'Koreijou Ika Senai de...tsu' ~ Gendo o Shiranai Gitei no Chikan

"Itsuki's fingers are pushing inside me... Oh god..." Packed into a crowded train, Saya finds herself being stirred into a state of helpless arousal, her body growing slick despite the risk of being discovered. Even so, she cannot stop her hips from moving on their own. Saya is an office worker at a university, troubled by the cold distance she feels from her husband. The one who offers her comfort is her brother-in-law, Itsuki—but behind his warm, affable demeanor lies a hidden fixation on her body. On the train, he boldly presses his hands against her, guiding her with feigned concern. "Come on, Saya... Steady yourself." As he toys with her sensitized skin, he slips her underwear aside and begins to relentlessly pursue her most private places.
