Her fist jacked up and down his throbbing cock, her fingers tight around it. Sissy was staring at his flaring piss hole, her lips parted as she breathed with excitement. Karen, too, was now gazing at the head of her son's cock.

With a loud grunt, Richard came.

"Ohhhhh!" Sissy whimpered as the creamy come juice squirted high, her fist jacking wildly. A splash of jism spattered Sissy's blouse, right where a nipple protruded. Her fist beat frantically on his cock, making Richard squirt copiously until, as before, his stomach was coated with it. Sissy's fist, too, was smeared by his come.

Karen almost came, herself, as she watched her son spewing jism. She didn't know if Sissy did or not, but the woman was shaking.

Handing Richard tissue to clean himself, Sissy again perched on her high stool. She wrote something on her clipboard, but her knees were again wide. This time Karen could see all the way up the doctor's dress. She saw the woman's fuzzy pussy now, and when Richard had pulled his pants up and stood next to her, she knew he, too, was staring at Dr. Reed's cunt. More, she knew Sissy was aware of where mother and son were looking.

Sissy smiled at them and placed her clipboard on her desk. "Richard is a very healthy young man, Karen," she said, her voice throaty. "However, I'd like to see him at least once a week for a while."

Karen could see why. It was not for medical reasons at all. The next thing Sissy said confirmed it.

"Of course, you won't be billed for these extra sessions."

Sliding off her stool, her skirt riding up momentarily, Sissy pulled Richard against her body, her hands holding his face.

"You're a very good patient, Richard," she said. Looking directly into Karen's eyes, she placed Richard's lips on her tit. "Now, if you will, Karen, I'd like to speak with you later, in confidence."

"Of course," Karen replied, unable to keep the quiver from her voice. "I'm available anytime."
