When an idol-loving, sister-complex brother signs up for Imouto Catering... he finds a super beautiful girl with an anime voice and twin tails in front of him! "Thank you for visiting, brother. Let's do lots of naughty things with Kurumi today!" Her white skin and bouncy, perfectly shaped breasts are irresistible! She straddles her brother and immediately licks his erect cock. In return, he licks her pink, shaved pussy, then screws his cock into her dripping wet pussy and serves her in a cowgirl position while drooling! After eating sweets and playing games and having fun, Kurumi feeds him something by mouth... "I'll take you to Kurumi's world." When the brother wakes up, he finds Kurumi, who has turned into a succubus, the complete opposite of the innocent Kurumi from before! The brother is so excited and erect in this erotic situation that he can't contain his excitement and thrusts his cock in and out of Kurumi's pussy over and over again! Kurumi-chan is happy as her pussy juices flow, "Big brother, cum inside me!" "Next time, thrust into me from behind!" It feels so good that she shoots multiple times! Her little sister's pussy is now sticky with her big brother's sperm!
