Itsuka and Ibara arrive and Setsuna falls

The door opened, and the last members of class 1-B entered the room. First Itsuka who nowadays was much an enigma, often having a twin personality of a vacant absent minded bimbo with a mind focused on naught but shopping and sex and that of a genius who could effortlessly manipulate everyone around them or invent anything.

Ibara wasn’t much different from how she had once been, devout and spiritual. But now it was one that was dripping in sexuality and devotion to her green haired god. She looked at her classmate as if Setsuna was some poor victim of her own misguided belief. Like she was wayward sheep and Ibara her Shepard.

"You summoned us Albedo?" Ibara asked, with a dutiful bow. Itsuka however just started giggling like mad.

"I think it's like Setsuna's turn to join our little harem. And it's totally about time, are we going to like fuck her into submission." Itsuka giggled as Albedo smiled knowingly.

"You know it, I want all of you in 1-B to bring your last teammate to her knees. Setsuna I believe you have very sensitive skin." Albedo said, and like that Setsuna felt her skin light up as if on fire. She could feel every speck of dust, every small gust of wind, even the light seemed to tickle her skin.

"Girls, bring your last classmate to her knees." Albedo ordered and the others chanted in agreement.

"Yes Mistress Albedo." They chanted, with Melona pulling back as her classmates dogpiled her. First there was Yui who grabbed her breasts, sending jolts of pleasure throughout her blood, Setsuna couldn't help but letting a erotic scream through the sky.

"Oh I think Setsunnie enjoyed that." Itsuka giggled, "hey Yui why don't ya use your quirk to make give her some great big boobies to play with."

"Yes Mistress Itsuka." Yui obeyed, squeezing Setsuna's breasts firmly and causing them to balloon outward to obscene levels. Soon she couldn't see her stomach for her breasts, she moved her hands to her new assets to feel them. They were soft and squishy and were so sensitive that they were like tesla coils, sending shocks of pleasure throughout her body.

"Wow that seems like it was like super effective, Yui why don't you take a taste?" Itsuka asked with her sexy, breathy voice.

"Yes master Itsuka." Yui replied heaving one of her new mighty breasts in her mouth and began to suck. Eyes falling shut as bliss overtook her body.

"Oh but that's like only breast covered, we don't want the other to get lonely right Kinoko?" Itsuka said eyes darting to her mushroom loving classmate.

"Understood Mistress Itsuka." Kinoko replied, crawling to Setsuna's other breast and and placing her tongue along it. Setsuna felt a chill of shock creep across her skin before being subsumed with growing lust.

"Reiko, Pony, between the two of you take her sinful pussy and ass. Save this wayward soul with sex and bring her under our God's control." Ibara ordered, and the other two nodded.

"Yes Mistress Ibara." They replied, as they crawled up the foot of the bed, Pony taking Setsuna's pussy while Reiko levitated her waist into the air and took her ass between her lips.

"Please fight this." Setsuna goraned.

"I will never resist my lord." Ibara explained, her thorn like hair tearing her and Itsuka’s clothes apart. The two then leapt onto the bed, sandwiching Setsuna in between their bodies and breasts. Setsuna couldn’t help but feel the blush form on her cheeks. Not just from how they smothered her, but from how hot they were. How big their breasts were. She was like a teenager finding porn for the first time.

“Let me go.” She whimpered, trying to remain stubborn but all the while feeling her resolve crumble.

“Why are you like not enjoying this?” Itsuka asked mockingly, “Pony is she enjoying this?”

“Yes Mistress Itsuka.”

“Oh I like that- Mistress Itsuka. If you’d joined us earlier then perhaps you too could be a mistress.”

“Fuck off.”

“No we’ll fuck you, then you’ll fuck us as our slaves. Then we’ll loan you to Master Izuku and you’ll fuck him.

“No.”

“And then you’ll be happy, and horny. You want that don’t you Setsuna?”

“No.” She lied, she did she really did.

“Really? You enjoy having all that pleasure well up inside you.”

“No.”

“Then say it.”

Her tits, her pussy, her ass, her skin, all of it was unbearable.

“I-I.”

“Yes?”

“Do it Setsuna.”

“Become one of us.”

"I-I ple-pledge myself to- to IZUKKKUUUU!" She screamed the last part, as her eyes rolled into her head. Cum flowed out of her pussy, her face glowed a feverish red and the greatest feeling of lust and pleasure that she had ever felt in her life consumed her.

"Thank you Mistresses, thank you for letting me see the light." She cried, her eyes awakening to her new life. Now seeing her classmates-no her mistresses differently. As if for the first time she saw how beautiful they were, how perfect, how she needed to serve.

"No problem ****, I am always happy to lead a wayward sheep back to her position in life."

"Excellent work girls." Albedo admitted.

"You even had me half way to cumming there." Melona said, shifting back into her normal form.

"But you stole Reiko when I was fucking her." Nejire pouted, "I was really close too."

"Maybe I could help." Shion offered, stripping out of her jacket.

"Yes please, Melona you wanna make it a threesome?" Nejire asked, but Albedo interrupted.

"Perhaps we should bring our new selection to their Master and Mistresses first?"

A/N: Unless someone volunteers to continue the story then the next chapter will likely be the start of hiatus. Though I might make a non canon epilogue at some point.

If someone wants to volunteer and wants my help to beta and suggest things then send me a pm. If they want to branch off at an earlier point of the story and still want my help then that'll be fine too.
