Someone accidentally seeing girls kiss is a trope that'll never get old.
Seriously, she's full out going for it and you're stopping her? After you asked her? That's when you're supposed to let it be!!!
I guess the lonely girl can defy the thirsty girl... Give her some love, Honda-san, she wants it bad. All over her body. Like time to take her to your room or a hotel or whatever.
Or just have sex in the classroom like a few stories I can think of...
Patience is a virtue I don't naturally have but I think we must learn to have. I'd love to see an obligatory fuck chapter that's a culmination of their trials etc.
