   Summary

   You've known Blue for years. Going over to his house for movie night has been a weekly occurrence since you met. Unfortunately, Blue gets called into work this time, leaving you home alone with his brother and his friend. Stretch and Cash. Both of which you have a raging crush on.

   Hopefully you can keep up with them.
