Silicone ballstretcher OXBALLS


The Ballstretcher Ultracore System from Oxballs is amazing! It consists of a silicone ballstretcher on which you slide the Axis silicone cockring to obtain more compression. You get a MAX BAG SQUEEZING.

How to wear this Ultracore System ?

A little lube or spit, stretch the CORE, slip your balls into the ballstretcher and adjust it. If you want maximum compression effect, slide the AXIS stretch ring over the central part of the Balls-Stretcher Core.
