Finn walked into the O’Connell house to find the lights on but no women. After quickly poking into their bedrooms, which contained some shopping bags but were otherwise empty, he found them in the hot tub drinking wine. Neither wore a swimsuit.
“Finn!” MacKenzie called when she saw him.
He waved and approached the side of the tub. He spotted an empty wine bottle on the side of the tub and from their happy expressions, they were feeling no pain.
“Ladies,” he said. “How was the shopping?”
“Amazing.” MacKenzie grinned at her mom who laughed.
“Really?”
“Mmm hmm.”
“So what happened?
“Nothing much,” Jenny said.
MacKenzie giggled.
“Get anything good?”
“Oh, yeah.” Jenny smirked, but then she and MacKenzie looked at each other and started laughing.
Finn pushed down his annoyance. He needed patience. Eventually, he’d learn everything.
“So get in,” Jenny said.
He raised an eyebrow. Why not? He started stripping right there by the side of the tub. He did his best to make a little show of it, but he wasn’t hard like he’d been the last time he’d undressed for the ladies. Still, they quietly watched until he was nude and then as he climbed into the tub.
“Ah...,” he said dramatically as he settled into the hot water. “So ... where were we?”
The women exchanged a few silent words before Jenny cleared her throat.
“Well ... we were talking while we shopped—”
“We did a lot of talking,” MacKenzie interjected.
Jenny gave her daughter a mock glare. “Like I said—we were talking while we shopped. And we decided on a few things.”
“Are you going to clue me in?”
“Well...,” MacKenzie began. “Mom wants to go out fancy again.”
“It doesn’t have to be burlesque,” Jenny said. “Just someplace we can get dressed up.”
“Okay.” He wasn’t sure where they could go that qualified.
“And we want you to start wearing sexy underwear,” Jenny said. “If we are, you should.”
“I can do that.”
“Good.” MacKenzie smirked. “‘Cause we bought you some.”
He chuckled.
“We went a little overboard,” Jenny said.
“Okay...,” he mused. That could mean a lot of things.
“And ... uh...” MacKenzie shot her mom a look before sipping some more wine. Then she swallowed hard. “Mom has one other request.”
“I ... um ... understand it might not be something you want to do,” Jenny said.
“But we bought the strap-on anyway,” MacKenzie said.
He tensed and forced himself to breathe normally. He had a pretty good guess...
“It’s the one thing I never got to watch,” Jenny explained. “As much as I wanted to. Mac’s father and Greg refused to do it in front of me. And I really want to see it.”
“Okay...” Finn’s ass was involuntarily clenching. “So you want to watch...”
“Mac peg you,” Jenny said.
He let out a long breath.
“You don’t have to,” MacKenzie said. “Not if you don’t want to.”
He nodded.
“But...,” Jenny said, “I’d really like to see it.”
“I ... I don’t know.” He let out a long breath and wondered where he could get his own glass of wine.
Fortunately, the women had the sense to not push Finn for an answer immediately. As he sat silently, Jenny drained her glass. She looked around for another wine bottle and then chuckled.
“I guess it’s time to go in,” she said.
“Yeah,” MacKenzie said. “I need to use the bathroom.”
“Going to show me what you bought?” Finn asked.
“Mmm...,” Jenny said. “The toys. Not the lingerie.” When she saw the disappointment flicker across his face, she added, “We’ll save that for our next night out.”
“Fair enough.”
“Meet you in the family room?” MacKenzie asked.
After a round of nods, they all got out of the tub. Finn got the hot tub cover on while Jenny gathered up the wine glasses and MacKenzie hurried inside. He snuck peeks at Jenny while they did. She had an amazing full ass, that looked even better when she bent to pick up a towel. What would it feel like to touch her? To caress that ass?
She wanted to watch MacKenzie fuck his ass. Maybe she’d let him fuck hers in return.
Did he want to suggest it?
Even at the thought, his butt clenched.
Jenny headed inside just before he finished tying the cover down. When he reached the family room, MacKenzie already had towels down on the couch.
“How are we doing this?” he asked.
“Mom and me on the couch. You in a chair.”
“Got it.” He brought in a chair from the kitchen and set it up in roughly the same spot Jenny’s had been the previous night.
A moment later, Jenny came back with a plain shopping bag. She and MacKenzie talked quietly before they sat on the couch and set the bag on the floor between them. Then each of them reached into the bag. Jenny pulled out a small oblong vibrator with some cords on it to a power supply.
“It’s a bullet vibrator,” she said. “It’s designed for focused clitoral stimulation.”
Then MacKenzie pulled a longer traditional battery-operated vibrator out, except this had an extra small protrusion.
“This goes against my clit,” she said, “while the rest is inside.”
“Cool.” Finn leaned back and began slowly stroking his cock.
The women turned on the vibrators and began to play with them. Jenny gasped and jerked when she first touched the bullet vibe to her clit, but then put it alongside her clit for less intensity. MacKenzie just buried hers inside her and held still. She breathed deeply and stared into the distance as she trembled with pleasure. They played for a couple of minutes before MacKenzie suggested they trade.
Finn sucked in his breath. Watching Jenny slide the vibrator into her pussy that had just been in MacKenzie’s pussy made his blood race. He stopped stroking himself so he wouldn’t come too soon.
Like before, the women played for a while. More than once, they looked over at Finn’s cock and gave him a lust-filled gaze.
Meanwhile, his eyes went everywhere. From their stiff nipples and the way their chests rose and fell with their ragged breathing. From the way their hands moved to the small jerks of their thighs as they found a new sensitive spot. He only wished he could watch it all at once.
After several minutes, Jenny set the toy she was using aside. She reached into the bag and pulled out a magic wand vibrator.
“Rechargeable,” she said with a smirk. “So no cord.”
He nodded like he knew why that was important.
She turned it on and placed it on her pussy. Then she sighed with pleasure.
