I don´t think, Renpy is the right engine for idle animations ... I don´t know how Renpy operates, but it feels like every click/action generates a new frame/image ...
I am in for some more audio ... asside from the moody BGM I´d like some ambient sound ... maybe birds and bees for the park, a busy croud for the market, waves and seagulls for the lake side, music and mumbling voices for the bar, etc...
Dripping sounds for an overflowing pussy are mere fantasy ... but Sammy might have thoughts about it ... "I like going commando, but I do not like it running down my thighs" when overflowing or on her period ... "Leaving wet spots where ever I´ve been sitting is kind of embarassing"
