The bathwater sloshed lazily around them, a silent witness to the steady rhythm of Reina's fingers continuing their slow, deliberate exploration of Mizuki's chest. She hadn't stopped—not even for a moment. Her thumbs circled Mizuki's nipples underwater with frustrating consistency, coaxing soft gasps and twitchy shivers from the smaller girl every few seconds.
"You're so easy to tease," Reina murmured with a smug grin, her lips brushing Mizuki's ear again. "It's like your body betrays you even when your mouth says 'no.'"
"Y-you're doing this on purpose…"
"Obviously."
Reina's hands gave another gentle squeeze, molding Mizuki's modest breasts in her palms, the slickness of the bathwater making her every movement feel exaggerated. She pinched a nipple softly.
"Let's play a game," she whispered.
"N-not another game…" Mizuki whined.
"Oh, this one's easy," Reina cooed. "You just have to answer a question."
Mizuki flinched as Reina pinched again. "Nnnh—what kind of question?"
