Borderline

When Hwang Mok-yeon's friend-with-benefits Chae Sunhwa proposes a threesome, he's only mildly intrigued until he hears who the third is. His target? Eun Nanjo: wealthy, polite, and perfectly presentable...but, according to Sunhwa, hopelessly boring in bed. At first, it's just curiosity. But once the three of them are tangled in sheets, Mok-yeon finds he can't take his eyes off Nanjo...not even for a moment. And when he realizes Nanjo may be more interested in saving Sunhwa than claiming him, Mok-yeon makes a quiet, dangerous offer. He leans in and says, "I want you. Do you think you could spread your legs for me?" (Source: Lezhin Entertainment)
