You know I’d do anything for you step-brother… you know that right? Well I need you to do something for me. We need a sperm donor… and you’re the only one we can think of that we would want to do it. I know it sounds crazy but it just feels right to keep it in the family instead of inviting some stranger into our lives. And with you and me, it would just be sex between step-brother and step-sister, instead of another man so he won’t be jealous. It’s just to get pregnant…as a favour to me. I know it’s weird but would you please just do this for me? Just this one time… it’s not a sex thing… it’s just to get pregnant… mmm that actually feels pretty good. But it’s not about that… I just really want to have a baby… mmm… fuck me deeper step-brother.
