WAAA-476 Overview and Core Premise
WAAA-476 is a 2025 WANZ production starring the voluptuous Ai Sayama in a high-intensity sister-in-law NTR story.

The film runs approximately 120 minutes and focuses on relentless doggy-style pounding that leaves her trembling and squirting.
Why the Concept Hits Hard

Her natural performance makes every climax and squirt feel authentic.
Exploring the Sister-in-Law NTR Theme
The core of WAAA-476 sister-in-law NTR is the forbidden domestic relationship. Living under the same roof removes all barriers.
