Bend Mary over the desk

"You realise there's only one desk, but two of us," you point out to Mary.

"I guess that makes one of us the boss, and the other their sexy secretary," she replies with a glint in her eye.

"You're certainly looking very sexy," you observe.

"Oh, thank you, sir," she croons, "do you have any assignments for me?"

"I have a very special assignment for you," you reply. "Bend over this desk here and let me see your arse."

"Oooh, certainly, sir!" says Mary. She moves towards the desk, wriggles her bottom at you, then leans forward so that her enormous boobs are brushing the surface of the desk, her sexy arse pointing straight towards you.

"Good, good," you say, gently rubbing her buttocks, your cock instantly hardening as you prepare to take Mary from behind. You swiftly pull her clothes away to expose her butt cheeks in all their glory. You gently part them to get a better view of her butt hole, her pussy glinting with moisture just beyond it. Without wasting a moment, you pull your pants down to allow your hungry cock to spring free.

"Do you like your sexy secretary's bottom, Mr Lance, sir?" asks Mary.

"Yes, Miss Mary, I believe I do," you reply, allowing your cock to slide between her enormous fleshy buttocks. Mary moans in anticipation as you move your dick downwards so that its head is brushing her pussy lips. You lean forward over her so that your hands can reach her tits as you gently insert your enormous cock. Her pussy lips are tight but so wet, your dick slides easily through. Mary groans in delight and you feel her hard nipples poking against the palms of your hands.

You don't feel like being gentle this time, the urge to fuck is just too strong, so you push your dick all the way in, eliciting a gasp from Mary, and you instantly begin thrusting your hips.

"Uh, fuck," she says as you pound her tight pussy from behind, hard and fast on your new desk. "Uh, you're so big, uh, uh, mmm, yes..."

You maintain your hold on her breasts, enjoying the sensation of them trying to jiggle around in the rhythm of your insatiable fucking. You glance down towards your cock but all you can see is Mary's huge arse, her buttocks rippling slightly with each thrust of your hips. You feel yourself heading towards a climax but keep the pace up; Mary by now is incoherently panting and moaning in ecstasy as you roughly fuck her. You cum hard and urgently, your spunk shooting deep inside your wife's cunt and she reaches a climax at the same time. You stop thrusting so that you can both relish the sensation of your throbbing dick, which continues to spurt cum into her pussy for a good ten seconds or so.

After a while you withdraw your cock from her pussy, which instantly leaks cum all over your desk. You put your dick away, pull up her knickers and replace her clothing, ready to explore the next room.
