Yes, he and Mina share!

"Okay, Mina, you want to share Jun with me?" Izuku asked Mina, who nodded enthusiastically.

"I would most certainly like that!" she chimed eagerly. Already, she had started to work on removing her clothes, revealing more of her pink skin.

Izuku nodded, continuing to play with Jun's boobs. Jun crooned at his touch as he turned to Momo and Ochaco. "You two... go ahead and take charge of Kirishima," he then ordered them, and they nodded, taking the redhead to a corner. While Ochaco was a natural sub, she could dominate someone if ordered to by her Master, as that was still technically a submissive act.

Once Mina was nude, Izuku looked at her, and ordered, "Sit on the floor, and spread your legs."

"Mmm, yes Master," Mina agreed, already locked into her **** mentality, though also still ready to command Jun. Izuku proceeded to pull off Jun's harem pants as Mina complied, sitting in a position to rest back on her hands as she parted her legs, watching Izuku slide Jun's harem pants down for access to her pussy. "****, come lick my pussy," she then ordered Jun, showcasing her switch mindset.

Jun glanced at Izuku, who nodded. "Yes Mistress~!" she chimed, dropping onto her hands and knees, crawling over to Mina and lowering her face towards Mina's glistening folds. She eagerly extended her tongue, and began licking, moaning in pleasure at her own obedience as Mina crooned. Izuku proceeded to kneel behind Jun, pulling his cock out.

"Good girl," he praised her, even as he slid his dick into her glistening folds.

"Mmmph!" Jun moaned, and continued to lick Mina, unwilling to be distracted from obeying orders, after all, obedience was pleasure to her. Especially when physical pleasure was added. Ultimately, this was the personality of Yumi's that wanted only to obey orders and got pleasure from doing so. Sure, all of them had the trait to a degree, it was just strongest in her.

"Good girl indeed," Mina crooned as she put her hand on Jun's head, turning her gaze towards where Kirishima was naked and lying on his back, being mounted by Ochaco, and Momo straddling his face.

"That's it, use your tongue, right there," Momo was coaxing the redhead, instructing him on how to properly give a girl oral. Kirishima did his best to follow her every instruction as Ochaco rode him.

Izuku squeezed Jun's ass as he began to pump his hips harder into her, making her moan in pleasure and bite her lip for a moment, before she started licking Mina's clitoris, replacing her tongue in Mina's folds with a few fingers.

"Oh yeah, keep going!" Mina gasped, writhing her hips with every lick. By this point, Izuku was pounding into Jun, groaning as her vaginal walls were squeezing his cock with great intensity. It was amazing what super strength could do for all muscles in the body, not just what was useful in combat.

Kirishima meanwhile had already cum twice inside Ochaco, but hadn't gone down thanks to the enchantment, and was enthusiastically licking Momo's cunt, holding her thighs. His enthusiasm and energetic approach made up for his lack of experience, and allowed Momo a good amount of pleasure. Still, both she and Ochaco decided to help each other out, reaching for each other's breasts to grope each other and add to the stimulation.

Mina began to caress her boobs with her free hand, biting her lip and tightly shutting her eyes. "C-cumming!" she squealed, throwing her head back as she felt herself reach her peak, her body stiffening before relaxing. "Oh God..." she wheezed as she laid back, panting hard, each inhalation pushing out her chest in a way that drew Izuku's gaze.

He and Jun weren't far behind, Jun screaming in delight as she reached her climax while Izuku grunted, his seed spilling into her. They both crumpled to the floor, Izuku laying atop Jun, kissing her neck passionately as she moaned and relaxed under him.

They rested like that for several minutes, at least until Kirishima had managed to get both Ochaco and Momo off. "...how many times did he cum inside you?" Izuku asked Ochaco.

"Three," Ochaco giggled. "Less than before with Momo, though we did help him out by stimulating each other's breasts." Momo nodded in agreement.

"...screw you both, I'm counting that as an improvement," Kirishima panted, making the genie and her **** sister giggle at him.

(This should have come out last night, but unfortunately, the site's updates had other plans. I ended up losing half the chapter when I tried to post it, unfortunately. That was infuriating, but oh well. It got done at least, better late than never.)
