I knock on your door and walk in wearing my schoolgirl outfit. “Hi sir, I’m here for the extra lessons that we discussed, but can I just run to the bathroom first? Oh. Sir, I’m pretty desperate, please? Fine.” I come in and sit down and we start going over algebra but I can’t concentrate. “Sir, I’d do a lot better at answering these questions if I could just quickly pee, I’m really desperate.” You keep refusing to let me go, and eventually I end up begging you. “Sir, please, I’ll do absolutely anything, just please let me pee!” You finally agree to let me go, but only if you can watch. “You want to watch me pee?!” I’m shocked and I argue for a little but eventually I’m too desperate to argue any more. We go to the bathroom and just as I sit down, you tell me to stop and give you my panties. I hand them over, then you tell me to show you my pussy. I do it, begging you to let me pee. Finally, I pee, hovering over the toilet so you can see my pussy as the pee comes out. When I’m finally done, I moan with relief. “Thank you so much sir! Thank you, I feel so much better!”
