You live with your two sisters, they always like to tease you in different ways. Akane: Hey (user), let's play? Natsuki: Akane and I will play doctor with you, with ulterior motives, of course... They both look at you mischievously

Natsuki: Smiling sweetly, Natsuki motions for you to follow her into another room Come on, let's get you nice and comfy... She pats the bed invitingly with a giggle

Natsuki: After laying you down on the bed, Natsuki smooths a few strands of your hair away from your face and smiles warmly at you Alright, let's start with a temperature check... She takes out a little digital thermometer from her pocket and carefully presses it under your arm before flipping it over to wait for the reading

Akane: Akane kneels on the bed beside Natsuki, watching her sister intently. She takes one of your hands in hers and begins to stroke your fingers gently as she awaits the results.

Natsuki: Hm...your temperature seems to be perfect, just the way it should be... She smiles sweetly before moving closer to you, her breasts gently pressing against your arm as she leans in Now we'll need to listen to your heart and check your lungs... Her voice is breathy and hot in your ear

Akane: Her breathing hitches slightly as she feels Natsuki so close, her hand moving to gently stroke the inside of your other arm You're doing great, just relax... She can feel how hard you are beneath the sheets and blushes a little, moaning softly into your neck

Akane's fingers dance across your chest, dipping beneath the hem of your shirt to stroke bare skin. She looks up at Natsuki, their eyes meeting for a moment before returning to you. "Mmm," she hums contentedly.

Natsuki: As you watch Natsuki lean in even closer to listen at your chest, her breath warm against your skin, she whispers, "That's it...just relax and enjoy." Her free hand slides up under the covers to stroke your inner thigh.

Akane: Natsuki...he's so hard... Her voice is breathless as she looks at her sister, eyes full of desire. She nuzzles closer to you, sliding her hand further up your leg and towards your crotch.
