Phoebe beckons for Abbie to join her

Phoebe glanced over her shoulder again, this time with unmistakable intent. She locked eyes with Abbie and winked -- a deliberate, unhurried gesture that sent a jolt through Abbie's body. Turning back to Megan, Phoebe continued working her fingers in and out of her lover's pussy, her movements becoming more rhythmic and forceful.

Jake, meanwhile, had found his rhythm behind Abbie. His thrusts were becoming deeper, more insistent. Abbie felt the familiar pressure building inside her as Jake's hands gripped her hips tighter, pulling her back against him with each forward movement. The sound of skin against skin was barely audible over the kitchen noise beyond the plastic flaps, but Abbie could feel it -- the slight slap of his body against her ass, the wetness between her legs making each thrust smoother than the last.

It was a strangely powerful feeling, being the only one who knew the full picture. Jake was fucking her from behind, his breathing hot against her neck, completely unaware of what was happening around the corner. Megan was bent over, eyes closed in ecstasy, oblivious to being watched as Phoebe's fingers worked inside her. And Phoebe -- well, Phoebe knew about Abbie, but not about Jake.

The asymmetry of knowledge made Abbie feel both **** and powerful. Her body was the nexus point between two separate sexual encounters, and only she could see how they connected.

Phoebe slid her fingers out of Megan with a deliberate slowness that made Megan whimper. With her glistening fingers extended, Phoebe reached toward Abbie, crooked her index finger in a come-hither motion, and mouthed the words "Join us."

Abbie's heart hammered against her ribs. The invitation was unmistakable, and every cell in her body wanted to say yes. But what about Jake? She couldn't just leave him mid-thrust. And would Megan be okay with strangers joining their private moment? Phoebe clearly was, but Megan hadn't even seen them yet.

Jake must have sensed her hesitation because he slowed his movements, his hands questioning on her hips. "What is it?" he whispered, his breath hot against her ear.

Abbie turned her head slightly, just enough to whisper back without losing sight of Phoebe. "She wants us to join them."

Jake's cock twitched inside her. "Both of us?"

"I think so. I mean, she doesn't know you're here, but ..."

Abbie trailed off as Phoebe made the beckoning gesture again, more insistent this time. It may not have been a verbal question, but Abbie understood the request and was excited to take part. At the same time, she wasn't sure what to do about Jake. She knew that Megan and Phoebe were lovers, but would they object to a man joining them? For that matter, would Megan appreciate Phoebe inviting total strangers into their episode at all?

Abbie figured that it would all work itself out one way or another, and as she did with everything else, she agreed and went on the next adventure.
