The latest installment in the Tuning Club staff's private training series, number 28! "I think it all started because of my father's sexual preferences." The protagonist once discovered adult videos secretly kept by her father, mistakenly believing what she saw was normal sex. Her first sexual experience felt somehow unsatisfying. Ever since, she's longed to experience the fantasies she's imagined—being tied up, tormented, seeking that sensation of letting go. In the end, this feels much deeper than ordinary sex... Who would've thought SM would captivate two generations of the same family?
