Non-stop fucking.

The women had been fucked by patients before but none had the stamina approaching the superhuman level of Yoshitaka's. His erection remained granite hard despite cumming in all five of them and they were not sure if they could satisfy him enough to finally make him flaccid.

The coach's mind was clouded by feral instinct of fucking all of them to plant his seed in their wombs and he growled at the mass of soft feminine flesh on the bed. Ai let out a squeal when he effortlessly picked her up and impaled her on his cock. He sucked on her tits as he raised and lowered on his erection, ignoring her orgasmic cries until he finally came in her several minutes later.

Pulling her off of his cock with a loud audible slurp, Yoshitaka tossed her back on the bed and grabbed Chiha when he realized he was still painfully hard. He bent the busty nurse over the bed and slammed the full length of his massive cock into her tight cunt in one hard stroke. She grasped the bed linen tightly as her ass cheeks violently absorbed his thrusts. She came several times before he finally filled her pussy with his spunk.

"I need more pussy!" the coach demanded and grabbed one of the twins.

"How... how is he able to stay hard for so long and cum so often, doctor?" Chiha asked as she rubbed her sore pussy.

"I actually don't know," Shoko replied, watching Shizue being pounded from behind. "But I have my suspicions..."

Yoshitaka worn the girls out with the non-stop fucking. Covered in sweat they passed out on the bed with their pussies and mouths overflowing of semen and laid back with no resistance when it was their turn again to be fucked by the coach.

But then Dr. Sugimoto discovered when she was gulping down his cock what felt like a button at the base of his shaft between his balls and asshole and pushed it.

"GAAAAAHHHH!!!" Yoshitaka roared. Shoko barely had enough time to pull his shaft out of her mouth before his cock exploded like a geyser, drenching the women with a thick coat of sticky jizz.

The coach then collapsed to the floor, finally flaccid after hours of sex.

"Is... is he cured, doctor?" Yui wondered, as her twin licked her face clean of cum.

"Yes, he is," Shoko grinned. "Take a shower, girls, and I will look after Saitou-san."

"Yes, doctor!" the nurses giggled and walked out of the examination room rubbing their sore pussies leaking of cum.
