Since you can't see any way to escape your fate, you concede that you might as well go along with the doctor's plans for now. Reluctantly, you spread your legs apart, giving the doctor full access to your nether regions.
"That's my good girl," the doctor says in a sympathetic voice, patting your head. "I knew you'd come around."
In the darkness, you can sense the doctor shifting so that his head is positioned between your legs. You can feel his breath flowing across your inner thighs, and despite your predicament, you are finding yourself becoming aroused at the doctor's advances. Your nipples are extending slightly, and your pussy is moistening with excitement. You feel the doctor's head approaching your slit, then cry out through your gag as his tongue finds your clit.
"Good behavior has its rewards," he states before dipping his head between your thighs again for another taste of your loins. The man is certainly no stranger to cunnilingus, you soon discover, and soon you are writhing in ecstasy from his talented tongue. Your resistance to the doctor's plans slowly melts into a blissful obedience as he continues to pleasure you, lapping up the juices flowing from deep inside you. The doctor, hearing muffled moans from behind your ball gag, doubles his efforts, driving his tongue deeper to lick the walls of your pussy. The feeling quickly becomes more than you can handle, and within moments you explode into an intense orgasm. The force of your sexual screams is almost enough to push the gag out of your mouth, though it barely holds in place. Cum pours out from your hole in spasms into the doctor's mouth, who eagerly slurps down your sweet nectar. Your climax continues for about half a minute before the flow of juices stops, and the doctor licks his lips before shifting again.
"My dear, you have such a sweet flavor," Dr. Labinnac compliments. "But enough of the appetizer. It's time for the main course!"
With you still lying on your back, the doctor climbs onto the table on top of you and positions his now stiff cock between your legs. In the darkness, you can't really tell what is happening, adding to the excitement of the situation. You wait in anticipation until at last, you feel the tip of his penis brush against your lower lips. With a slow push, he begins easing his member inside your slick pussy. Your breathing grows heavier as inch after inch of the doctor's cock slides deeper, causing the most pleasant sensations. Once his entire length is buried within you, he gradually pulls back out a bit, then thrusts back into you, building up into a slow rhythmic fuck.
You tilt your head back and moan through your gag again as the doctor continues sliding in and out. You can feel another orgasm rapidly building inside you. Eager for another explosion of pleasure, you spread your legs as wide as you can against your ankle restraints, trying to allow him better access. Sensing your desire, the doctor quickens the rhythm of his strokes. Your breasts bounce wildly as your entire body rocks back and forth with the force of his thrusts, and you're loving every minute of it. As you approach your climax, the doctor reaches his own peak, and without warning he shoves his cock inside you to the hilt. You feel him expand slightly inside your pussy, then spasm as thick jets of his cum find their way deep inside you. The feeling is incredible, and it's just enough to trigger your own orgasm. You wail through your gag as you convulse in sheer sexual bliss, the doctor's cum mixing with your own within you. It feels like a never-ending supply of cum shooting into you, but as all good things must come to an end, the doctor eventually pulls his cock out of you with a slimy popping sound. You can only lay back exhausted but content, smiling around the ball gag that still keeps you silent.
"That was quite nice, young lady," the doctor says to you. "It's a shame I can't keep you around for a good fuck every now and then, but I have such a dire need for test subjects..."
Your mind snaps back to your predicament. You're still trapped here, helpless to escape from the doctor's sadistic designs. You have no idea what's going to happen to you, but you get the feeling that you won't be leaving this building alive. Your thoughts shift to more pleasant images of your family, your friends, your life up to this point, anything that will get your mind off of this horrible situation. As you try to distract yourself, the doctor is wondering which of his experiments you should help him with.
"Hmmm..." he says to himself, just loud enough for you to make out the words. "What shall I do with her? Perhaps test out one of my new execution methods? I have a few new cooking methods I'd like to try, too." You hear him sigh loudly. "Too many good experiments, not enough test subjects..."
