1. 【Golden Ratio Buttock Contour Replication System】
3D-modeled from North American female ergonomic data, it reproduces 1:1 the plump lift and muscle distribution of a peach-shaped buttock—the natural arc of the gluteus maximus, the subtle convex texture of the gluteus medius, and the smooth concave curve of the gluteal cleft. Paired with medical-grade liquid silicone elastic support, deep muscle layers rebound in tandem when pressed, delivering a bouncy grip identical to real buttocks.
2. 【Silk-Satin Skin Bionic Craft】
The simulated buttock skin is constructed with 7-layer composite material: a 0.05mm ultra-thin matte film on the surface mimics delicate pores, a thermo-conductive core in the middle locks in 37℃ constant temperature, and a memory foam skeleton at the base restores muscle softness. The silky touch and subtle damping from skin texture, combined with the natural buttock curvature’s ergonomic fit, infuse every contact with warm, lifelike vitality.
3. 【Bionic Passage Dynamic Structure】
The inner wall features spiral folds and a granular matrix designed from female physiological data: a sphincter-like structure at the entrance tightens dynamically, mid-section raised nodes distributed in golden ratio stimulate sensitive areas, and a dome-shaped cavity at the end creates enveloping negative pressure. Paired with 0.3-second elastic contraction feedback, it crafts a progressive sensory experience from gentle touch to deep immersion.
4. 【Ergonomic Support Tilt Design】
A 28° golden support tilt in the buttocks adapts to multiple positions: stable center of gravity when standing, natural gluteal cleft alignment with human curves when lying down. Combined with anti-slip hip textures and palm-conforming recesses, it ensures comfortable, non-slip grip for single/double-hand use, maintaining precise control even during extended sessions.
5. 【Intelligent Thermal Lock Technology】
Nanoscale thermal-conductive fibers heat up to the ideal human temperature of 36.8℃ ±0.2℃ in 2 minutes, with a hollow cavity structure for heat circulation and retention—warm like real skin in winter, naturally non-sticky in summer. It eliminates immersion-breaking temperature gaps, maintaining an intimately synchronized warm experience.
6. 【Silent Vibration-Damping Structure】
The cavity is wrapped in multi-layer silicone core, with inner sound-absorbing cotton to dampen high-frequency friction noise and an outer matte surface to scatter low-frequency vibrations. Operational noise is controlled below 40 decibels, ensuring privacy in shared spaces and undisturbed focus on the immersive experience.
