Glass ass plug
From Voyeurweb's Wiki about Sex
A Glass ass plug is insertable anal plug made of glass or acryl. Glass anal plugs come in all sizes and do not vibrate. Like every other anal plug, glass ass plugs are inserted into her anus. The major two benefits of using glass or acrylic material for ass plugs are:
- Hygenic reasons: A glass ass plug can be sterilized easily in a dish washer after usage.
- Transparency: You can look "inside her anus" and see the pink skin.
