Bestfriends, are we?(bxb)

Matt and Max have been friends since they were in elementary school. Now continuing their studies in college, they are roommates.

I was just reaching my climax when the door opened and Matt walked in. I took my guilty hands out of the purposely white bedsheet with the speed of light. "I have told you to knock, a thousand million times skim. This time you have interrupted me from even having a release after this long fucking week!" I shouted on top of my lungs, ignoring his wide eyes looking at my grown shaft.
He jerked his head towards me and his eyes turned into a darker shade, or was I just imagining it?
he walked towards me without uttering a word. "What do you want NOW???!!" I sighed out. He sat on the bed next to my hardened dick and held it in his muscled hands in a tight grip. "FUCK!".
