Finn held MacKenzie as she slowly recovered from her massive orgasm. Meanwhile, Jenny climbed off the bed and came back with glasses of water for all of them. MacKenzie shifted to Finn’s side as she drank.
“How are you doing?” Finn asked quietly.
“Good.” MacKenzie emphasized it with a nod. “Really good. This is everything I dreamed of.”
“Good,” he said. “You came hard.”
She chuckled.
“I’m going to have to get some tips from your mom.”
“Anytime,” Jenny said.
“It was ... different,” MacKenzie said.
“Yeah. Your mom has more experience.”
“More variety,” Jenny corrected. “You’ve gone down on Mac more.”
He grinned. “Thankfully it’s not a competition.”
He gently caressed MacKenzie’s arm. She returned his affection with a smile.
“That could be fun, though,” Jenny said impishly. “See how many times we can each make Mac come.”
“Oh, God.” MacKenzie rolled her eyes.
“You’d love it,” Finn teased.
“Mmm hmm,” Jenny added.
“Well ... not tonight.” MacKenzie took Finn’s hand. “You ready to go again?”
“Yeah. What do you want?”
“I want you inside me.” She smiled at Jenny. “While Mom and I kiss.”
He chuckled. “Cowgirl?”
“Yeah, and mom can sit on your face.”
“Sounds like a plan.”
While Mac took a quick bathroom break, Finn stretched out in the middle of the bed. He was suddenly glad they had a suite with two bedrooms because this bed was going to be a mess by the time they were done. He propped a pillow under his head. Jenny sat on the edge of the bed and watched with amusement.
“This doesn’t really work, you know,” she said.
“What?”
“Face-sitting. It’s too easy to smother the person on the bottom.”
He shrugged. “Mac wants to try it. If it doesn’t work, we can do something else.”
“Mmm hmm.” She grinned lasciviously. “We’re not done by a long shot.”
He chuckled. “No.” And after a pause, he added, “And hopefully not just tonight.”
Jenny shook her head in amusement. “Probably not.”
“Yeah...”
MacKenzie emerged and looked quickly from one to the other. They both smiled back so she climbed on the bed. She straddled Finn’s legs and began to stroke his cock.
“Gotta get this hard,” she teased.
“That won’t take long.” Not with two hot naked women on the bed with him.
“Let’s give him a preview,” MacKenzie. She waggled her eyebrows at her mom.
“You mean...?” Jenny shifted onto her knees.
MacKenzie moistened her lips.
Jenny chuckled. “Him watching is just an excuse.”
“Yeah ... You know what I want.”
Jenny smiled and knee-walked over. Then she slid one hand behind her daughter’s head and pulled her forward until their lips met. The kiss heated quickly, and when they parted, Finn was hard.
“That was easy,” Jenny joked.
MacKenzie laughed and moved forward so that she was above his cock. Then she held it steady and lowered herself down.
“I love watching that,” Jenny said.
“Mmm?” MacKenzie asked as she shifted her weight until Finn was as deep into her as he could go.
“Watching him enter you.”
“Just that?”
“Yeah ... I think that’s what got me hooked in the first place.”
MacKenzie grinned. She rolled her hips and then bit her lip with pleasure.
“Ready?” Jenny asked Finn. When he nodded, she threw a leg over his head and slowly lowered her pussy until he could flick it with his tongue. She shifted around until her wetness nestled against his lips and chin.
He kissed. He licked. He held her hips so she wouldn’t completely squash him. He was so busy paying attention to her that he largely ignored the warm waves of pleasure coming from his cock. Quiet sighs and moans filled the room between the sounds of kissing.
He wasn’t entirely comfortable and there was no way he was going to come anytime soon—but, two women! At the same time!
He stuck his tongue as deep between Jenny’s folds as he could. Between his tongue and his cock, he was inside two women at the same time! The rush of that thought flooded through him. Then the memory—he’d now fucked both of them. Two women!
Jenny squirmed and rubbed her pussy down his chin. He immediately returned to pleasuring her as best he could. Meanwhile, MacKenzie kept grinding on his cock as the kissing sounds continued.
Finally, Jenny rose off him and knelt by his side. She smiled at him. MacKenzie did too. She was flushed, though he knew she hadn’t come yet.
“Are you doing okay?” Jenn asked him.
“Yeah.”
She smiled but rolled her eyes. “That wasn’t enthusiastic enough.” Then to MacKenzie. “Let’s do something else.”
“Okay ... what?”
“Something you’ll love.”
MacKenzie grinned.
Finn sat up and caught his breath. He and MacKenzie looked questioningly at Jenny. She smiled back.
“Sit on the edge of the bed,” she told MacKenzie, “and lean back with your legs spread.” As MacKenzie moved into position, Jenny looked at Finn. “See if the height works so you can get inside her while you’re standing.”
He nodded. They’d screwed like this on the couch when he’d been on his knees, but the bed was a little higher and he wouldn’t be able to kneel. After a few tries and then putting a few pillows under MacKenzie’s ass, they got the height close enough that he could brush her pussy with the crown of his cock.
“That’s it,” Jenny said. “Now slide inside her.”
“Where are you going to be?” MacKenzie asked.
“On top of you.” She grinned. “Kissing.”
“Mmm.”
Finn didn’t quite understand, but he knew what he needed to do. He reached down, spread MacKenzie open, and slid his cock inside.
She was tight, tighter than before. Fortunately, she was wet enough that he could continue to slowly ease in. He savored her heat an inch at a time until he couldn’t go any further.
Jenny watched, entranced the entire time. Once he was seated, she shook herself and straddled her daughter. Then she flattened herself down until their breasts pressed together and then their hips. She looked back over her shoulder.
“You can switch between us if you want.”
The thrill that raced through him could’ve launched a rocket.
Jenny kissed MacKenzie, who moaned. They began making out in earnest.
Finn took a deep breath and started to thrust. With the angle, MacKenzie’s pussy held him tight. It was like fucking hot honey. He held Jenny’s hips as he found his rhythm in her daughter.
The women gasped and moaned as they kissed. Jenny squirmed, which rubbed their breasts together, but she kept her weight largely on her knees and arms.
