Fisting Yourself

You slide off the cock ring, and stretch it out over your wrist, watching your hand appear on the wall. You grin even wider at the posibilities that this opens. You suck on your fingers for a few seconds to lube them up, then turn around. You shudder in anticipation, and stick your middle finger up your ass. You start to thrust it in and out, curling and flexing it to loosen up your asshole. After a bit, you slide in a second finger, and start scissoring them to loosen you even further. You slide in a third and fourth at once the same way, your thumb the only part of your hand not in you. You spread your fingers, and slip your thumb in. You bite your lip, and ball up your fist, moaning loudly as it expands.
