Bent over a chair.

Shoko sat up and bent over the leather chair, gripping the armrests for support. She looked over her shoulder and saw Kenji was standing behind her with his mouth agape. She smiled at the thought that he was enjoying the view of her pear-shaped butt with her moist, puffy snatch peaking between her ample ass cheeks.

Kenji no longer had any guilt or **** on what he was doing because he accepted he was doing was for his science and thus for his marriage. He stood behind the young doctor and gripped her slender waist, nudging the tip of his cock between the wet folds of her pussy lips.

"That's it, Mr. Kataoka," Shoko cooed as he slowly pushed his cock into the warm embrace of her cunt, slick with load of his cum. "Fuck me, Mr. Kataoka."

"Yes, doctor," he groaned, enjoying her unbelievably tight pussy around his cock, and obediently started thrusting his hips against her upturn ass.

"Uh... Yes... uh... Mister... uh... Kataoka... uh... fuck... uh... me... uh!" Shoko grunted as Kenji accelerated his thrusts, pounding her harder and faster. Her huge tits swung violently back and forth as his loins slammed against her ass, causing ripples in her flesh.

"Doctor... I... I... think... I am..." he grunted, pulling her waist back against his hard thrusts to try to stuff even more of his thick, long cock into her warm depths. He wanted to cum but he did not want to stop fucking the beautiful woman that was not his wife. He did not want it to end but after several minutes of the examination room filled with loud moans and flesh slapping against flesh, he felt his balls tighten.

"Mr. Kataoka!" she cried out his name as an orgasm began to consume her. Her pussy convulsed around his invading shaft and that pushed him over the edge.
