Watch them make out.

"Well" you say,barely able to contain your glee "Who am I to turn down an offer like that"
Katy places her left arm around Scarlett's waist and pulls her in hard towards her.
Scarlett acts surprised,maybe even nervous with her head bowed slightly as she bites her bottom lip into the corner of her mouth but her eyes are wide with anticipation and you realize she's just putting it on for you benefit.
Katy raises her right hand up and starts to stroke Scarlett's cheek and caress her face,this causes Scarlett to let out a slight moan.
"Mmmmmmm" she breathes "That feels soooo good"
A smile creeps across Katy's face "You like that huh?"
"Mmm-hum" Scarlett replies,her eyes shut tight "Your touch is so soft"
"Really?" Katy ask's,taking her hand from Scarlett's face and entwining into one of her pig-tails "Then maybe I should get a little rougher"
With that,she jerks Scarlett's head back violently and buries her face into her neck,covering it in passionate kisses,only stopping to bite it hard.
"Oh fuuuuuuuuck" Scarlett pants "Don't fucking stop"
As Katy continues to devour her skin Scarlett drops her left hand to Katy's leg and raises it up to her hip,in doing so Katy's tight black skirt rises up showing you the top of her stockings and her suspenders and the sweet patch of skin that lurks underneath.
She runs her hand up and down Katy's thigh,both of them breathing heavily now,lost in the moment.
"Play with my tits" Scarlett begs "Pleeeeeeease baby,play with my big.fucking.tits"
Katy places her left hand on the back of Scarlett's head,cradling it and places her right one onto Scarlett's left breast.
"Mmmmmmmm" she moans into Scarlett's neck "they really are big.fucking.tits"
"They're as big as yours" Scarlett giggles,lowering Katy's leg to the floor.
Katy pulls her head away from Scarlett's neck.
"Really? " she say's in mock indignation "You think your tits are as big as mine?"
"Well" Scarlett says pushing her chest out towards Katy "What do you think?"
Katy follows suit so they are chest to chest,wraps her arms around Scarlett's waist and pulls her in tight,squeezing so much pressure into their outfits you wonder how the material can take the strain.
"Oh God" Scarlett moans,grinding her tits against Katy's "I am so fucking hot for you right now"
She parts her legs ever so slightly and Katy slides her slightly bent right knee between them before opening her own so Scarlett can return the favor.
As Katy's hands start to kneed and grope Scarlett's ass through her short skirt,Scarlet begins to grind her pussy against Katy's leg.
Katy,taking her cue from Scarlett,does the same,foreheads together,staring deep into each others eyes.
"Fuck!!" Katy pants,rubbing her clit against Scarlett's white knee high socks "You make me feel like such a dirty little slut"
"You are" groans Scarlett gazing into Katy's eyes "You're a dirty little slut and I'm a cheap.fucking.whore"
You watch as they both thrust their hips back and forth in unison,faster and faster now.
You feel that your cock's about to burst out of you jeans.
"OH SHIT!!!" Katy cries throwing her head back "I'M GONNA CUM!!! YOU READY BITCH!!"
"FUCK YES!!!" screams Scarlett "GOD I NEED TO CUM SO.HARD!!!"
They both turn to you,their eyes pleading with you to let them cum.
