They do, and it's explosive!

The group continued to stimulate Setsuna's separated body, when Tsuyu felt her wrists twitching. "She's waking, ribbit," she noted.

Tooru also woke, and she and Setsuna blinked. "Wha... Uuuwaaaaaah!" they both yelped out as they spasmed from the stimulation hitting them both all at once, Setsuna of course thrashing a bit more due to additional stimulation. Izuku and Momo set down the breasts, exchanging grins.

"Eeerk..." Tooru moaned, coming down first, and blinking at everyone. "What the heck was that?"

Setsuna slowly settled down, murmuring a bit incoherently as her eyes were rolled up. "...damn," she wheezed.

"Yeah, we kind of stimulated your bodies while you were asleep," Izuku chuckled.

Setsuna started giggling, before looking at Itsuka blearily. "Hey, stop!" she stated, given that Itsuka had started tickling her feet again.

Itsuka smirked and released them, before pouting slightly. "Darn. Didn't get the chance to use that marker," she noted.

Setsuna pulled herself together, literally and figuratively, before sitting up beside Tooru, and stuck out her tongue at Itsuka. "You were gonna draw on my face? Real mature..." She then looked towards Izuku. "It all went well, by the way! Tensai turned out to be a lot of fun to play around with!"

Izuku, having been about to ask about it, smiled and nodded. "Good. Hopefully, Iida will be alright once his brother recovers."

Itsuka straighted up, and began to undress. "So then, Izuku... Or should I call you Master now?" she began, smirking as she dropped her uniform top. "How do you want to do this initiation thing?"

"Well, getting naked is certainly a good start," Izuku noted as he watched her strip, the other girls settling in to watch as well.
