Finn sat, blank-faced, as he tried to think of what to say. MacKenzie looked equally shocked and confused as her mom stood there, one hand on her hip, looking at them. After a moment, she moved around the couch so Finn and MacKenzie didn’t have to swivel their heads.
“You want someone else to join you in bed?” Ms. O’Connell asked. “That’s it, isn’t it?”
“Uhh...,” Finn stammered. But now his brain was starting to unfreeze.
“Megan’s cute.” Ms. O’Connell looked pointedly at her daughter. “And a great kisser from what I could see.”
“Oh, God!” MacKenzie buried her face in Finn’s shoulder.
“But you need to be careful,” Ms. O’Connell concluded.
“Careful?” Finn asked.
“What if Mac likes Megan more? Or Eli?”
“Huh?” Finn rubbed Mackenzie’s back, but now he was thoroughly confused.
“I get it,” Ms. O’Connell said. “It’s fun. And I know you two love each other, but you are so young.”
“Yeah...”
“You could really get burned.”
MacKenzie lifted her head and faced her mother. “Is this about Dad?”
Ms. O’Connell rocked back and blinked.
“Or should I say, Dad and Greg?”
Ms. O’Connell sighed and her shoulders sagged. She looked around until she spotted the upholstered chair off to the side and then sank into it.
“Dad and Greg?” Finn asked. “Your dad’s husband?”
“Yeah. Dad left Mom for Greg.”
Finn nodded. He kind of remembered that, but they lived out of state and he’d only met MacKenzie’s dad a dozen or so times. Everyone had been cordial, so he hadn’t thought much of it.
“It wasn’t that simple,” Ms. O’Connell said.
It was Mackenzie’s time to look confused. “That’s what you said.”
“Well, you were young. Too young.”
“For what?”
“The truth.”
MacKenzie shifted until she was sitting straight up. “So what’s the truth?”
Ms. O’Connell took a deep breath. She sat still, clearly thinking of what to say.
“What’s the truth, Mom?”
Ms. O’Connell took another deep breath.
“Mom?” MacKenzie pressed.
Ms. O’Connell sighed. She looked away, avoiding her daughter’s gaze.
“Your father didn’t leave me,” she said. “It was mutual.”
“Mutual?” MacKenzie furrowed her brow. “But you said—”
“I said your dad wanted to be with Greg more than he wanted to be with me.”
“Okay...”
“And I wanted to be with Caroline more than I wanted to be with him.”
Stunned silence filled the room for a dozen of heartbeats, before MacKenzie almost shot to her feet.
“Auntie Caroline?”
“She’s not really her aunt,” Ms. O’Connell quickly said to Finn.
“But ... you and Auntie Caroline were ... lovers?”
“For several years.”
“But you’re not now.”
Ms. O’Connell shook her head.
“What happened?” Finn asked.
“She met the man who became her second husband,” Ms. O’Connell said.
“Second?” Finn asked. “Oh, wait—”
“Mmm hmm. Greg was her first.”
“Wow,” Finn said quietly.
Ms. O’Connell looked plaintively at MacKenzie. “I know you want to be with Megan, but...” She sighed. “Don’t screw it up with Finn.”
“I won’t!”
“You, too,” Ms. O’Connell said to Finn.
“Not a chance.” He emphasized his words by squeezing MacKenzie’s shoulder.
“Good. Now...” Ms. O’Connell pursed her lips in amusement. “I came out here to ask you two to help with supper.”
“Happy to,” Finn quickly said.
“Mmm hmm.” MacKenzie agreed
Finn stood, wondering just how the dinner conversation was going to go.
They had rigatoni in a bolognese sauce with Caesar salad for dinner. Ms. O’Connell opened a bottle of Chianti and actually got out three glasses. Finn raised an eyebrow but didn’t say anything. She’d long established that she didn’t care about the eighteen-year-olds drinking as long as they didn’t drive. Besides, if it helped her relax, more to it.
For he could sense the tension. As they cooked, MacKenzie bit her lip multiple times, holding back unspoken questions. Her eyes constantly darted to her mother, who wasn’t oblivious. Ms. O’Connell’s shoulders tensed when she caught her daughter’s stares. Her smile grew forced. By the time they sat down to eat, Finn wondered who would speak first.
He got his answer when Ms. O’Connell paused after her first sip of wine.
“I suppose you want to know more,” she asked.
“Yeah!” MacKenzie snapped.
Her mom pulled back in surprise.
“I mean, why have I never heard this before?”
“You were too young,” Ms. O’Connell snapped back.
It was MacKenzie’s time to rear back. Finn jumped in.
“Yeah,” he said, “but she’s not now. So ... what happened?”
Ms. O’Connell sighed. “What do you think happened?”
“You swapped partners, obviously. But why?”
She shrugged. “Because ... Jerry decided he loved Greg more, and I was in love with Caroline.”
“So you’re gay,” MacKenzie said.
Ms. O’Connell paused but then forced a head shake.
“No,” she said. “I’m bi. Just like you.”
MacKenzie gasped.
“I saw you kissing Megan.”
MacKenzie shrank in her seat.
“Bi, gay, who cares?” Finn interjected. “You left your husband for your friend.”
“It’s more he left me,” Ms. O’Connell said.
“Huh?”
“Greg insisted he choose. Jerry chose Greg.”
“But how did you get to that point?” MacKenzie asked warily.
“How do you think?”
MacKenzie blanched.
“You were ... doing it,” Finn said. “Together. Group sex.”
“Got it in one.” Ms. O’Connell raised her wine glass and took a big sip.
“Wow,” MacKenzie said softly. “Wow.” Then she lifted her own glass.
Finn waited until both women had finished their drinks.
“But you didn’t keep having group sex,” he said.
“No. Greg ... isn’t cut out for sharing.”
“No,” MacKenzie agreed. “At least from what I know of him.”
“Yeah ... and your father fell for him, and then chose him.”
“That won’t happen to Mac and me,” he said. “Falling for others.”
MacKenzie nodded vigorously.
Ms. O’Connell tilted her head and regarded him. “How do you know?”
“I just do. We do.”
“That’s what Mac’s father and I thought, too.”
“Well...” Finn trailed off as he realized he had no idea what to say.
“It won’t happen to us,” MacKenzie said. “It won’t!”
Her mom shrugged. “How can you really know?”
MacKenzie and Finn exchanged a look. How could they?
“Think about it,” Ms. O’Connell said. “In the meantime, the food’s getting cold.”
Reluctantly, Finn picked up his fork. He knew there was more to discuss, but he didn’t know what words to use.
