On both of them.

"Where do you want to come, Gary?" Sonia asked. "In me? On me?" She raised her brassy voice in a laugh. "On both of us?" She grinned.

"On...both?" Gary said. He returned Sonia's grin.

"Come here, you," Sonia told her husband. She pulled him in for a kiss, then broke off to instruct Gary. "Come up here. Kneel there. Come on our faces, Gary," she demanded. She turned back to her husband, holding Josh close as she kissed him deeply.

Gary knelt behind Sonia's shoulder, stroking the big cock that had just plundered Sonia and Josh's butts, sliding his foreskin on and off the broad head, already oozing with clear fluid from the earlier action. Gary looked over his shoulder at his girlfriend Bernie, who watched from a corner.

Bernie was grinning broadly, looking amused at Sonia's scene directing. She nodded and waved Gary back to his job.

Gary turned back to the middle-aged married couple to give them his final service for today. Sonia's full lips worked on Josh's. He responded to his wife's earnest kissing by kissing back, though it seemed like he was going along with being Gary's cum target mostly to humor Sonia. Gary smiled down at them as he stroked himself. It was special in a funny way, knowing both a husband and wife, how each of their asses felt, hot and snug on his cock, squeezing tighter when they got off with Gary's cock inside them.

Gary felt his cock swell in his stroking hand. "Ohhh, gonna..." he said.

Sonia looked up. "Yes, Gary, yes!" she cried. Josh blinked and closed his eyes.

"AH!" Gary called out. His cock bucked, spurting pearly laces of sperm across Dr. and Mrs. Rubin's faces.

"Ha-ha!" Sonia laughed, grinning through a light covering of Gary's semen.

Josh chuckled, amused by his wife's enthusiasm. "Thank you, Gary," he said. "Thank you for all you've done for both of us." He swept the back of his hand over his cheek, wiping off Gary's seed.

"Yeah," Gary said, breathing heavily. "Yeah. Thanks. Me too."

Gary and Bernie left Dr. and Mrs. Rubin to their afterglow together and headed back to his place.

As they went through the door, Gary tripped on the threshold and staggered.

Bernie laughed. "Took a lot out of you?" she said. "Anything left for me?"

Gary laughed. "Yeah, they made me work hard," he said. "I think I better get a shower and a nap."

"You earned it," Bernie said. "It was wonderful watching you. If you're going to have sex with other people, that's the only way it works for me. I have to be there."

They kicked off their shoes at the front door.

"Gary, is that you?" a voice called from the kitchen.

"Mom?!" Gary called. He looked to Bernie, wide-eyed. "But...it's supposed to be four more days?"

Bernie shrugged and made a face. "That's what you told me," she said.

"Guess I better check in," Gary said. "How do I look?"

"Um..." Bernie said.

"Never mind," Gary said.

Bernie followed Gary into the kitchen of the Menard house.
