Returning home after years, I found my sister still lazy and not working, but her big ass was incredibly sexy! Witnessing her masturbating by accident pushed me over the edge, leading to raw ass-groping and creampie sex. During my stay, whenever I felt urges, we had immediate sex! Sneaking in the hallway, rubbing my dick against her fleshy butt and ejaculating, her saying 'No' while orgasming from her brother's cock was the best. I made my shut-in sister, who had no sexual experience, climax wildly!

Ayaka Yamagishi's portrayal of a lazy but highly sexual shut-in sister is ideal. Although she resists at first, her erotic fascination with her brother's dick is irresistible. The careless masturbation scene embodies AV fantasy. Yamagishi's big ass is artistic and excites viewers, but the male actor's expressionless performance sometimes breaks immersion, slightly diminishing the erotic atmosphere. Overall, it's a must-watch for excitement!
