Des:My sister is a weak girl, somewhat ignorant about sex and incest. When I taught my sister such false sexual knowledge, she innocently touched my back, so I became excited, and because I obeyed the pleasure and greedily asked for penetration, I had incestuous sex! It was so comfortable that I accidentally ejaculated vaginally, but I wasn’t afraid of getting pregnant. I want you to always be like this little sister who doesn’t understand anything!
