Put on your big girl dick and fuck them like you mean it.

You remember the surge of power you felt pounding your slutty sister until she squirted all over you. You remember the rush you got when you pinned down your controlling crush's tongue with your own. You realize that just because it's easier to be passive and you get a twisted thrill out of being a subby slut, doesn't mean you can't be assertive and dominant when you want to.

You dig through the toy chest and find something suitably intimidating looking: a foot long truncheon with rubber spikes. It comes with a remote that has settings from low hum to liquefy. You strap it on over your pantied prick, so every slam will squeeze your shaft. You pull out a studded paddle to match and manage to keep your voice from cracking as you call out, "Just remember, sluts, you asked for this."

Dropping her sweet taffy tough act at the first opportunity, Emma is crawling on hands and knees, looking so lewd with her red rubber body suit hugging her curves and her breasts and doggy dildo swaying freely as she makes her way over to nuzzle your leg. "Ooh lookie, Missy, we've got a new boss bitch! I wonder if she's all baAAAAAIEEE!" You answer her question with a solid SMACK to her raised rubberized rump. She squeals more in surprise than pain as the paddle makes her ample ass quake deliciously. You look at Cindi and point to the ground next to your feet.

The cold eyes cheerleader walks slowly, nose turned up in playful snobbish superiority as she closes the distance. She wears her nudity with pride, her stunning figure and strap on showing strength. Clearly, she isn't going to make this easy on you just because you are all dating now, and you wouldn't have it any other way. "Hmm, not a bad swing, but you should snap your wrist at the moment of impact, it adds a lot more tor-EEP!"

You yank Cindi back with you as you fall into the leather throne at the middle of the room. She is in midstep and off balance allowing you to pull the taller, more athletic amazon off her feet and onto your lap. She squirms on your lap, causing your strap on to crush against your cock, now hard again and ready for Round 2. You grope her tight round ass and ask, "So do you sluts have a safeword?"

Emma is entranced by the sight of her Mistress turned girlfriend bent over your knee. She is reaching behind her puppy prick to cram four fingers into her wet pussy, moaning, "It's Keebler MOAN elves EEE!" She squeals as if she was the one SPANKed by the punishing paddle and not Cindi. The princess doesn't make a sound, but you can see a trickle of desire dribbling from between her thighs practically begging for more.

TWACK SMACK CRACK

You make sure to snap your wrist as you strike, and sure enough, it does add torque. Tough as ever, Cindi doesn't make a peep, but her face is almost as red as her battered buttocks and her lower lips are drooling all over you. "Emma, be a good slut and take off Cindi's strap on. She won't be needing it this morning." Your sister hesitates as if looking for permission from the rosy cheeked cheerslut on your lap, but scurries to attention when you bark, "Now!"

SMACK THWACK KARAAK SPAAAANK CRAAACK

You alternate between cheeks landing blow after blow as Cindi looks up you with a mix of anguish and arousal. She still doesn't cry out, and that's just fine with you. You want to hurt her in the sweetest way possible, not humiliate her. Setting down the paddle, you caress her cheeks, massaging out the stinging heat and petting her pretty head. "That's my strong slut. You can cry out know if you want to." You slide your hand between her cheeks and cup her wet cunt. Your fingers slide between her folds and despite herself, she raises her rump to hump your hand, making whispery whimpers and stifled sobs of pleasure.

You give a solid SMACK to her pussy with your palm and she starts shaking all over. You firmly, but not roughly lift her head by the hair and look down at her lovingly. "You are so sexy when you fight it, and so sexy when you surrender. Now Emma and I are going to double team you and see how many screams we can **** out of you. You can fight it or you can give in, and either way I'll be proud of my little..." you squeeze her ass hard, "slut..." you plunge four fingers into her pussy, feeling out the spots that make her squeeze down hardest, "****!"

"FuckfuckfuckFUCKINGfuckmeeeEEEEEEE!" Cindi loses control as she explodes on your lap. Emma, never one to waste a good drenching, is below her in seconds, mouth open and tongue darting to catch her delicious droplets like snowflakes. You let her thrash and flail and keep fingering her until your sister's flushed face is absolutely drenched. You pull your fingers free and let Cindi fall limp on your lap as you suck her sweet spray from your hand. Feeling generous, you place your fingertips on Cindi's beestung lips. At first she tries to maintain what little decorum she can muster, tentatively tasting her cum with dainty licks, but she soon gives way to greedy snorting sucks until your hand is clean and wetter than ever.

"Good girl." You say gently, with genuine affection. "Now, are you tough enough to get double teamed by two subby sluts?"
