Jenny stared at Finn for what seemed like a full minute, though it couldn’t’ve been that long. Her shoulders and face were tense. Her breath had caught. Then she blinked. Twice.
“Pussy juice?”
“Mmm hmm. You know, um ... you know that’s what she’s interested in.”
“Yeah. With Megan.”
He shrugged. “But Megan’s not here.”
Jenny let out a breath. “Yeah.” Then she nodded. “Yeah. Megan’s not here.”
“Nope.”
“Well, then.” Jenny actually smiled. She took another breath. “Yeah.” Then she looked down at his cock and her eyebrows rose. “You’re hard again.”
“Well ... yeah. I’ve only come once.”
She chuckled. “First of three, right?”
“If we can manage it.” He smiled wryly.
“With someone as sexy as Mac?” Jenny scoffed.
“And you. Don’t forget yourself.”
“Yeah. But Mac’s the one you’re going to screw.”
He pursed his lips but decided not to say anything. She wasn’t ready for him to suggest she be the one. At least not yet. Instead, he asked, “Are you going to watch?”
“I might.”
“Anything you’d want to see?”
“Mmm ... let me think about it.”
He nodded and they sat quietly for a moment until they heard the toilet flush. A moment later, MacKenzie returned.
She’d taken the time to wash her face and pull her hair back. She still glowed and wore a “well-fucked” smile. She looked from Finn to her mom and then her eyes flicked down to his erection.
“So, what’s next?” she asked.
“We were just discussing that,” Finn said with a grin. “Your mom might want to watch.”
“Oh?” MacKenzie looked at Jenny expectantly.
“How about reverse cowgirl?”
“On the couch?” MacKenzie asked. “With you in a chair.”
“Mmm hmm.”
Finn smirked. That would give Jenny the best view of his cock sliding in and out of MacKenzie’s pussy. She never said it, but they all knew what she liked.
Round two went much like the times they’d done it before. Jenny got her vibrator and sat in a chair facing the couch. Finn couldn’t see around Mackenzie to know exactly what Jenny was doing, but from the gasps and moans and loud buzz, it was pretty obvious. Meanwhile, his girlfriend slowly rode him while he held her hips.
Jenny came first. She cried out and then the buzzing stopped. Then MacKenzie sped up and shifted her angle. She quickly achieved her own release. After she trembled and gasped for breath, she sagged forward and almost slid off Finn’s cock. He cupped her ass and helped her lift off him instead.
As MacKenzie collapsed onto the couch next to him, he finally got a good look at her mom. Jenny lay back lazily on the chair, almost tipping it off its feet. Her legs were spread, giving him a perfect view of her open pussy. She smiled before her eyes dropped to his cock.
“You haven’t come,” she said.
“Nope.”
“What would you like?”
“Maybe a blowjob?”
“Mac?” Jenny asked.
MacKenzie laughed. “I’m kinda tired. You do it.”
“He’s your boyfriend.”
“Who’s gone down on you twice.”
Jenny pursed her lips.
“Besides,” MacKenzie said as she shifted around and sat up straighter. “I wanna watch that.”
Jenny gave her daughter a quick curious glance before returning her focus to Finn’s erection.
“You don’t have to,” Finn said to her.
“No, I don’t.” But then Jenny looked up at them and smiled. “But why not?”
Finn resisted cheering.
Jenny caught his expression and rolled her eyes. “You’re loving this.”
“What’s not to love?”
“Well ... prepare to have your mind blown.”
“I don’t think that’s what you’re blowing,” MacKenzie quipped.
Jenny chuckled, but she also moved until she knelt in front of Finn. He spread his thighs and she nestled close before looking at MacKenzie.
“Can you see?” Jenny asked.
“Mmm hmm.”
Jenny smiled. Then she wrapped one hand around Finn’s dick and gave him a few tugs. She gave him one more smile before she lowered her head.
Finn gasped. Her lips move so slowly over the crown of his dick that it felt more like a gentle, wet massage than being sucked. He felt her tongue and then the pressure and then...
Ohmygod!
The sensations all blended together. He gasped as the first wave hit him and then moaned uncontrollably when she took another inch into her mouth.
She swept her hair back and looked up at him. Her eyes burned with lust and her nostrils flared.
Then she eased down another inch.
He stared at her—his mind blank. All that mattered was the amazing pleasure from her mouth.
Then she eased down yet another inch. She tightened her lips and he wanted to babble prayers to heaven. Her tongue, her lips, her—
Ohmygod! Ohmygod!
She had started to move.
She slid her mouth back up just as agonizingly slowly as she’d descended. Every nerve fired. Every muscle froze. He tried to speak, to moan, to groan, but no sounds came. He lacked the strength to do anything but tilt his head back in silent ecstasy.
He quivered as she bobbed her head up and down. She went a bit faster and didn’t take him as deep, but that’s all he could notice. It was just ... bliss!
And then he could feel the pressure building below. Slowly at first, but then racing up. He gave out a strangled cry—that was all he could manage—before he exploded.
The waves hit him so hard he almost passed out. His vision and hearing went. Then his sense of his limbs.
When he finally floated back down into his body, Jenny had already pulled back. She knelt with her hands on her thighs and looked extremely pleased with herself. Looking down at her took all the strength he had, so he just lay back and breathed deeply.
“Wow,” MacKenzie said.
Finn was too weak to nod.
“Mom?” MacKenzie asked.
“Yes?”
“You need to teach me how to do that.”
Finn chuckled. That’s what he needed. Two women capable of completely blowing his mind.
