Day-Use Butt Plug & Twerk 💛 while I haven't had a lot in my ass yet, this is my favorite training plug because it is so squishy and forgiving, I could keep it in all day (and I have). Even though it's small, my lil butt is so out of practice I really have to really take my time, oil myself up and stretch it to get the plug to pop in. I celebrate with a victory twerk.
