On her.

"He looked at me and the lust in his eyes were gone for a moment, enough lucidity for him to decide to pull out," Mari continued. "But he still need to cum so he stroked his penis until he ejaculated. He sprayed my breasts and belly like a fire hose with thick ropes of semen!"

"Has your husband ever cum on you before, Mrs. Osano?" Shoko wondered.

"No, when we have sex he just cums in me."

"How did it feel to be covered with your brother-in-law's semen?"

"It... it felt... exciting!" Mari answered.

"Exciting?"

"I just had the best sex of my life -- with my husband sound asleep a meter away no less -- and there was no risk of me getting pregnant! So when he stopped ejaculating I pushed myself up and knelt in front of his penis and..." Mari paused for a moment before continuing, "... I stuck out my tongue to lick the strand of semen dangling from the tip of his penis before taking his entire penis into my mouth."

"Oh!" Shoko gasped, surprised at Mari's shift from a demure, sexual oppressed housewife to a woman finally freed to express her sexuality.

Mari smiled. "When I finished sucking his penis clean I stood up and whispered, 'Thank you...' and then kissed him."

Shoko stopped recording and took some notes. "Did your husband find out that you had sex with his younger brother?"

"No, doctor!" Mari shook her head. "My brother-in-law quickly left the room after we kissed and I took a bath to clean myself up. My husband was still sound asleep when I joined him in bed."

"Have you spoken about the incident with your brother-in-law since then?" the doctor asked.

"No, we have not. We have both acted like it never happened..."

"Do you have any regrets of letting your brother-in-law have sex with you?"

Mari looked down at her lap before looking up to the doctor. "No."

"Again, I am not here to judge your marriage, Mrs. Osano, but to simply help you with your sex life," Shoko explained. "That said, I am glad that you were finally able to be satisfied sexually, albeit with your brother-in-law..."

"I... I..." Mari stuttered.

"If you would like, we can arrange an appointment with both you and your husband to see me," Shoko smiled.

"I would like that," Mari smiled back.
