Desc: Erotica Sex Story: A professor invites a mature woman to deliver a lesson on the awesome power of feminine submission to a classroom of college men.

I call you and ask you to meet me at my office at the University. You have a favor you owe me, and I intend to collect. You are required to appear at 2:30 pm. You should have your hair done, your nails done and feet freshly pedicured, and your pubic hair trimmed, but absolutely not shaven clean.

You know I don't like shaven pussy and you don't want me to turn you away without giving you the chance to work off your debt, do you?

You should not wear any deodorant or perfume. Your natural scent is what I need to smell.

ther than that you have flexibility in how you dress and how you present yourself. You may choose to shave you legs and armpits, or not. I find both equally sensual, so whatever makes you comfortable is more erotic for me.

Dress provocatively, but not in a brazen way. Wear either pantyhose or stockings. Do not under any circumstances wear pants. You must wear either a skirt or a dress. You choice of underwear ... whether to wear it or not, and what to wear if you do, is up to you. Whatever you do, do not masturbate to orgasm or have any sex for two days prior to arrival. You may play with yourself, but you may not climax. You may give your husband oral sex, but you may not climax.

Bring a small overnight bag with the following things: a casual change of clothes and shoes, and a masquerade mask of some sort that can partially obscure your identity, but still allow your beautiful brown eyes to be seen.

You arrive at my office promptly ten minutes before the required time.

"Where is Dr. Adam's Office?" you ask my division secretary.

She admires you for a moment, then responds, "You must be Ms. Silvia." You nod. "He asked if you could stay here in the lobby until he is ready?"

You take a seat and wait. Our appointed time comes and goes. Professors and students walk by and all admire you, discretely. Ten minutes after we are supposed to meet the secretary asks you to go down the hall to my office.

I open the door. I am dressed in a light grey business suit, blue shirt and tie. The blue of the shirt seems to accentuate the blue in my eyes.

Without a word I take your hand and usher you into my office, shutting the heavy door behind you and drawing the blinds. Sensual music plays in the background. The office is dimly lit by an ornate desk lamp, filled with books, diplomas and a few subtly sensual paintings.

Once we are isolated from the outside world I quickly press you up against the wall, my left hand entwined in your hair, my right at your waist, searching for the tie to your sexy dress. I press my lips against your neck, right below your ear, breathing in your natural scent, then begin to softly nibble ... then more lustily, more forcefully I start to ravage your neck, ears, chin, cheeks and finally your lips with my mouth.

You begin to moan and I abruptly stop and take half a step back. "Shh!" I admonish you sternly. "No words, no noise!" You lean toward me to continue the too brief kiss, but I press you back against the wall.

"Hands above your head." I whisper my command and you promptly obey, assuming the position of a dungeon prisoner, hands bound together as though caught in invisible chains. I admire you in this position. "Good, very good, Silvia. You'll do well. I knew you would."

I step back again to appraise your beauty. I'm captivated, enthralled, but I cannot show it. I must maintain my commanding demeanor.

Still holding the tie of your dress, I slowly pull the cord until the knot is undone. The dress unwraps, but in this position does not open, only exposing a narrow strip of golden flesh from your neck, down your cleavage to your kissable middle, to the lace of your black panties, naked thighs and stocking tops. It's hard not to gasp in admiration, but I maintain my stern demeanor.

I step back again. The motion sets my erection loose from the trapped position against my leg and forms an obvious tent pointed directly at you. The movement catches your eye and you glance down, allowing yourself a subtle wicked smile of acknowledgment.

"Lower your arms and take off your dress. Hang it there on the coat rack. Turn around, bend over and put your hands against the wall, with your legs spread shoulder width. Close your eyes." You follow my commands gracefully, without a word of resistance or question.

As I admire your glorious ass accentuated by the sheer lace panel of the panties, I can't help but think how I just want to drop the role play and just fuck you right now. But the game must go on.

"Lower, bend lower," I instruct and you comply. I sit in my leather desk chair and my face is level with your perfect bottom. I roll over closer to you to perform my inspection, and see your juices moistening the panel of your panties. The scent of your pussy is intoxicating.

Slowly I lower your panties and leave them at the top of your stockings. With your legs spread they won't drop farther. I spread your cheeks with my left hand and bring my right index finger to your mouth. "Suck it."

The work you do with your lips and tongue on my finger almost makes me cum, but I pull it out of your warm mouth before you can accomplish that feat. I take my finger and trail it gently across your flowering lower lips, not really touching, just grazing, upward until I reach the forbidden rear entrance. After a quick lick at your puckered hole--a lick that's really more for my own pleasure than yours--I press my moistened digit oh so gently into your ass. You can't help but gasp.

My finger still inside your tight rear entrance, I rise to my feet and unzip my fly. I take out my throbbing cock and place it right at the opening of your sopping pussy.

I press the shiny-hard helmet of my throbbing cock against your entrance. I pause, rubbing the tip up and down, parting your lips, covering myself in your flowing juices. I press the end against your clit, and grind it against you, then slowly slide up again, parting your labia, starting to open your flower with my heat. I tease you, inserting just the very end into your warm wetness. You start to moan. You try to push back into me to envelop me, but I withdraw, still teasing, not letting you yet possess the full length you so richly deserve.

Instead I hold my shaft upright against your sopping cunny and press hard, sliding my finger deeper into your ass at the same time. Your wet folds try to envelop me, from the base of my hard weapon jammed against your clit to the mouth of your womanhood near the tip. You sob quietly in frustration ... so close to your desire, but so maddeningly far. You can't see how hard I am biting my lip, making myself remain stoic when all I really want to do is fill your glorious warmth with my aching cock, then with my spurting seed.

But my desire to fill you is not as deep as the desire to overwhelm you. I step back, keeping my finger buried deep in your sweet round ass, but breaking contact between your dripping magnificence and my throbbing hardness.

You are still bent over, hands against the wall, as I remove my finger agonizingly slowly and move toward your face. Obediently, you still have your eyes closed, so it takes you by surprise as I roughly thrust my hand into the cup of your bra, quickly locate your long, hard nipple between my thumb and forefinger and squeeze hard. The brief shock of pain in your nipple rolls through the rest of your body as a flush of hot pleasure. I guide the tip of my cock under your outstretched arms toward your face. I'm sure that you can feel my heat and smell your own powerful desire that slickens my shaft.

My left hand strokes your cheek tenderly. Then again by surprise, I roughly grab a handful of your beautiful brown locks and turn your face toward me. Your gasp of surprise parts your lips and, pulling hard on your nipple to guide you, I force my cock quickly past your lips and thrust it to the back of your throat.

"Suck it clean," I hiss. With one hand in your hair and the other clamped on your nipple I pull you back and forth on my shaft as you compliantly wash your sensual nectar from my cock with your talented lips and tongue.

I want so much to bathe the back of your throat with my gushing, pent-up desire, but I do not. There is much left to do, and you seem too close to orgasm yourself. I withdraw, leaving both of us panting with unquenched need, and carefully zip my still-hard rod back into my slacks. Again standing behind you I require you to close your legs, still bent with your hands against the wall. As you comply I push your panties down to your ankles and make you step out of them.

The sight of your perfect naked backside presented to me this way atop shapely stocking covered legs and sexy sling back heels is almost too much to bear. I nearly discard all my carefully made plans to kneel down behind you and thrust my tongue into your tight rear hole until you crash in a screaming anal orgasm. Nearly. But I bite my lip again and somehow resist.

"Stand up," I command and you smartly obey. "Next to your dress on the coat rack is a lab coat. Put it on, button it." You follow my instructions quietly, with a barely audible sigh of desire. The white coat has a vee neck. When buttoned your ample cleavage is seductively displayed. And the coat is almost too short to cover your stocking tops as you stand motionless.

"Spin around," I require, as I sit back down in my large leather chair and admire you while I gingerly try to arrange my still throbbing member in my pants. "Excellent. Gorgeous."

"Walk toward me." You take two steps to close the distance and as you do, the front of the lab coat parts just enough to clearly display the stocking tops, and even expose a bit of naked, tan flesh at the top.
