In 2023, Aya Shiomi entered her second year as an exclusive Dogma actress. Privately having lesbian experiences and having been fist-fucked numerous times by Yui Misaki, she held untapped potential as a dominant fister. Before her stood the perfect lesbian partner—Uni Shiokawa. Just one year after her debut, Uni found immense pleasure in appearing in extreme, hardcore videos and deeply admired Aya as the ultimate female masochist. She was chosen as the one to undergo this fisting initiation. Aya insisted on training in her own style, not imitating Yui Misaki. As filming began, all hesitation vanished instantly. Shiomin, as she's affectionately called, delivered confident, masterful lesbian domination that brought out Uni's submissive nature like a natural. Aya told her, "It'd be great if you could take my fist and wrist in the first scene, but don't push yourself." Yet, in a seamless progression, Uni swallowed Shiomin's entire fist and wrist, initially crying out, "It's so tight, so full!" But soon, she began to feel pleasure and suddenly climaxed violently from fisting in the very first scene. Shiomin's dominant demeanor was unbelievably commanding for a first-time top, and in that moment, I knew—this pairing would create the ultimate lesbian fisting masterpiece. This release has become an unforgettable work for me.
