As they sat in the hot tub, Finn couldn’t come up with any other questions to ask Ms. O’Connell. He shook his head, and MacKenzie did the same.
“Good,” Ms. O’Connell said. “I’ve soaked enough.” She stood, the water sluicing off her back into the tub. ‘Put the cover on when you’re done.”
“Of course,” Finn said. He and MacKenzie sat quietly until they heard the door to the house close.
“Well ... that was interesting,” Finn said.
“Yeah,” MacKenzie replied.
“She knows we’ve caught her watching.”
“Mmm hmm. And she’s done it herself!”
“It?”
“Had people watch,” MacKenzie answered.
“Yeah ... I wonder what all she’s done.”
“You?” MacKenzie laughed. “She’s my mom.”
“Yeah...” He paused. “Are you okay with that?”
“With what?”
“That she’s your mom.”
MacKenzie grimaced and then shrugged. “Sort of.”
“What do you mean?”
“I mean, she’s my mom, and then she’s my mom.”
He laughed. “I kinda get that. It’s weird and hot at the same time.”
“Yeah ... but she’s just watching.”
“Still hot.”
MacKenzie grinned.
“Speaking of which...” He waggled his eyebrows and playfully leered at her.
“What are you thinking?”
“Your room. Leave the door open.”
MacKenzie broadly smiled. “Sounds great.”
Ms. O’Connell didn’t show up in the bedroom doorway to watch. Not when Finn licked MacKenzie to a screaming orgasm. Not when he moaned through his own orgasm while they screwed in missionary. Nor through her second and his second orgasms with Finn riding him cowgirl style. They’d made enough noise that Ms. O’Connell had to have heard them, but she didn’t come watch.
The next evening was much the same. They’d already had one round of sex in the afternoon while Ms. O’Connell was at work, so Finn wasn’t in a hurry to return after dinner with his own parents. When he arrived in the evening, Ms. O’Connell was watching a movie in the family room, so Finn and MacKenzie adjourned to her room. Despite two more rounds of noisy sex with the door open, Ms. O’Connell didn’t stop by.
Friday afternoon, Finn and MacKenzie went to an earlier show of the movie they’d missed the week before. They didn’t have any problem getting tickets this time and had a late dinner out afterward. When they got back to MacKenzie’s house, her mom was reading in her bedroom. MacKenzie started to tug him toward her own bedroom, but he hesitated.
“Let’s get in the hot tub.”
She paused and looked questioningly at him.
“Without our suits.”
She grinned. “Maybe she’ll join us?”
He grinned back. “Maybe.”
They grabbed towels and water and stripped in the family room. Then they headed out to the tub.
They waited about twenty minutes before Ms. O’Connell came out, though she was fully dressed. Her eyebrows rose when she saw MacKenzie’s bare breasts above the water, but she then smiled.
“I’m going to bed,” she said to MacKenzie “I left some stock I was making simmering on the stove. Can you please put it in the fridge before you go to bed?”
“Uh ... sure.”
“Thanks.” Her lips pursed into a devilish smile and she looked at Finn. “Have fun.”
He grinned back. “Oh, we will.”
After Ms. O’Connell went back inside, MacKenzie signed with frustration.
“It’s okay,” Finn said.
“She didn’t get in.”
“Yeah.”
“She didn’t even say anything.” MacKenzie arched her back thrusting her breasts forward and higher out of the water.
“Nope, but ... I think things are good.”
“Huh?”
He smiled knowingly. “She could just put the stock away herself.”
“Oh? Oh!”
“Yeah. She didn’t come out here to tell us about the stock.”
“So ... what do we do?”
“I think we get out and take care of the stock.”
They dried off but just wrapped their towels around themselves instead of getting dressed. After a quick kiss, they headed into the kitchen. On the way, Finn checked the hallway. Light seeped from under Ms. O’Connell’s bedroom door.
He smirked as an idea came to him.
“Make a little noise,” he told MacKenzie.
So they banged the pots as best they could without being too obvious, and let the fridge door slam shut, though that didn’t make as much noise as they’d expected. Hopefully, it was enough to make it clear that they were back inside.
Then Finn took MacKenzie’s hand and led her back to the family room. There, he pulled her into his arms for a kiss.
“So what are you thinking?” she asked when they pulled apart.
“I’m thinking we do it right here.”
MacKenzie smirked, and then kissed him again.
Their kisses quickly grew hot. Lips, tongues, hands caressing each other. Finn’s pulse raced.
He started feathering kisses on her jaw as he squeezed her ass. She moaned and kissed his mouth again.
They kissed and kissed until both were breathing hard. Finn was closer to the couch, so MacKenzie lightly pushed on his chest until he sat down. Then she sank to her knees in front of him.
She smiled up as she took his cock in her hands and gently stroked him. Still keeping eye contact, she lowered her head and kissed the tip of his cock.
He groaned as she began to suck.
She went slowly, almost languidly—gently teasing him with her tongue and lips. She wrapped one hand around the base of his shaft, stroking him as she bobbed her head.
He moaned again, louder this time.
She looked up and smiled with her eyes, his cock still filling her mouth.
“You’re amazing,” he said.
She chuckled, and the vibrations from her laughter ran through his cock and up his spine. He shivered.
“Oh, babe, you are amazing.”
