yokubou 涩谷辣妹: Short spiral channel and contrasting contact

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.

Dimensions and shape

The sample weighed 613g, measured 13.5cm overall and had an 11cm channel. Its substantial brown body is roughly cylindrical and reasonably easy to hold. Later references to about 600g and 13cm are rounded descriptions, not replacements for the initially stated measurements.

Material was described as standard firmness without a number, with little oil or odor. A suggested similarity to 琉娜 based on color and feel does not confirm formulation. Back detail was more pronounced than the simplified entry.

Channel layout

Large spiral ridges occupy the first half, followed by shallow relief. Many visible shapes do not translate into dense fine detail. Walls appeared substantial in the cutaway, but front and rear cavity widths differed considerably. No actual damage was reported, nor was puncture resistance established.

Feedback and limitations

A small entry made alignment and initial passage difficult, requiring adequate lubrication rather than force. Beyond it, the space opened widely: enclosure became loose despite pronounced spiral scraping. Deeper contact then became ordinary and mildly textured.

The reviewer liked front scraping but found its distinct zone lasted only a few centimeters, with an inconsistent front-to-rear style. The 11cm channel was short for the reviewer's preference, and end pressure was disliked. This is a personal length preference, not a body-size suitability finding.

Rating

The source awarded 3 stars overall, without category scores. Substantial grip, low oil and odor, and front spiral relief were characteristics. Small-entry/large-cavity contrast, loose enclosure, coarse detail, a brief strong-texture zone and bland rear layout were limitations.
