"Yessss... My sister!" She moans loudly as you continue to take her roughly, pushing her closer and closer to the edge. Her hips buck against yours, meeting each thrust with equal force, her fingers scrabbling at the couch cushion in desperation for something to hold on to. "Fuck me harder..." she whispers hoarsely, her voice trembling with need.

With one final thrust, you claim her, sending her careening over the edge into a shuddering orgasm. Her body convulses and quakes beneath your touch as she cries out your name in ecstasy, a thin line of clear fluid trickling down her inner thigh as her pussy spasms around you.

Her grip on your hair tightens painfully, but you don't let go--her pleasure is too exquisite to ignore.

Without warning, Riko presses her body against Samantha's, trapping her between them. She grinds her hips against the other woman's helpless form, moaning into her ear as she begins to thrust. Samantha cries out in pain and fear, tears streaming down her face as she feels Riko's latex-clad body sliding against her own.

"That's it," I say, my voice low and menacing. "Let her feel how much you want to hurt her."

As Riko continues to grind against Samantha, I reach down and begin to stroke myself through the latex of my suit. The sight of their struggling bodies together has me close to climaxing already, but I want to make them both suffer first.

"Riko," Samantha gasps between sobs. "Please... please stop..." But her words only seem to fuel Riko's lust. She growls low in her throat and thrusts harder against Samantha, grinding their bodies together with increasing force.

Riko swallows hard, her throat feeling impossibly dry as she considers the possibilities. "I-I could... suck you off," she whispers hoarsely, wincing at the words even as they leave her mouth. Her cheeks flush hotter still with shame and desire, but there's a determination in her eyes now that wasn't there before.

She waits for your response, her heart racing in anticipation of what you might say or do next.

With trembling hands, Riko reaches up to push the t-shirt off of her shoulders, revealing her lithe body and small, firm breasts. She wriggles out of the garment until it pools around her waist, leaving her completely naked except for a pair of panties that ride low on her hips. Her nipples are hard little buds pointing toward the ceiling, and she can feel the wetness between her legs as she anticipates what's about to happen.

"L-like this?"

"L-like this?"

Her voice cuts off as her body tenses and convulses around your fingers, her orgasm crashing over her in waves of intense pleasure. Her hips buck wildly against your hand, her cries of release echoing through the room. She shudders and quiets, spent from the climax but still eager for more as she comes back to reality, panting heavily beside you beneath the covers.

Her fingers slowly uncurl from where they've dug painfully into your skin, leaving behind a trail of blood beaded on her knuckles. She glances down at the evidence of their rough play, then back up at you, unsure of how to feel about what just happened. Part of her wants more, but another part is scared by the intensity and wantonness of it all.

"W-was that okay?"

Riko nods hesitantly, still unsure but eager to please you. She takes a deep breath, trying to steady her racing heart and the tremors running through her body. "Okay," she whispers softly, her voice barely above a whisper as she licks her lips nervously. Her fingers trace light circles on your forearm, feeling the warmth of your skin against hers.

She glances down between you, eyes flickering over the bulge in your pajama bottoms before looking back up at you, searching your face for some sort of sign or reassurance that this is what she wants to do. Her heart thunders in her ears as anticipation and desire mix together in a heady cocktail, making it hard for her to focus on anything but the sensations building inside her once more.

You feel her body begin to relax against yours as the realization sinks in that you're not going to push her away. She shudders with relief and exhaustion, her grip on your shoulders loosening ever so slightly. "I just... I need it," she whispers hoarsely, her voice raw from the tears and the effort to stifle her cries of pleasure.

Her movements become less frantic but no less urgent, seeking out release from the ache that burns within her.

With every thrust against your hardness, her body trembles and quakes with the need to be filled. The sensation of being touched in this forbidden way sends waves of pleasure coursing through her, making it harder for her to focus on anything but the release that seems so close yet still out of reach.

Her moans escape her lips unbidden, muffled against your shoulder as she struggles to keep quiet. Her hips buck and grind against yours, seeking more friction, more contact.
