House of Mating (original Japanese title: Kōshitsu no Mating or similar, from doujin circle Chinchintei) is a well-known adult doujin manga (fan-made comic) in the hentai genre, featuring themes of incest, seduction, and explicit sexual encounters in a domestic setting. The story revolves around a widowed mother who dotes excessively on her son, leading to escalating intimacy that crosses familial boundaries. It's celebrated in niche online communities for its exaggerated, "beastly" eroticism, hence the subtitle "In My House Where the Voices of Beasts Echo, I'm the Only One Who Can't Have Sex," which captures the protagonist's frustrated isolation amid the household's primal urges.

In early 2024, the manga received a live-action adaptation in the form of a Japanese Adult Video (JAV) titled NIMA-023: House of Mating Live-Action Version! In My House Where the Voices of Beasts Echo, I'm the Only One Who Can't Have Sex... Produced by Fitch studio and directed by Doragon Nishikawa, this 150-minute film faithfully recreates the manga's plot while amplifying its sensual elements through cosplay, oil massages, and dramatic role-playing.

Plot Summary (Spoiler-Light)The narrative follows Kakeru, a young man living with his voluptuous, affectionate mother, Monami, after the loss of his father. Their daily rituals of hugs and kisses evolve into a promise of forbidden passion on Kakeru's birthday. However, tension builds when an intrusive "uncle" figure enters the scene, manipulating Monami with seductive tactics like erotic massages and beast-themed lingerie. Kakeru, feeling sidelined and aroused by the "echoes of beasts" (metaphorical moans and desires filling the house), installs hidden cameras to uncover the truth—leading to revelations of creampie encounters and themes of cuckolding (NTR). The story blends emotional longing with raw, animalistic sex scenes, emphasizing the son's ultimate exclusion from the household's escalating lust.

Cast and Production Highlights

Monami Takarada stars as the seductive mother, bringing her signature "plump, big-breasted" appeal to the role. Known for her work in mature-themed JAVs, Takarada's performance is praised for its mix of nurturing warmth and feral sensuality, including tiger-print cosplay that nods to the "beast" motif.

Supporting roles include actors portraying the son and the manipulative uncle, with the production emphasizing high-quality cinematography, English subtitles in fan releases, and uncensored versions circulating online.

Released on January 2, 2024, the film collaborates with the original doujin creators, making it a direct homage rather than a loose interpretation.
