At dinner, they talked about anything and everything except what had happened earlier. Ms. O’Connell did explain why she’d come home early. The office’s computer network had crashed. The IT department expected it to be up in the morning. She bemoaned the work she’d be behind.
“So will you have to work late tomorrow?” MacKenzie asked.
“Maybe,” she said frostily. “Or maybe I’ll come home early. You never know.”
MacKenzie paled.
“Maybe you could call first,” Finn suggested.
Ms. O’Connell glared at him, but then her gaze softened and she slowly nodded.
“So,” she said, “do you have plans for tomorrow?”
“Shopping,” Finn answered. Though he had no idea where they were going to look for sex toys.
“For what?” Ms. O’Connell asked.
Finn hesitated and Mackenzie jumped in.
“Clothes,” she said. “I wanna get a new dress.”
“What for?” Ms. O’Connell asked.
“Dates,” Finn made up on the spot. “We want to have some nice dates, now that we don’t have school.”
Ms. O’Connell eyed him warily.
“In fact, we’re going out Friday. Dinner and a movie. Right Mac?”
Mac blinked in surprise, but caught his improvisation. “Yeah, we are! And I want a new dress.”
“You’re paying for it,” Ms. O’Connell said.
“Of course!”
She slowly nodded. “So ... Friday?”
“Friday,” Finn affirmed. “You’ll have the house to yourself.”
“Hmm...”
Finn suppressed a smile. He could see the gears turning even if he wasn’t sure what she thought.
Friday night found Finn standing by the couch in the living room and waiting for MacKenzie. He’d worn a classy casual black slacks and shirt to match what she promised would be a stunner. He held a single red rose, which he idly twirled in his hand. Even after all this time together, his heart still beat a bit faster in anticipation of seeing how sexy MacKenzie looked this time.
Ms. O’Connell similarly hovered nearby. She and Finn exchanged a smile, but neither spoke as they waited.
Then MacKenzie strode out and took their breaths away.
The black sheath dress hugged her body like a second skin. It had a plunging neckline that exposed all of MacKenzie’s cleavage down to the underside of her breasts. She’d accented that with a gold pendant that Finn had given her as a Christmas gift the year before. The bottom of the dress ended mid-thigh, exposing just a hint of lace of her thigh-high stockings.
Finn found it hard to breathe.
MacKenzie grinned at his reaction and then did a slow pirouette. The dress hugged her hips and ass so tight he could make out her g-string.
“Your panty is showing,” Ms. O’Connell said.
“Oh.” MacKenzie strained to look over her shoulder.
“Take it off,” Finn said.
“Now?”
“Yeah.”
“Uh—” But before Ms. O’Connell could finish her objection, MacKenzie had hiked the dress up, completely exposing her ass, and hooked her thumbs under the g-string.
Finn’s jaw dropped as she slowly peeled it down. His pulse raced and he couldn’t tear his eyes away. Belatedly, he realized that Ms. O’Connell was staring, too.
MacKenzie rolled the g-string down enough that she could push it to the ground. She stepped out of it and then smoothed her dress back into place.
“Better?” she asked with mock innocence.
Finn could only nod.
“That’s way too sexy for a movie,” Ms. O’Connell said. Her eyes remained fastened on MacKenzie.
“Yeah...,” Finn agreed. “Yeah, it is.” Then he remembered the rose and held it out. MacKenzie accepted it with a smile and then brought it to her nose.
He turned to Ms. O’Connell. “I apologize in advance for any loud noises later this evening.” He nodded his head at MacKenzie. “I may not be able to help myself.”
Ms. O’Connell laughed, deep and long.
“If I were you, I wouldn’t be able to either.”
Finn had picked a nice restaurant. The way MacKenzie looked, he wished he’d picked a really fancy one. Their waiter couldn’t stop staring at her every time he came to the table. MacKenzie blushed at first, but quickly became more amused than offended. Finn got a kick out of it too, and their service was top-notch.
After they’d placed their orders, MacKenzie leaned forward and smiled. Finn’s eyes fell to her cleavage, but he quickly met her eyes.
“I can’t believe you made me do that,” she said quietly. “In front of my mother!”
He laughed. “So?”
“But ... it’s my mom!”
“Did you hear her object?”
“No...”
“How could she?” He gave her a teasing smirk. “As sexy as you are tonight?”
MacKenzie smiled and rolled her eyes.
“Seriously. She likes looking at sexy women. Aesthetically, does it matter that you’re her daughter?”
“It should.” She didn’t sound convinced, though.
He shrugged. “A sexy woman’s a sexy woman. And you’re sexy.”
She blushed.
“I’ll prove it to you later.”
Her blush turned to a grin. “I’m looking forward to it.”
They arrived at the theater to find the movie had sold out. None of the other options looked interesting, so by mutual agreement they decided to head home. Having spent most of the time looking at MacKenzie’s cleavage, Finn was more than ready to go somewhere he could take that dress off.
They arrived at MacKenzie’s house to find the house quiet. The living room lights were on, and Ms. O’Connell wasn’t in her bedroom. Finn briefly considered doing naughty things with MacKenzie right away, but thought that maybe they should figure out where her mom was first.
“Maybe the hot tub?” MacKenzie suggested.
“Yeah.” Finn.
