The Beautiful Sumo Grand Champion - The Night I Was Defeated by His Secret Technique

Nozomi, a clerk, is head over heels for top salesman Kotaro... except she's never actually spoken to him. She spends her days fantasizing about things that won't ever happen, until one evening, Kotaro asks her to accompany him! Is he after her body...? With uncertainty and hopefulness warring inside her, Nozomi can't pass up this opportunity. She goes with Kotaro, only to find him standing before her practically naked! It turns out he's a sumo wrestler, and before she knows what's happening, Nozomi winds up having a practice bout with him! When she feels Kotaro's strong muscles and smooth skin pressed against her, though, she can't help slipping back into fantasy!
