She's not shying away, is she?

Instead of backing off, you pull her closer pressing you cock against her deliberately.

She breaks the kiss, barely.
Your breath mingles, as you stare deep into each other's eyes.
She is smirking mischieviously.
That's the signal.
Less gently than you wold like to, you drag her towards the couch, the one opposed to where Tom dragged Nicole.
She seems amused, though.

You play the game and push her down, and in the quickest way you know of, you get rid of your pants and shirt.
Meanwhile, with the corner of your eye, you notice that Sarah, naked save for her panties, has straddled Matt, and is giving him the ride of his life.

For a split-second, you can't help your mind going to Nicole, wondering what's happening back there with Tom.
They are most likely engaged in a similar activity, you can hear their grunts and moans, but they are behind you, out of sight, and you don't want to look away from Miranda, not even for a split second.

She is waiting, but not idly.
Her spread open legs invite you, while she pulls of her top.

Her black lacy bra squeezes marvelously her breasts.
You don't let her the time to even unclasp it and pin her down.

You kiss her again and again.
The temptation to penetrate her right away is strong, your cock is ready, barely a few inches away from her sex
It would take no effort really to plunge into her right away, just like that, but first you want to please her.
You want to mark the difference with that asshole.

She simirks coyly, pleased, as you trail down bewteen her breasts kissing her ribs, her navel.
Her skin so sliky, warm.
Again her scent makes you dizzy, as you dive between her tights.
She's wetter the before.

A lot more wet.
You try to push away the though that it's not entirely because of you, but you cannot avoid noticing with surprise how her asshole is still gaping.

No shit, Sherlock, she has been just stuffed like a turkey on Thanksgiving by that turd over there! What you were thinking?

With patience, you start nibbling her swollen lips prodding her slit with you middle finger.
It blooms eager under your touch, her moan getting shameless.
After all, is there any point at all in still holding back, seeing how everyone in the room is also having sex right now?
You tease her clit, drawing slow circles with your thumb.
Then start to suck it, a little too keenly maybe.
She twitches, her calves snapping around your back.
As you slide your index finger inside, her juices beging to soak your hand.

She looks down on you, frowning and biting her lips, while caressing her breasts through her bra.
It's hindering her now, but she managed to pull down the cups, exposing her nipples, succulent cherries that she keeps piching and pulling.
You easily manage to slide a second finger inside her, she barely notices.
As you begin to rub the inner wall of her moist self, slow at first, she feels the need to muzzle herself with the back of her hand, afraid of getting too vocal.
She is overflowing.

"Owww, fuck, John! Right there, d-don't stop pleeease! I need it, fuuuck!" She cries,
arching her back and tightening the hold of her her legs around you, as your hand works fervishly her slit.

Then you suddenly rember about Sarah's words.

If you guys wanted to make her really scream...

Hesitantly, you start teasing asshole with your pinkie, prodding it gently.

It seems tightly closed at first, but as you brush its wrinkled skin, you sink in effortlessly, causing Miranda's body to twitch violently,

"Oh God ... my God, ohmyGod,ohmyGodyes, yes, yesss! Right theeere! Fuck meee!"

You giggle as start squirting quietly on your hand, jabbering uncoherent shreds of sentences.

"Oh God, good God, oh my ... oh fuck ... fuck ... me... ohmyGodfuckme, fuck my ass, please ... don't stop, please, don't ..."

Sarah was right.
Sliding back and forth with ease up to three fingers now, your pinkie literally sucked in by the spasming muscles her cutle little back door, you drive her to a shattering orgasm and beyond.

You let her rest for bit with her eyes closed, her breast irregularly heaving, even if you feel more than ready for the main course.
This pause offers you the chance to look around.
