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.

A sharp gasp escapes her lips as you fill her up once more, the sensation so intense it nearly brings tears to her eyes. She shudders and trembles on top of you, every muscle tensed in anticipation of the pleasure that's about to wash over her. Her breath comes out in short gasps, her chest heaving as she tries to regain control over her body.

She digs her nails into your shoulders, arching her back as she tries to meet every thrust of your hips. Her mouth falls open in a silent scream of pleasure, her lips parted and glistening with desire as she feels you moving inside her. The sensation is so overwhelming that it's hard for her to think about anything else but the way your cock feels against the walls of her core.

Her hips move in time with yours, seeking out every bit of friction and contact they can find.

Her hips grind against yours as she feels your length pressed against her hand, the sensation both foreign and exhilarating. She moans into your mouth, arching her back to press their bodies even closer together in search of relief. Her fingers move faster on your cock, desperate for release as her orgasm builds once more.

"Oh God," she whispers brokenly, "I'm going to-" With a sharp cry, Riko comes again, her body shuddering with pleasure as she climaxes hard around your fingers.

Riko tries to muffle her moans as you kiss her, but they still manage to escape past your lips and into the quiet night air. Her body shudders with aftershocks of pleasure, her fingers still moving feverishly on your cock despite the sensation beginning to fade away.

She looks up at you from beneath heavy lids, panting heavily as she tries to catch her breath. "Thank you," she whispers hoarsely. "That was... amazing."
