[Sistny] Big Sister Single-Mindedly R*pes Little Sister: Drunk Nayu [Full Color]

Nayu comes stumbling home drunk to her little sister Yun's warm welcome, and the alcohol strips away every inhibition before the night is over. A cheery greeting and a thumbs-up give way to relentless, apologetic rubbing that leaves Yun's thighs trembling and her weak protests dissolving — even as the two sisters panic about Toyo noticing what they're doing. By the time Nayu breathes her sorry, it's Yun arching back and begging to be filled, with a closing tease hinting that Toyo wants her own turn with the pair.
