No.

"I would like to but..." Kenji moaned. His wife rarely let him fuck her from behind and this was the one chance she did not say no because of the suggestion by the doctor.

"Then continue, Mr. Kataoka," Shoko smiled, knowing his impressive sexual stamina.

"Yes, doctor," he grunted and held onto his wife's tiny waist as he continued to thrust.

Miki mewled as her husband plow her from behind. She had always insisted they make love in the missionary position because she thought it would it increase her chances of getting pregnant and she could see her husband's face, whereas, the doggy style position made her feel like some barn animal in heat and not actually making love to conceive a child. However, she finally admitted to herself she now enjoyed having Kenji behind her.

"I see you are enjoying this position, Mrs. Kataoka," Shoko noted.

Miki nodded as the heat in her pussy built up.

"Good," the doctor smiled. "Now, Mr. Kataoka please reach under and grab your wife's breasts."

"Yes, doctor." Kenji did what he was instructed.

"Now pinch her nipples."

Miki let out a loud orgasmic cry when her husband pinched her erect nipples.

With his wife climaxing, he could feel his balls tightening, warning of his impending orgasm. He let go of her breasts and grabbed her slight hips so he could pull her towards him against his long, hard balls-deep thrusts.

Shoko could not help slide a hand down to her crotch while she watched Kenji violently pound his petite wife.

"Boku wa..." Kenji started to say before he was interrupted by his cock exploding in his wife's cunt. He kept thrusting as his cock spewed thick strands of semen into her womb.
