yokubou 情热应援团2: dual channels and revised body geometry

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 sample weighed 2.75kg, with a 13cm front channel and a 12.5cm rear channel. Material felt similar to the first version, slightly softer than relative grade 0 but still with limited stretch. The surface was dry, with little noticeable oil release or odor. These are sample observations and comparative impressions, not standardized material specifications.

The second version replaces the first model's flat, widely spread form with mildly separated legs. Body proportions and entry angles were more coordinated. Pronounced exterior skin texture was removed in favor of a smooth, simple surface, reducing the distracting feel of the earlier texture when holding it. There is no coloring or elaborate exterior detail.

The front channel combines defined resistance openings with a terminal chamber, considered more practical than the earlier flat base and scattered small blocks. The rear channel is tight, with only a few small elements that were difficult to identify individually in use. Both channels sit relatively low. Rear-channel contact was slightly weaker along the back and end, but the test did not describe pronounced pressure against the outer wall, only a subtle difference.

Added resistance openings and small nodules produced more even contact. With lubrication, the direct dry friction of the earlier version was less common. Revised geometry and angles also improved handling. The channel arrangement remains conventional, without a clearly new contact mechanism.

The overall recommendation for this version was 4 stars, without category scores. The cited 3-star rating belongs to the first version and is only a comparison. Basic construction and handling improved, but stretch, some rear-channel coverage and design distinctiveness remain limited. The source's subjective reassurance is not treated as a safety or comfort guarantee.
