H na Gishi Series The Animation – Episode 1 (RAW)

When his father remarries, the protagonist suddenly gains a new stepsister the same age as him. To his shock, she's the girl every guy in class fantasizes about – the shortest student in school with the most massive breasts, often serving as their secret masturbation fantasy. But this busty beauty holds a twisted belief: it's an older sister's natural duty to take care of her little brother's sexual urges. From the moment they start living together, she relentlessly pursues him – sneaking into his space, pressing her huge tits against him, offering handjobs, footjobs, blowjobs, and more at every opportunity. Convinced that draining his desires is her role, she pushes boundaries without shame, leading to intense, forbidden encounters that shatter normal family norms.

This uncensored hentai adaptation explodes with erotic tension, x-ray views, ahegao expressions, and passionate sex scenes as the protagonist grapples with overwhelming pleasure from his overly affectionate, hyper-sexual stepsister.
