Chapter 4: Summertime Sexcapades

Soon enough, the school year had ended. In a month, Classes 1-A and 1-B would become 2-A and 2-B. During that time, some students would study. Some would goof off. And as for the threesome of Eijiro, Mina, and Itsuka? Well, this would be their first summer together.

"Ha!"

"Ya!"

At the moment, Eijiro and Itsuka were in the midst of a sparring session at a dojo the orange-haired girl often frequented. While the three still met up to work out, Itsuka suggested that Eijiro and Mina could do with learning some martial arts. Especially Eijiro, who the teal-eyed girl suggested would be a real threat if he combined his hardening quirk with a genuine fighting style.

And so, the two combat enthusiasts continued their spar, sweat flying off their muscular bodies as their fist and feet moved with swiftness and purpose. Eijiro threw a punch, but Itsuka managed to grab her boyfriend's arm and toss him onto the mat.

"Dammit! You are way too good at this." Eijiro said, catching his breath as he sat up. Itsuka sat next to him, wiping some sweat off her brow.

"Well, I have been training since I was eight." The orange-haired girl said. And maybe it was the sunset reflecting off her orange hair, making seem positively radiant, but Eijiro was once again mesmerized by her.

"Itsuka, you're stunning." The redhead said, making his girlfriend blush.

"Geez, where did that come from?"

"I dunno. It just felt like the right thing to say." Eijiro replied with a toothy smile. Itsuka looked at her boyfriend. And that smile in combination with the sweat glistening off his shirtless torso was making her feel all warm.

"You big dork." Itsuka said before closing the gap and kissing him on the lips. There was no one around them, except for the manager at the front desk, hence why the embiggening girl had the confidence to kiss her boyfriend so suddenly. And it started off as just a sweet and tender kiss...until Eijiro kissed her back harder, and she felt his tongue rubbing against her lips. Without hesitation, Itsuka opened her lips, their tongues soon rubbing against each other.

Maybe it was the sweat, the sunset atmosphere, or their current loose clothing (Eijiro wearing just some workout shorts while Itsuka traded in her usual sweatpant for black shorts), but the muscular couple began to feel more and more amorous with each passing second, with Itsuka pressing her body up against Eijiro's, wrapping their arms around each other as they continued to french kiss. The two could feel each other's muscles rubbing together, Itsuka's bosom pushing against Eijiro's chest, and their hips touching.

Soon, they had to break for air, a small string of drool connecting their lips as they looked into each other's eyes. Pools of red and teal were absolutely shining with lust. Not to mention that Itsuka could feel Eijiro's crotch growing underneath her.

"Hey, Eiji?"

"Ya?"

"C-Can...can we go to your place?"

The young lovers were quick to leave the dojo, every moment taken heading towards the Kirishima residence filling them up with more and more anticipation. One thought was clear in both their minds; today, they were going to go all the way.

The two reached the Kirishima house. After confirming that his parents weren't around, the couple went up to Eijiro's room. And as soon as they entered his room, Itsuka pounced on him, wrapping her muscular arms around his torso as he closed and locked the bedroom door.

When they were down with their next make-out session, the two separated and began to strip down. Eijiro removed all of his clothes, pulling down his boxers to reveal his ten-inch cock, hard and ready for action (Itsuka letting out a squeak when she saw how thick it was). Itsuka stripped out her own clothing, removing her panties to show her clean-shaven and moist womanhood, and then took off her sports bra, her D-Cup breasts and light brown nipples held up by a firm set of pecs.

The two took in the sight of each other naked, seeing each other's firm bodies only adding to the arousal. Eijiro approached Itsuka and kissed her again, lifting her up by her glutes and placing her on his bed, the redhead landing on top of her. But as they kissed, a thought popped into Eijiro's head.

"Um...I don't have any protection."

"It's okay." Itsuka said. "Mina and I thought it would be a good idea to get on the pill incase...well, something like this happened."

And so, the muscular lovers continued to kiss and press their bodies against each other. Eijiro soon reached and grabbed Itsuka's breasts with hands, marveling at one of the only soft parts of her body as he kneaded them up and down, making his girlfriend moan. In response, Itsuka reached down, touching the tip of her boyfriend's dick before wrapping her hand around the shaft and moving her hand up and down. This shared groping went on for a bit.

"I-Itsuka...can I…"

"Go ahead." The orange-haired girl said. And so, Eijiro lined his cock up against Itsuka's womanhood, pressing the tip against her vaginal lips before he began to push into her. And even though Itsuka's hymen had been torn from training before, the feeling of something pushing against her insides felt weird to the teal-eyed girl. As for Eijiro, he had grit his sharp teeth because of how tight Itsuka's pussy muscles were.

"Are you okay?" Eijiro asked.

"Ya. Just...just move slowly first, okay?"

"Got it." The redhead said, pulling his dick until only his tip was still inside her before pushing the rest back in. Each repeating motion made Itsuka moan. First out of discomfort. But to her surprise, that soon went away and began to feel good. Really good. And Eijiro was blown away by this sensation too, his hip movements becoming gradually faster.

"Eiji…" Itsuka said, wrapping her thick legs around her boyfriend's waist and her arms around his neck. "...harder. Fuck me harder."

And with that go ahead, all caution was thrown into the wind as Eijiro slammed his hips against Itsuka's, pushing his member harder and faster into her. The two teens moaned like crazy, the bed underneath them shaking along with their motions. As they fucked, Eijiro felt his girlfriend's pussy become tighter and tighter, encouraging him to keep plowing into her. In their minds, the two were blown away by just how good sex felt, and they now realized why their more perverted classmates were so obsessed with it.

Soon, the pleasure was too much for Eijiro, and he ended up climaxing inside of Itsuka, coating her insides with his seed. The sudden warmth caught the orange-haired girl by surprise, leading her to cry out as she achieved her own orgasm. In the afterglow, the two laid next to each other, Eijiro's member slipping out of Itsuka, his seed flowing out of her womanhood. The two looked each other in the eyes, passion overwhelming them.

"I love you." Itsuka said without any hesitation.

"I love you, too." Eijiro said before kissing her on the forehead. The two now felt closer than ever...but also realized that they should probably shower and clean Eijiro's sheets before his parents got home.

The next day…

"YOU GUYS FUCKED?!"

"MINA!" Eijiro and Itsuka shouted, the pink-skinned girl apologizing for shouting in public. The three were currently on a date in an outdoor cafe, and the two had just finished telling Mina about what happened yesterday. Soon, Eijiro went to grab their drinks from the soda fountain, leaving Mina and Itsuka to talk amongst themselves.

"So, how's Eiji's equipment?" Mina asked as she whispered to her girlfriend. "Is he big? Wide? A grower? A quickshot?"

If it wasn't for how lewd the questions were, Itsuka probably would've found Mina's curiosity amusing. Still she answered by holding her hands up to show ten-inches, making Mina's black & yellow eyes widen.

"He's also really thick and hard. And that stamina for fighting translates really well."

"Damn." Mina replied, a shiver being sent up her spine. The pink girl turned to look at her boyfriend and licked her lips, almost making Itsuka burst out laughing by how thirsty the pinkette was. At that moment, Mina made a mental declaration; the next time she and Eijiro were alone together, she was going to jump his bones.

Luckily for Mina, she didn't have to wait long. Two days later, Itsuka needed to help her classmate Tokage with some studying, leaving Eijiro and Mina to chill and watch movies at her place. While Mina's family was around, the two marathoned some horror, horror comedies, and romance movies late into the night, staying up far longer than Mina's parents and little brother.

Of course, Mina decided to put her 'get lucky' plan in motion by spending most of the evening sitting in Eijiro's lap. Especially since the only clothes she decided to wear were a dark pink t-shirt and her favorite purple panties. At first, she got some enjoyment when Eijiro's cheeks matched his face. But as the night went on, the two found the position turning comfy, with the redhead wrapping his arms around Mina's waist and the pinkette pressing her back against his chest, finding it oddly warm and cosy.

However, things took a turn when the romantic comedy they were watching suddenly turned...explicit. It wasn't too graphic, but the actors in the movie were really convincing and passionate.

"Woah." The two said as they saw the actors strip. The muscular pair were mesmerized by this sight. The movie cut away before actually showing anything, but the damage was done, as suddenly, Mina felt her boyfriend's cock growing hard and pushing against her panty-clad ass.

"My, my." Mina said, rubbing her ass against Eijiro's jean-covered cock. "Someone's definitely excited."

"Well, I just watched someone erotic while my sexy girlfriend is sitting on my lap. How could I not get excited?" Eijiro said before kissing Mina's neck, a light moan escaping the pinkette's lips.

"Oh, when did you get all smooth?" Mina asked before pausing the movie, turning around and kissing her boyfriend on the lips. And just like what happened with Itsuka, the kiss soon turned erotic as the muscular lovers added their tongues into the mix. They also continued to rub against each other, Eijiro feeling Mina's pussy getting wetter as she rubbed against his crotch.

Mina decided to get to the fun part, unbuttoning and unzipping Eijiro's jeans to free his erect cock. She then slid her panties to the side to reveal her dripping pussy. The pinkette mounted her boyfriend, rubbing her pussy against his dick before impaling herself on it, sending a sudden shock of pain down her spine as it tore through her hymen.

"Y-You okay?" Eijiro asked as he noticed a bit of blood coming out of her womanhood.

"Just...j-just give me a minute, okay?" Mina asked as she caught her breath. The two just sat there, hugging and comforting each other. But it wasn't long before the pain faded away, replaced with pleasure as Mina began to move her hips up and down, her muscular thighs slamming against Eijiro's.

The redhead wasn't content with just sitting and letting Mina do all the work, so he began to thrust up to match her movements. Eijiro also decided to move his hands up her shirt, feeling up her stomach and back muscles until he reached her breasts. Unsurprisingly, the acid girl had omitted wearing a bra tonight, so when Eijiro pushed her shirt up, he saw the pink mammaries and dark pink nipples unobstructed. He used his left hand to squeeze and rub his girlfriend's left breast while he placed his mouth on her right breast, nibbling on the dark pink nipple.

Mina had to bite her lips to keep herself from moaning and waking up her family. But if she didn't have to worry about that, the acid girl would've been screaming loud enough to let the neighbors know she was getting fucked. Mina continued to slam her wide hips against Eijiro, their movements growing faster and more erratic, the two drowning in pleasure as the pink-skinned girl's pussy grew tighter and tighter.

Soon enough, Mina reached her climax, soaking Eijiro's cock and hips with her pussy juice as she orgasmed. Eijiro wasn't that far behind, shooting his seed up into her. After their orgasms faded, the two looked at each and kissed.

"I love you, Mina." Eijiro said with a smile.

"I love you, too, Eiji." Mina replied with a smile of her own. Suffice to say, no more movies were watched that night.

One week later…

"This is sooooo borning!" Mina whined as she placed her head and arms on the table.

"You're the one who wanted to catch up on some homework." Itsuka said. The two girlfriends were currently in Itsuka's room, taking some time to study. As for Eijiro, he had gone with his parents to visit his grandparents. Itsuka still remembered being stunned when their boyfriend showed up with his hair down and black, Mina revealing that Eijiro's hair was naturally like that, and the red spikiness took some hair coloring and gel to get right. Apparently, Eijiro's mother didn't want him freaking out his grandparents with his usual do.

So the girls were left to their own devices for the weekend. But as Itsuka got up to grab another textbook, Mina smirked as she thought about how they could have some fun on their own. And so, the pinkette got up, snuck behind Itsuka, and slapped her on the ass.

"M-Mina!"

"Sorry, but your ass looks way too sexy in those pants." Mina said before taking off her shirt, showing off her dark blue bra, quickly moving her hands behind her muscular back to unclasp it. "What do you say we put the books away and have some fun?"

Itsuka was about to protest...until Mina's bra came off and she saw her girlfriend's perky and pec-supported breasts. For the last week, Itsuka and Mina took turns going on dates and banging Eijiro, so they had become quite familiar with their more perverted sides. But the two girlfriends had never done anything erotic together. So this was new and exciting for Itsuka, enough that she also thought,'Fuck it,' and joined began to strip out of her clothing alongside Mina.

Soon, the two girls were completely naked, taking in the sight of each other's muscular bodies.

"I still can't believe how big your arms are." Mina said, rubbing Itsuka's right arm with her hand. With a smirk, Itsuka flexed her 19-inch biceps for her girlfriend. The pinkette smiled at this and decided to kiss and lick the small mountain of muscle, sending a shiver down Itsuka's spine. The orange-haired girl decided to retaliate by rubbing Mina's thigh muscles.

"You got some big muscles too, Mina." Itsuka said before moving her hand the pink girl's massive thigh and up to her moist womanhood. She then rubbed her fingers against Mina's womanhood, making the pinkette moan. "Wow, you're already wet."

"Shut up and kiss me!" Mina exclaimed before kissing Itsuka on the lips, the orange-haired girl kissing and tonguing her back, taking charge and pushing the pink girl on the bed. The girls continued to make out and feel each other up, their breasts and muscles pushing against each other.

After finishing their make-out session, Itsuka and Mina got into a scissoring position, rubbing their pussies against each other. The girls moaned as they rubbed against each other, their muscular legs entangled as they lost themselves in pleasure. The friction between the two continued to climb, their euphoria overwhelming them. With each movement, their bosoms bounced with them, the erotic visual of their buff bodies adding to the pleasure.

Soon, the girls reached their peak, climaxing and screaming in pleasure. After coming down from their high, Mina smirked as she grabbed her cellphone.

In the meantime, Eijiro was helping his grandfather clean up his attic, until his phone rang with a text message. The naturally black-haired teen looked at the text...and his face turned red.

"You okay, Eijiro?"

"Y-Ya, Gramps! I'm fine!" The red-eyed boy said as he quickly put his phone away. What did he see?

A selfie of a naked Mina laying on top of a naked Itsuka, the two of them smiling into the camera with the text, "Messing around in bed. Love you. Come back soon."

Four days later…

"Alright, that was awesome!" Eijiro said as he, Mina, and Itsuka just finished a workout inside of the Kendo family's home gym.

"I know what you mean." Itsuka said as she stretched her arms. And seeing the sight of Itsuka's back muscles flexing, Eijiro surprised her by kissing her on the cheek, making her giggle.

"Hey, I worked hard too!" Mina whined, grabbing her boyfriend by the face and kissing him. But her nose caught a scent that made her separate from Eijiro. "Woah, we really worked up a sweat."

"Guess we better hit the showers. Who wants to go first?" Eijiro asked. But surprisingly, Itsuka was the one who came up with the next suggestion.

"You know, we can save some water if we shower together." The orange-haired girl said, surprising her lovers.

"My oh my. How naughty, Itsuka." Mina said with a hand over her smiling mouth.

"I think we've corrupted her." Eijiro joked, making Itsuka roll her eyes.

Regardless of any jokes, the buff trio did indeed head into Itsuka's bathroom, stripped naked and hopped into the shower, the warm water cascading over them. Eijiro began to rub soap over Itsuka's body, taking extreme care to rub it all over her back and bosom, making the orange-haired girl let out some moans. In the meantime, Mina rubbed soap all over Eijiro's back, kissing him on the neck as she did so. Looking over his shoulder, the acid girl saw that her boyfriend was fully-erect.

"Better clean ya down here." Mina said, getting on her knees to face the redhead's cock. The acid girl gave the tip a light kiss before she began to lick it. And deciding to be a bit more naughty, Mina lathered her breasts with soap before wrapping them around Eijiro's shaft, rubbing them up and down while sucking on the tip of his dick.

While this was happening, Eijiro and Itsuka started to make-out, wrapping their arms around each other with the water washing over them. And with the sucking and boobjob Mina was giving him made the redhead moan into Itsuka's mouth. The sensations of his girlfriends and the shower made Eijiro cum into Mina's mouth, surprising the girl before she swallowed the white substance. And to her delight, the redhead was still hard.

After drying off, the threesome made their way to Itsuka's bedroom. Eijiro sat on the bed while Itsuka turned around and mounted his cock, impaling herself on the hard member.

"Ah!" Itsuka moaned as she began to move her hips up and down. Eijiro matched her hip movements and kissed her back muscles. Mina decided to join in, placing her lips on Itsuka's right breasts while toying her free breast. The orange-haired girl continued to bounce, feeling her boyfriend's thick cock thrusting up into her, reaching all of the pleasure centers inside her.

"I'm...I'm gonna...AHHH!" With a yell, Itsuka reached her orgasm, her pussy milking Eijiro's dick until he shot his load inside her. The orange-haired girl got off of her boyfriend, letting Eijiro fall onto his back, his dick still hard.

"Alright! My turn!" Mina said as she crawled all over Eijiro before slamming her hips down, moaning as they kissed. But suddenly, the redhead felt a sudden burst of pleasure as Itsuka began to lick any part of his shaft as it came in and out of the pinkett's pussy. The licking only served to arouse Eijiro even more, causing his dick to lengthen a bit more, which Mina felt with a loud yell of pleasure. Itsuka then decided to lick up until she reached the pinkette's vagina lips.

The redhead continued to thrust up into Mina, kissing his lover as they embraced. Soon, Eijiro felt Mina's pussy muscles tighten like a vice, making him coat her insides and causing the acid girl to cum as well.

Next, Itsuka stood on her hands and knees while Eijiro mounted her from behind, grabbing her hips as he began to thrust in and out of her. Mina wrapped her muscular arms around her boyfriend's chest, rubbing his abs as she kissed his neck, which only encouraged Eijiro to thrust even harder into Itsuka.

As they fucked, the orange-haired girl's eyes rolled up, her mouth hanging open. Her arm, leg, and back muscles flexed as she held herself up, bracing against her boyfriend's movements. And in this position, Eijiro's cock was piercing her womanhood deeper and deeper. After a few more minutes of thrusting, the two muscular teens ended up cuming at the same.

After that, Mina sat on her back before Eijiro placed his hands on her thighs before thrusting into her. The acid girl began to moan until Itsuka sat on her face. The pinkette began to lick her girlfriend's pussy, finding the mixture of Itsuka's love juices and Eijiro's sperm strangely intoxicating. And with Mina licking her womanhood, Itsuka grabbed her breasts, her eyes brimming with lust as she looked at Eijiro. The two lovers then kissed, losing themselves in pleasure while their girlfriend moaned underneath them. And soon, the redhead ended up coating Mina's insides, with the acid girl achieving her orgasm soon afterwards.

In the final round for the night, Eijiro sat on his back, holding himself up a bit on his elbows while Itsuka and Mina rubbing their soaked pusssies against his erect member. A coat of sweat made their muscular bodies shine against the room light as the threesome moaned like crazy. The sensation of feeling Itsuka and Mina's body weight while their pussies coated his dick felt amazing to Eijiro. The girls were also in nirvana as they felt their boyfriend's hard member rubbing all over their vaginal lips.

Eventually, the pleasure became too much for them, with Mina and Itsuka soaking Eijiro's member with their love juices while the redhead shot his load all over his girlfriend's lower bodies. The three feel on their backs, breathing heavily as they reeled from their orgasmic bliss.

"I...I think we need to take another shower." Eijiro said.

"Agreed." Itsuka breathed out.

"That was awesome." Mina said with a dumb smile on her face.

After that, the weeks passed by, and the muscular threesome soon began their 2nd year at UA. With it would come new challenges in their goals to become professional heroes. Along with some unexpected surprises.

Author's Note: Now we get to the sweet, sweet, muscle sex! And I'm happy to say that the poll to determine the harem is officially over. Ho boy, this one big harem with 12 beefy beauties getting on with Eijiro. So here's all the girls who will do the horizontal mambo with the Red Riot, Alien Queen, and Battle Fist (alongside how many votes they got):

Rumi Usagiyama (10), Setsuna Tokage (9), Momo Yaoyorozu (8), Reiko Yanagi (8), Pony Tsunotori (7), Tsuyu Asui (6), Kyouka Jirou (6), Nejire Hado (6), Yu Takeyama (6), Saiko Intelli (6)

But this doesn't mean that we're done with polling for this story, I've got another thing for you, the lovely degenerates reading this, to decide; the sizes of these ten girls. With twelve girls, we're gonna have four girls in each different class of muscular builds: Superheavy, Heavy and Light. Yes, this is similar to the vote for my ill-fated Naruto story. And yes, this is inspired by the three weight classes from Pokkuti's Pinnacle of Physique comic.

(Speaking of Pokkuti, he's recently started a My Hero Academia FMG comic called My Muscle Academia. Be sure to be on the look out for that on Deviantart.)

Here's a description for each of the different muscular builds (somewhat lifted from POP).

Superheavy: 28 to 32 inch biceps and massive thighs. Shoulders as large as a character's head. Arms as large as a torso. Exploding pecs and lats. Proportions resemble an inverted triangle.

Heavy: 22 to 27 inch biceps and big thighs. Very pronounced shoulders and lats.

Light: 17 to 21 inch biceps and muscular thighs. More on the athletic and fit side.

Naturally, details like definition, breasts, ass, and hip side will depend on the heroine in question. And as indicated by the first chapter, Mina and Itsuka are already superheavy (so is Eijiro). So the first size-choosing poll will determine which two heroines will gain a superheavy physique alongside those two. Like with the first poll, the first two girls to gain 5 or more votes will become absolute amazons alongside Mina and Itsuka.

Cast your votes and have a safe & happy Easter!
