MIAA-150 For my little brother who wants to become an AV male actor, I'll be his practice dummy for ejaculation and sex. Rinne and Tuka

My delinquent brother suddenly said, 'Sis… I want to become an AV male actor!' This won't do; I have to stop him somehow…! But when I made him practice bukkake, he was surprisingly good at it! He also shoots properly during blowjob practice, has a great erection too… Hey, this kid might actually be talented? Explosive breast sex practice, first-time sex lessons, even taboo incestual in-the-vagina lessons! Even though I only have a lewd body and perverted techniques, let's work together to make him into a respectable male actor☆
