Finn sat in the hot water, his mind racing a million miles a minute. The problem wasn’t that he couldn’t think of other things the three of them could do. He had dozens of ideas. The problem was—which ones would the ladies like? And more importantly, would any of them drive Ms. O’Connell away?
Unfortunately, both MacKenzie and her mom were waiting for him to say something. The corners of Ms. O’Connell’s mouth turned up in a sympathetic smirk.
“Well...,” he said, “you could direct. You know, ask us to move into positions that help you see better.”
MacKenzie’s mom nodded.
“Or ask us to do stuff. You know, if you want to watch me lick MacKenzie, I’d be happy to.”
“You’d be happy to, even if I didn’t,” Ms. O’Connell wryly observed.
He shrugged. “She does taste good.”
“Mmm, I find it’s more about her reaction than the taste.”
He shrugged, rather than reply. He didn’t need to state the obvious—that he’d only tasted one pussy, and was eager to taste another.
“You could also use your toy,” MacKenzie blurted.
Her mom blinked. “You know about that?”
MacKenzie blushed and quickly looked away.
“I see.” Ms. O’Connell let out a long breath. “Did you at least clean it before you put it back?”
“Yes.”
“Well. Okay. You really should get your own. You’re eighteen now.”
“We’ll look for one,” Finn interjected. “But if you want to use yours while you watch, we’d enjoy that.”
Ms. O’Connell turned her attention to him and smirked. “I’ll bet.”
He shrugged and grinned good-naturedly. “That’s part of the fun for us.”
“Watching me?”
“Knowing that watching is turning you on.”
She chuckled. “Well, I suppose that makes sense.”
“So ... maybe after we get out.”
Ms. O’Connell grinned. “That could be fun.”
They soaked for a few minutes more, with each of them getting a bit restless. No one spoke about what they’d planned next. Instead, they talked about possible dates for Finn and MacKenzie. When they hit a lull in the conversation, Finn suggested that maybe it was time to move to the family room. Both women smiled and nodded agreement.
While Finn closed up the tub, MacKenzie and her mom dimmed the lights in the family room and spread towels on the couch. When he walked in, MacKenzie had settled onto one side of the couch. She smiled at him and parted her thighs.
“Where’s your mom?”
“Bathroom. And then getting her vibrator.”
Finn grinned. “So ... should we wait?”
“Mmm...”
He sank to his knees in front of her. “I’ll still be going when she gets back.”
MacKenzie grinned and spread her thighs wider.
He chuckled and began by kissing her inner thighs. She squirmed and then sighed as he worked his way up. Her mother returned just about the same time as he reached her pussy and began to lick her clit.
“Already started?” Ms. O’Connell mused as she sat down.
“She can come more than once,” Finn said between licks.
“Oh, I know.” Ms. O’Connell leaned back. Her eyes met Finn’s and she smiled.
He returned to licking his girlfriend.
It didn’t take long for MacKenzie to come. She cried out and arched her back. Her hands clutched her breasts as she did.
The whole time, her mom watched with her hands between her thighs. She hadn’t turned her vibrator on, though.
Finn straightened up. He knee-walked forward until his hard cock brushed MacKenzie’s pussy. Then he looked expectantly at her mom.
Ms. O’Connell gave them a saucy smile and then flipped the switch on her vibrator. She held it for a moment before lowering it just above her pussy. With her legs spread slightly, Finn could now see everything. She’d trimmed her pubes into a triangle that pointed at her full lips below.
“Keep going,” she urged.
Finn chuckled. They hadn’t actually started, but now was not the time to get pedantic. Instead, he slid a finger down to MacKenzie’s pussy and started rubbing her. She spread her thighs a bit more and lowered her shoulders. He spread her pussy open and lined up his cock. She gasped as he slowly pushed in.
Ms. O’Connell sucked in her breath. Her eyes were wide as she watched Finn begin to stroke in and out. At the same time, she was now running the tip of the vibrator in small circles around her clit.
Finn did his best to ignore the pleasure washing through his dick. His girlfriend’s hot pussy seemed to clench with every thrust. He went slowly just to avoid coming too soon. He wanted Ms. O’Connell to come first.
Her breathing grew ragged as she moved the vibrator tip around. The whole time, her eyes remained locked on Finn’s cock and MacKenzie’s pussy. Her nostrils flared when he thrust in deep.
MacKenzie moaned.
Her mom gasped in reply.
Finn sped up, just a little. MacKenzie groaned and clutched the couch. Ms. O’Connell continued to gasp hard. Slowly, almost agonizingly, the three climbed toward their peaks.
MacKenzie came first, with a loud moan and an arched back Her mom’s eyes shifted to her daughter’s face, and then dropped to her breasts and hard nipples. Then Ms. O’Connell shuddered and came herself. Watching her put Finn over the edge. His legs trembled and he gasped as he exploded.
All three slowly caught their breath and recovered. Finn stayed inside MacKenzie, even as he began to soften. When he caught Ms. O’Connell’s attention, he smiled at her.
“What would you like to see next?” he asked.
“How soon until you can go again?”
He shrugged. “Twenty minutes, maybe.”
“He recovers faster when I suck him,” MacKenzie added.
“Well, then...” Her mom smirked.
With a small laugh, Finn and MacKenzie switched places. Once he’d settled on the couch with her crouched between his thighs, they both looked at Ms. O’Connell. She smiled and turned her vibrator back on.
MacKenzie’s blowjob wasn’t her best. She kept watching her mom instead of focusing on what she was doing. She didn’t scrape him with her teeth, thankfully, but while he was slowly getting hard, that was mostly from watching Ms. O’Connell’s breasts rise and fall as she panted in pleasure.
“Any requests?” Finn quietly asked.
“Mac on top.”
“I’m not quite hard enough yet.”
Ms. O’Connell nodded. She thought for a moment.
“Hey, sweetie,” she said to her daughter, “try lightly cupping his balls while you suck on the crown.”
MacKenzie’s eyes widened, but then she did just that.
