She grabbed his shaft.

Kenji wanted to protest when Shoko grabbed his shaft without putting on latex gloves but instead let out a low moan. The young doctor smirked as she moved and rotated his thick, veiny shaft like a car's gear stick to take a closer look at different angles.

"How's your sensation?" she asked. But before he could answer she started stroking him. Kenji leaned back and grasped the edge of the table, clenching his teeth as he strained not to groan. "Relax, Mr. Kataoka. I need to properly examine you."

Kenji accepted his fate and already told himself that he was not cheating on his wife since the doctor and nurses at the clinic were medical professionals and there were only trying to help him get his wife pregnant.

"How often does your wife give you a handjob, Mr. Kataoka?" Shoko asked with a smile, noticing the emotional dilemma on his face. She continued to piston her small delicate hand up and down his thick meat pole that was abnormally bigger than the average Japanese man.

"She... uh... she never... uh... has," he stuttered.

Dr. Sugimoto suddenly stopped stroking, much to Kenji's chagrin. "Hmm, you managed to get another erection despite ejaculating early. Impressive," she noted. "How often does your wife give you fellatio, Mr. Kataoka?"

"Fellatio?" he asked embarrassingly.

"Blowjob," Shoko smiled at his naivety.

"Um...," he paused and bowed his head. "Never."

"Hmm," she said, grabbing his cock again.

"Doctor?" he gasped as she knelt in front of him.

Shoko grinned at Kenji and, locking her eyes with his, stuck her tongue out as she pulled his cock towards her mouth. He began to protest when she licked the tip of his cock.

"I need another sample, Mr. Kataoka," Shoko scolded him.

"Yes, doctor," he stammered before she ran her tongue along the underside of his veiny shaft from his balls to the bulbous tip.

Kenji wonder how much sperm his balls could produce while he stared at the beautiful doctor take his cock head into her mouth. He let out a moan when she twirled her tongue around his mushroom tip.

He let out another moan, but one of disappointment, when she pulled his cock out of her warm, moist mouth. She smiled at that.

"Please let me know when you are going to ejaculate, Mr. Kataoka," Shoko asked before wrapping her lips around the tip of his cock again.

He nodded and watched her wrap one hand around his thick shaft and the other cupping his balls. He groaned when she started to stroke him while fondling his testicles and sucking on his cock head. After several minutes Shoko stopped and slowly pulled his shaft from her mouth until her lips encircled the bulbous tip of his cock. She wrapped her long, thin fingers around his veiny rod and started to stroke while fondling his balls with the other hand.

Kenji tensed up.

She stroked faster.

"Uh... Doctor... Uh... I... Am..." he muttered as his balls tightened.

Shoko reached into her lab coat pocket to produce a sample jar. She popped his cock popped out of her mouth and aimed it into the jar a moment before jets of semen splashed inside the container. She had expected him to be like most of her male patients and be finished after releasing less than a teaspoon of semen but instead Kenji continued for almost a minute. The young doctor stroked his shaft and squeezed his balls, trying to milk more jizz from him. When she was satisfied that he could give no more she wrapped her lips around the tip of his cock, licked it clean, and gave it a playful kiss.

"You have no issue ejaculating multiple times. You just need to enjoy having sex again, Mr. Kataoka," Shoko smiled, impressed by her patient's virility. "I highly recommend that you and your wife stop having intercourse for two weeks and afterwards reduce the frequency of your lovemaking so you do not get tired physically and psychologically."

"Are you sure, doctor?" He knew his wife would be upset at such a suggestion.

"Do not think you are the first husband with this condition, Mr. Kataoka."

"Yes, doctor," Kenji bowed slightly.

"After two months," she said as she stood up and put a lid on the sample jar, "if you two are still having trouble conceiving please bring your wife in and my clinic will do our best to help her get pregnant."

"Domo arigato, Doctor Sugimotio!" he bowed again.

"Do itashimashite, Mr. Kataoka," Shoko smiled. She looked forward to see him and his wife in two months.
