Ballstretcher Half Guard Transparent

The Half Guard Clear is a transparent silicone ballstretcher from the brand Sport Fucker, straight from California.
The particularity of this element is that it serves as a cockring, thus placing itself at the base of the penis, but also under the testicles, separating them in two.

This gives you twice the sensations for sensitive testicles people. And yes it's erogenous too.
