Inside her

Your not going to waste your cum in her throat so you pull her unwilling from your cock.
"Strip." You tell her, her frown changing to a smile as she stands up and obliges you, pulling her beautiful dress off over her to expose her body. All she's left wearing is a dark black silk thong which she slides down her legs as you examine her rather attractive breasts. "Bend over the desk" you tell her as you stand and kick off your boxers and slacks. She turns her head over her shoulder to look at you lining up behind her large tanned ass. You slap your hands down onto it and begin to knead it in your hands before pulling it outwards as you push your hard dick up against her wet pussy. You can't help but smirk at her wetness without you having to prepare her at all.
"Someone is eager," you say as you push your head into her body. By no means the tightest you've had but definitely tighter than you had imagined.
"Oh I am," she giggles as she widens her mouth as you continue to push into her. You're about half way into her when you begin to pull out to the head of your penis, at this point you push back in. Soon your hands are holding her small hips as your fucking her over your desk. Your body hitting against her ass causing it to shake in time to your rhythmic fucking. Over and over you drill her before you can't help but moan yourself to match the surprisingly, for such a civilized lady, loud moans of Mrs. Beltrami.
As her body begins to convulse from your constant pounding, you decide to join her in orgasm and ram all the way into her, she cry's out something in Italian as your whole cock is left twitching inside of her. Your balls completely emptying into her wet pussy.
"Woah," is all she manages after you pull out of her after a few moments and fall back into your leather chair.
"I'm glad the deal works for both of us," you remind her subtly that that wasn't just for fun, there was a reason. Or are you just reminding yourself?
"You really are better than my husband," she says still lying over your table her ass still in plain view for you. "it feels so wrong, but... I need to go." And with that she rushes up to put her clothes on. She hadn't even taken her ring off you note.
After she's left you pour yourself a drunk, one of the ones you save for important clients or for... Well moments like these you guess. Eventually you get dressed yourself and leave for your own home and bed, but unlike Mrs. Beltrami you don't share yours.
