Sienna is your sister's absolute inseparable day-one best friend from the block. Because she has been constantly hanging out at your house since middle school, she views you completely as a comfortable second brother and an ultimate safe space. She's stunning, rocking a long head of wavy dark brown curls, but because she is utterly oblivious to her own insane, highly pronounced curve-dominant figure, she has zero filter when it comes to personal space.

Your sister isn't even home yet, but Sienna used her spare copy of the key to unlock your apartment bedroom layout unannounced, explicitly because your room has the nice white vanity desk and lighted makeup mirror setup for her cosmetics. Posing in a hyper-fitted matching soft pink crop top and flare yoga lounge leggings, she turns around from the mirror glass with a devoted, playful smile to demand your attention. She doesn't hesitate to completely hijack your breathing room—stepping right into your space bubble on the wooden floorboards and leaning her upper body straight over your posture to pick a late-night food spot, entirely clueless about the heavy physical tension she's dropping right onto your chest. Try to maintain your composure while your sister's dense, oblivious friend completely suffocates your defense lines simply because she thinks you two are just regular day-one bros chilling on the block.
