Give her what she wants. Good and hard

You actually hesitate for a moment, then hastily undo your pants and let them fall to the floor, kicking them off your feet as Diana looks back at you, wriggling her paddled rump and whimpering softly. She widens her stance, parting her thighs further, giving you a glimpse of her drenched and swollen labia. Your cock is straining to plunge into her, but somehow you manage enough restraint to take it slow, gently stroking her reddened rump with one hand as you rub your shaft between her sodden folds.

She's not having any part of slow. With a feral grunt she rocks her hips, capturing your cock and impaling herself fully, emitting an long deep groan of animal pleasure. She starts to grind back against you, rocking and bucking as she arches her back and gasps frantically, slapping at the desk with **** urgency.

Her frenzy strips away the shreds of your restraint, and with a growl you grab her hips and start to pound into her, meeting each grinding twerk of her hips with a deep and brutal thrust. Her cunt feels hot and wet and tight and incredible, made all the better by your anticipation of this moment, your mind fogged with lust and need.

At this rate you're not going to last long, but you don't care, needing only to fuck this woman you've lusted after since you first saw her, to possess her and fill her with your pulsing meat.

She's moaning and gasping in her own frenzy, her body shuddering with spasms. All trace of the prim headmistress is gone. This is a horny animal in heat, caring only to be fucked senseless. You're only too happy to oblige, thrusting into her tight wetness and feeling like you're a yard long.

"God Yes!" she grunts, finally finding some words. "Fuck me! Fuck me hard! Harder! Oh Fuck that's so fucking good! Fuck me like a bitch!" You hold her hips, squeezing the ripe flesh of her ass as you thrust, loving the feel of her satin skin. You pull the cheeks of her ass apart, exposing her sweet brown rosebud, then teasing it with a finger.

"Oh Fuck Yes! Is that what you want? Put your finger in my fucking ass? Do it to me! Oh Fuck do it to me!" she glares over her shoulder, her face a mask of maddened need, her eyes suddenly opening wide as you press your finger into her tight anus.

"OH FUCK!" she howls. "I'M FUCKING COMING! OH FUCK I'M COMING LIKE A BITCH!" her body writhes and convulses as her orgasmic spasms take her, her tight holes squeezing and milking your cock and finger as she slaps the desk in her frenzy.

"Oh Fuck!" you groan, as you feel your balls tightening, ready to explode. You grab her hips and thrust deep, straining towards a finish that isn't far away.

"Fuck! Fill me up! Fill me! I want it! I fucking want it!" she groans, her voice rising in pitch as her body shuddering and quivering in ecstasy. She suddenly crams her panties back into her mouth, slapping the desk madly as she squeals into the gag, her tight wet tunnel squeezing and milking you.

That's the final trigger. With a roar of triumph you explode inside her, pumping what seems like gallons of spunk into her hot wet cunt as the two of you buck and writhe, locked together like rutting animals.

Sated and gasping, you slump on her, stroking her face as you do. She pulls her panties out of her mouth and nuzzles your fingers, her breathing heavy, her eyes half lidded and wanton.

"You brute," she breathes. "You utter brute."

"Are you sorry?" you ask, wondering if she's having second thoughts.

"You know I'm not. It was exactly what I wanted. God, I'm such a slut sometimes. You fucked my brains out, you beautiful brute."

"I'm feeling a little brainless myself," you say softly. "That was incredible."

"Maybe you spurted all your brains up my pussy," she chuckles. "Let me up now. We've got another meeting soon and I can't go to it looking like I've been fucking like a bitch in heat."

When you stand up and pull out of her she gives a little sigh before rising. She looks at the panties she holds in her hand and with a teasing smile pushes them into your shirt pocket and leans up to kiss you softly. "As Miss Newton said, keep these for your collection Dean Hawkfeather. Now I'm going to borrow your bathroom to freshen up."

With another smile she picks up her skirt and slides open your bedroom door, giving a twitch of her rump as she turns towards your bathroom.

Part of you wants to follow Diana and pull her onto your bed for a second round. This time slower and more gentle and lingering. You shake your head to rid yourself of the image of her sprawled naked and wanton on her back as you savour each other, telling yourself that there is no time for such dalliance. Instead, you straighten your clothes and rub your hand across the surface of your desk with a smile. Remembering the panties Diana stuffed in your shirt pocket, you pull them out and rub your thumb over the lacy fabric with a smile before putting them in a desk drawer.

Within a few minutes Diana emerges, restored to her austere Headmistress look. She gives you a smile and puts a hand on your arm, leaning up to kiss your cheek.

"That was very sweet Kyle. But we've got to get going. Let's talk about this later." She squeezes your arm and turns away before you can respond, opening the door and leaving you standing alone. With a sigh you use your bathroom to wash up and check your appearance before leaving your office and heading to the main building.
