I enjoy letting insects crawl into my ass. Its like inserting a living vibrator that will wriggle around your sphincter into places that you didn’t even realise exist. Of course, all forms of insectoids are accepted. But i generally use millipedes and earthworms, because they’re longer and have a tendency to crawl in deep, sometimes i even use centipedes if i want a more ticklish feeling. Understandably they’re hesitant at first, so i shove some soil into my anus to make it look like a nice dirt hole for them to burrow into. It’s really important for you to be gentle at all times, these small creatures can be skittish. For more advanced and adventurous fellows, try inserting a flying insect into your butt. To describe the way it buzzes around inside you, it’s like having butterflies in your stomach, but they’re in your large intestines and anal regions instead and you are having a mind blowingly good orgasm. My favorite flying insect/sex toy would be a wasp, just the right size to shove into my ass and the stinger doesn’t come off unlike bees. Plus, if you have machoistic tendencies i highly recommend inserting more than one.
*Important Note! Remember to shit before playtime, and use an enema or a suppository of some sort to clean out the faeces. Certain insects may get trapped halfway in and it’ll be unpleasant for both you and your guest!*
