Yes, after Bernie prods him for the truth

Bernie's long eyelashes went up and down over her deep brown eyes behind her big round glasses. "Did you want to let my mom watch?" she asked Gary.

Gary swallowed, looking at his naked girlfriend. His heart beat fast with excitement. "Um. What do you think?" he asked.

Bernie looked at Gary's face and posture. She pursed her lips and tilted her head, waves of damp curly brown hair sweeping her neck. "I think you want it," she said.

Gary blushed. "Um," he said.

Bernie laughed. "So am I right?" she asked. "You want Mom to watch you go up my ass?" She put a hand on her hip. "Truth, now, no hiding anymore."

"Yes," Gary said. He took a deep breath. His shoulders relaxed. "How about you?"

"Fine," she said. "Mom'll be really happy. Do you think you can stand it if she tries to direct us?"

Gary laughed. "Sure, I don't know," he said. "I guess I can tell her to ease off? Or you can?"

Bernie laughed. "Yeah, sure, probably," she said, rolling her eyes. "But this is Mom."

Gary shrugged. "Well, yeah," he said. "Okay then."

Bernie said, "I'll go get her."

Gary sat down. His heart thumped and his hard cock throbbed with anticipation. This wasn't the first time he'd been watched going up a girl's ass -- that was with Sharon, in front of Stuart's beach crew -- but this felt different. Better. Much better.
