Securing underwear in place ideas?

[pilik]

[SCAT WARNING] I'll be going through the following scenario with my normal dom when I next go away with work for the day and evening.

Before jumping on the long train journey I'll get locked up in chastity, I'll send the combo lock release code over to my dom and set an auto release for the following morning ( for safety reasons but I'd rather not wait that long...) I'll then secure my underwear in place with another lock, allowing me to still piss but not shit throughout the day. After an uncomfortable day of essentially being wedgied at work I'll enjoy a curry and beer before heading back to the hotel. I'll attempt to secure the toilet seat down in the room and then my fate is with the dom. We'll likely play a game of something (online) with the forfeit being the whole lot is being eaten.... Chastity throughout the day and during the task is going to make things "less fun" but the goal isn't to have fun, it's to be punished, which I'm sure I will be.

Feel free to suggest any additions but what I'm struggling with is coming up with something discreet that I can wear under my jeans that will keep my underwear on - to stop me from shitting throughout the day but still allow me to piss. I'm going to try something like this over my underwear but I feel like I'll still be able to pull them to one side to shit if I really tried..... I want the only other outcome to be shitting myself if I can't hold.

I reckon it's still quite easy to pull down!
