The insert weighs 787g, measures 17cm overall and has an internal length of 14.5cm, with its weight concentrated toward the rear. The review assigns hardness grade 0. Oil release and odor are low; the uncolored surface and entrance are simply detailed. Its exterior resembles 柔情猫娘, with a different opening.

The straight channel uses longitudinal ridges parallel to movement, producing compression rather than substantial scraping. Four lengthwise columns follow the first narrowing ring; small granules contribute little, and a further narrowing finishes the channel. Compared with 汤马 奴隶契约, these ridges lack curvature. The overall concept also resembles 柔情猫娘一代.

Air removal produces pronounced enclosure, clamping and pressure. However, the middle section lacks variation, successive constrictions do not build distinct stages, and the finish is unremarkable. The source proposes firmer material as a possible improvement, not an existing feature.

The original rating is 3 stars: no major fault and effective tight compression, but limited structural refinement and variety.
