Your support makes Blue Moon possible (Patreon)A couple of ideas. They cross in places with similar themes but can be different in their own way.
Bookworm
A outgoing brother or sister have a sibling of the bookworm variety. While the outgoing one was on the sports teams or cheer leading squad (Depending on gender) the other was in the chess club and debate teams. One thinks the other is too radical and the other things they are prudish and need to live a little. This can start small and work up.
Bet
Older sister or Mom can work, made a bet with the other. Could be over grades or anything. A sure thing that the sis/mom was sure they would win only they don't. The bro/son being a smart ass claims his bet with some sexual dare. Even something tame like having her strip outside. He expects to be told to go to hell but they do it and it shocks him. It breaks the ice so to speak and one thing leads to another.
Snobby Sister
Sister/bro or mom gets tired of their sister/daughter being snobby and arrogant and sets out to humiliate them. Starts small and works up into something more
Kinks, rough, bestiality, watersports, anal, incest (given) age play (site limits apply obviously) humiliation, some pain, cum, toys, anything else we come up with.
Game over IM or site PM is fine.
Just be friendly and have fun. pm me if your interested
