He proves he is indeed interested in her small chest.

He thought about it for a moment, before he walked up to Momo and whispered in her ear, "Would she hold it against me after the spell breaks if I made her flash me?"

Momo focused her gaze on the waiting Jiro for a moment, before smiling and shaking her head. "You should be good on that front, Master."

Izuku nodded, and turned back to Jiro. "Jiro, show me your boobs," he ordered her.

Jiro immediately experienced a rush of delight at the order, and didn't even hesitate. "Yes sir!" she agreed, unbuttoning her uniform top, and pulling it open. Once that was done, she gripped the hem of her undershirt, and pulled it up over her midriff, and as the hem and her hands reached her breasts, she shifted her fingers to snag her bra, pulling it up as well.

There was a slight bounce as her small breasts fell back into place once they were exposed. There wasn't much to them, barely enough for handfuls, but that did nothing to detract from how attractive they were. Their shape was perfect, and her nipples were quite perky. Jiro was grinning eagerly as she displayed her chest, completely enthralled by the experience.

Then the spell broke, and she paused. Her enjoyment of the situation didn't fully fade, but it was buried under a wave of embarrassment. "Ack!" she yelped, turning around, and quickly pulling her clothes back into place. As she did, she replayed the experience in her mind, how good it felt to let go and submit without any inhibitions in the way. She took a deep breath, and said, "...okay, yeah, I get it... I can definitely see the appeal now..."

"Told ya!" Ochaco teased.

"So, I take it you're open to receiving the invite in two weeks?" Momo asked.

Jiro didn't even need a moment to think about it. Though she still had her pride and inhibitions, they weren't enough to deter her temptation to potentially join this group. Maybe make her feel embarrassed about being so open to it, but that was it. "...I guess I am," she admitted with a soft smile. "I will certainly be looking to see if we got chemistry myself."
