Fics like With a little brother, you just have to do these kinds of things sometimes

Cathy’s younger brother shows her a video on his phone that’s kind of weird, all swirling colors and wavy spirals. But it is pretty relaxing and he tells her not to think too hard about it, so that’s okay. Afterwards Cathy suddenly remembers something—she needs to clean her brother’s ass with her tongue. It’s a bit weird that she has clear memories of doing that all the time, but can’t think of any specific occasion—but why try to piece things together when there’s work to be done, work that requires a loving sisterly tongue.
