She's more than okay with it!

"Hello?" Setsuna answered in a slightly groggy tone.

Izuku was about to answer her, when he suddenly moaned, and looked down to see that Ochaco had taken his manhood into her mouth, and started bobbing her head. "Ah, unh, sorry," he panted.

"Let me guess, Momo or Ochaco just started sucking you off?" Setsuna asked with barely concealed amusement in her tone.

"Ochaco," Izuku confirmed. "Oh... sorry about that."

"Oh, don't apologize, it's hot," Setsuna giggled. "So what's this call about?"

Izuku took a second to bask in the feel of the stimulation of his cock, and then told Setsuna, "So... Tooru just asked to join our date. Do you have any issues with that?"

As Ochaco pulled off to lick his shaft with her specialized tongue, Setsuna paused. "You really get around, don't you?" she teased.

"You saying that like it's a bad thing?" Momo quipped as the purring Ochaco stroked him with a hand, and licked his testicles. Though she kept her purring at a low enough volume to keep Setsuna from hearing over the phone.

"Not at all, I'm more impressed. I think he's got more than enough boyfriend material to go around, and it really helps that I'm bi," Setsuna giggled. "And it's really hot just how easily you can pick up other girls! Sure, she can join us! In fact, she can even pick our destination, I think!"

"You sure about that?" Izuku panted as Ochaco once again took his pleasure stick into her eager orfice.

"Hey, you let me pick the location of the first date I had with you guys, only fair to extend the same courtesy to her!" Setsuna noted.

"...fair enough," he grunted as he bucked his hips. Ochaco was getting really good at giving oral, and not just because of her enhanced tongue in Neko form. "Same time?" he then asked through his panting.

"Yeah, same place too! See you then!" she replied, hanging up.

"...she really is into this, and we haven't even brought her into the harem and in on our secret~!" Momo giggled.

"Yeah, Nyah... she's practically begging to be yours in some capacity," Ochaco giggled as she pulled off Izuku again, stroking him with a hand.

"I'm aware," he chuckled as Ochaco resumed her blowjob, and didn't stop until he let his cock erupt in her mouth.

"Mmm, yummy as always, Master, Nyah," Ochaco giggled as she swallowed it all down.

(So, I'm thinking about starting a whole different branch where it's Denki who finds the lamp instead of Izuku, if you guys all want a route with a slightly less restrained protagonist. For those of you who think Mineta is a better choice, I really just don't like him, and honestly... he's just not attractive at all to me, I'd be turned off really fast making him the protagonist. Denki is a much more enjoyable option for me. But do let me know if that interests you guys.)
