Yui was being bullied with chants of "Stinky! Stinky!" and was left alone in the classroom, crying. Her homeroom teacher, Yuna, noticed and came in to comfort her—but in truth, Yuna had a smell fetish. She became aroused by Yui's scent, repeatedly shouting "stinky!" while obsessively sniffing every part of her body and licking her all over. Gradually, Yui herself began awakening to her own smell fetish, unable to resist deeply inhaling Yuna's pungent odor, eventually intertwining tongues with her in passionate, intense French kisses. This is a lesbian work specifically focused on smell fetish, filled with thrilling excitement as the characters constantly exclaim "stinky!" throughout.
