Wait until he leaves to try to escape.

You determine to endure until he leaves you alone again, and then you're sure to be able to escape. But before you can ponder further, he is between your legs. He is rubbing you from behind, his fingers touching your pussy through the thin fabric of your panties. "What the, huh, hell are you doing?" You squeal in a way that immediately embarrasses you. You squirm, pulling your hips away from his touch, but his hand simply follows and continues to rub.

He leans over you, pressing his muscles into your back.  You feel his hard meet pressing on your behind through his cloth.  Grimy fingers glide along your tummy.  It feels, abnormally sensual when he touches your stomach, or your hips, or your shoulders.  "Do you know what this is?"  You look under your stomach and notice that an arcane rune has been inscribed on your skin where he touches.  The mysterious glyph of arcing loops and strokes is hot pink in color and covers a stretch of your body from your belly button to your right side.  "It means you are now my ****."  He explains.

"Never!"  You try to elbow him in the face, but the chain pulls taught and prevents you from reaching far enough.  

He then unfastens your front zip sports bra to expose your chest. His hand slithers all over your tits. He grasps your left breast and starts to fondle you. His fingers dig into your skin and he works you with firm but gentle circular motions. Your nipples are hopelessly hard, from the cool cave air if not from his touch.

You find yourself panting.  "Whuh, huh, what?"  You do not want to admit how nice it feels, but it is really distracting.  Why does your skin feel so sensitive?  He rolls your nipples in his fingers and you feel jolts of electricity race through you.    

He grabs your panties and slides them down to your knees, exposing your hairless mound.  Then he starts to trace the folds of your labia directly.  His probing fingers locate your clit.  Why is your clit so hard?

"Hmmm?  You like that don't you?"  He says as he starts to rub the little nub with his forefinger.  It is, exquisite.  He makes you quiver at every touch.  "The Glyph of Firilana will make you incredibly horny."  He rubs hard.  "And especially sensitive to pleasure.  Just look how wet you're getting"  

He's right. It's crazy, but you're dripping. He pulls his hand back slowly, and you find yourself moving your hips back to follow him. You attempt to rub yourself against his hand but he pulls it out of your reach. You hear his demonic laughter. "You are a little slut aren't you?"

You know that you must get yourself under control to get out of this. You must focus.

Then his hand takes your chin and turns your face. The next thing you knew, his lips are pressed to yours and his tongue is sloshing about trying to get into your mouth. You have to concentrate to keep your teeth clenched. You look into his eyes. His deep red, intense eyes. You see yourself reflected in them. And you look like you want him. You **** yourself to close your eyes and concentrate. You hold out and he eventually gives up on the attempted french kiss. How would it taste, you wonder, if you did let him tongue kiss you?

As you catch your breath, however, you feel something poking you in the butt. It is the tip of his cock! And it is tracing its way over your ass, over your hole and down towards your pussy. Then it brushes into your pussy-lips. He slides it up and down the outside of your slit. Your pussy is so hot and tingly. It wants to be filled up. It has betrayed you. If you don't make your move now? You have to pull it together before it's too late!

"No!!!" You shout as you yank the chain with all of your might. The link is bent wide; your right arm is free! But then?

You feel him inside of you! The head of his dick has pushed its way into your pussy, and the rest of his cock is sliding in after it. "Mmmmmmmmmmmmm" You hear yourself moan loudly. It's so big! "Oh God!" He slowly pulls out, just to thrust it back into you hard. "It's awesome! Do it!" What are you saying? "No, stop!" He grips your waist and starts to rhythmically slide in and out of you. "Don't! No, don't! Stop!" It's ramming so deep inside you. It is all you could think about. "Don't stop! Don't stop!"

"Don't worry, I won't stop. Not yet."

You find yourself moving in rhythm with him. His balls smack against your ass. You're on fire. Your boobs bounce under your chest. Your free hand moves to your breast to fondle. He is such a scumbag. But you cannot resist that cock! You love the solid thunder throbbing within you; piercing you again and again. "Mmmmmmmmmm! Yeah, do it!" You can not stop moaning.

You feel him leaning over your back again so you turn your face towards him. He kissed you again, and this time he has no trouble thrusting his tongue down your throat. You let him drink you, as his cock pounds in and out. You kiss back, sucking his face, tracing his tusks and mouth with your tongue. The heat is building. You feel like you are going to overflow.

"Hea ha ha." He laughs. "You like being a slut?"

And you realized that you do. "Yes. I'm a huge slut and I love it!" You love the way it feels and you never want it to end. And you cannot hold back much longer. "I'm your slut. Now fuck me!"

And he does. Harder and faster. You get cock-blasted until you can barely stand it! And then, "YES!!! FUCK ME!!!!!" You hear your own hot screams of pleasure! He grabs your hips and holds his massive cock inside of you as waves of orgasms run through your whole body. You spasm and writhe on his rigid pole, savoring every moment. You are still gasping and panting for breath when he pulls out.

"Open wide cum bunny." He demands. His purple dick is still rock hard and he is slowly jerking it right before your eyes. He presses the tip into your lips, so you immediately push your face over it and start to suck hard. You trace its contours with your tongue. He starts moaning, and he works the base of his shaft faster and faster. You slide forward and back on his cock, and he fucks your face in rhythm to your sucking. He places a hand on your head, messing with your hair and pulling you over him. You are loving the way the huge filthy dick slides over your tongue. You pull off to swirl your tongue around the tip. It tastes so, naughty. Then you swallow it back and try to take it as deep down your throat as possible. He is moaning so loud. And then he is grunting, and bucking his cock hard into your face. And, then you taste hot bitter slime erupting in your mouth. You try to swallow, letting the viscous fluid trickle down your throat. Burst after burst, he fills up your mouth with his jizz until you are overflowing. He pulls out and you proudly let the cum pour over your chin with a smile. Then you feel his shaft slapping you on the forehead.

"Bad cum bunny." He scolds. "Now, swallow every bit."

So you lick your lips and guzzle it all down. You start to rub your beaming face into his dick. Feeling it press against your cheeks, and chin, and forehead, and eyes, and lips. And you concede that you no longer wish to escape. You want nothing but to be his cum-bunny.
