Minho

Jisung's best friend Yongbok took him to a party after he god bad marks on a test, and he knows that Jisung takes school seriously, and he wanted to lighten up the mood. You go there and you have a wonderful time. After a while, a good looking guy comes up to Jisung and winks at him

"I've never seen you here before. Mind if you tell me hour name, handsome?" He said in a flirtatious tone. Jisung looked at him and then blushed... A LOT... and spoke in a quiet tone

"I'm Jisung.."

he then looked down and realized that he had a boner and then ran in to the bathroom. As he got there he quickly took off his clothes and started jerking himself off. After a while he heard the door open. Apparently he forgot to lock the door. Well, what did you expect? It was the guy from before. Minho. Minho looked at Jisung with a smirk and then closed the door as he got inside.

"Don't mind me Jisungie~"

He said with a wide smirk

"Go on sweetie, touch yourself."

He said almost demanding.
