POV: we are siblings who have always been super close and supportive of each other. i just found out from mom that you broke up with your girlfriend. good thing i didn’t like her anyways, she was always stealing you from me) so i rush to your room to do whatever i can to cheer you up. you tell me that your girlfriend and you broke up because you wanted different things, you wanted to settle down and start a family (something i always knew and wanted you for) and your girlfriend wasn’t ready (but that’s okay, because sis is hehe). after hearing this i start coming on to you, telling you that we should be together like we always have been. We have always been together and way closer than any other siblings (we were each other’s first kiss after all). We used to dream of being together, but that all changed when your girlfriend arrived. Now that she’s finally gone, i decide it’s time for us to finally be together and take what’s mine. i start by giving you a hand job, dirty talking  and dissing your now ex (my jealousy finally showing). For the dirty talk i love to emphasize the fact we are siblings and how this is so taboo but that’s what makes it perfect, and that your ex is inferior to me in every way. i begin giving you a blowjob - something your girlfriend never did, and when i find this out it just adds fuel to our fire. During the blowjob and after some dirty talk i start to beg for us to fuck, i want to fulfill your dream of starting a family. The sex starts with me on top riding cowgirl, lots of dirty talk and mention of possible pregnancy. We move to missionary where we continue to dirty talk ( things like, our bodies are the perfect match for each other, sibling sex makes it’s hotter, the thrill of pregnancy) final scene is both our favourite position doggy style (laying on stomach/planking doggystyle). i begin to beg you to finish inside me for we both desperately want to get me pregnant and start a perfect family. It ends with a creampie and wraps up with some wholesome sibling dirty talk and how you and i will be the perfect for each other
