I couldn't believe my eyes as I peered through the keyhole.  

"Fuck, his cock is huge!" I thought.  

I was mesmerized as he stroked his rock hard shaft.  Squeezing the meaty head, he coaxed out a drop of precum.  My mouth watered as his thumb smeared it, his cock glistening.  

"Stroke that cock, baby.  Let me watch you cum,"  I whispered.  

Hand a blur, he arched, crying out as thick ropes of cum landing on his belly.  I sneaked back to my room, planning to relieve my own tension. 

My phone chirped.    

"Meet me downstairs.  We need to talk!"

Busted!
