Ah, I want to impregnate my stepsister 100%... My younger stepsister, Arisa Aizawa

Description

My step-sister Arisa, younger than me, is known for her refined looks and friendly demeanor—even outside our family. Since ○○○○○hood, I've been constantly compared to my older brother, which has always annoyed me. Now that I have a wife to boast about, the comparisons happen daily. But this time, I don't mind so much. Because my step-sister and I share a secret the family doesn't know. I accidentally witnessed her affair with her own brother. Now I can control her with that knowledge. While I feel superior to my accomplished brother, I've recently realized I'm more skilled in sex than he is. At first, she pretended to resist, but it's obvious she's completely hooked on my impregnation training. Now, even as she pretends to resist, she sends me submissive glances, her love juices seeping out, craving to be taken hard. I'll grab her F-cup breasts, so out of place on her proud, slender body, and train her however I please. Someday, I'll show this to my brother. Come on, sis. Today, I'll give you plenty of impregnation training.
