Emma did as she was told, leaning her forearms on the wooden lectern, keeping her knees straight so her trunk was almost parallel to the floor. Her top was still up under her armpits, her tits hung beneath her, heavy and free, distended by gravity. I undid her skirt and pulled down the zipper, then yanked it down over her hips and let it slide down her legs. She stepped out of it, giving a little mewl of embarrassment at appearing so naked and exposed in so public a place as an auditorium, but she didn't protest. Her panties were thin, robin's egg blue, stretched across the firm globes of her buttocks and low enough so the top of her ass crack was visible, tight enough so the ripe bottoms of her cheeks emerged from beneath as well. I ran my hand over her ass, feeling the warmth of her skin through the thin, slick fabric as she looked nervously back at me over her shoulder.

"Eyes front," I said as I caressed the humid pit of her sex between her legs. "So you weren't sure? You weren't sure you were going to give me this ass tonight?"

"Connor, I--"

I drew my hand back and gave her a good hard slap on the underside of her right buttock--a loud one, a slap that echoed in the empty auditorium like a gunshot and made her squeal and rise up on her toes in surprise.

"Owww! Conner! No! No! That's not what I meant!"

"Keep your hands on that lectern! Don't you dare take them off, Emma!"

Whapp! I slapped her on the left cheek, just as hard, hard enough to make her drop her head and gasp, her fingers digging into the edge of the lectern as if she had to hang on.

Smackk! Slappp!

Two more blows, one on either cheek, hard and sharp, and now my hand was starting to sting and her ass was jiggling and beginning to redden. The sting felt good and, as I spanked her again, Emma gasped and jerked her head up, her mouth open in shock and something else--surprise maybe, but surprise at her own reaction, at finding she liked it, liked being spanked like this, treated like a naughty little high school slut.

I spanked her again. I was standing behind her and just to her left so I could swing my right hand back and land my blows squarely on the center of her ass, right on top of her innocent blue panties as her buttocks quaked and trembled and clenched together in reflexive avoidance.

Her hands were holding onto the top of the lectern and she lowered her face and rested her cheek against it, her brows knitted against the pain as she awaited the next blow, and how the emotions tore at me as I spanked her! Her fragile beauty and the way she offered herself up to my punishment brought out something both savage and tender in me, and I stopped the spanking, reached in front of her with my left hand and found her pussy and began to caress her, massaging and stroking her the way I knew she liked, washing away the pain with soothing tenderness. I caressed her ass as well, sliding my hand over her slick panties, feeling the heat from her beaten flesh through the fabric. The softness felt good, soothing against my tingling palm.

Emma began to grind herself against my hand, tentatively, as if checking to see whether the storm had passed. When she received no further spanks, she grew bolder. She began to search for pleasure, rolling her hips and ass as she pushed her pussy against my fingers, working herself off. She became hungrier, more desperate.

My fingers pressed the fabric of her panties up into her sticky slit and it felt as though she might somehow actually open up and take me inside, and at that point I realized she was about to seduce me with her need.

I drew my right hand back and started spanking her again--Slapp! Whapp! Crackk!--smacking her ass as I continued to massage her pussy, mixing pleasure and pain, sweetness and thunder, until Emma was clinging to the lectern and almost sobbing, humping and writhing like a bitch in heat, not sure which way to turn.

Now I was sweating too, my hand numb, my dick throbbing and oozing in my pants. I stepped back and pulled off my necktie as Emma writhed and moaned against the lectern, swiveling her ass shamelessly. I grabbed her wrists and used the tie to bind them behind her back. She didn't resist, just lay there with her face pressed against the hard wood as I roughly tied her wrists together and she panted with urgent excitement. Even as I pulled the knot tight, her ass continued to weave and undulate in lascivious invitation as if it had a mind of its own and was hungry now for more punishment, more pleasure, for whatever I wanted to give her.
