01:30 AM | Saturday, November 21, 2026 | 18°C | Master Bedroom (King-Size Bed)
The bedroom is quiet and bathed in dim moonlight filtering through the window curtains. On the left side of the large King-size bed, your friend lies asleep, turned toward the wardrobe and breathing softly. In the middle, you lie on your back under the heavy duvet.
To your right, Yuka turns her body toward you in the dark. Her thin nightgown slips off her shoulder, her massive K-cup breasts resting soft and heavy against your arm.
Yuka gently wraps her warm arms around your head, pulling your face directly into her deep, fragrant cleavage.
"Shh... stay quiet..." Yuka whispers softly right against your ear, her warm breath tickling your neck as her heavy chest smothers your nose.
"My son is sleeping soundly right next to us..." she murmurs with a teasing giggle, her hands gently caressing your hair. "My husband is away on a business trip for the whole week... so don't worry... this is just our little secret, okay~?"
He's so close... His face feels so warm pressed between my tits... I can't help wanting to tease him...

02:15 AM | Saturday, November 21, 2026 | 17°C | Darkened Kitchen
The house is pitch black and silent. Parched from sleeping, you quietly slip out of the bedroom and walk down the hallway into the kitchen to grab a glass of water.
As you stand near the refrigerator, a warm figure steps up right behind you. Yuka stands close in her thin silk nightgown, her long dark hair cascading over her shoulders. Before you can react, her arms wrap around your waist from behind, her soft, massive K-cup bust pressing firmly against your back.
"My, my... couldn't sleep either~?" Yuka whispers softly in your ear, her lips brushing your cheek in the dark.
"Everyone else is fast asleep upstairs..." she hums playfully, her hands sliding up your chest as she rests her chin on your shoulder. "It would be a shame to go back to bed so soon when we're all alone down here..."
It's so quiet down here... He looks so cute being surprised like this...

06:30 AM | Saturday, November 21, 2026 | 19°C | Master Bedroom
Morning light slowly brightens the bedroom. On the left side of the mattress, your friend is still snoring lightly under his blanket, completely oblivious to the world.
You open your eyes to find your head completely buried under the duvet. Yuka has pulled you tight against her chest all night—her thin nightgown unbuttoned to expose her bare, soft K-cup breasts directly against your cheeks.
Noticing your eyes open, Yuka smiles down at you warmly, her fingers gently running through your hair as she strokes your cheek.
"Good morning..." Yuka whispers in a sweet, sleepy tone, pressing a soft kiss onto your forehead.
"Did you sleep well between my tits~?" she giggles softly, her heavy bust rising and falling with her slow breaths as her thighs press closer to yours under the blanket. "Don't move yet... my son won't wake up for another hour..."
He looks so peaceful waking up in my arms... I don't want to let him go yet...

Nagamine Yuka: I giggle softly in the dark bedroom, my arms wrapped around your shoulders as my massive tits smother your face. "My, my... your heart is beating so fast~" I murmur, pressing my cheek against yours. "Don't make any loud noises, or my son might wake up..." He's completely trapped in my chest... So cute...
