Cum on her tits.

Hajime decided he could not pass up the opportunity to live out his sexual fantasy of cumming on a girl's tits, especially the massive tits Nurse Ai had.

"I... I... am..." he grunted.

"Cumming!" Ai finished his sentence as he pulled his cock out.

He quickly pinched the base of his shaft to prevent himself from cumming to early and squatted over the nurse's chest. Releasing his pinch, he let out an audible sigh of relief as he sprayed a thick stream of jizz on her breasts. The young nurse squealed in delight at the sensation of her chest being coated with sticky white goop.

"Very impressive, Tanaka-san," Dr. Sugimoto complimented, smiling at his still erect cock. "I would like to personally test the limit of your stamina and see what it takes to finally make you flaccid."

"Yes, doctor," he bowed his head, unable to hide his smirk.
