and feeling each of it’s balls plumping up on her tongue.

The creature was thrashing all over the place and yelling out like an unruly pet getting it’s shots. Yet neither of the girls stopped giving their affections to the Nomu. They also helped hold down it down, Mei holding down the torso and Melissa grabbing it’s hips. Even though neither of them were that strong, especially compared to the muscular brute under them, it was only squirming from it’s dick getting messed up and wasn’t aiming at anyone or anything. They still didn’t feel in danger, but they loved dominating such a large creature at the same time they were lording over this dick.

Suddenly it grunted louder than ever before it’s cock tensed up in Mei’s mouth. She was already down with the shaft a good ways on her tongue when she felt several blasts of it’s hot semen shoot right on the roof of her mouth. The ejaculation was so sudden and violent that before she could work to swallow it, she was hit with another spurt, and it was all so much cum shooting into her mouth at once that it went right down her throat. There was more too, the copious amounts of semen gushing inside her was so much for her that at first she almost choked on it. She took the dick out of her mouth to make it easier only for it spurt several more shots of cum right on her face.

Melissa had been going down on it’s nuts the whole time that was happening. She felt the immense sack bloat on her tongue at the moment of climax and then spasm multiple times when it jizzed down Mei’s throat before it diminished in her mouth. She knew it just came, both from the sensation in her mouth as well as the commotion with Mei right above her. But she didn’t take it’s testicles out her mouth at all, instead she just kept on nursing the Nomu’s nads as it’s dick kept on wildly cumming all over the place. And as it jerked wildly all over the place, some of the jizz from it’s spurting cock got on her blonde head of hair.

When it stopped cumming, the creature calmed down, becoming inert again. Mei’s face was soaked in the sticky white stuff. She was so cum coated that she even saw some of it dripped right off her eyelids. She took the chance to wipe the cum off her face and lick off every bit she could.

After that, Melissa took the nuts out of her mouth and went down on it’s penis this time. There was still a good deal of semen still oozing out the opening of it’s prick and the blonde girl made sure to swallow every last drop she could. While she did so, she also started sucking it off beyond cleaning up the rest of it’s cum, wanting a taste for herself.

That strong nut at from two pretty girls sucking it off had left the Nomu feeling amazing, way better after all the fighting it was trained to do and then doing nothing while in the custody of the heroes. So Melissa’s loving treatment was just heavenly. All it could do was sit back and take it all in.

But it didn’t remain still for long. It’s quirks of superhuman endurance weren’t just for combat, and it was quickly getting hard again. Melissa’s loving treatment was getting it hard again even as she just used her mouth to fully clean up the massive shaft of excess cum. It had been easy for her to suck it off at first, yet the speed at which it’s dick was getting erect surprised her, and before she knew it, the cock head was right up at the roof of her mouth.

She had to take the phallus out of her mouth to breathe. Mei got down on the other side of the table so both girls were on opposite ends of it’s penis. By now, her face was clean of cum but there was still a faint shiny residue of the spooge left on her beautiful features. Melissa was about to say something before Mei winked and pulled up her shirt, revealing both of her tits. She leaned forward and wrapped her ample bosom around the shaft of the Nomu’s penis.

Melissa didn’t want to be left out. She quickly took the hint and followed Mei’s lead, taking out her breasts too. She leaned forward so that the Nomu’s penis was completely consumed by two pairs of big teenage tits. The two of them quickly giggled, enjoying the feeling of the hot shaft in between their massive hooters.

“It’s so big!” Mei said.

“It sure is,” Melissa said. This time, she smelled the penis. “And it smells just as good as it’s balls.”

Mei used her quirk and got a good look at it’s penis again. “It’s molecules are changing and it’s getting even bigger! I think we should do make it cum again to see if anything else happens.” She gave off a naughty smile and licked her lips.

Melissa nodded, grinning herself. “Yes. We must do more research on it’s quirk abilities!”

As they were busy tit fucking it, their chests were also rubbing up on each other too. Plenty horny already, their nipples were hard and erect. They were so liberal with pleasing the creature together and their chests were so developed, big enough to make any dick love it, that their caps were rubbing up on each other the whole time.

But they were surprised to see just how much their fertile tracts of land had enveloped the dick. Having both gotten a taste of it, they knew the Nomu’s penis was big and long all over. Yet with their tits wrapped around the long shaft, there were only a couple inches of the shaft and the whole cock head left visible. Not that they minded. The considerable size and heat of the member felt great on their naked skin and they both loved how easy it was to dominate this cock again.

Melissa took the lead this time. She licked all over her side of the penis, over the shaft before she focused on sucking the sensitive opening on the tip. Mei liked that idea already and joined in, licking and sucking all over the shaft while licking the crown of the head every now and then. Contrary to how active the Nomu was before, now it simply relaxed, content to let both girls work it.

As Mei and Melissa were servicing the monster, licking over the shaft and the very sensitive tip of the member, their tongues met with each other more than a few times. Neither of them could tell who did it first, but eventually the both of them lost their composure and were fully licking each other’s tongues as much as they were slurping up and down the penis. They loved the feel of their soft lips and wet tongues on each other, but what they liked even more was the lewd taste of the Nomu’s penis fresh in each other’s mouths. All the while they still worshipped the thick penis. Though after awhile they actually did stop sucking dick just to fully embrace and make out with each other for several minutes.

The Nomu just watched. Their tits felt great on it’s shaft and it loved watching them go at it. After that strong nut earlier, this kind of treatment was divine and even in it’s primitive brain, it looked forward to what else might happen today. If it’s arms weren’t still bound by restraints, it would have smugly put it’s hands under it’s head and watched the show.

The two girls stared lustfully at each other with a long trail of spit between their tongues. “So apparently it’s cum makes one extra horny,” said Melissa as she licked her lips.

“It sure does!” Mei said, and this time pulled Melissa in right for a direct smooch on the lips. The two girls sucked face for another minute, forgetting all about the big dick enmeshed in their titties.

Not that they could ignore the penis for long. They felt it’s dick thickening again in between their breasts. They broke the kiss, not to stare at each other again, but to look down at the cock nestled between their titties.

They licked up the sides of the shaft again right up to the head. Then they would lick back down, then back up, over and over again. This time both girls felt it move, what with how they were both tit fucking it and eating it’s penis in equal measure. They didn’t stop though, they were eager to drive it to it’s limits and feel it’s cum all over again.

The dick was twitching more and more with each passing second. But then it’s cock suddenly erupted, blasting jizz all over the faces of both of the girls. The Nomu was so horny that it’s dick kept on cumming, and each spurt was so powerful that as it’s semen reached as high into the air as it could, it practically rained back down on the girls’ heads. They both laughed and looked up with their tongues out, ready to catch as much cum as they could. They made sure to savor the taste and texture of the cum as they did so. All the while, their hair and faces were being showered with the monster’s sticky white stuff.

When it was done cumming, they both looked at the Nomu’s dick again. They were impressed that it wasn’t softening one bit and felt it get bigger in between their tits. The penis was still releasing a little bit of leftover cum. This time, they both took turns licking the cock, cleaning up every spurt of it’s thick substance. Once they were done, they both looked into each other’s eyes and made out again.

Their kissing session lasted a little longer this time. They pressed their tits up against each other and moaned deeply, savoring the taste of the Nomu’s cum in addition to the flavor of it’s penis. They also made sure to rub their sensitive nipples up against each other. When they stopped, Mei giggled at how Melissa’s glasses were falling off and properly set them back on her face. Apparently she had gotten so into it that they had fallen off a little bit.

“So the cum tastes the same,” said Melissa.

“It sure does!” Mei said, closing her eyes and smiling as she closed her eyes and licked all over in her mouth. Then she looked down at the penis. She didn’t even need to use her quirk to see that it was just a little larger now. “But it’s also getting bigger.”

Even with Melissa’s faulty eyesight compared to Mei, she could see that too. “Clearly it’s quirk of regeneration extend to areas beyond fighting. I think we should step things up a notch.” Just as she had gotten it’s pants down, now she worked on undoing the restraints. Mei looked at the Nomu again, her quirk was still activated. She was watching it’s skin closely, observing it’s muscles tensing up as her partner was working on getting it free.
