You watch horrified as the dildo twists around, and begins to slice back towards you like a large inchworm. You lick your lips in fear, as you back slowly away, and you barely notice that your lips feel funny as you do. You slip back into your room, but it is keeping up with you, maybe even catching up.
Only when your legs bump up against your bed, and you fall over onto it do you finally loose the last of your compose and begin to panic. You flip over, as your stomach gurgles loudly, and grab the part of your bed which is nearest the wall. You begin to pull yourself across, as you kick your legs widly. Unfortuneatly, for you, you feel something land on your back. Something warm, and wet slips past the waistband of your shorts and underwear, and they slip down just before the dildo penetrates your ass.
You groan, "Nooooo!", but like before it begins to slip in and out under its own power. Your attempts to pull it back out are in vain, and suddenly it shoots a large load up your ass. It then drops out, and lays on the top of the bed unmoving. You quickly kick it off, onto the floor, and rush over into the bathroom. There your try vainly to void yourself, only to find yourself unable to. Your gag reflex seems to be supressed, or gone, and no matter how hard you push, your ass remains fully loaded.
