Is it worth investing a flat chested sex doll?

The flat chested design of the life size sex doll brings a leap in sports performance. By removing the traditional chest counterweight, engineers implanted a liquid metal balance system in the pelvic area. When the flat chested sex doll performs large movements such as yoga, the center of gravity offset error is controlled within 0.5 mm. Its improved shoulder joint structure supports 270-degree rotation and can accurately reproduce the gymnast's back flip.
