The glass dildo is made of high temperature-resistant glass. So it’s very hygienic and safe. You can heat it in boiling water and insert it into the vagina or anus. That feeling is warm sex. It can also be cooled in ice water, and the feeling will be the opposite. And the surface of the glass dildo is very smooth. You can enter any hole without too much effort. And glass dildo is equally as hard like an erection man constantly stimulating honey beans.
