Lana squirms on your lap as you thrust upward, pushing your rock hard cock deep into her tight pussy. She presses her back hard against your chest and moans as quietly as she can.You give her a moment to get used to your size before you begin to fuck her, bouncing her on your lap and driving your throbbing shaft deeper into her with each stroke. Her moans get louder and louder, and she whips her head to the side.

“Don’t,” she gasps. “N-not so hard…! We’ll wake my siblings!”

But you don’t slow down. Instead you start to fuck her harder, faster. Her eyes go wide as you slap a hand over her mouth, muffling her cries of embarrassment and passion. You feel the warmth of her breath against your palm as her lips open and she utters more lewd moans that she has failed to suppress. Her pussy clamps down around your dick as you pound it, Lana’s body being honest about its desires in a way she can never put to voice.

You can’t help but smirk. It’s pointless to muffle her cries. The door to Lana’s bedroom lies slightly ajar, and from the crack several wide eyes peer in at you. Her siblings were awake a long time ago, and try as she might to control herself, the sound of your foreplay had drawn their attention. Now they were watching everything. You know this, but Lana doesn’t.

With your free hand, you pull Lana’s legs wide, giving the voyeurs an unobstructed view of your thick cock pummeling their big sister’s pussy. The door creaks open another inch as their curiosity gets the better of them and they lean in closer. At the sound, Lana’s whole body stiffens, and she lets out a little muffled shriek of surprise.

“Game’s up,” you say, grunting as you continue to fuck Lana. “Open the door and come on in.”

Lana’s head whips back and forth in confusion, looking back at you and then over to the door again as it’s slowly pushed open the rest of the way. When her siblings shuffle into the room, guilt written all over their faces, she gasps in shock. You lower your hand away from her mouth - there’s no need to hide anything now - and grab both of her legs, pulling them as wide open as you can.

“Get out!” Lana cries in a panic. “Wh-what are you all doing here!”

But her protests melt into a particularly lewd moan as you give her a sharp thrust, the tip of your cock bumping hard against the back of her pussy. “They’re just curious. Let them watch; a good big sister has to be a teacher, right?” Then, looking at the huddled group of youngsters, you say, “Come on closer. Look as much as you want.”

Heedless of Lana’s distress, her siblings get down on their knees and inch forward, their eyes glued to the spot between her legs where your thick rod is thrusting wildly into her. Lana tries to close her legs, but your grip is too firm, and you keep them forced open. You feel her inner muscles quiver with desire as she instead covers her face; she’s about to cum despite her reluctance.

The moment you feel Lana’s body begin to shake with orgasm, you fuck your cock all the way into her so hard that she bounces several inches off your lap. Her pussy clenches down along your shaft, squeezing it intimately as she climaxes in front of all of her siblings. A moment later you grunt and pass the point of no return; your balls tighten as a thick blast of cum rockets up your shaft and deep into Lana, flooding her womb with your seed. She buries her face deeper into her palms as the two of you cum together, her legs spread wide for your innocent audience. Curious faces lean in closer, their eyes locked on the forbidden act taking place in front of them.

You’ve blown half of your load into Lana’s pussy when she shudders and bucks her hips. Without warning, your cock slips out of her and before any of them can dart out of the way, you’re spurting your load all over the faces of Lana’s younger siblings. They flinch, wide-eyed and open-mouthed, completely taken off guard as thick jets of hot spunk splatter all over them.

By the time your whole load is spent, Lana is coming down off of her orgasm. You hold her there, your hands hooked beneath her legs, holding them open as your cock softens and cum drips out of her well-fucked holes. The youngsters look up at the two of you in amazement. Lana’s face remains hidden behind her quivering hands.

“Looks like Lana’s a mess,” you say to your stunned audience. “Why don’t you all come clean her up?”

Lana shakes her head and moans as her siblings look back and forth between each other. Then, hesitantly but excitedly, they all scoot forward and lean in, taking turns licking their big sister’s pussy and your warm cum out of her. Before you know it, Lana is shaking and shivering again as the menagerie of inexperienced tongues forces a second orgasm out of her.

Your cock is already starting to spring back to life. “Good,” you tell them all, your voice soothing and reassuring. “Now, what shall we all do next?”
