## Summary

> Thick shifting folds squeeze from every direction—slow thrusts tease, fast thrusts explode.

## Description

> PRODUCT FEATURES
> 
> ✅ Dynamic tri-fold structure grips from all directions for shifting stimulation ✅ 580g thick body delivers strong wrapping pressure and soft elasticity ✅ Grip pressure changes the fold pattern for slow-wave massage or high-speed friction
> 
> PRODUCT DESCRIPTION
> 
> Designed around a “riding-position expert senpai” fantasy, this structure focuses on dynamic movement, soft pressure, and fold deformation. The interior uses a thick, multi-layered set of triangular folds that tighten from above, below, and both sides—creating a unique sensation that changes depending on thrust speed and grip.
> 
> Slow insertions activate wave-like movement: the folds undulate gently, brushing and massaging the entire shaft with a plush, warm pressure. Faster strokes transform the channel into a higher-friction horizontal groove that produces an intense, stroking resistance. The flexible hard-skin material delivers elasticity, bounce, and a satisfying firmness when squeezed.
> 
> The 580g body adds stability and weight, helping the channel maintain suction and rhythm during deep strokes. Whether you prefer slow grinding or fast pounding, the dual-mode response makes this structure highly versatile and especially rewarding for users who enjoy varied sensations in one toy.
> 
> USAGE RECOMMENDATIONS
> 
> Use thin or medium water-based lubricant to allow the folds to move freely. Adjust grip strength to experience different fold patterns—loose grip for wave-like motion, tight grip for strong compression. Avoid turning the product inside out during cleaning; rinse gently and dry thoroughly with dedicated drying sticks.
