We live in a country where, every day, new fertile people are chosen in the Fertilisation Lottery and become free use - anyone who wants to breed those people, is allowed to, regardless of relation or public setting. When I get the notification on my phone, I'm nervous and reluctant at first, but then you, my step-brother, tell me that you want to be the first to breed me. I open up about how I'd fantasised about being selected, before sucking your cock to get you hard and letting you breed me! I wouldn't want to get in trouble, after all...
