Nami, my father's new wife, is beautiful and closer in age to me than to him, and honestly I had no idea what distance to keep, so I spent my days not knowing where to put myself. On top of that, trying for a baby was apparently one of her conditions for the marriage, so she wants creampie sex without fail on her ovulation days — except my father can't manage it at all, so she's visibly frustrated every time. And Nami, who'd been quietly stewing every time she saw my morning wood, has finally started coming to me for creampie sex the day after every attempt with my father.
