A teen redhead

With Nina gone, and Claire preoccupied with teasing Tommy to ever greater sexual frustration, you turn back to Rachel for some attention.

"Come here, Rach,” you snap, clicking your fingers at her and beckoning her over as you would a dumb animal.

She keeps her head lowered to the floor in defeat, but does as she's told and crawls over to you, ass gaping and leaving a trail of cum droplets across the floor.

"I figure your ass deserves a rest after such an impressive anal session, Rach," you say, reaching over and giving her sore, rosy ass cheeks a sharp slap.

Rachel flinches quietly, then kneels in front of you. She looks down and doesn't bother arguing, but you can see a frown on her messy face. After the long string of abuses you've inflicted on her since you first throat fucked her on the family couch, you doubt she expects anything from her perverted brother except more degradation and sexual ****. Well, she's right about that!

"Your throat, however, has been empty far too long." You pat her on the head demeaningly. "Open up!"

She does as she's told without hesitation or question (not that she has a choice in the matter at this point!) You find it pleasing that your sibling has finally learned her proper place in the household. Now that she's physically incapable of fighting back, she's a lot easier to manage. However, it does mean you'll have to come up with fresh new ideas if you want to keep her entertaining. You look down at her once cute face - now covered in gag slime, cum and sweat - her lips wide open and inviting, a little pink tongue visible inside the gaping fuckhole in her face. You take a minute to imagine her skinny body in a variety of twisted positions before coming to a decision and grinning.

"Okay Rach, I know what we can do! Start off by sticking your fingers down your throat, get them all wet for me," you order. "I'm going to need some lube..."

Claire, meanwhile, is busy stroking Tommy's engorged phallus. She jackhammers her clenched hand up and down his fat shaft. She alternates between stimulating him and cutting off his pleasure with a firm squeeze to the base of his cock when he seems ready to burst. In doing so, she manages to both excite him into a state of sexual frenzy, whilst delaying his sexual aggression with dirty talk and promises of epic throat fucks.

"You want to cum, hmm?" Claire teases. "You want to shove this thick meaty shaft in some poor, helpless girl's mouth - **** her, dominate her, make her drool and slobber all over you while you **** her throat hard and deep? Do you?"

Tommy's dick lurches, and Claire stops jerking him off to let him recover. "Just a little longer, Tommy dear," she says. "Any minute now, Nina's gonna walk through that door with a fresh new toy for you to destroy!"

"Fuck that, I need to cum, now!" Tommy cries, reaching out and grabbing your step mom's head. "Get over-"

Just in the nick of time, you hear Rachel's bedroom door open, and turn to see Nina holding hands with a stranger - a teenage redhead. You and Tommy both take stock of the new girl.

The gentle mounds of her top suggests she has small breasts, not completely flat chested but nowhere near as busty as Nina. She's very slim, with long, pale legs and a beautiful, heavily freckled face. She's not wearing any makeup just yet, but even so her plump cock sucking lips are noticeable. Nina chose well.

The redhead looks around, eyes wide and innocent. Her gaze wanders around the array of naked female flesh, the fluid-splattered bed and carpet, and especially the two enormous, throbbing erections now pointed in her direction. She appears more curious than afraid, but definitely shy. You wonder just how innocent she really is.

"I found her waiting for her sister outside the school down the road. I hope she's good enough for you?" Nina asks.

"Oh yes, darling, she'll do just fine," Claire purrs, teasing Tommy's shaft with one hand and beckoning the new girl over with the other.

Nina turns to you. "David, I'm worried. The world-leaking has already started. There are already a couple of-"

"Nina! Come help me with the new girl!" Claire interrupts, ordering the BJU rep to join her on the cum saturated sheets of your little sister's bed. Nina looks to you and raises an eyebrow. You nod your head towards Claire in confirmation, eager for the show to begin. Whatever she was on about probably isn't worth worrying about, anyway.

"How old are you, sweetie?" Claire asks, licking her lips and rubbing her spare hand in rapid circles over her clit.

"Eigh... eighteen", the redhead says quietly.

"Perfect", Claire says, slipping two fingers into her wet pussy and moaning. "What should we call you?"

"M.. my name's Zoe", the new girl replies.

Nina slinks behind the redhead and runs her palms seductively up her waist and back to rest on her shoulders. She caresses the new girl gently as Claire talks, subtly sliding her top down over her shoulders to reveal more pale, freckled skin. The redhead can't look away from Claire's wet pussy, and starts to blush.

"How about it, Zoe?" Claire grins. "Would you be willing to come help us out here? My poor friend here is in dire need of another orgasm, but his last partner is all used up, and we need someone a little... fresher, to spice things up. Think you can handle the job?"

"Um... I dunno. I sup... suppose so?" Zoe stutters, blushing deeper.

Nina looks proud of herself. Claire grins and nods in approval. She rubs Tommy's shaft slightly faster, but avoids the bulbous head of his cock, driving him to the edge of frustration. Zoe gasps and alternates her gaze between your step mom's leaking pussy and Tommy's twitching cock. Her eyes are wide, and her blush has spread from freckled cheeks to slender neck. Yu begin to suspect she's never seen a cock in the flesh before. You stifle a laugh. If Tommy is indeed to be her first partner, this sweet and innocent teen has no idea of the kind of ordeal she's just agreed to.

Tommy, in turn, is staring at Zoe with unabashed lust and need. He licks his lips, and you have no doubt that he's imagining ravaging her fresh, tight young body until it's just as messy and broken as poor Rachel's.

Thoughts of Rachel bring your attention back to your little sister, still following your last order and gagging herself on her fingers. You pull her hand out from her mouth, strands of thick gooey saliva pooling and dangling from her cupped palms. You figure they're wet enough for what you have in mind, and tell her what to do next...
