[Chinese]CESD-483 The younger sister who tempts me, my girlfriend's little sister

Every time I buy new clothes or items, they always get taken by my selfish sister Ruka. Even so, I was happy because I had a passionate boyfriend who showered me with love through intense sex. However, Ruka, who wants everything that belongs to her sister, seduces and forcefully French-kisses my boyfriend while I'm sleeping next to him. She teases the glans, sucks on the testicles, and rides him cowgirl style for a stealing sex act! I don't want my beloved boyfriend to be taken by my sister, so we hug each other tightly, engaging in deep tongue-locking love sex with raw penetration and internal ejaculation to deepen our bond!
