So, lets say this is sexually stimulating to do, how does this play out in practice ? Are you masturbating while doing it ? Seems to be a rather short stimulation at best. Are you constantly restuffing yourself ? Isn't that too much of a hassle and i imagine rather disrupting to the whole wank experience ? To be honest, that looks more like a two person job. One masturbating and squeezing out the slime, the other reloading every so often. You'd probably have to pay someone to do that for you. Seems like a rather big ask to spring on someone, unless they share this specific fetish. You could probably up the volume so the stimulation lasts longer. Maybe a medical professional can chime in with what volume of liquid/slime is safe to shoot up your butt. And is this cornstarch slime is compatible with your run of the mill enema equipment ? But if you want more volume, you might need to look into more industrial equipment. Then again, the larger you go, the more of a pain in the ass is the handling going to be all by yourself. And then we are back at the need of additional personal. And i wonder if you go with room temperature or heat it up close to body temperature.
