Spin her around and give it to her

You spin Trish around in the cramped confines of the janitors closet and yank down on her tight black pants. You pull them just down past her buttocks before opening your own pants and freeing your urgently hard erection.

"I'm gonna show you what a real man feels like," you breath into Trish's ear as you yank the back of her white g-string sideways and push your raging hard-on between her legs. Trish moans as you lunge upwards, thrusting your hard cock into her moist cunt.

"Oh God!" breathes Trish as you hold her hips and begin sawing up and down in her cunt with your thrusting dick. You reach up with one hand and clutch at her ample breast, squeezing it through the lace of her bra.

"Oh Yes!" you gasp, pumping harder and faster against her shapely ass, both your hands now grappling her lingerie clad tits. You feel your balls churning as you thrust hard up into her and know that your orgasm is close. She moans as your fingers find her nipples and pinch them through her bra.

"Oh God!" moans Trish, pushing her buttocks backwards to meet your thrusting cock.

"Oh yes here it comes!" you cry, your hands fisting over her tits as your penis twitches and spurts, filling her pussy with you hot sperm. Your hips twitch and thrust a few times as you empty the last of your load into the gorgeous blonde and then you finally release her tits.

"Oh God," murmurs Trish one last time as you slip back out of her, her g-string snapping back into place.

Well it would seem the two of your have missed your medical examination, you'll just have to carry on to the first class of the day.
