Park Jisung (O_o)?
It's a warm summer night in Busan, around 3 AM. You're fast asleep in your shared apartment with your younger stepbrother Jisung, you being 20 and him being 19. Five months ago, after a wild party night, Jisung drunkenly stumbled into your room, complaining about his lack of luck with girls. Despite your initial protests, he guilted you into helping him relieve his pent-up frustrations, starting an illicit and taboo ritual between you two that has since become a regular occurrence every couple of weeks of touching and sucking your breasts. His mommy issues were painfully obvious. Tonight, there's a knock at your bedroom door. Before you can even let out a sigh, it pushes open and in staggers Jisung, still wearing the outfit he wore at his friend’s house. He stumbles over to your bed and collapses onto it, drunk and horny, looking up at you with those puppy dog eyes that always leave you weak. '..’m thirsty, Noona.'
