Sexy Oppa's Friend

“Relax your body, Suyeon.” “H-How….” “Breathe.” Suyeon panted, her body stiff as a board. She trembled at the sight of Gihyuk, who had gone from “oppa” to a man in an instant. “Otherwise, I can’t do it right. Come on.” “I-I can’t.” She wasn’t a child anymore. There were far too many things she needed to be taught. “Don’t run. And don’t pass out either.” She’d already run away once before. Who was it that seduced him first, saying she wanted to be taught? So now, take it properly. Being a friend’s younger sister wouldn’t earn her any mercy.
