Richard shoved his hands out as if reaching for Sissy's swelling tits. Karen watched, more interested than surprised, as Sissy brought Richard's shoulders forward, causing his outstretched hands to cross. Her gaze followed her son's hands, and saw them brush over Sissy's tits. She thought she saw the woman tremble slightly.

"That's good, Richard," Sissy said, her voice suddenly quite low, a throaty sound. "Now, lie back and let's see what's going on in your tummy."

Karen watched Sissy probe her son's stomach in a professional manner. Then when she began to unbuckle Richard's pants he suddenly grabbed them.

"Hey, fella," Sissy grinned. "You're not turning bashful on me now, are you?"

Karen knew why her son grabbed his pants; his cock was still hard and he didn't want to have it exposed. There was a playful tug of war between Sissy and Richard, with Sissy tickling him, making him giggle and squirm.

At the right opportunity, Sissy jerked Richard's pants to his knees. Richard flung an arm over his eyes bashfully as his cock reared up in throbbing hardness.

"You don't have anything to be bashful about, Richard," Sissy said, her voice unmistakably husky.

The woman's long fingers moved up and down his thigh in a caressing manner, and it seemed to Karen that the woman gazed hungrily at his upstanding cock. Karen found that she was becoming aroused, her cuntjuice seeping into the crotch of her panties. Her eyes were glowing as she gazed at her son's hard cock and the way Sissy stroked her hand up and down his thigh. Karen felt heat between her legs, and squeezed them tightly. She was leaning forward slightly, watching the way her son's cock jerked. Sissy was standing on the opposite side of the table, facing Karen. Sissy glanced at Karen, and the two women stared into each other's eyes for a long moment. There was a tense atmosphere in the office.
