"Why don't you put it in your mouth, Joy?"

You take the hint and start to flick your tongue over Mr Williams piss-slit, making him groan and shudder. Looking up at him, you slowly wrap your lips around the head of Mr. Williams thick cock, swirling your tongue around his spongy glans in your warm, moist mouth.

"Oh, Joy. Thats very good, but I wonder, can you take ALL of my cock into your mouth?" You waste little time and look up at him as you begin to slowly bob your lips up and down, sucking and licking him as his cock were your new favorite thing in the world. With each up and down motion of your head the tight ring of your lips dips lower. You close your eyes and concentrate on relaxing your throat muscles against the cockhead pushing at the back of your throat.

With a last gulp your mouth descends the final two inches and his cock slides into your throat. The fuzzy stubble of his pubes tickles the tip of your nose and you swallow to keep from gagging. Mr. Williams groans loudly and lays his hands against the back of your head. You remain like this for what feels like ages, but is probably only a minute or so, fighting back the urge to gag as the ring of your throat massages your principal's swollen glans.

"Oh my goodness, Joy, you are very good at this aren't you?"

At last, breathless and **** a little, you lift your mouth from his cock and smile, tears dripping from your eyes. You nod and give his hard cock a stroke.

"I wonder Joy, if I might return the favour."
