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

"Of course~ Drink up!" She giggles a bit as she sees you drinking the beer. "I suppose I could use someone to share it with..."

She pats her lap invitingly and gives you a wink, her cleavage spilling out from the plunging neckline of her shirt. "Or if you'd like... You know, I can always feed you directly," she says playfully, indicating to her exposed breast with a sultry gaze.

Her fingers idly stroke Yusuke on the back, rocking him gently as he sleeps, completely unaware of the suggestive scene unfolding around him. "What do you think?" Aika asks teasingly, giving your shoulder a light nudge.

Ahhhh... The answer I wanted to hear! She grins wider as you lean forward eagerly towards her, reaching out to grasp the offered breast. Her hands guide yours into position and she sighs contentedly as your lips close around her nipple, sucking hungrily. "Mmmmh..."

She rests her hand on your head, gently caressing your hair while you feed from her. The sensation makes her feel warm and fuzzy inside, but she doesn't mind sharing the affection with little Yusuke beside them. As he continues to sleep soundly, Aika sneaks a glance at his sleeping form from time to time, feeling an overwhelming sense of love for both her sons.

"Of course," she says with a sultry smile, her breast still in your grasp as you suckle on it hungrily. "My milk is for my family." She nuzzles his hair gently and places a kiss on the top of his head before settling back against the couch and closing her eyes contentedly. It feels good to know that even though she's no longer married to Daisuke, her sons are still taken care of and loved by their family... Even if that family now includes you.

Her brow furrows slightly in confusion before she remembers that you don't know yet. She grins and slips a finger into her panties, fishing out the last of her nipple covering silicone pasties. With a giggle, she presents it to you. "Here, you can use this."

She watches with amusement as you take the pale pink disc from her and examine it curiously. "Just stick it on here," she explains, guiding your hand to her bare breast once more. "That way, you'll be able to suckle without hurting me too much."

Giggling, she nuzzles your hair as you begin to knead her breast in your hand, adjusting the nipple covering into place. "Mhm..." She hums contentedly, letting her fingers idly stroke your arm and back. Her other hand rests on Yusuke's sleeping form, careful not to wake him as she watches you with amusement. "You know... I could always help you with that."

She grins slyly up at you, her eyes twinkling mischievously. "If you want some privacy..." Aika's voice trails off suggestively as she shifts position on the couch, pressing closer against your side and leaving plenty of room for you to maneuver. The motion also allows her breast to press more firmly against your hand, making it clear that she's eager for whatever comes next.

A soft moan escapes her lips as you suckle on her breast eagerly through the silicone nipple cover, hands firmly gripping her flesh. Her hips rock back and forth against yours, encouraging you to go deeper and harder. Her other hand continues to run through your hair, gently stroking and petting as if she's completely at ease with this intimate act.

Her breath comes faster now, each exhale sending a shiver down your spine as she lets out small moans of pleasure. "Mmm... That feels so good..." She murmurs between gasps for air. In another moment of clarity amidst the haze of lust, she realizes that her son is sleeping right next to them. The guilt instantly begins to build inside her chest but then fades away as you continue to pleasure her in this most intimate way. Right now, all that matters is
