He shook his head.

Kenji leaned back on the chair and enjoyed the feeling of Nurse Chiha's huge tits squishing his thick cock.

"Are you close to ejaculating, Mr. Kataoka?" she politely repeated.

He shook his head.

She took it as a challenge and she continued to rub his shaft with her mounds of soft flesh.

After five minutes, she asked again and he shook his head again with a smile.

"How about now, Mr. Kataoka?"

"No, Nurse Chiha."

"Does it not stimulate you?" she wondered.

"Yes, it does," he nodded. "It feels very good. My wife never let me do this to her so I'm enjoying it very much!"

"Hmm, perhaps we should try another method," the young nurse suggested, removing her breasts from around his cock, much to Kenji's dismay. "Remember, you are suppose to ejaculate so we can have a sample of your sperm, Mr. Kataoka."

"Yes, nurse," Kenji bowed his head, embarrassed he was too lost in the erotic sensations to remember his purpose at the clinic.

"Which method would you like to try next?" she smiled.
