Lesson Learned

But I can't ignore it either

"Yeah, like when I was a kid." Rio yawned, stretching. "Look, it's not really any of your business," she said, curling an arm around Mitsuko again. "I mean, I'm going through puberty so I'm still sorting it out but honestly I prefer kissing girls and I'm more attracted to them." She shrugged. "I mean, men are interesting and I can appreciate their bodies and stuff—"

"Like Mr K!" Kurahashi chimed in.

Rio smirked. "Yeah, like that." She shrugged. "But like, I'm not physically attracted to them, at least not the parts that matter," she told them as they listened intently. "It's like when you first realise you're attracted to someone, it's a process," she tried to explain. "I'm discovering stuff the more I'm with Mitsuko."

This made the girl in question blush. "Which is different with me because I'm physically attracted to both."Mitusko's blushed darkened. "All parts..."

"Oh..." Seo frowned, seeming to think about it.

"I get it!" Kurahashi beamed. "I know for sure I'm straight because of Mr Karasuma." Her eyes filled with hearts. "He's amazing!"

Gakushuu's eyes widened. "Isn't he your teacher?"

"Yep!" Her smile grew while the other four of the Big Five gawked. "He sort of has this thing going on with Bitch-sensei so I'm keeping my distance...but if it doesn't work out then he's free game again!"

"Uh..." Araki looked concerned. "Who's Bitch-sensei?!"

Koyama looked confused. "Yeah, what the hell are you talking about?"

"You do realise underage student-teacher relations are illegal?" Gakushuu remarked dryly.

"I'm willing to wait!" Kurahashi said brightly. "It's not illegal if I'm eighteen!"

Mitsuko burst out laughing along with the others in Class E, confusing her brother and his friends.

Araki frowned, and then shook his head. "You guys are so weird."

"Yeah, we know." Mitsuko smiled and snuggled closer to Rio, resting her head on her chest as they leant against the wall. "Can we open presents now?"

"We still have twenty minutes before it's 4pm," Gakushuu complained, tapping the watch she'd got him.

They all stared at him blankly.

He scowled. "...Fine."

"Yay!" Kurahashi jumped to her feet and went to grab the presents.

Mitsuko stayed where she was, thinking about what Rio had said. "...Are you really discovering stuff with me?"

Rio smirked. "Well, yeah, you're my girlfriend." She pinched her cheek, garnering a glare. "That's kind of what happens when you're in a relationship."

"Well, yeah..." Mitsuko looked embarrassed. "It's just the way you said it...it's nice...like we're special." She smiled faintly and cupped her face, kissing her. "Like this is important."

"Course it is." Rio grinned, making her squeak when she kissed her neck and nibbled the skin. "This is our first rela—"

A familiar siren noise caused the two to break away while everyone else nearly jumped out of their skins.

"GAKUSHUU!" Mitsuko yelled at her brother.

Her brother paused the siren noise on his phone, looking unimpressed. "No underage inappropriate behaviour in the household, remember?"

"I'm sixteen!"

"Rules still apply," he replied, his finger hovering above the play button. "Or I'll tell mom."
