As it truly did feel like he was having sex in a full-body hot tub, Izuku quite enjoyed making slow and gentle love to Mina, her translucent pink, lube-like acid swirling around them and ensuring he could move freely, a stark contrast to having sex in actual water.
Though she expected things to be a lot more intense, Mina would be lying if she said she didn't enjoy making out with Izuku while his dick slowly but surely conformed her insides to match its dimensions. Her brows creased when he abruptly started fingering her butthole, but she didn't ask him to stop since her acid functioned as an exceptional lubricant.
Separating from Mina's lips, Izuku revealed, "I'm about to cum..." while lifting her ass a bit. Mina narrowed her eyes mischievously and licked her lips seductively in response. However, instead of playing around and teasing him, she promptly raised her butt, allowing his cock to slip out of her before an 'accident' could occur. Izuku didn't mind cumming inside Rumi since the thought of impregnating her got him pretty fired up, but he knew Mina and the rest weren't ready to be mothers...
While directing most of her 'acid' to a large basin, prepared in advance, Mina pointed out, "I 'am' on the pill, you know? Are you sure you don't want to cum inside me? I heard you came inside of Momo like ten times when you took her virginity."
Adopting a wry smile, Izuku pointed out, "That was an experiment to see if we could boost her Luck. Besides, even if I somehow got her pregnant, I'm pretty sure her parents would step in to help raise it..."
Nodding in affirmation, Momo explained, "It wouldn't be my parents, per se, but we have people that specialize in child-rearing. I'm also confident I could maintain my grades, even if I have to take a short maternity leave, so getting pregnant isn't a serious concern for me."
"It must be nice being rich..." muttered Ochaco, drawing quite a few gazes her way.
Starling slightly, Ochaco raised her hands, waving them from side to side as she embarrassedly exclaimed, "Sorry, that just kind of slipped out! I'm not envious or anything...!"
Catching Ochaco more than a little off guard, causing her brain to short circuit, Izuku replied, "That's good. Because the moment we all became serious about making this work, you became the girlfriend and sister of a pair of billionaires. I've already set aside pension funds for both of your parents, so you shouldn't worry about finances from now on and focus on what makes you happy. I know I am..."
Regaining her senses by the time Izuku was finished speaking, Ochaco exclaimed, "Y-You didn't have to do something like that, Izuku! I-"
Holding up his hand to silence whatever Ochaco wanted to say, Izuku stated, "You girls compromised more than anyone could rightly ask for when you decided to share me amongst yourselves. You've even made concessions to allow me to sleep with other women, so how could I not do everything I can to ensure your happiness? I'm determined to spend the rest of my life returning the favor you've shown me, and I won't regret it, not even for a moment."
Feeling a little choked up, Ochaco became teary-eyed as she muttered, "Izuku..." in an emotional tone tinged with sentimentality.
Reaching out to wipe away the tears from one of Ochaco's eyes, Izuku's expression softened as he said, "Now isn't the time for tears...we're here to have fun and indulge ourselves. But don't worry. I'm more than willing to lend you my shoulder once we're done..."
Exhaling a soft laugh, Ochaco wiped away her tears before putting on a bright smile and joking, "I'm suddenly feeling a lot hornier..."
"First things first," said Mina, interjecting herself into the heartwarming exchange before pointing at Izuku's dick and asking, "What are you going to do with that thing that's on the verge of bursting? I don't mind finishing you off with my mouth, but I'm a little apprehensive about lapping up my own love juices."
"I could take care of it," proposed Tsuyu, touching her cheek and staring at Izuku's cock as if it were a particularly tasty treat. In fact, she enjoyed sucking his dick quite a bit since she 'knew' she was the best at it, at least among the girls present...
Presenting Izuku with a tempting alternative, Momo raised her hand and offered, "I could also lend you my bottom. I completed all the necessary preparations this morning."
Prompted by Momo's words, Toru raised her hand excitedly, exclaiming, "Oh! I've been wanting to try anal as well~!"
Though he certainly wouldn't mind fucking Toru in the ass, Izuku quickly replied, "That wouldn't be a good idea. Momo has taken all the essential steps to prepare her ass. If I were to do you without any preparation, you could get an anal lesion or a severe case of hemorrhoids..."
Covering her ass with both hands, Toru's excitement mellowed into an awkward smile as she said, "Allow me to retract my statement...hahaha..."
Nodding his head, Izuku turned his attention to Momo, adding, "I'll have to do you in the butt later. Even if it's cleaner than a whistle, I don't think the others here would appreciate me going from your ass to their pussies without a proper cleaning..."
With Izuku pointing it out, any interest the girls had in watching him fuck Momo in the ass waned. They certainly wanted to see it, but since they still had a lot of oral and intravaginal play to do, anal would have to wait. Thus, by process of elimination, the duty of siphoning Izuku's semen and preparing his dick for the next girl fell to their local Tongue Goddess...
"Ribbit, ribbit..."
...
..
.
Undoubtedly as a result of the surprise he had given her earlier in the afternoon, Ochaco was 'very' enthusiastic when it came time for her to ride Izuku's cock. Momo and Toru certainly weren't lacking in vigor, but Ochaco was like a woman possessed, nearly succeeding in wringing out Izuku's semen before he could pull out.
Fortunately, Izuku had anticipated Ochaco's almost compulsive need to 'repay' him, pulling out at the last moment and shooting his seed straight into the air without breaking free from her aggressive kisses. Curiously enough, even though he didn't see it, Tsuyu shot out her tongue, catching most of it before it could fall, earning her some 'curious' looks from Momo, Toru, Mina, and Kyouka.
Realizing that she and Izuku were no longer connected, nearly a full ten seconds later, Ochaco separated from his lips, asking, "What happened? Did you...did I make a mistake...?" between panting breaths.
Giving Ochaco's ass a light smack, Izuku replied, "You were incredible. I just don't think you're ready to be a mother yet, so I pulled out before you could milk me with your enthusiasm."
"O-Oh..." replied Ochaco, her already flushed face becoming redder at the notion she might have seemed desperate. She had even forgotten to test her Ultimate Move, her brain effectively going on autopilot as she focused on kissing and moving her hips...
"How cute..." said Izuku, surprising Ochaco by positioning the tip of his dick back at her entrance. A look of confusion marred her face, but she didn't hesitate to swallow his cock to the base before asking, "Is it still my turn...?"
Nodding his head, Izuku replied, "Yeah, but we're going to change things up a bit to keep them fair. Mind sitting up?"
Complying without delay, Ochaco was going to ask what Izuku wanted her to do but didn't need to when he looked to Tsuyu, remarking, "I doubt you need the extra preparation, but want to sit on my face? I'll return the favor a bit..."
Perking up, Tsuyu asked, "Are you sure? My juices are a little more...robust than normal. I don't want you gagging or throwing up, ribbit."
"I'll be fine," assured Izuku, waiting for Tsuyu to position her ass over his face before tearing apart her wetsuit-like tights. He received a faceful of her distinctly vicious, pheromone-filled love juices when the fabric gave, but that wasn't enough to deter him. Tsuyu had sucked his dick 'a lot,' so he felt obligated to at least try and return the favor by spreading apart her pussy lips and working them over with his mouth and tongue.
"Oh? This is quite pleasant..." remarked Tsuyu, narrowing her eyes slightly as she lowered her hips and allowed Izuku easier access to her interior. It didn't feel as good as when she did it herself, but she could tell that Izuku didn't lack experience. She and the other girls had practiced fingering and eating each other out during their training, so Tsuyu knew what it felt like when someone had no idea what they were doing...
Realizing that she should probably do something, Ochaco placed her hands on Izuku's lower abdomen and began rolling her hips from front to back. This set of circumstances was actually something they had trained for, but as Tsuyu was the one seated across from her, Ochaco was a little apprehensive. The former was the girl she was the closest to among all the girls in Izuku's harem, but Tsuyu's tongue could be pretty intimidating when you knew what it could do...
Seeing through Ochaco's thoughts, Tsuyu didn't attempt to kiss her as they had been instructed to do in such situations. Instead, she placed her hands over Ochaco's as a sign of support before narrowing her eyes and enjoying Izuku's attempts to make her orgasm with his mouth. He failed, but Tsuyu didn't hold it against him as it was difficult to compete with her self-gratification when his tongue was only a few centimeters compared to the twenty meters hers could reach...
...
..
.
After another close call with Ochaco, Izuku gave Tsuyu a fairly 'thorough' dicking to compensate for his inability to gratify her with his mouth. She insisted it was unnecessary but enjoyed it quite a bit when he put her feet over his shoulders, placed a thick pillow under her butt, and made love to her while massaging and kissing her thighs and calves.
Since Tsuyu was one of the more difficult girls to make orgasm, Izuku spent nearly forty minutes fucking her while Momo, Toru, and Mina used the nearby kitchenette to prepare lunch. It was a little surreal to have sex while people were cooking and chatting nearby, but Izuku kind of liked it. His 'ideal' relationship was one where everyone behaved casually instead of treating every moment together as if it needed to be meaningful. Thus, he wouldn't have minded it if Mina and Toru had put on a movie or started playing video games on the nearby couch. It was much better than having everyone crowding around him, waiting for him to finish...
Fortunately, after acquiring her Thermoregulation Perk, Tsuyu no longer passed out during sex. It was a little awkward when she suggested ways he might be able to make her climax faster, but Izuku ultimately took it as constructive criticism. Tsuyu's physiology was different from most girls, so he was still learning how to handle her 'efficiently.' Once he did, Izuku was confident he could get her to moan just as loudly as Momo. For now, much like Kyouka, he just needed to be patient...
...

"Are you sure about this...?" asked Izuku, referencing the purple, bob-haired girl determinedly trying to locate the entrance to her vagina with the tip of his dick.
Furrowing her brows slightly, Kyouka pointed out, "Everyone else gave you a ride, even Tsuyu. I don't want to be the only one on the receiving end when we're supposed to be the ones giving you a present..."
Nodding his head, Izuku's voice softened as he advised, "Just be sure to take it nice and slow. This can be a pretty dangerous position for virgins..."
"Whatever..." muttered Kyouka, breaking eye contact with Izuku just as the tip of his dick entered her pussy. Then, as if to spite him, she lowered her hips with little hesitation, immediately becoming statuesque...
"..."
"..."
"..."
"..."
"..."
"..."
"..."
Contrasting everyone's expectations, Kyouka didn't immediately cry out after breaking free from her statuesque state. Instead, she slowly closed her legs, slumping her head and shoulders until her bangs covered her eyes before muttering, "Just...give me a moment..." with barely restrained pain in her voice...

(A/N: Oof...also, this might be the last lemon chapter for a while. I intend to dedicate an entire chapter to Izuku's relationship with Kyouka in the future, but I've been wanting to transition into the I-Island arc and the 'actual' plot for quite some time. Also, also, let me know what you think about the novel in the comments section! If that's too much trouble, but you still want to show me you're enjoying it, feel free to bash me over the head with your power stones. The pain and concussions make me stronger.)
