RQS 约束快感 generation 4: a narrow straight channel and even soft-material pressure

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.

Specifications and material

The body weighs 856 g, measures 17 cm overall and has a 13 cm interior. It uses a simplified torso exterior and a thick book-style cardboard box. Comparative firmness is -1, with a mild milky scent. Deformation and surrounding contact were praised, although oil seepage was somewhat higher. No composition, standard hardness test or service-life test is provided.

The upper section is disproportionately large and entrance detail sparse, but the reviewer did not find a major effect on surrounding contact. Even the narrowed waist retains sufficient thickness to support the channel. This sample observation is not proof that all batches lack thin-wall issues.

Channel and comparison

The narrow straight channel includes basic suction-cup-like detail and a small end cavity. The reviewer did not actually access that cavity, so it is not a separately experienced zone. Most comfort comes from even material pressure rather than complex texture.

The source describes material and basic structure as similar to 唤起柔情猫娘 generation one. That comparison model had a more upward entrance and off-axis channel, causing end-wall pressure and uneven contact. This sample was symmetrical, with more even pressure around the channel and no similar alignment issue. Comparison-image captions say 约束快感 generation 3, inconsistent with the article's generation-4 title; those captions do not establish that the reviewed sample is generation three.

Assessment

This model receives 4 stars; the compared 柔情猫娘 generation one received 3. Stable symmetry and even soft-material pressure are strengths. Oil seepage and limited texture variation are compromises. No separate stimulation, cleaning or durability ratings are supplied, and neat moulding is not a risk-free guarantee.
