This video submission comes from a man who is training his sister-in-law and nephew, who have been repeatedly engaging in incest, as sex slaves. Confession/Baron Hanabusa (Uncle) Mari and Yuta (both pseudonyms) are the children of his late sister-in-law and brother-in-law. After they died in an accident, my childless wife and I took them in. My wife was a masochist, and as a sadist, I trained her as a sex slave. A few years ago, after my wife passed away from illness, I lived with Mari and Yuta. Soon after, I discovered their incestuous relationship. Although they weren't directly blood-related, they were my wife's nieces and nephews. These two siblings, as masochists, weren't satisfied with just the horrifying incest and kept tormenting each other. The sadist within me, upon learning their secret, whispered, "Make them happy, just like my wife, XX (wife's name). Both Mari and Yuta are perverted masochists. They're perfect for sisterly tit-fucking. The XX family line is full of slaves. You should dominate these two masochists and lead them to happiness." I gradually began training Mari and Yuta. When I fucked Mari in front of her brother, she cried out in a sweet voice. Despite saying, "Don't look... Yuta," Mari's pussy clenched tightly, gripping my penis. My penis, visible to Yuta, stood erect, overflowing with pre-cum. "What are you not looking at? You're squeezing my cock so tight. Yuta, doesn't your sister's pussy feel good? You must have fucked her many times before, right? You should touch that erect cock." "Yes..." "Mari, Yuta, you understand, right? You're forbidden from having sex on your own anymore. Mari's pussy is mine to use. Yuta, I'll introduce you to a new girl, a cute Dutch wife." Excited by my words, I fucked Mari. The semen I ejaculated inside her was then made to be cleaned by Yuta while she performed facial. "Look, Mari, you're cleaning the cock that you've soiled with your own juices." Following the oral sex etiquette I've taught her, Mari not only squeezed out all the semen from the base of my cock, but also meticulously licked the dirty balls and groin. "Yuta, your sister's pussy, mixed with semen, must taste good, right? But just licking isn't enough. You have to lick it with the intention of making your sister cum
