It was thin, silver and had a very small face. A girl's watch.How did that happen? I though. I don't remember taking it off at anypoint today."David, ...ay attention!" I heard my teacher shout.It was then that I realised something else, something worse. I quicklyasked to go to the bathroom and was once again sprinting down thecorridors to the nearest toilet. I entered a cubicle and locked thedoor, ripping down my trousers. I knew it! I lifted my shirt to reveala lacy pink thong encasing my cock!. I didn't have time for romance but I wanted to show a little flair so I rolled my tongue around his head and caught a drop of pre-cum on the tip of my tongue in one deft motion. I marveled at the taste, long grain rice and marscapone maybe, and moved onto the next cock. Harold had as much girth around his cock as he did his belly, a fat sausage that about split my jaw to fit inside. On the other hand, it was only about six inches so fitting it down my throat was no problem, and speaking of the. I pulled up my pants and ran downstairs trying to hide my boner. My sister was at the door she had just finished shopping with her friends. She was looking hotter than usual she had red lipstick on her big plump lips and she was wearing a short skirt with leggings that had buckles fit for a whore. Her tits were hanging out in a white tank top. She gave me a hug for letting her in and I winced as my boner went right up against her pussy. She didn’t say anything which was weird because I was. I was experienced at one legged showers. I dried off and put an ace bandage on around my knee. I dressed and went downstairs for breakfast.My day went faster than I expected. I did my exercises for ten minutes after breakfast. I did homework for 50 minutes. I used the continuous passive motion (CPM) machine for two hours. I did more homework. I did my exercises followed by lunch, more homework, exercises, homework and another 2 hour session with the CPM machine. It was after three o'clock.
