—

Since our encounter in her dorm room, all I’d thought about was the nameless nerdy girl with the appetite for “my whore Kathy”.

That had happened last Thursday, I’d had the weekend to dwell on it, and every time I did I was instantly hard and my balls literally ached. She had left me with simultaneously the greatest and worst case of blue balls in history. But she also left me with a mission.

*Kathy’s Ass*

I didn’t feel any love for, or obligation to, Kathy. She was a classic college fling. I wasn’t even sure we’d defined what was going on between us to that point. Were we exclusive? Did that matter? I was half sure she was banging someone else too on occasion – only difference was she wasn’t actively trying to bang me up the backside to fulfill someone else’s fetish.

I felt a twinge of guilt but that didn’t stop me from calling Kathy and making sure she was showing up to my dorm room that Tuesday, around the same time she had right before my last Algebra class.

Kathy was a good girl and showed up on time for me, as she’d been told.

I thought of how I’d been a good boy and done as I’d been told for the girl who cuffed me to the chair and shoved her panties in my mouth.

My cock almost burst through my jeans.

Kathy could obviously see the lust in my eyes. She smiled. It wasn’t the devilish grin of the other girl – her smile was more wholesome. Her dimples popped and almost made a sound.

She started to say something and I stole a page from the playbook of the girl I was truly lusting for: I held my finger up to Kathy’s lips to silence her.

“Speak only when I tell you…” I relished this, god I could feel the blood rushing through my veins and all heading down to my erection, “Nod if you understand?”

Her smile didn’t fade; there was a gleam in her eye. I’d never been dominant with her but it seemed to be pushing the same buttons in her that had been pushed in me.

She nodded. I was so happy.

I wasted no time.

One of my hands was immediately tangled in the back of her hair, gripping it tight, pulling it between my fingers. I brought her face to mine and kissed her. I clumbsily pushed my tongue into her mouth and fucked her mouth with it. Her tongue found mine, fighting back against it with passionate submission. She was doing what I wanted, but not just sitting back. There was every bit as much lust directed at me as I was channeling into her.

My other hand rubbed her breast as we kissed. I pushed us back against the wall, pinning her there. My thumb trapping what of her nipple was poking through her shirt, and pressed it against the side of my trigger finger. I was needing at her. And listening, feeling, the change of her breath disappearing into my mouth every time I pinched her nipple so slightly.

It wasn’t long before I slid that hand down from her breast, over her stomach, and was pushing my finger tips between her jeans and panties.

I found the folds of her pussy through the material of her panties, and traced my finger tips up and down their lengths. Pressing hard on them and feeling her wetness coming back at me through the material.

I rubbed her wanting cunt through her panties. I pressed a finger between her folders and found her clit as best I could. I mashed it. I massaged it. I tried to pinch it. I let a finger linger there before shifting it lower and pushing material up into her soaking hole. I loved how she moaned around my tongue as I did this.

This was easily the most I’d enjoyed pleasuring a girl, and it had so much less to do with the one who I had my hand in, and everything to do with the one on my mind.

I pulled my mouth from Kathy’s just long enough to order her to, “Unzip and take off your jeans.” Before I started kissing the side of her neck, where the shoulder starts, about as aggressively as I’d been attacking her mouth moments before. I sucked it and licked it.

She whispered, “Yes sir.” And I felt her hands fiddle with her button and then zipper.

All the while I continued rubbing her pussy. I felt her undressing around my hand. I felt her awkwardly pushing the material down over her hips and peeling the material down her thighs, she got it about half way down them, just releasing my hand.

I immediately took advantage of the freedom this afforded me. I pushed her panties to the side and pushed two fingers full up inside her.

I heard her let out what was almost a scream.

I fucked her proper with my fingers now, but I pulled my face back from her neck, I looked her in the eyes as she drew in her breath every time I pulled my fingers from her pussy, then moaned loudly every time I pushed them back inside.

All at once I stopped.

She looked at me confused.

I pulled my hand from the tangle in her hair, and stepped back from her. Looking her up and down, examining the disheveled mess of lust I had her in, and loving the sight. She was leaning up against the wall, where I’d left her, where I’d pinned her without even being aware. The autopilot of lust had found the perfect spot for her.

I thought, “what would that crazy chick do now?” Then I thought even more primarily, “what would that crazy chick want *me* to do right now?”

And it was like she spoke through me, “I said take off your jeans. Do it.”

Obediently, and without a word this time, she finished the job she had started.

I’m sure my smile was like the one I’d seen in the darkly lit dorm room those days before.

“Now take off your panties.”

And as she did I noticed for the first time they were pink, cotton, and so much darker where she had soaked through them.

She pulled them down slowly, bending at the waste, stepping out of them, then stood back up holding them stretched between her thumbs.

She smiled over them, as she had smiled before. She looked almost drunk off lust, the same feeling I knew so well so recently.

She dared to speak, “Do you want them, sir?”

“Oh Kathy you… whore… you make too much noise.”

If her smile could get wider it did.

I stepped toward her. I grabbed the panties from her hands forcefully. I pressed body against hers and kissed her again, hard on the mouth.

I let the fingers that had been in her pussy stroke her cheek as I did this.

She returned my kiss.

I let the fingers slip between our kissing lips, then I fishtailed them into her mouth before pulling my mouth away.

I slid my fingers into her mouth and she sucked on them instinctively.

I rubbed the panties against her pussy as I did this. I pushed them into her hole to soak up more of her juices. I rubbed them again on her clit. I used them to get her off, to make her squirm more. And I used them to try to collect all her lust.

I asked her, “Whore, are you enjoying this?”

And she smiled around my fingers and nodded yes.

I did not stop my assault on her pussy. If anything I increased my intensity.

She shook against the wall. I loved seeing her shake against the wall.

I loved feeling her mouth suck her juices off my fingers more furiously, before going dead from lack of any concentration as she seemed to verge on orgasm, then moan around them as she finally hit it.

I swear if I’d even touched the front of my jeans I would have filled them with cum just watching this submissive little creature bend to my will.

It was hot, and I understood the nerdy girl’s desires oh so well.

I felt like I had Cathy against that wall for hours but I’m sure it was only minutes. She seemed to cum hard, I couldn’t count how many times. But when tears were streaming down her eyes and she panted before me I finally pulled my fingers from her mouth and I whispered, “Satisfied?”

She said, “Oh god that was amazing…” and before she could finish, I shoved the soaking pink panties into her mouth. As had been done to me.

There was shock in her eyes, but the lust had not faded, she was up for whatever this next part of the adventure was.

I stepped back and started undoing my belt. I stared her in the eyes and said, “Good, now bend over that desk you whore, there is one more thing I need from you…”
