from experience with my body (lol) i was able to craft a stiff butt plug that is just a little little little longer than is physically able to fit inside, just so that an eyelet is all that is left outside. a posture bar is then hooked from a posture collar to the butt plug. the plug was crafted from an old vibrating plug that stopped working. pulled out the vibe and stuck it on a dowel.
i got a photo series of the test here: https://the.tiesthatbind.me/devices/rea ... -a-success - it shows me getting ready, inserting, and testing, but in a nice body stocking with some nipple clamps too for fun
(cb6k is on too >_>)the results were great. because of the length of the posture bar i wasn't able to "push" the plug out, nor was i able to deviate from the posture position much; any bending forward is extremely limited because the bar pulls on the plug and the plug is like all "lol, nope"
