Finn stood quietly, drinking in the sight of Ms. O’Connell. Her breasts were fuller and heavier than her daughter’s, but will the same nipples, all hard and plump. Her stomach wasn’t as tight as Mac’s and her flared hips were wider, which he figured was age as much as anything. She was still a MILF.
Literally, he realized. He could feel his blood stirring.
As he watched, Ms. O’Connell flipped a page in her magazine, and then another. Her breasts rose and fell as she breathed. Then she set the magazine to the side and eased into the tub. She smiled, very happily as she did.
Finn shook himself. He really shouldn’t be staring. He really should go home.
Besides, the best view was gone. While Ms. O’Connell’s breasts weren’t fully underwater, the lighting was completely different and there wasn’t much to see.
Reluctantly, he stepped back. He needed to get home.
To Finn’s surprise, by the time he got back over to MacKenzie’s in the late morning, Megan had already left. He found MacKenzie alone in the kitchen, half-heartedly eating a bowl of cereal. She gave him a winsome smile when he came in.
“Hey, Beautiful.” He gave her a quick kiss before sinking into the seat across from her. “How’re you doing?”
“Tired,” she said.
“Did you have fun last night?”
“Sort of.” She blew out a long, frustrated breath.
“What happened?”
“Not much. We talked a lot.”
“Ah.”
“Yeah.”
“So...,” he said, “you didn’t...”
She shook her head. I wanted to ... and I think she wanted to, too, but...” She sighed.
He nodded knowingly. “Couldn’t actually do it.”
She shook her head. “Chickened out.”
“Well...,” he said philosophically, “there’s always next time.”
“Maybe,” she said. Then she sat up a bit straighter. “I wish you’d been there. You wouldn’t’ve chickened out.”
He chuckled. “Maybe.”
She sighed and sagged back in her seat.
“They’ll always be other chances.”
“I dunno,” she sighed. “She’s gonna be gone all summer and then we’ll be off at college...”
“Yeah ... but she’s not the only woman out there.”
“The only one we both like.”
He chuckled. “They’ll be others.”
“Yeah, but...” MacKenzie sighed. Then she grimaced. “I know I should be satisfied—”
“But you’re curious.”
“Yeah. It’s just...”
“You don’t have to justify it to me,” he teased.
She chuckled. “No.”
“You won’t miss out,” he said. “We’ll figure something out. Besides, maybe things will work out with Megan before she leaves. We can always invite them over for a graduation party.”
That brought a smile. “Just the four of us.”
“Just the four of us,” he agreed. “Go hot tubbing and skip the suits.”
“Megan and I did that.” Her grin grew.
“I know. I saw, remember?”
She giggled. “Yeah, you did, didn’t you?”
“At least a bit.”
“We slept naked, too.”
“You did?”
She nodded, her grin growing, but then it fell. “We just ... couldn’t...”
“Take the next step,” he filled in.
“Yeah.”
“Well ... how about we go to your room and you can tell me all about the next step you wanted to do?”
She sat up straight. “While we...?”
“Of course!”
She grabbed her bowl and spoon and stood. “Let’s go!”
As soon as they had the bedroom door closed behind them, Finn pulled MacKenzie into his arms and kissed her thoroughly. One hungry kiss led to another, which led to him tugging her clothes off.
They moved to the bed, where he stretched out on his back. Already hard, MacKenzie only gave his cock a few quick strokes before she straddled him. They both sighed as she sank down on his cock.
“I love you,” he said as he held her hips.
“I love you, too.” She grinned and cupped her breasts, gently kneading them.
“So ... Megan.”
“Oh, God, Finn.” MacKenzie sighed happily and began to rotate her hips, grinding her pussy against him. “She’s so sexy.”
“I’ll bet,” he chuckled.
“And she shaves. She’s ... she’s beautiful down there.”
“So you got a good look?”
Mac nodded. “She ... uh ... might’ve ... uh ... showed off.”
“Showed off?” He chuckled. He flexed his hips, thrusting deeper into Mac’s pussy.
She shuddered with pleasure. “Yeah ... she’s, uh ... proud of her shaving.”
“And you didn’t touch.”
I didn’t know how!”
He gently stroked her side. “It’s okay, Babe. It’s okay. It’s not easy.”
“It is for you!”
He laughed. “Just how many women do you think I’ve seduced?”
Her cheeks pinkened, and she nodded.
“Just one,” he emphasized. He slid his arms up from her hips to her side, but then stopped. “Just one. Who’s amazing and incredible and sexy as hell.”
Her eyes twinkled. “You’re just saying that because we’re screwing.”
“Nope.” He pulled her down until their faces were close together. “I’m saying it because it’s true.”
Then he kissed her.
She sighed and gave in to the kiss. He began thrusting hard into her. She gasped and started pushing back. He kissed her again, and then relaxed to enjoy the slow, steady screw.
Finn leaned back and stretched against the couch cushion. He set his phone down — enough web surfing for now — and smiled down at MacKenzie. She’d stretched out on the couch and put her head in his lap, like she often did. Except this time she was reading on her iPad. She sensed his attention and lowered it.
“What?” she asked with a smile.
“I think we should do something.”
“Like what?” She grinned salaciously.
“We just did that,” he teased. “I was thinking of a bike ride or maybe going to a movie.”
“I kind of want to read.”
The door to the garage banged open. A moment later, Ms. O’Connell came in. She wore her gardening clothes and huffed in frustration.
“I can’t get the lawnmower to start!”
“Ugh,” Finn said as MacKenzie sat up.
“Finn, will take a look at it for me?”
“Sure. And...” He looked at MacKenzie and waited for her nod. “ ... if I can start it, how about I just mow it myself?”
“Would you? That’d be such a help.”
He smiled. “Happy to. That way MacKenzie can finish her book.”
“Ah.”
“Actually...,” MacKenzie said, “why don’t I help, too?” She smiled at her mom. “What do you need?”
