[YuriXkiss] Aqua x Ruby (Oshi no Ko) [Decensored]

Ruby Hoshino is caught mid-change by her brother Aqua, whose playful greeting curdles into something predatory as he forces himself on her despite her frantic protests of 'Aqua, you can't do that!' Pinned and overwhelmed, she begs him to stop, but he takes her roughly until she's left face-down and gasping on the floor, dripping, while he breathes that he's not done yet. A closing sketch seals the bitter aftermath, Ruby sobbing 'Aqua, how could you!' as this raw sibling encounter ends in tears.
