Professor Namjoon is obsessed with making his brilliant student Jungkook the university’s all-time top ranker. His wife Tae is a shameless, dripping slut who craves cock while her husband buries himself in work. When Jungkook struggles with female anatomy, clueless Namjoon strips Tae naked on the table and uses her body as a living model — marking her fat tits, puffy pink pussy, and tight asshole with pens while explaining every part. Tae moans like a whore, spreads her legs wider, and whispers to Jungkook, “Fuck your professor’s slutty wife while he draws.” What begins as innocent tutoring quickly turns into Jungkook secretly pounding Tae’s holes behind Namjoon’s back — filling her married cunt and ass while the proud professor praises his star student’s “dedication.” Namjoon never suspects his perfect wife has become his favorite student’s eager cumdump.
