Finn remained frozen as Ms. O’Connell looked him over.
“Twice?” She repeated.
“Well ... we were aiming for three.” He shot her a friendly smirk.
She laughed and rolled her eyes. “Oh, to be young!”
“Um ... yeah.” He pointed to MacKenzie’s room. “I gotta...”
“Uh-huh.” She chuckled. “Round three.”
“Uh...”
She waved him on. “Don’t stay up too late. I know it’s not a weeknight, but your parents will expect you home.”
He nodded. After an awkward moment, he turned and headed to MacKenzie’s room. At the last minute, he paused and looked back. He only caught a glimpse of Ms. O’Connell before she closed the door to her own bedroom.
MacKenzie sat in bed, clutching her panties to her pussy, where Finn’s come was undoubtedly seeping out. She gave him a nervous look.
“Everything okay?” she asked.
“Yeah...” Finn passed her the towel.
“I heard Mom.”
“Yeah.” He chuckled. “She heard us.”
MacKenzie’s eyes widened.
“No ... no, it’s okay. She wasn’t upset or anything.”
MacKenzie signed in relief. She took the towel and began cleaning up. “What’d she say?”
“She teased me about twice in one day.”
MacKenzie grinned. “We usually do three.”
“Ha! That’s what I said.”
MacKenzie’s eyebrows shot up. “Really?”
“Yeah.” He sat down next to her. “She didn’t mind.”
“You sure?”
“Yeah. You can talk to her if you want.”
MacKenzie shook her head.
“What do you want?”
“A shower.”
He nodded. “Together?”
MacKenzie furrowed her brow. “But Mom...”
“Doesn’t mind. C’mon. I’ll wash your back.” He stood and held out his hand.
MacKenzie hesitated for only a moment before taking it.
Mrs. O’Connell’s door was still closed when they emerged from MacKenzie’s bedroom. They paused and listened at it, but didn’t hear anything, so they continued onto the bathroom.
Finn adjusted the water temperature while MacKenzie brushed her hair. He climbed in first and then blocked the spray until she had joined him. They kissed, long and deep, before pivoting so they could both get wet.
Like so many times before, they didn’t talk as they washed. He soaped up her back, and then when she turned, her breasts. She grinned as he did so, but didn’t speak. Once he’d done her legs, he gave her a quick pat on the ass. She jumped but just rolled her eyes.
She washed her pussy herself, grinning at him the entire time. Then it was his turn.
MacKenzie kissed him, long and languorously, before he turned and she soaped his back. When she worked her way down, she just caressed his ass lightly. After she did his legs, she remained on her knees when he turned.
His semi-hard dick brushed her forehead.
She giggled, and he grinned in reply.
“You gonna suck it?” he teased.
“I don’t know ... do you want me to?”
“You know I do.”
She grinned and rose up on her knees until his cock was in front of her lips, never breaking eye contact as she did. Then she opened her mouth and stuck out her tongue.
He sucked in his breath with the first lick. When she began to suck, he gasped.
But she didn’t suck long. After only a minute or so, she pulled off and rose to her feet. He pulled her into his arms and they kissed.
“Tease,” he said.
“You know what I want,” she shot back.
He chuckled. “Horny girl.”
She nodded, and kissed him again, passionately.
“Okay,” he said when they pulled apart. “But on a bed.”
“But Mom...?”
“She won’t mind. Really.”
MacKenzie thought for a moment, and grinned. Then she wrapped one hand around his shaft.
“Good,” she said. “Because I want this.”
Finn quietly opened the bathroom door and peeked out into the hallway. Mrs. O’Connell’s door remained shut and the rest of the house was as dark as before. He gestured for MacKenzie to follow him and they stole down the hallway. When they reached Mrs. O’Connell’s door, they paused, listening.
Moans.
Finn’s eyebrows shot up.
The moans were followed by gasps and cries of pleasure.
MacKenzie looked at him, wide-eyed.
He gestured toward MacKenzie’s bedroom.
They hurried on, as quietly and as quickly as they could.
“Was she...?” MacKenzie gasped once they’d shut the door behind them.
“I think she was,” Finn replied.
MacKenzie giggled nervously. “I know it’s been a while for her. With a guy, that is.”
“Yeah. But ... now? Tonight?”
MacKenzie’s eyes went wide with the implication. “Do you think ... because of us...?”
He shrugged. “Maybe. Does that bother you?”
She shook her head. Then she smiled at him, broad and inviting.
He pulled her in for a kiss. A moment later, their towels hit the ground.
Round Three went more slowly and tenderly than the first two. Once he was inside her, they kissed and kissed as he slowly thrust. When he got tired, they rolled so that she was on top, but once again, the kissing was the point as much as being inside her.
Well, being inside her was pretty damned good.
She lay on his chest, kissing, as he slowly pushed in and out. When she got tired, she lay her head on his shoulder and just breathed deeply.
He could feel her heart beating. They rested until she finally turned and pulled up enough to look into his eyes.
“I wanna feel you come.”
He grinned and started thrusting harder. Having already come twice, it wasn’t going to be instantaneous, which MacKenzie knew.
MacKenzie shifted so her lips brushed his ear.
“Just think...,” she murmured, “ ... my mom was masturbating ... thinking of you...”
With a groan, Finn went over the edge. Mac grinned as she felt him empty himself into her.
MacKenzie, clad in her robe, walked Finn to the front door. Warm and tingly, they held hands until he opened it and turned to her for a kiss.
When they were done, he said. “Amazing night.”
She smiled.
“And amazing lingerie.” He waggled his eyebrows and grinned.
Her smile grew, then she turned thoughtful.
“Yeah...?” he asked.
“Maybe ... maybe we could have Eli and Megan over next weekend?” she asked. “And get in the hot tub?”
He chuckled. “She really got you going today, didn’t she?”
MacKenzie sighed and nodded.
“Okay.” He gave her a quick kiss. “We’ll invite them. But don’t be surprised if nothing happens.”
Finn leaned back against the brick wall and undid his lunch bag. The warm spring sun felt great as he waited for Eli to get settled in next to him. Eli brushed his mop of black hair back and grinned.
“So,” Finn said, “how about you and Megan come over Saturday and, you know, watch a movie or something? You could bring your suits and we could get in the hot tub.”
“Saturday?” Eli grunted. “Big Lakers game.”
“So watch it at Mac’s.”
“You wouldn’t mind?”
