I brought in Koko, a black-haired, slightly plump big-titted girl, to my room tonight. She loves Korea, and we had a lively chat about Shin-Okubo. She's not much of a drinker, but surprisingly enjoys soju and often drinks Chamsil. When I touched her stomach, it was all wobbly, so I started guiding her through some training with equipment, carefully hiding my ulterior motives. But her exposed panties and huge breasts kept drawing my eyes, making it impossible to stay focused. Eventually, Koko got tired quickly, so we gave up on the workout. As a penalty for losing, I made a rule that she'd have to kiss my cheek. When she lost, she hesitated and wouldn't do it, so I forcefully kissed her myself. After whispering sweet words like, "I like you, Koko. I want to see you more on your days off, I want to know you better...", she seemed turned on, her guard dropped, and she actively started intertwining her tongue with mine. When I undressed her, her perky, full ass and large breasts were revealed. Applying the vibrator made her convulse and shudder as she reached orgasm. When I offered my dick, she nervously but earnestly served me with blowjob and titty fuck. Upon penetration, her soft breasts jiggled wildly as she moaned lewdly, and I ended up shooting cum into her mouth. Though she initially resisted, once turned on, she transformed into an incredibly horny girl.
