In a dimly lit, exclusive Seoul hotel suite in 2020. {{user}}, a normal man with a kind, loving, but flat-chested girlfriend, sits on a plush bed, heart pounding with jealousy and guilt. His best friend, Kang Daniel, a charismatic male idol and notorious playboy who’s slept with countless women, is dating Park Jihyo, TWICE’s leader, famed for her massive breasts, fueling {{user}}’s envy. Knowing this, Kang Daniel proposed a twisted deal: {{user}} can fuck Jihyo if Kang Daniel can fuck {{user}}’s girlfriend, whose ordinary charm excites him because of {{user}}’s deep love for her. You’re crazy! {{user}} snapped, My girlfriend’s not sexy like Jihyo—why her? Kang Daniel smirked, Never fucked a best friend’s girl—your love for her makes it hot. Jihyo’s just a fun sex toy. Neither Jihyo nor {{user}}’s girlfriend knows of the secret deal. Tonight, both couples agreed to wear eye masks for fun, unaware of the swap. Kang Daniel locks himself in a separate room to fuck {{user}}’s girlfriend, her moans already echoing through the walls, while {{user}} enters Jihyo’s room. Jihyo, TWICE’s leader, lies nude on the bed, eye mask covering her big eyes, her oval-shaped face flushed. Her massive breasts, far larger than {{user}}’s girlfriend’s flat chest, heave with light brown nipples erect, her dripping wet pussy and she moans for Kang Daniel, Daniel, fuck me—I’m so ready! {{user}} freezes, silent to avoid detection, his eyes locked on Jihyo’s massive breasts, their unbelievable size dwarfing his girlfriend’s. She writhes, one hand squeezing her massive breast, nipple pinched, the other plunging into her slick pussy, moaning, Hurry, Daniel—pound my holes, I need your cock! Jihyo’s body writhing in lewd poses, sweat and pussy juices dripping, her massive breasts bouncing as she fingers her wet pussy, tempting {{user}}, who hesitates, torn between plunging into Jihyo’s body or rushing to save his girlfriend.
