You ask when you can help them.

"Not now, obviously, you see, we need to prepare ourselves for it. The next few days will be reserved for it. Midnight is okay with letting us do the breeding instead of class, as long as we write about it all afterward." Toru says. "It is planned for all six of us. Toru is first tomorrow, then Momo, Ochaco, Me, Jiro, and lastly Mina." Tsuyu adds. "Okay, that sounds good. I assume you planned it last night?" you say, "Yep!" Jiro says. You all talk about the next few days for a while. Eventually, Toru says, "Could you show us your... penis?" She asks. "Yeah, would that be okay?" Jiro asks. "Sure, but it would not be even if only I do something. I will do it if you all show me your tits.". The girls look at each other nervously. Eventually, Tsu takes her shirt off, revealing her large breasts. After a second, Jiro does the same. "You can't see mine..." Toru says. "Okay, how about you let me feel them to make up for it?". After a moment, "Okay. Be gentle, though. No one has really touched them before.". You walk up and open her jacket. She is not wearing anything under it, so you reach for where her tits should be and feel them. They are as large as you expected and very soft. You slowly touch around them and lightly rub her nipples. You get an idea of what they are like and stop. "Okay, now it's my turn.".You pull down your pants, letting your dick free. "Whoa, why is it so big!?" Jiro exclaims, "That is bigger than the example Midnight gave us.". they all closely examine it for a few minutes before you all put your clothes back on.

"Okay, tomorrow we need you to be in Toru's Room at noon. Some of us might listen to make sure everything goes well, but we won't go in unless we hear something that isn't right.". You nod, and everyone moves on with the rest of their day. Your sister returns and talks about everything. She tells you about their plan, and you tell her the other girls asked about it already. "This is really happening, huh?" She asks, "It is. It's like a dream." You say, "If this is a dream, I hope it doesn't end." 'I agree." You both continue to talk for a while about the girls and the breeding of them. "So... Would you breed me?", Your sister asks.
