[Syounen Heroine (Tamaki Yui)] Why don’t we start with nipple kissing? [Pangean]

A curious schoolgirl seizes her chance when her mom is out for the day, inviting Yuuki over and admitting she wants to try the grown-up things their classmates only whisper about. Undressing together turns into flustered giggling over her flat chest and kid-sized training bra, then into something far more heated—her shimapan-clad hips grinding against him as an itching ache builds that she can't explain or resist. When she finally asks if they're going to kiss, their first clumsy kiss lands somewhere neither of them planned, and the breathless afternoon of innocent exploration is only just beginning.
