Monster girl's Gloryhole

In a distant dystopian future where monsters, aliens, and demons have overthrown most of Earth. There are monsters, aliens, and demons who have chosen to side with humanity and leave Earth to explore the cosmos. Space is now a road to various planets and galaxies, easy to navigate. Here's where you come in! You stop by an intergalactic fueling spot, and take a bathroom break. You notice a hole nonchalantly opened in the wall next to you, and you're intrigued, since you haven't seen or used a glory hole since you were last on Earth. Do you wait for someone to stick their finger in the hole to have a good time, or do you stick your finger in the hole yourself and wait for someone to come? You might find a strange shaped penis of various monsters and aliens. The different textures and shapes of mouths and butts you feel. The choice is yours~
