You refuse to give in to sanity.

“Don't care.” Is all you say, taking the shaft in both hands, you set to slobbering all over the tip. “Guess I won't be giving you head though.” You say with a little giggle. “Or can I?” You conjure the image of your mouth a bit wider, and while it doesn't exactly grow, your jaw almost seems to unhinge like a snake, and to the surprise of both of you, the head of his cock pops into your mouth. He reaches up and claws the ceiling as you get it in, not wanting to damage you, content to let you work. You try your best to get your body to let him deep throat you, but it doesn't happen, your neck just won't give, you do succeed in getting his mast rock hard. Once you do you turn around, get on your hands and knees, and look back, “Just stuff it in, I'll make it work.” He seems legitimately concerned for your well being, but all the same, you did suck his cock, and he is a monster after all. He can't resist such a request.

“I have to confess, I have always wanted to ravage a erinys. Oh well, if you survive this, it will be a great story.” Letting out a little chuckle that reminds you how truly evil a creature he most likely is, he then pushes his cock at the entrance of your asshole.

“Anal, really?” You ask, but the tips of his claws are already pulling apart your anus in an attempt to get it wide enough to get even the tip of his cock inside of you. You concentrate all you can on going slack, relaxing your muscles, and even somehow reforming your body to allow the intrusion. You don't know if it is by magic, might, or sheer determination, but suddenly you let out a gasp as your body tells you that the head has slipped in. “Oh, it is so big.” He bares down on you, and you push back into him, and time seems to stop as he slides deeper and deeper into you. You can actually feel his cock within you against your spine as it moves up your body. Similarly looking down across your belly you can actually see the bulge where his cock is. It seems to stop just short of puncturing your diaphragm, but makes it so you can't take a breath. His massive balls press against your legs, and impossibly you know his entire 20” length is up your ass. “Told ya.” You gasp, and he pulls back. Air fills your lungs, and your insides seem to collapse in on the furrow that he just carved into you. But this respite is very short lived, as no sooner does he pull out till only the tip remains in place, he dives back in. For the next moments it is almost like he is breathing for you as with each thrust your lungs fill and empty. He may have entered the ass, but it seems he is fucking your entire existence through that now gaping hole. As before, it doesn't take long before the strength you lost seems to flood back into you. The fucking is amazing, waves after waves of ecstasy flow through your body as orgasm after orgasm rocks your slender frame. You are able to work in a single finger into your pussy, and work your clit with a fervor as well. His fingers tease your breasts as he grips your entire torso with his powerful right hand, grabs your leg and arm with the other massive hand, and hoists you off of the ground. Rocking back on his heels he finds the chair and sits down. In an instant you have become little more than a masturbation aid, as he holds you in both hands and slams you down onto his cock over and over again. Anyone looking on might even miss that he was holding a person, and not simply jacking his rod. Looks aside, you care little, the waves of pleasure that rock your body to the core are all that matter. The power in him is impossible to ignore, and you definitely are drawing strength from it. The longer he fucks you, the better you feel and the easier it is to breathe and pleasure yourself as well. He has your left arm and hand firmly clasped, but that doesn't stop you from using your right to work your cunt in a frenzy. More than an hour later you begin to notice he is grunting loudly. Another hour and his pace slows slightly. A third hour and you are sure you can hear his heart beating, or is it yours? The fourth and fifth hour pass, still railing your body, his grip shifts several times, but still the same. As the sixth hour rolls in, he finally lets go of you, try as you might, you just can't get much leverage to get your legs under you so it is more of a brief rest, still impaled of course, before he once again grips you and continues fucking.

Finally as hour seven enters, he pulls you off of his shaft, tosses you to the floor, and slumps back in the chair, sliding onto the floor, and lying on his back, chest heaving. “I can do no more.” he says gasping, and you instantly feel like you have failed as he is not only still hard, but he hasn't cum a drop.

“No, let me do this. I know I can.” You say rising on wobbling legs. Crawling over to him you roll him on his side and lick and suck at the shaft. His fucking has returned much of your strength and once again you try to use your ability, and unhinge your jaw. The head of his member slips into your mouth. Then you simply push. He is so big he isn't moving anywhere, so it is as if pushing against a wall, but push you do. Your bones resist the intrusion, but you are defiant. You are the master here, and you will get it in. Gulping and pushing you drive forward trying to engulf his cock, when suddenly something impossible happens. Your face smacks against his sack. His cock is buried within your throat. Your neck looks ready to burst, but it feels so weird. Then using your hands you kneed and stroke his sack, even slipping a fist into his massive anus as you move forward and back as fast as you can while working his sack stroking him. The effect is not instant, but it is big. He slams the ground with a powerful fist, he lets out a howl. His body finally shudders and with a spurt he lets loose a blast of cum that fills your stomach. A second spasm fills you to the point you feel like you are in danger of rupture. A third spasm and you are quickly pulling back to dislodge his cock from your mouth. The fourth spasm blasts you in the face like a fire hose, and the fifth and final covers you from head to toe in sticky milky cum. Finally after blasting what must be a century worth of buildup, his eyes close, and you hear snoring rumbling from the great beast. For a while you simply lie there, hand on your stomach that you are sure looks like you are with child. Then when it becomes obvious you aren't vomiting any of it up any time soon you call forth the magic you were taught by the demon, and perform the ritual. The black stone is so large you can't get it out, and in a panic, you decide the only option is to cut it out. Pulling out the dagger, you find the lump in your belly, and steel your nerves to make the incision. But it doesn't prove necessary, as the massive rock inside of you is in for too long, and the magic is released into you. The effect is instant and amazing. You are completely revitalized, every ache, bruise, and mark on you is healed, and your body seems to crackle with energy. The effect only lasts a couple of seconds, but as it subsides you are sure that something is new. Concentrating on the “new” feeling you realize you have learned something from your massive new friend. In absorbing the stone you feel like you can sift knowledge in his mind, yet it is slipping fast, quickly you try to find something to hold onto, and you do, “Reveal.” As you say the spell you are laid low. The magic is in your mind, and now within your power, but the cost you now know is great, using it will drain most if not all of your magic reserve, but as you do for a couple of seconds you are able to look around the room and “know things.” Your demoness captive is indeed named Asrashia. Your new friend is named Bulrothus. And the weapons you took are crafted of abyssal silver and can harm any devil or angel, as well as any other beast harmed by silver like many undead and lycanthropes. The last of these, you didn't really know existed before the knowledge of the weapons presented itself. That said you also know if enchanted they can amplify the magic used and become truly fearsome weapons. With that your new energy drained by the casting, you are content to slide over to the bed and pull a soft silk cover over you and drift asleep. Finally feeling a bit safe for the first time.
