"Please demonstrate, doctor."

Miki looked at her husband then to his big cock and finally at the doctor. If she wanted to learn how to please her husband to help their sex life and increase their chances of conception then letting Dr. Sugimoto demonstrate how to properly give a blowjob was worth it. "Please demonstrate, doctor."

"Please observe, Mrs. Kataoka," Shoko smiled as she brought the tip of Kenji's cock to her mouth. "Remember, you do not need to swallow the entire thing at once. Relax your throat muscles, like how a singer does it. If you feel like you are going to gag pull it out. There is no rush."

Miki nodded and intently watched the doctor suck in her cheeks as she twirled her tongue around his cock head. Shoko then shifted her head so that her neck was almost parallel with her husband's cock and slowly swallowed inch by inch of his thick shaft.

Kenji groaned appreciatively only to let out a disappointed sigh when the doctor suddenly pulled his cock out of her mouth with a loud slurp.

"Now you can try it, Mrs. Kataoka," the doctor smiled, pushing Kenji's saliva-coated cock towards his wife.
