Awkward silence hung in the air for several heartbeats. MacKenzie’s mouth had dropped open as she stared wide-eyed at her mother. Ms. O’Connell continued to hide her face. The tension grew thicker with each passing tick of the metaphorical clock.
Finn’s mouth was dry, but it was clear it was up to him.
“Well...,” he drawled, “I guess that means Mac and I get to be more romantic. Of course, if we get too syrupy sweet, you’ll have to let us know.” He mock leered at Mac. “Isn’t that right, my sweetums, buttercup, rose of a lady?”
“Rose of a lady?” MacKenzie laughed in disbelief.
“A rose by any other name would still smell as sweet,” he continued, adding a playful leer, “and I do love the smell of your petals.”
“Really?” Ms. O’Connell lowered her hands. She was smiling, even though her face remained red. “Smell of your petals?”
He smirked. “Well, ‘taste’ didn’t make a lot of sense.”
“You are incorrigible.”
He smiled and shrugged.
“And I...” Ms. O’Connell set her glass down and started to rise. “ ... have clearly had too much to drink.”
“It’s okay—” MacKenzie began.
“No.” Ms. O’Connell shook her head firmly. “I should get some water and some sleep. You kids ... do ... whatever it is you’re going to do.”
They fell silent as Ms. O’Connell made her way out of the tub. MacKenzie waited until she was inside to turn to Finn.
“She’s watched us?!”
“That’s what she said.”
“Oh my God!”
He shrugged. “So what?”
“What do you mean, so what?”
“She knows we’re doing it. She’s heard us. Seeing us isn’t much different.”
“She said watching. Not seeing.”
“Huh.”
“Yeah...”
He paused as that sunk in. MacKenzie waited quietly.
“Well...,” he finally said. “Does it bother you?”
“Umm...”
“I know it should...”
“Yeah...”
“But does it?” he asked. “Does it really?”
“It should...”
“But it doesn’t, does it?”
She slowly shook her head in agreement.
“So...,” he continued. “I don’t see why we should change anything we do. If she watches, she watches.”
“Yeah.”
“It’s not like we’d necessarily know anyway. We didn’t know until she said something.”
MacKenzie grinned. “True.”
“So...” He playfully leered at her. “How about we finish our drinks and go to your room? We know she won’t be watching tonight.”
MacKenzie laughed and quickly drained her glass.
They made love slowly on MacKenzie’s bed. They weren’t particularly loud, but neither made any attempt to be quiet, either. MacKenzie cried out when she came, and Finn added his own moan when he went over the edge himself.
Afterward, they cuddled. MacKenzie curled up into his side with her head on his shoulder.
“So...,” she asked after a bit, “when do you think she watched us?”
“Your mom?”
“Mmm hmm.”
“Not sure.” He paused and thought. “We always close the door to your bedroom.”
“And the bathroom.”
“Yeah.” He had a hard time imagining Ms. O’Connell peeking in windows, either. “And we’re careful in the family room.”
He smirked. “Except for when we lost your panties.”
“You think she watched us then?”
“No way. Not how she reacted.”
“Yeah...”
As he remembered back, something else clicked.
“Oh...,” he said, “I think I know.”
“What?”
“The second round. That day.”
“Yeah...?”
“I may not have closed the bedroom door all the way.”
“Huh?”
He sighed and rubbed her shoulder. “Yeah. When I went out to get the towel, she was in the hall, remember?”
“Ohhhh.”
“Yeah.”
They just held each other for a while. Finn wondered what MacKenzie was thinking. She was far calmer than he’d expected, but maybe she’d gotten used to the idea that her mom had watched them. She certainly wasn’t acting like she was disgusted. He started lightly rubbing her shoulder.
She responded by running her hand lightly up and down his chest. After a moment, he asked,
“What are you thinking?”
“Umm ... well...”
Instead of continuing her answer, she slid one hand down to his cock. He wasn’t hard, but that didn’t prevent her from gently stroking him. He slowly stiffened as she did.
“Round three?” he asked.
“Yes, please.”
Ms. O’Connell smiled broadly when she opened the door and saw Finn in his tux. “My, you look handsome!”
He grinned. “Thanks!”
He followed her into the family room and dropped his overnight bag by the couch. His eyes darted toward the hall where MacKenzie’s door was closed.
“She’s almost ready,” Ms. O’Connell reassured him.
He nodded and avoided clutching the corsage box in his hand. He didn’t want to crush it. Then the door opened and MacKenzie emerged.
His jaw dropped.
She wore a dark burgundy dress that really set off her skin tone. It had bare arms and deep cleavage and hugged her hips like a second skin. She’d pinned her hair up and her make-up was perfect. The dress stopped mid-calf revealing black hose and new high heels.
She looked like a goddess.
“You. Look. Amazing!”
Her smile lit up the room.
“Amazing,” he repeated.
Her eyes twinkled. “You look pretty good yourself.”
He presented her with the corsage. Afterward, they posed for photos and Ms. O’Connell agreed to send copies to his parents. As they headed to the door, she stopped them.
“Oh,” she said. “I’ll be asleep when you come home. So just let yourself in quietly.”
“Will do,” Finn said.
MacKenzie nodded in agreement.
She looked so beautiful, he couldn’t help it. He stole a kiss before they headed out the door.
The dance was fine. Not amazing. Not awful. But fine. Finn and MacKenzie danced some, talked with their friends some, and ate way too many of the canapés that the catering company made. They cheered when the Prom King and Queen were announced, but otherwise largely did their own thing.
They did spend some time hanging out with Eli and Megan, both of whom were nervous balls of energy. Eli kept joking about there not being any booze at the dance. Megan and MacKenzie had several private conversations that Finn couldn’t hear.
Then Eli and Megan cut out early, around nine o’clock. Megan was quivering with excitement as they said goodbye. Finn avoided chuckling and just gave her a friendly hug.
