Ahahahaha! Uh, I hadn’t thought of that myself, but honestly if anyone wants to imagine my designs with things like that then PLEASE BY ALL MEANS GO RIGHT AHEAD. 8D
Technically I have multiple versions of my Cardassian design since sometimes I want them with venom (because omgz so cool and dangerous and stuff), and sometimes I don’t (because oh god the daily hassle Bashir and Garak would have to go through just to make sure there was no danger of casually poisoning Bashir - the best solution I’ve thought up is Bashir developing an anti-venom, but considering Garak’s history/culture, I think allowing another species to develop an anti-venom to your venom is probably like the biggest cultural NO you could ever do as a Cardassian), and sometimes I want snake-style hemipenes, and sometimes I want a single prehensile dolphin-style ding-dong.
…Depending on what stupid goofy all-my-birthdays-happened-at-once expression I want to imagine Bashir pulling when he sees whatever Garak’s got between his legs.
SO VERSIONS WITH AND WITHOUT AUTOMATIC BONDAGE ARE AWESOME TOO.
(I think that holding their snouts might serve a similar purpose, because they’re so sensitive. I don’t think it would immobilise them, but they’d probably become very very still and only make minute safe movements to try and free their snouts since they’ve stopped being able to sense enough about their surroundings to know whether it’s ok to thrash all their limbs around. That’s why the whole bridle/muzzle thing would be SUPER INTENSE BONDAGE.)
