Mion wakes in the morning to find her adult coworker and senior, Yume, sleeping beside her. When Mion closes her eyes again, Yume wakes and leans in for a kiss. Mion pretends to be asleep, but Yume’s overpowering morning breath forces her eyes open. As Yume makes her smell the foul breath while licking and sucking her nose, both women gradually slip into a trance.
