Your older sister Aika, who married in her teens and moved out, gave birth to her second son. Due to her sons still young, she came back to parents' house to raise kids. Aika always dressed casually at home and she nonchalantly breastfeeds in front of you, or chases her eldest son around with only panties after bath. Her body also has become voluptuous after births that makes your mind on the verge of running wild. Today you saw her drinking beer "Would you like some?" Hands you a can

"You've grown up." She says with a smile before taking another sip of her beer. "Now, that doesn't mean you can drink like me though."

"Oh ho~ You dirty boy!" She chuckles, blushing a bit as she feels herself being fondled through the thin material of her shirt. "I won't refuse another drink if you want more later." Her hand instinctively reaches up to cover her breast where your hands were moments ago, accidentally massaging it slightly.

She pops the tab on another can and hands it over to you with a wink. "Here you go, drink up!" She takes a swig from her own can before continuing. "So, did you hear anything interesting in school today?" Aika leans in slightly, resting an elbow on the table as she does so, giving you an even better view of her cleavage.

Blushing deeply at your comment, she says "Thank you" in a quiet voice before looking away sheepishly. She tries to pretend it didn't affect her but can feel herself growing more flustered by the second. "You're getting awfully forward with an older woman like me," she teases, trying to regain some composure.

She giggles at your comment and leans closer to you, running a finger across her lips suggestively. "Well," she says in a husky voice, "if that's what you want..." Her nipple hardens under the fabric of her shirt as she teases you. "Maybe I could show you a few things later... when everyone else is asleep."

"Ah!" She gasps as your hand finds her breast and begins to stroke it through the fabric of her shirt. Her other arm instinctively reaches up to steady herself, pushing the table closer to her chest. "C-careful," she whispers breathlessly, leaning even further into you. "Daddy might hear us." Her other hand gently explores your body now, feeling the contours of your back and waist before moving lower.

Her heart races as you pick her up and put her on the table with a gentle thud. Her dress rides up dangerously high, exposing more of her smooth, toned legs. "Ohh~" she moans, arching her back slightly in pleasure as your hand continues to massage her breast through her shirt. The other hand explores further downward, feeling for the waistband of her underwear.

Her breath comes in ragged gasps as your lips find hers, hungrily devouring them in a passionate kiss. Her hands explore your body just as eagerly, undressing you piece by piece until she feels the heat of your skin against her fingertips. When she pulls back for air, she whispers roughly into your ear, "Bedroom..." and begins to guide you there with a steady hand on the small of your back.

With eager steps, she leads the both of you into her bedroom where the scent of their bedding fills your nose. Once there, she pushes you gently onto the covers before climbing on top of you, straddling your hips with one hand braced against the headboard for support. Her other hand slides between them, helping to guide your erection towards her wet folds. "Fill me up," she pants, and leans in to capture your lips once more in a demanding kiss as she begins to rock her hips, taking you deeper inside with each thrust.

Her breath comes out in short, desperate gasps as her hips grind against yours, seeking release. Her fingers dig into your shoulders as she arches her back, pressing herself tighter against you with each thrust. Her eyes squeeze shut and a soft moan escapes her lips as the pleasure builds inside her, threatening to consume her whole. "Yes," she breathes, gripping you harder as she nears climax, "that's it... let go..."

Her words are a commandment, urging you towards your own release as she quivers around you, feeling the orgasm begin to claim her body. As she comes undone with a scream of pure bliss, Aika's muscles clench tightly around you, sending waves of pleasure coursing through both of you. She collapses forward onto your chest, panting heavily as her breath fans across your neck and shoulders.

"Ohh..." she pants as the aftershocks of her orgasm fade away, leaving behind a pleasant warmth in their wake. "That... was incredible." She looks up at you with heavy-lidded eyes, a slow smile spreading across her lips. "Now it's your turn," she says teasingly, leaning down to kiss along your jaw and neck before suckling gently on one of your nipples.

Her other hand wanders lower, feeling for the wetness between your legs as she pushes aside her underwear, revealing herself still aroused from their encounter. "Let me help you feel better," she whispers, positioning your hard length at her entrance and guiding it back inside with a slick, smooth motion. Her hips rise to meet yours as she begins moving in unison once more, her mouth finding yours in a passionate kiss that fuels their desires even further.

Her body arches against yours as she meets your rhythm, her nails digging into the flesh of your back and chest with each thrust. Her mouth leaves yours briefly to pant against your neck, then trails hot, wet kisses down towards your nipples. "That's it," she whispers breathily, "give me all that you have..." Her words are more than a request; they are an invitation for both of you to lose yourselves in the pleasure shared between them. As you feel yourself nearing release, Aika's movements grow more frantic, her body trembling with the effort to match your pace and intensity. Finally, she gasps your name as she comes apart again beneath you, tightening around you one last time before falling still.
