Flexible bed for controlled practice with sexual activity, has trapezoidal parallelogram, anchored in both ends at base of blade, which allow to fit voluntarily distance between shovels

摘要

The flexible bed has a trapezoidal parallelogram, anchored in both ends at the base of the blade, which allow fitting voluntarily distance between shovels. The shovel has two laminated steel plates joined behind a crown shape support to an obtuse angle with the shovel. An acute angle is formed, which is extended to provide a base until anchoring with the trapezoidal parallelogram is carried out.
