[Supe (Nakani)] The Story Of A Little Sister That Loves Her Big Brother [Suzuki Marmalade]

A cheerful schoolgirl comes home to find her big brother mid-masturbation—and rather than look away, she seizes the moment, turning his mortified stammering into the chance she has clearly been waiting for. An 'accidental' brush of her hand escalates fast: she grinds on top of him with hearts blooming in her eyes, proudly showing off her little pussy while he apologizes in panic, and by breakfast the next morning she's cheerfully asking whether his cock shot a big load overnight. With her phone never far from the action, every flushed, ahegao-twisted expression and desperate thrust ends up captured for her own private collection.
