Finn eased out of MacKenzies’s pussy and slowly sank to the floor. She twisted around and sat next to him, her head on her shoulder.
“That...,” she said, still panting, “ ... that was amazing.”
He chuckled. “You don’t know that half of it.”
“Huh?”
“Your mom watched.”
“She did?” Mac’s voice trembled as she stiffened.
“Yeah ... and ... she was touching herself.”
Mac gasped.
“Mmm hmm.”
“Wow. Just ... wow.”
He chuckled. “Uh-huh.”
“So..., she asked, “what now?”
“No idea.”
The both sat for a bit, before MacKenzie grabbed her discarded panties.
“Gotta pee.” She gave him a quick kiss on the cheek before she hurried off.
Finn cleaned up the family room and quietly headed down to MacKenzie’s room. Ms. O’Connell’s door was as closed and as dark as it had been before. If he hadn’t seen her, he would’ve sworn she’d just slept through everything. Inside Mac’s room, he stretched out naked on her bed and waited.
When MacKenzie arrived, she still wore her lingerie, except for her panties. She grinned when she saw his half-stiff cock. Then she removed her bra and reached for her garter straps.
“Leave them,” he said.
She immediately stopped and looked at him questioningly.
“You look really hot, and...” He smirked and gave his cock a few strokes.
She grinned and climbed on the bed.
“You on top for Round Two?”
She returned his smirk. “If that’s what you want.”
Her hand joined his and, as soon as he was hard, she straddled him and slid him inside her.
She sighed happily.
He ran his hands along the tops of her thighs, from her stockings to her hips and waist. She slowly ground against him. He met her with small thrusts that made her sigh. Then MacKenzie started caressing her breasts as they slowly screwed.
“So...,” MacKenzie said. “Mom was...”
“Watching. And touching herself.”
“Wow.”
“Yeah. You’re not freaked out?”
“A little,” MacKenzie smirked. “It’s my mom.”
“Yeah...” He sensed MacKenzie’s thoughts and decided to put them into words. “But it’s kinda hot.”
MacKenzie nodded.
“And since it’s your mom, it’s kinda kinky.”
MacKenzie chuckled in agreement.
“Really kinky.” He smirked.
Her eyes smoldered, so he pulled her down for a kiss. Conversation died as they started screwing each other in earnest.
MacKenzie came first—more quietly than she normally did, mostly gasps and small moans as she quivered. When she finished, they rolled over to missionary and Finn pounded her hard and fast while she rubbed her stockinged feet down the back of his legs. It took him only a couple of minutes before he couldn’t hold back and exploded in pleasure as well.
Finn awoke way too early with a need to pee. Well, it wasn’t that early. The sun peeked around the window’s curtains. MacKenzie was curled into his side, so he carefully extracted himself without waking her. He grabbed the silk robe that MacKenzie had given him for his birthday and carefully closed the door behind him.
When he emerged from the bathroom, he smelled coffee. The kitchen light was on, so he padded down the hall.
Ms. O’Connell sat at the kitchen table, her hands wrapped around a steaming mug. She wore PJs and a robe and gave him a sleepy smile.
“Good morning,” Finn said.
“Morning.”
He poured a cup and sank into the seat across from her.
“How was Prom?” she asked.
“Okay.” He shrugged. “We had fun.”
“Mmm. Just okay?”
“The dance was just okay.” He smirked. “Later...? That was more than okay.”
She chuckled.
“It wasn’t quite what I expected ... but it was really good.”
At that, she blushed and averted her eyes.
“It’s okay,” he said. “It was just a surprise.”
She didn’t look his way, so he sipped his coffee quietly and waited. Eventually, she took a deep breath.
“Sorry,” she said without looking his way.
“It’s okay,” he repeated. “Mac didn’t freak out when I told her, and I ... I kind of liked it.”
Ms. O’Connell snorted. Then she backed up and stood.
“I need to go. I need to ... uh ... I need to take a shower.”
Then she quickly left the room.
Finn found MacKenzie slowly waking up when he returned to the bedroom. She rolled over and gave him a sleepy smile.
“You were gone a while.”
“Coffee with your mom.”
“Mmm?”
“Yeah. She’s in the shower now.”
MacKenzie furrowed her brow but slowly nodded.
Finn slid under the covers next to her. “I didn’t expect you to be awake.”
“Megan texted.” MacKenzie held her phone up.
“Oh? Why?”
MacKenzie handed him the phone. He punched the code to unlock it and then laughed. He scrolled up through the dozen messages. And chuckled again.
“Good for her.” He corrected himself. “Them.”
“She couldn’t wait to tell us.”
He nodded agreement and skimmed the messages again. “She’s waiting for Eli to wake up.”
“Yeah, I saw that.”
Another text came in and Finn barked with laughter.
“What?” MacKenzie asked.
“She’s really ready for him to wake up.” He smirked. Then he held up the phone. “May I?”
MacKenzie nodded.
He typed in a text. When he finished he set the phone down on MacKenzie’s nightstand and playfully leered at her.
“What’d you tell her?” MacKenzie asked.
“To wake him up with a blowjob. Because that’s what you were going to do.”
She grinned. “But you’re already awake.”
“Makes it even easier.”
She laughed and kissed him. He pushed the covers down, and she began kissing her way down his chest. When she reached his cock, he sighed.
It wasn’t hard to imagine Megan going down on Eli. And maybe some day she could join MacKenzie in going down on him?
He let his mind drift in the fantasy of getting a double blowjob while his girlfriend licked and sucked him. Then he happened to look at the door. He’d left it open.
He wondered if Ms. O’Connell was going to watch.
Ms. O’Connell was working in the yard when Finn and MacKenzie finally emerged, showered and dressed, from MacKenzie’s bedroom. Finn wasn’t sure what to say to her, or if he even should. It wouldn’t be hard to pretend nothing had happened.
It appeared to be what Ms. O’Connell was going to do. When they headed outside, she waved and asked how Mac was doing. Then she asked their plans. MacKenzie quickly volunteered to help in the yard, which is what they did until dinnertime and Finn headed home.
Ms. O’Connell did pretty much the same thing over the next couple of weeks. A couple of times, he left Mac’s bedroom door cracked open when they made love, but they never caught Ms. O’Connell watching.
