Yuki Hiiragi, the single mother living in the apartment next door, crossed the line with me by chance. After that, our uncontrollable passion grew stronger each day, evolving into an intensely intimate relationship. The tattoo peeking from her pale skin carried a mysterious aura, making her seem like a woman from another world. Her sensual charm held a fascination beyond mere sex, stirring both mind and body with excitement. Yuki's somewhat dark demeanor was part of her allure, yet also a reflection of deep inner struggles. For me, a powerless student, this relationship gradually turned into days of irresponsible sex. But as the end drew near, feelings began to stir inside me—emotions that could never go back. *This work is an excerpt from "Three Days of Endless Fucking with the Tattooed Single Mother Next Door in a Cheap Apartment, Her Cleavage Revealing Ink" (SKU: dvaj00637).
