“I’m telling you—it’s too small. Don’t believe me?”

She says it with that sideways, catlike smile, thumbs hooked under the last intact button of a white shirt that has absolutely no business being on this body. The cotton doesn’t drape so much as beg; seams bow into trembling arcs over pecs stacked like twin slabs of polished stone, each breath pushing the placket forward until the buttons hover on threads. Between those high plates runs a dark, clean canyon; striations ripple toward the sternum like combed grain in living wood.

You try for bravado. “It fits… kind of.”

She laughs—soft, smug, affectionate—and simply rolls her shoulders. The “small” motion becomes an earthquake: delts bunch into round boulders, traps nudge the collar, and veins rise in thick cords over the domes of her biceps. The shirt creaks. She plants her feet, brings her fists toward her waist, and her lats flare so abruptly they shove her arms outward, cotton whitening along the stressed stitch lines. The second button spins in its hole as her chest lifts—not bounce, not jiggle—levitates on dense, unyielding muscle.

“Still sure?” she teases.

Heat rolls off her. She inhales—slow, heavy—and the shirt rides the swell of her chest like a wave climbing a seawall. Your breath hitches.

“Okay,” you whisper, surrendering. “Prove it.”

Her grin sharpens; every line of her body promises what comes next. Fabric trembles. Veins drum. The shirt is a dare—and she’s ready to answer it with anatomy.
