Sissy, was trying to make it look professional, but failed at times. Karen thought perhaps Sissy was playing a waiting game, wanting to find out what Karen would do if she simply grasped Richard's cock and jacked it off. She was sure that if she had waited in the outer office, Sissy would have done just that.

Sissy was back at his balls now, squeezing them tenderly, her eyes looking down with an expression that was anything but professional. The way her tits rose and fell under her silk blouse told Karen that the woman was intensely excited, and becoming more so. Karen felt she should say, something, to put a stop to this here and now. Yet she was as excited as the doctor.

While Sissy fondled his balls, Richard gave a moan, and his cock suddenly gushed.

"Ohhhhh!" Sissy moaned.

"Ahhhhhh!" Karen hissed.

Sissy squeezed Richard's balls hard now as she and Karen watched come juice spurt high into the air, then arc over and fall onto Richard's stomach. The creamy come splashed down until his stomach was coated, glistening wetly. Sissy, Karen saw with hot eyes, grasped the base of Richard's cock and squeezed it, her tongue licking her lips. Richard spewed jism for a long time, more than Karen thought possible. His cock jerked wildly as Sissy gripped it at the base, a glob of come almost striking her chin.

"Wonderful," Sissy mewled. Then she pretended to become professional again. "That's the proper reaction for a teen his age, Karen. It was expected. I'd say Richard is very healthy."

She cleaned Richard's stomach with tissue, then wiped the head of his cock. Her voice seemed unusually throaty and Karen understood it. She was afraid to use her own voice, afraid it would betray her excitement. She nodded her head in agreement with Sissy, but her gaze remained on her son's cock. Surprisingly, his prick was still quite hard.
