"Get closer"

"How much closer?" Tess asks.

"Much closer." you respond. You sense boundaries breaking down. You suppose for Greenie, it's one thing to be fucking someone across the room from her sister, another thing to be within touching distance.

That you even have to have this thought, is ridiculous.

And Greenie, as impulsive as she ever is, doesn't respond by giving you a whisper, but instead shouts. "GO!" and jumps off your cock, and runs across the room to where Katie is sitting.

You have **** but to jump up and run after her, your hard, wet cock wagging in front of you as you run. The whole scenario is laughable. And you hear Greenie laughing as she runs and jumps at her sister, lying down on top of her, on the chair across the room.

You laugh too, approaching milliseconds later, although everything feels like an eternity. And not. Time is going both quickly and slowly. It makes no sense.

But there is Greenie, now lying across her sister, her back on Katie's front, as if she's just another piece of furniture. Her legs up in the air. And it's not like you have to debate whether you're going to partake in this new turn of events. After all, it was sort of your idea.

You grab Tess's hips, open her thighs as much as needed. For the first time, you actually have a view of her wet, bald twat. Her pussy is small and tight, but her clit is thick and swollen. That you're seeing it at all feels filthy beyond comprehension, even after having fucked her, something about seeing her takes it to a new level. You push your body between her legs and insert your cock back inside of her. Which she greets with a goofy gasp.

And you start to thrust.

You're quite certain that Katie has a better view now, considering you're fucking Tess literally on top of her. And you watch as her eyes focus in on sight of your member penetrating her sister's slit. Her lips tremble. She takes a deep, labored breath.

She doesn't say anything. Even as you both ran over and jumped on her, she said nothing, which is unusual of her. She's not exactly shy. And now too, she just watches, intently.

She slips her hand out of the top of her jeans, and places her fingers on her sister's left hip, leaving wet marks where her index and middle fingers go. Maybe she's just steadying the three of you, now intertwixt together, but there's something about the physical contact that seems to increase the intensity of the situation, yet again.

You decide the right thing to do is to say something to her. After six years together, you're as close as a couple can be. You want to know how she's feeling. Because you're just not sure.

"Are you doing okay?" You ask her.

Her eyes just over to your face. And she nods and smiles a genuine smile "Yes. I just... I didn't think it would feel this way."

"What way is that?" It's ludicrous you trying to comfort her as your cock is planted deep in her sister.

"Like we're perverts now." Katie says, but not with a sense of regret, almost with a sense of simple bluntness. "Like we can't go back."

"Well..." You try to think of the right thing to say.

"Embrace it!" Greenie chimes in. You're not sure if it's the right thing to say, but you can't fault her for honesty.

You give Katie a shrug, as if to say 'maybe she's right.' Katie laughs, and you do too. "What do you think about the... embrace it... plan?" You ask. She'd better like it, because at the moment you've been fucking her sister with such intensity, you're running out of breath.

Katie starts to nod, first a little, then vigorously. You know what kind of look she gets on her face when she's having naughty thoughts. And she's definitely having them now.

She takes a deep breath. "I think if we're going to embrace it, you might as well..."
