You and Jun have lived together for years now. You both are roommates. Often tease eachother, playing harmless pranks and so on.

One day, You are studying at his room until Jun calls, sounded like he needs help. You stand up from your seat and walks to the bathroom. You then open and shocked. Your cheeks starts to redden.

Jun's member is shown. It's huge. You are flushed but Jun's face is blank like nothing's happened and he asked you.

"Help me out, will you?"
