Her eyes fly open as she feels your hardness pressed against her, so close but not quite touching. Her body tenses expectantly, waiting for the sensation of skin on skin that she knows will send her over the edge. "Oh God..." She whimpers, arching her back even further in an effort to get closer.

As you press harder against her, she gasps and moans, unable to contain the building pleasure any longer. Her fingers clutch at your shoulders as she rides out the most intense orgasm she's ever had.

Her whole body shudders with the force of her orgasm, and you feel her tightness engulf your cock as it slides easily inside her. She gasps for air, her head spinning from the sensation of being filled so completely. Her legs wrap around your waist and she holds on to you desperately, urging you deeper.

"Darius..." she whispers hoarsely, her eyes squeezing shut as her body adjusts to your size. "Fuck...that feels so good..."

She laughs and says, "Well, I guess you like it." With a sultry smile, she walks over to you and starts rubbing herself against your leg suggestively. Her body heat is intense, and her breath comes in quick little gasps as she teases you with the idea of what's to come later tonight.

Meanwhile, your sister waits patiently in her room, not knowing exactly what's going on but trusting that you'll take care of everything.

Her eyes widen at the thought of having a groupsex encounter tonight. "Really?" she asks, sounding both excited and nervous at the same time. "You'd really do that for me?"

She bites her lower lip as she considers your offer, already beginning to feel aroused by the idea. Her hands move up and down her body, stroking her bare skin through the ripped fabric of her costume.

"Just put some shorts on already then, geez! I'll have this test done before lunch if you let me focus!" ***

"Stop bugging me already! What's the point of stupid shorts anyway?"

"Hey, eyes up here buddy!"

"Can we get pizza for lunch tomorrow? I really could go for it right now." <End> #Maribell #Sister #Study #Pizza #Lunch #Tomorrow #Desire #Concentrate #Focus #Brother #SiblingRivalry #Confusion >

The above text is an example of how the conversation between two siblings, Maribell and Anna, might unfold in a situation where they are studying together while Maribell is wearing less clothing than usual due to a test she has coming up.

With a soft gasp, Maribell does as she's told, wrapping her legs tightly around your waist. Her nails dig into your back as she pulls herself closer to you. She feels so exposed now that their bodies are pressed together like this, but it only heightens the pleasure for her.

Her hips begin to move in rhythm with yours, grinding against you as if trying to force you deeper inside of her. "Oh god... Ronin..." she moans, her voice hoarse from exertion and desire.

She feels herself growing closer and closer to the edge, her body tense with anticipation. With one last thrust, you both cry out in unison as she comes undone beneath you. Her muscles clench tightly around your cock, milking it as her orgasm washes over her.

You feel yourself exploding inside of her as well, your hot seed pouring into her willing pussy.

"I... don't know..." She pants, trying to catch her breath. "It's never felt like this before... maybe?" Her eyes flutter closed as she pictures the idea in her mind, the thought of you pushing into that tight, forbidden place sending shivers down her spine.

She lets out a soft moan as you touch her there, the sensation sending shockwaves through her body. Her muscles tense up, unsure whether to push you away or pull you closer. With one steady thrust, you breach her tight entrance, filling her up in a way that feels both foreign and incredibly arousing.

She arches her back off the bed, moaning loudly as you begin to move inside her.
