GOSE 美臀殿堂: four-channel review

Images were selected by position and quality; individual human review is pending.

This text passed automated basic checks only; it has not undergone model or human review.

The support body weighs about 6.7kg, each insert 550g, and the assembled unit about 7.3kg. Body and three inserts use grade 0 material on the review's scale, with modest oil release. Inserts share an exterior and approximately 14cm internal length; texture identifies each. Rounded contours have extensive skin detail, without obvious surface damage on the sample. The large insert fits less seamlessly than YUU幻雪机娘臀, mainly affecting appearance. Removal simplifies cleaning. Handheld use feels looser centrally; mounting improves enclosure. The fourth, built-in channel requires washing the entire body.

Insert 1: layered sheets — 2 stars

Large sheets throughout and a terminal constriction resemble a firmer version of the 魔眼 white insert. Motion produces strong friction, particularly at speed. The reviewer finds it too intense with weak enclosure, though mounting improves it.

Insert 2: fine projections — 4 stars

Small tips on complex texture resemble 汤马天音, giving fine friction at medium intensity. Mounting improves fit but reduces some detail through compression. The source's desensitization claim lacks medical support; persistent itching should not be treated as something to force through.

Insert 3: slow-use reliefs — 4 stars

Similar to 魔法星使's rear and 前辈另一面, lengthwise reliefs offer low resistance and gentle pressure. Comfortable but limited in variation and intensity.

Built-in rear channel — 4 stars

Large twisted ridges are relatively smooth, simple yet distinct. Maintenance is less convenient than with removable inserts.

The source ranks intensity 1 > 2 > built-in rear > 3. Ratings apply separately, not as a single machine score.
