Might want to put some kind of round little knob on the end, they are usually squared off. If you are just going up inside your ass-cunt, maybe not. But any farther and it will need a little more of a gentle end to it.
Thanks. I'm thinking about getting one of those video bore scopes. They can reach at least the transverse colon. Even be useful as an actual bore scope, after washing off the anal mucus.
That is a spice bottle with the bottom cut out and the edges smoothed over so it doesn't cut at the inside of my ass-cunt. I'm not afraid of it bleeding, sometimes a lot, but not that much.
