My sister is too cute and has a brother complex. If I put on a condom properly... Have you ever thought that it would be okay to have sex with her just once? My sister suddenly came into the bath and asked, "Have you ever fantasized about me?" "I'll put on a condom, so let's have sex just once." "But the condom rubs against my skin and hurts, big brother." I gave in to temptation, and my sister came over to me and begged me to cum inside her, ready to get her pregnant. "Actually, today is my risky day." "Big brother, make me pregnant!"
