[Shimoda Nekomaru] Training Record of Yukari and Others ~ Mikami Kei’s Melancholy Extra Edition [RoniNgaka]

After his father Late Saginomiya Ryo's death, a handsome son uncovers a hidden photo album among his belongings chronicling the bound, sweating training of a busty woman named Yukari, now married as Mikami and working as a high school health teacher. Armed with his good looks, a single drop of an incredibly potent aphrodisiac, and the power of blackmail over women with established social status, he lures his father's former subjects back into submission. What unfolds is a relentless cycle of coercion and betrayal where flushed, full-breasted wives are bound, drugged, and broken for blowjobs, cunnilingus and forced sex, continuing a dark legacy of domination.
