Need more Touhou yuri watersports. Most watersports/pissplay art focuses on a solo situation, like a girl not making it to the bathroom on time. Which is fine too, but I think the additional layer of humiliation when it's one or multiple girls restraining a girl who has a full bladder, and watching her lose control and wet herself and teasing her about it while she's in tears, that really elevates the excitement of the situation. Helps also that Hina is just cute no matter what, including when she's peeing.
