I have a really scary sister. But whenever she gets drunk, she becomes really sweet to me and wants to drink my sperm! "Hey, hey, let me have your sperm! Get your dick out quickly." My sister, who is usually scary, gulps down my semen with a smile! Before I knew it, I was expecting my sister to give me a blowjob... Even now, I continue to have sex with my sister, who is usually bossy and scary, without telling my parents.
