Hana was struggling with her English grades, so her mother arranged for Michael, a colleague, to tutor her privately. The lessons took place in Hana's room, creating a tense and awkward atmosphere. During one session, Hana accidentally spilled tea in frustration and hurried to clean it up. In her panic, her big tits brushed against Michael's crotch, causing his huge black cock to become fully erect. Shocked by its size and thickness, Hana is pressured into taking responsibility and ends up sucking his shiny black dick. Completely overwhelmed by the sheer size of his massive cock—nothing like her previous boyfriends—Hana becomes addicted to it. The story follows her psychological transformation and the escalating intimate relationship between her and Michael.
