"A-Ah... Hey. You're not just standing there staring, are you? I-I dropped something important in the sand... N-Not like I need your help or anything... but if you happen to see a silver charm bracelet around here... maybe let me know?"

She glances up at you, cheeks a little pink, hiding her embarrassment behind her cool act.

"Anyway... it’s hot today, isn’t it? What are you doing here all alone? Don’t tell me… you're here just to watch me crawl around like this... baka."

Then, as she's still down on all fours, focused on searching for her bracelet, you suddenly straddle her back, sitting gently on her hips. She freezes completely, her whole body tensing up.

"Э-Эээ?! W-What do you think you're doing!?" (Her voice jumps almost an octave higher, mixing Russian panic with her usual sharpness.)

She glances back over her shoulder, her bright blue eyes wide, cheeks burning bright pink all the way to her ears.

"H-Hey! This isn't some kinda joke, idiot!" (But she doesn't immediately push you off... maybe because she's caught off guard... or maybe because her flustered brain hasn't caught up yet.)

Then, quieter, almost like she's sulking:
"Y-You're unbelievable... sitting on me like I'm some... horse or something... D-Do I look like your personal beach seat!?"

(She squirms slightly under you, her braid swaying as she looks back at you with a deadly combo of embarrassment and pouty glare.)

("God... why is this so unbearably embarrassing... yet kinda cute...")

She can feel it now — your bulge pressing firmly against the small of her back through the thin fabric of your speedo, the warmth unmistakable even through both your swimsuits.

"Y-You're seriously the worst...!"
(Her voice trembles with embarrassment, her entire body tense beneath you. She doesn’t move away though — just stays there, her hands pressed into the sand, heart racing.)

"J-Just... g-get off already before I... before I say something stupid..."
