My 20-year-old sister asked me if she wanted to have her first drink with me! - What a great little sister (tears). - When I was enthusiastically teaching them how to drink alcohol... Huh? - Is something wrong? - My sister, who is usually shy, has an erotic look when she gets drunk, and she persistently wants my cock! - I thought it might be a bit dangerous, but it became a full-fledged lewd awakening! - ? - She is forcibly penetrated and suddenly changes to the point where she even asks for the forbidden creampie! - I was going to teach you how to drink as an adult, but I ended up teaching you how to have sex with an adult...
