Finn and MacKenzie passed the time after dinner by streaming an old sitcom in the family room. He was actually amused. He’d had sex on the couch there more often than he’d watched movies or TV sitting there. The show was passably funny, thankfully, even if some of the humor was dated. What he wanted to do was turn it off and do naughty things with MacKenzie. But she wanted to wait.
So they waited.
And he hoped Jenny would get home before his curfew kicked in.
Thankfully, it was only ten o’clock when they heard a car pull up. They looked at each other—Jenny had driven to work that morning. But then there was a fumbling at the front door.
MacKenzie hopped up and let her mom in.
Jenny gave them a wide grin and then hugged MacKenzie. She waved at Finn.
“Gotta pee,” she said before she hurried down the hall.
MacKenzie looked out the open door. “You took an Uber?”
“Yeah!” Jenny called back.
MacKenzie shook her head and closed the door. When she returned to the couch, she looked apologetically at Finn. “She might be too drunk.”
He shrugged. “At least she took an Uber.”
They waited until they heard the toilet flush and then Jenny’s returning footsteps. She came in grinning but not stumbling, thankfully. Finn would’ve insisted she go to bed immediately if she had.
Instead, she gestured for Finn to slide over and then plopped down onto the couch between him and MacKenzie.
“Hi...,” she said with a huge grin. She looked first at Finn and then swiveled her head to smile at her daughter.
“So, how was your evening?” MacKenzie asked.
“Fine.” Jenny did the stare at one and then turned to stare at the other. “Just fine.”
“How was your friend?” Finn asked.
“Good. Really good.” Then Jenny got a devilish grin. “She brought somebody.”
“Somebody?” Finn asked.
Deep nods. “A man.”
He chuckled. “So it was a set-up.”
Jenny nodded again and turned to MacKenzie. “And he was ... fine.”
“Fine?” MacKenzie laughed.
“Mmm hmm. Good kisser, too.” Jenny turned back to Finn. “How come we never kissed?”
“You didn’t want to,” he said with a shrug.
“We should.” Another deep nod. “You licked my pussy.” Back to MacKenzie. “We should kiss if he licks my pussy.”
“Fine by me.” MacKenzie grinned and was on the edge of laughing.
“Is that what you want?” Finn asked. “Me to lick your pussy?”
Jenny looked at him. She looked him up and down. Then she put a finger to her lip as if in thought.
“Yes,” she said firmly. “I ... I want you to lick my pussy.”
He chuckled. “Well, then. Better get undressed.”
She lifted her hips and started tugging off her panties from under her skirt.
“What some help?” MacKenzie asked.
“Mmm. Yeah.”
Finn slid to the floor and continued to help Jenny get her shoes, skirt, and panties off while MacKenzie helped her mom with her top. Once Jenny was nude, Finn and MacKenzie quickly stripped as well.
“You have such nice tits,” Jenny said with a sigh as MacKenzie’s top came off.
“Well, so do you,” MacKenzie replied.
“Mmm.” Jenny was distracted by Finn pushing her thighs apart. “Mmm. Yeah. That’s it.”
He smiled to himself and began kissing her inner thighs. She squirmed, silently urging him on. He decided not to tease her and gave her one long lick from bottom to top.
“Mmm,” Jenny sighed. She cupped her tits and began caressing them.
MacKenzie shifted onto her knees on the couch next to her mom. “I wanna watch him do it.”
“Oh ... okay,” Jenny said. She held out an arm and welcomed MacKenzie as she nestled into her side. MacKenzie rested her head on her mom’s shoulder as her mom wrapped her arm around her. Both of them smiled down at Finn.
So he put on a show. He licked. He kissed. He sucked. He slid a finger inside and curled it while he sucked on Jenny’s clit. She squirmed and moaned almost constantly as he did.
He briefly looked up. Jenny’s back was arched, her head thrown back as she moaned. MacKenzie had pulled back just enough so they didn’t bonk heads. She grinned at Finn and then her eyes darted pointedly to her own chest.
Jenny had wrapped her arm around MacKenzie to hold her close. Now Jenny’s hand was on her daughter’s breast. Even better, she was actively squeezing it.
Finn smirked and then returned to licking Jenny’s clit. He was starting to learn her tells and so he also sucked on it and rolled it between his lips.
She moaned. He sucked more and she cried out and gasped. With a silent chuckle, he moved his head around in a circle while keeping his tongue firmly on her clit.
“Please...,” she moaned.
He kept licking.
“Please...,” she repeated.
“Are you sure?” MacKenzie said quietly.
Finn blinked. Jenny wasn’t talking to him.
“Yes ... I’m...” Jenny gasped. “Close ... so close.”
He needed to push her over the edge. He sucked on her clit again and curled a finger inside her.
That did it. She trembled and shook. She started to moan—but then the moan cut off as her body continued to convulse with her orgasm.
He kept going until she pushed back hard against him, clearly at her peak. After a few more licks, she collapsed back. Aftershocks continued to roll through her hips and thighs as he sat back and looked up.
And froze in disbelief.
MacKenzie and her mom were passionately kissing, tongue and all. Their hands roamed all over each other’s bodies. Jenny’s body was flushed and covered in sweat, but she didn’t let up as the last few aftershocks rose up.
He sat back, stunned.
They broke their kiss. Jenny panted for breath. Her eyes had gone glassy, her smile loopy.
“I need you.” MacKenzie’s lustful gaze could’ve melted steel.
Instead, it made him hard.
“On your knees and turn around,” he ordered.
He’d expected her to slide to the carpet so he could take her doggy-style while she braced her upper body on the couch. Or maybe better, her mom’s legs. But she didn’t. She remained kneeling on the couch cushions and bent her body over the back of the couch. Then she spread her legs, reached between her thighs, and opened her pussy.
