The last gong had sounded and school was out and most of the pupils had left for home, except a for few pupils wondering around like me... Suppose we all had our reasons, yes I really had mine, meeting Shelly behind the shed like we had done many times before...There I was looking and looking around but no sight of Shelly...Thinking yes Billy you have been let down by Shelly... When suddenly there was a shout from behind me...Billy...Billy...I turned around expecting to see Shelly...But to my surprise, it was the Headmistress Mrs. Suckaby... Ah no I said to myself, " What have I done wrong again..." There she was calling me with the wave of her hand for me to report to her...Slowly I trundled with my school satchel over my shoulder in her direction...Just wondering was it going to be another six of the best with her cane for something I was supposed to have done wrong again...The closer I got to her she shouted out hurry up I don't have all afternoon...Finally there I was standing at attention in front of Headmistress Mrs. Suckaby...Looking at me she blurted out that is how I like to see pupil Billy standing at attention when you talking to me...Still wondering what was she going to chastise me for, and knowing that my butt was still bruised from the beating she gave me last Friday afternoon... Mrs. Suckaby looked at me with another of her stern looks and looking over her dark rim glasses which were breached on her nose...Billy, she said, " Is it true that you and Shelly were going to meet at the back of the shed after school..." No...No...I muttered, and wondering how did Mrs. Suckaby know...You sure Billy, don't lie to me, Billy... Now trembling at the knees and stuttering as I tried to answer Mrs. Suckaby...At that moment Mrs. Suckaby burst out laughing and said: " I really had you worried Billy..." Sighing with relief I thought I had escaped the punishment of Mrs. Suckaby...Turning around and walking a few steps...Mrs.Suckaby screamed out, " Where are you going, Billy..." Turning around and staring at Mrs. Suckaby and her staring at me...She said so you need to be disciplined again...Looking at her with my steely eyes, she said you need to have a lesson about the birds and bees...so follow me...So in the direction of the shed we walked... Her leading the way and me feeling like a sheep...Open went the door, in we both walked...So this is were you and Shelly practice the birds and the bees...No no I replied, don't lie Billy and at that moment she grabbed hold of my crotch squeezing it with all her might and me tearing at my eyes, Mrs. Suckaby looked at me sternly and said so this is your and Shelly's hide out...No no I replied...At that moment down went my shorts and there I standing and my cock pointing at the ground, Mrs. Suckaby took hold of my balls in her hand...Now you will see what I do to liars like you...Pulling on my balls slowly she dropped to her knees and into her mouth went one of my balls and the other still in her hand she started to bite on my ball....Out of her, one hand went my other ball and she started to fondle with the shaft of my cock...Moving slowly with her nails causing a tingling feeling, finally at the head of my cock, she grabbed hold of my cock between her fingernails pinching into my cock head... causing my eyes to tear even more...Up she looked and seen that there were tears running down my cheeks, she released my ball from her mouth and muttered so I finally made Big Boy Billy Cry...Haha, she said...Stop crying, Billy...At that moment she started to masturbate my cock up and down went her two hands...causing my cock to erect in front of her eyes...My cock staring at her eyes and her hands gathering speed and it wasn't long and she had a face full of warm sticky cum...Wiping it with her fingers into her mouth went her fingers all covered in cum...Finally, her face was clean, up she stood up before pulling up my shorts...Looking at me Mrs. Suckaby said," Surely better than Shelly..." Looking at Mrs.Suckaby I said pity it is only half a lesson...Mrs.Suckaby slapped me in the face and said lessons are only 30 minutes so see you next week...Out of the shed, we both walked...
