Being an inquisitive 12 year old, I was browsing through my Dad's stack of Playboy's when I spotted a plastic tackle box that was in the corner of my Dad's shop. Just as I opened the box I heard the front door open and knowing it was time for my Dad to get home I grabbed the first thing I got my hands on inside the box. I hurried upstairs and quickly ran into my room and hid the prize i grabbed from inside the tackle box into my jacket pocket. 

 As i got ready for school the next morning i grabbed my jacket and was out the door. I put my hand in my pocket and remembered the prize I put there the night before and pulled out a deck of playing cards and on the outside ofthe box were the words Naughty Nuns. I put the deck back in my pocket and trudged off to the school playground to meet my mates. The bell rang and off we went into the classroom and i put the deck of cards in my pants pocket and hung my coat up and went to my desk and waited for Sister Mary Vincent to begin with our first subject. Since my desk was in the back corner and i didnt like math, i decided to open the deck of cards and examine what was exactly on the Naughty Nuns cards. To my surprise the Nuns on the cards were naked except for the habits ! As I was looking over the deck I sprouted a boner because of the display of Nun flesh. What happened next was embarassing. Sister Mary Vincent told me to stand up and tell her why I wasn't answering her question.  I couldn't exactly stand because of my erection and was told to go stand in the corner until I could do as I was told. I grabbed the first book I could and walked to the corner. Sister Mary then went to my desk and saw the cards and quickly scooped them up and put them in her desk drawer. She then asked me what my punishment should be because of my refusal to stand and I said  that i should stay after school and have eraser and blackboard duty and Sister said good choice. After I did my punishment I went back to the classroom and saw Sister Mary looking through the cards and she was quite flushed and so was I. She got up and locked the classroom door and pulled the shade down and asked why I wouldn't stand when I should have. Well at this point I was beginning to get another boner and no where to hide it. Sister Mary then told me to unzip my pants and show her the result, which I did. Sister Mary Vincent spread the cards out on her desk and said to point to the card that aroused me the most, I looked at all of them and was extremely stiff by now and as I pointed to the card that I liked the best, Sister Mary grabbed my little man and began stroking it asking me if I enjoyed what she was doing and I stuttered yes Sister very much so as she smiled wickedly. I was feeling a strange sensation like never before as Sister Mary pulled my swollen dick and massaged my balls,  it was then my little fella began to throb and jerk as a stream of white goo erupted from my dick and Sister caught the result in her hand. I gasped and fell to my knees as the excitement ran through my entire body, never before had that happened  but wow that was a feeling I wanted to feel over and over and over again. Sister Mary Vincent wiped her hands off in a small towel and said that I was to stay and do eraser and blackboard duty until she saw that I learned my lesson. Sister said that there were 52 cards and that I should pick a new favorite tomorrow !
