Bend her over the desk

"Horny girls need to fuck, Ling," you say. "You know that. Bend over Gillian's desk and I'll give you what you need so very much."

Trembling with relief and resignation, she places her palms on the desk and presents her backside to you. Her ass leaves something to be desired but her long, glossy hair on her back and her huge tits pushing out at either side as she presses them against the desk makes her a sight to behold. You come up behind her, undo your pants, and rub your hard dick along her slit. She moans and quivers and sighs out something in Chinese. You work your dick between her swollen lips and slide it home, arching your back. Looking up, you see your professor looking like she doesn't know what to do at this point.

"You like to watch, Gillian," you tell her. "You LOVE to watch! You love to fondle your pussy and your tits while you watch me fuck another woman."

"Yes, Master," she agrees, a grin dawning on her face. "I love it!"

You put your hands on Ling's hips and start pumping. She shudders and clenches and coos.

"Say 'Me so horny!' Ling," you tell her. Her English is quite good, but you can't resist a good steriotype.

"Me so horny!" she declares as you fuck her. "Me so HORNY!"

Gillian's left hand is burried in her pants now as she leans heavily against her office door and looks hungrily at what you're doing to Ling.

"Rip off your blouse, Gillian!" you say, and she does with a cry, then squeezes her nipples hard and groans.

You reach forward and grab hold of Ling's jugs and pull back on them as you thrust your pelvis against her backside. She starts making animal noises. You're so close.

"Come for me, Ling," you pant. "Come hard. You too, Gillian. Come. Come. Everybody come!"

And come you all do, loudly and thoroughly and spectacularly.

Panting and sweating, you grin at the two ladies you just brought to orgasm, one without even touching her. Ling has her face on the desk and is looking at you deleriously from the corner of one eye. Gillian has sunk down to sit in front of the door and is looking up at you worshipfully. Life is good.

And then there is a knock at the door and someone urgently asking if something is wrong. Oh fuck.
