Finn held still, his dick still hard inside MacKenzie despite having just come. He and MacKenzie watched her mom bolt toward the hallway. Then they turned and looked at each other.
“Wow,” Finn said.
MacKenzie nodded. “Yeah. Wow.”
“She came.” He was dumbfounded that she had, even though he immediately realized he shouldn’t’ve been surprised.
“Yeah ... we all did.” Then MacKenzie’s eyes widened. “But ... you’re still hard.”
He chuckled. “I can’t explain it either.”
She squirmed, gently rolling her hips. As she did, her pussy tightened on his cock.
“You want me to keep going?” he asked with a grin.
“Mmm hmm.”
He wasn’t too sensitive, and apparently neither was she. He started slowly, stroking in and out. She sighed happily and began moving her hips to meet him. Most of the time, they looked into each other’s eyes, but from time to time, Finn glanced toward the hallway entrance. It remained dark and empty.
MacKenzie’s orgasm built slowly and crested with just a cry and some shaking when she peaked. It was more of a small encore to the big orgasm she’d had before.
Finn’s was much the same. His cock twitched and a rush of pleasure hit him. Then his cock pulsed, emptying what was left after his earlier orgasm into his girlfriend.
He bent forward and kissed her. Lovingly, with more affection than heat. They exchanged another smile before he pulled out and they started to clean up.
They didn’t see Ms. O’Connell the rest of that evening. She remained in her room. MacKenzie gave Finn a kiss at the door before he headed home. He was so looking forward to when they could just spend the full night together. The university required them to live in the dorms their freshman year, but they’d already started talking about an apartment for the year after that.
As he walked home, he replayed the events of the night. Having Ms. O’Connell right there had been hot as hell, especially watching her come. It was too bad she’d gotten embarrassed at the end. But, hey, she’d actually come out of the shadows and joined them. And she’d done more than watch.
The more he thought about it, the more he was convinced that Ms. O’Connell was the right third for them. It didn’t bother him that she was MacKenzie’s mom. MacKenzie might go along with it, too. The question was, would Ms. O’Connell?
There was only one way to find out.
Finn arrived well before dinner the next day. He’d suggested to MacKenzie that they fix one of her mom’s favorite meals, tortellini in cream sauce, and she readily agreed. After a trip to the grocery store, they were well into the prep when Ms. O’Connell arrived home. When she joined them in the kitchen, she pursed her lips in amusement.
“What’s this?” she asked.
“Dinner,” Finn answered.
“I can see that. I was planning on the leftover chicken.”
“You’ll like this better.”
“Finn and I can have the leftovers for lunch tomorrow,” MacKenzie added.
“So what do you need me to do?” Ms. O’Connell asked.
“Open a bottle of wine?”
Ms. O’Connell chuckled. “I can do that.”
As she did so, Finn turned the heat up on the pasta water. Ms. O’Connell sat at the table and watched as he cooked the pasta and started heating the sauce. MacKenzie slid the garlic bread into the oven.
“So...,” Ms. O’Connell said after sipping some wine, “to what do I owe this pleasure?”
“We wanted to have an adult conversation,” Finn said, “and the best way to have one is to show we can act like adults.”
“Ah. Hence dinner.”
“Exactly.”
She smiled. “I could get used to this.”
“Well...” Finn paused in the cooking and turned around. “Maybe you could. I usually have the morning shifts. I could talk to my parents about just having dinner here every night.”
“But you’re already here so much.”
He shrugged. “My parents don’t mind, as long as I come home regularly. Mac and I could always hang out there, too.”
“When are your shifts?” Ms. O’Connell asked MacKenzie.
“I’m usually done by four,” she answered, “but sometimes I stay until Finn’s done.”
“Hmm...”
Finn turned back to the cooking pasta. “We can talk about it when we eat.”
“Sound good.”
It took another ten minutes or so to get all the cooking done and the food on the table. Ms. O’Connell didn’t offer them any wine, and Finn wasn’t presumptuous enough to ask. Instead, he settled into his chair across from her. They talked about their summer jobs at the pool, which had just started. MacKenzie found her job at the snack bar boring but liked her coworkers. As a lifeguard, Finn was anything but bored, but he also had to deal with kids who wouldn’t listen.
“The middle schoolers are the worst,” he said. “They just don’t seem to understand what ‘don’t run’ means.”
“I remember those years.” Ms. O’Connell’s eyes twinkled as she grinned at her daughter.
MacKenzie squawked. “I wasn’t that bad!”
“Only some of the time.”
“I was a kid.”
“And now you’re an adult.” Ms. O’Connell paused. Then she took a deep drink of wine. When she’d finished, she set the glass down and slid it slightly away. “And you two wanted to have an adult conversation.”
“Yes,” Finn said.
She gestured for him to go on.
“Last night you watched us in the family room,” he said, “and ... we liked it. And we want you to do it more often.”
Ms. O’Connell’s eyebrows rose only a little and she looked to MacKenzie, who nodded in agreement.
“You liked it too,” he continued. “Nobody’s getting hurt. So why not?”
Ms. O’Connell pursed her lips and thought for a moment.
“Moms aren’t supposed to watch their daughters have sex,” she eventually said.
“So? We’re all adults.”
“And it’s not like I’m thirteen,” MacKenzie added pointedly.
Ms. O’Connell’s face reddened.
“Huh?” Finn said. He furrowed his brow in confusion and looked from one woman to the other.
