Dr. Sugimoto's turn.

Hajime watched Ai stand up to allow Shoko kneel between his thighs. His eyes focused on her large breasts that she pressed against either side of his shaft -- he noted that the doctor's tits were more firm than the nurse's. She playfully alternated one breast to the other to rub up and down his veiny rod until he groaned, signaling he was about to cum. Releasing her breasts, she engulfed his glans and feverishly stroked his shaft with both hands.

"Sugoi!!!" the janitor cried out as he blasted thick wads of semen down the doctor's throat.

After Shoko swallowed the last drop of jizz she pulled out his salvia-coated erection from her thick lips. "Very impressive, Tanaka-san," she grinned as she stood up next to Nurse Ai. "You are still erect after ejaculating three times now. I would like to examine the limitation of your non-medicated virility."

"Of course, Dr. Sugimoto!" Hajime replied, bowing his head slightly at the honor.
