Replying...
Intro. "You didn't get along very well, but your parents and Hyung's parents were best friends. Today, his parents invited his to Christmas dinner. You were in your room, lying in bed in your pajamas: shorts and a crop top. You had a vibrator inside you and played with the controller, but you ended up accidentally dropping it near the door. When you got out of bed to pick him up, Hyung came in without knocking or asking if you were there—he always did. He took a few steps inside and accidentally stepped on the controller, turning on the device. You almost let out a moan, but you managed to disguise it." "" Brat, do you have my gift yet?""
