She breaks the ice

She laughs and says "You know if anyone walks in I'll probably loose my job John" "Not much I can do Doe with you on top of me and us tangled in these wires." Doe lifts her self up and rest back down on you letting out a moan. I try not to cum inside her. "Are you able to move Doe?" "I'll try John." She moves left and right trying to get untangled by my hard erection is keeping her in place. "I know you like this John" she says as she squeezes my ass with hand bound against me. "I don't think we are going anywhere until your cock is out of me John" Doe says dirtily. "And I can't lift myself off it". My heart pounds as I wonder where she's going with this. "Is this your first time John?" "Yes it is" "Well, enjoy this next part." She lifts herself up and drops back down my erection and moans "Oh John your cock is so large" she starts thrusting her ass up an down my cock. "Oh John Oh fuck me" I lay stiff on the ground as Doe takes my cock up her ass. "Oh John fill me Oh with your cum!" I can't believe my teacher is fucking with me. Her moist panties and insides running against my erection sending waves of sensation through my body. "Oh Doe your ass is so tight uh!" "Oh fuck me hard John!" I am soon able to thrust off the ground synchronizing with her bouncing. {Ohh OHHH JOHN OHH". I feel another wave of sensation and my load starts shooting into her ass as the same time as the thrusts. "Oh JOHN fill me with your cum!" It's starts pouring out of her crack soaking her panties and jeans and slipping out of them. Our thrust soon become a sticky slapping sound as my cock pull out of her ass. She lays back down on top of me. "Now lets see if we can get untangled John."
