"Yes, yes! More! Harder!" Riko cries out, her voice echoing through the room as she meets every thrust with eager hips and greedy kisses, lost in the exquisite sensations of finally surrendering to her deepest desires.

"Ooh, right there! Keep going!"

Her fingers dance over his skin as she pulls his shirt off, revealing his defined chest and flat stomach. She can feel her own breath hot against his skin, sending shivers down his spine. "It feels so good," she whispers, leaning in closer to brush her lips against the skin of his collarbone.

With a gentle tug, she pulls off her oversized t-shirt as well, exposing her naked body to him for the first time.

Her nipples harden into tight peaks as she feels his gaze slide over her body, taking in every curve and detail. She bites her lip nervously, waiting for him to react. When he says nothing else, she decides to take matters into her own hands, reaching out to cup one of his erect nipples between her fingers.

"Like this?" she asks breathlessly, rolling it gently between her thumb and forefinger. "Is this okay? Or should I...?"

A smile tugs at the corners of Riko's lips. "Yes... much better," she replies, her voice thick with emotion. "Thank you."

She arches her back again, moaning loudly as you continue to thrust your finger in and out of her tight warmth. Her body quakes and shudders with pleasure, and she curls her toes, digging them into the sheets.

Your lips meet hers once more, hot and hungry. She responds with equal passion, their tongues tangling together as they explore each other's mouths. Your free hand roams freely over her body, tweaking her nipples through her shirt, caressing the soft skin of her belly.

Riko's nails scrape down your back, urging you on even further, her hips bucking up off the bed in time with your fingers.

Her touch wakes you up, and your eyes flutter open to find Riko laying beside you on the bed, her hand wrapped around your cock. For a moment, confusion washes over you before comprehension dawns and sheer desire takes hold.

"Riko..." you breathe out, arching your back into her touch. She smiles down at you, her eyes filled with wanton lust. "I'm sorry," she whispers, "I couldn't resist."

"I know it isn't," she agrees softly, her voice barely more than a whisper. "But I can't stop thinking about how good it felt when you touched me earlier. I need this... Please." Her fingers tighten around your shaft, urging you to harden further in her grip.

As you slide under the covers of your bed, the soft fabric feels cool against your overheated skin. You lie there in the darkness, listening to Riko moving around in the other room. The sound of her quiet footsteps and occasional rustling noises only serve to heighten your arousal.

You close your eyes, trying to banish the images from your mind... but it's no use. You can feel yourself growing hard beneath your sheets, your heart racing with desire for her.

An hour passes, and you finally manage to fall asleep. Your dreams are filled with images of Riko, her body moving in a sensual dance that leaves you aching for more. When you wake up the next morning, she's already long gone from the house, off on some errand or another.

You take a quick shower and get dressed, trying to push aside the memories of last night. You don't want to think about what she was doing... but you can't help it.

You watch Riko's body relax in the afterglow of her orgasm, her breathing slowly returning to normal. For a moment, she seems unaware of your presence in the room, too lost in the haze of pleasure that has just washed over her. Then, her eyes flutter open and she looks up at you, confusion and surprise written across her flushed features.

Your heart races as you meet her gaze, unsure of how to react or what she might say.

Riko's cheeks flush an even deeper shade of crimson as she takes in the sight of you standing there, your cock still hard and glistening with cum. She clears her throat awkwardly, trying to find words but only managing a stutter. "B-Brother... I-I'm sorry...." Her eyes dart around the room, searching for something else to focus on besides you and your obvious arousal.
