You need her inside of you.

“Oh fuck I have to at least try it. I gain power from sex just like her there must be a way to fuck without loosing. Hmm, She drained me fucking my pussy if I grow a cock and fuck hers I know I will loose. Oh hell, anal isn't real sex right?” You climb on and slide down her cock as it impales you, “Oh wow.” Pulling your feet up you get them onto the chair so you can rise up to ride her mast. “So fucking good.” You say panting as you bounce up and down on her leaning back till your back rubs her sexy breasts. “Oh.” Her nipples even massage your back as you ride. You are pretty sure she isn't even draining you.

Her hands clasp your sexy tits and she pounds up with greater vigor. “Oh you got free.” You say panting.

“I did, and now you will die.” She pulls your head back to the side and her lips find yours. Your tongue lashes out to taste her delicious lips. The two of you lock in a twisted kiss, she pounds up with renewed vigor. Strangely something new climbs up stretching your tight pussy. “Like it, I can grow a second, just for you. The feeling is amazing, you are fucked so completely, locked in a most likely fatal embrace with a dangerous demon. “Yes feed me girl. Feed me.” She whispers softly and you don't want anything else, you want to make your lover strong.

“Oh it is So good. This is so stupid. Fuck me harder.” You command, and she does just as instructed till your legs simply give out and you are bounced off both huge cocks and flop on the floor. She rises up, towering over you, looking up you again command, “Fuck me harder.” You really aren't sure if it is your magic or just what she wants, but she is again on top of you. Her twin rods swell to even more massive proportions as she dives deep into you. “Oh my, why is it so good.” You exclaim as her body slams against yours.

“You know you aren't going to even exist when I am through with you right?” She whispers to you as she kisses and licks your cute face. She holds your wrists tightly, and puts your hands behind your head. Pumping in and out she begins filling you with cum, pulling out as she does so the last few spurts cover you. “Sorry dear, I am going to have to finish you now. I have chores to do.” She takes hold of her cocks and with a stroke they merge into a single evil looking monster. She asks, “Shall I fuck your cute little pussy, or your ass?”

“My pussy.” You answer panting, the smile of a well fucked woman on your face.

“As you wish” She lays down on top of you, takes your mouth in hers, and drives her cock up inside of you till you can see it pushing out your belly. “Don't worry, I won't forget you, so you will live on in my memory. That is something right?” She asks between grunts as she picks up the pace and begins fucking the life out of you. Every pounding thrust seems deeper and deeper, it is as if she is pounding away at your very being, and you are loving it. Her lips locked with yours you begin to feel something more, a suction that you didn't notice before. Everything that you are is flowing out of your mouth and fueling her hunger.

“Bind.” You say meekly trying to summon the magic, but nothing comes. Then something new happens, the black balls of energy, as well as the scroll, all the things you hid in the little dimensional pocket fall next to you onto the floor. It would seem the last of your magic, even the least bit is failing and fading away. Your mind and body scrambling to do anything to fight her off, yet you know she has basically won already.

Suddenly she breaks off the kiss and leans back looking down at you, her meat begins spewing another flood of cum into your body. However this time the pressure of the flood feels different, not as if it was empowering you, but more like an intrusion, an uncomfortable pressure. The pleasure of the carnal act still remains, but you don't seem to be gaining anything from it. Your head even hurts, and you think your temple is bleeding. She looks deeply into your eyes and asks, “Wait. Why aren't you dead?” Feebly you raise your hand up and push her away, to no effect. She simply grabs your wrist and asks again, “Why aren't you dead? You don't have anything left, I can feel it. I drank every last drop.” She stands up, her long cock sliding out of your cleft with an audible 'pop'. She stares down at you with intense concentration. “Wait, you have a soul. You are no demon. What are you?” Then she drops back down on you like a pouncing beast, “No matter I shall take it as well now that I know it is there.” Her lips again lock with yours. “Yes so good.” She whispers and this time it feels a bit different, you can even feel your cheeks begin to sink in as she drains the life out of you.

Your mind races with panic but your body just won't stop, you clutch her breasts, grind up with your cunt even though her cock has vanished. You still feel your body thrusting up at her as if begging to be fucked, all the while your lips are locked with hers passionately as if she was your greatest love. Your hands lash out feeling for anything. All seems lost but your hand finds the two largest of the black orbs. You have no idea what you can do with it in your weakened state, but with no other options you are able to do one last act of self preservation. You simply reach up and stick the largest one in her mouth.

She gags as it fills her mouth, then in a flash of black it bursts and the energy flows into her, “So much power.” She calls out and rises up off of you. Looking around she sees the additional two balls that sit on the floor and scrambles to get them before you do. Luckily for you she also seems to be very drunk from the power and you are able to scoop up all three. She lurches forward at you, “Give them to me. I will rip you apart.” You dive at her feet to knock her down and the impact does the job, she is sent flying forward as you roll across the room, however as you do you loose your grip on two of the balls that you had clutched in your hand, so all you have left is one. As she scrambles to get the two that have fallen free you see an opportunity.
