I'm secretly dating my stepsister, keeping it hidden from my parents. Usually, I'm careful not to get caught, only sneaking in some affectionate moments. But when my parents go on a trip and leave the house empty, I can't stop! My usual restraint crumbles, and I keep having sex with my stepsister over and over. The more we do it, the deeper our bond becomes! Getting pregnant is honestly scary, but I just naturally end up doing it inside her. This feeling of having a girlfriend under the same roof is incredibly happy.
