My teacher IV

After cumming he slapped my butt and scolded me. He said to see him after school. As I dressed I thought thank goodness I don't have to wake up so early tomorrow. My butt hole felt funny when I stood, but didn't think anything about it. The day finally ended and I went to Mr. Roberts class room. The door was locked and the blind was pulled down. Confused I waited a few minutes, then knocked. A couple of seconds later it unlocked, but didn't open. I opened it and walked in closing behind me and locked it. Turning around I seen the boy from the other day, naked and on his deck butt in the air. Mr. Roberts said to come over and strip. Walking around the desk I seen the boys butt was wet and his dick was still hard, which made me hard. When I was naked Mr. Roberts told me to get on the deck, ass up and for the boy to get down. Then he told the boy to get behind me and do what I taught you. He spread my butt and licked, pushing his tongue against my hole. I could hear Mr. Roberts telling him " that's it, just like that. I looked down between my legs and seen him stroking the boys dick and rubbing his chest. My legs began to shake as his tongue pushed its way into my hole. Mr. Roberts said " you better not cum early this time or I'll fail you. I closed my eyes and thought of the worst things I could. The boy replaced his tongue with a finger, probing slow in and out till it was all the way in me, then he twisted his hand. My whole body was shaking now and I couldn't catch my breath. After what seemed like an hour of madness I heard the boy grunting. I looked and seen him cum, sending his stuff flying under the desk. Mr. Roberts kissed him and licked his hand clean.
