in class but out of mind

i was teaching my afternoon calculus class today and sitting at my desk grading papers when i felt a familiar buzz from my pocket. its been a running joke with jane that im secretly her sex toy, since shes such a control freak in the bedroom. so while mr smith asks questions up front, i slide my finger under the hem of my skirt to unzip my pencil case, grab jane's custom remote control and slowly lower myself onto it. the buzz starts low but builds, triggering more sensations with each tap on my phone. i keep one hand on the papers to steady myself as my other moves to adjust my bra and unbutton my blouse, feeling eyes on me from across the room. mr smith calls roll but i dont answer, lost in my own little world between jane's control and my naughty classroom
