At least the girl showed up today for class.

Purity showed up to class and turned in her assignment, the one that she was supposed to have written while on my face last night. I intended to keep my mouth buried between her legs until she wrote the entire thing.

That was, until she ran out of my house like a scared little girl.

I took off after her in my car, thinking I'd see her walking on the sidewalk on the way back to campus, but I didn't. My text messages to her went ignored.

Today, she's dressed in one of the floor-length garments she wore when the semester began.

She tries to slip out of my class, as if I'm not going to notice her doing so. She tries to squeeze her way through the crowd of students in the hallway, obviously attempting to avoid me, but she collides with another student, sending her notebook flying to the ground. When I pick it up and hand it to her, her face goes pale.

"My office," I tell her softly.

"I can't."

I'm irritated with the girl for panicking and running from my house last night instead of talking to me about how she felt. I'm beyond irritated that she doesn't trust me enough to talk to me now.

"My office," I growl, leaning close to her and pretending to just be giving her back her notebook. I pretend to be a professional, despite being the least professional person in the world. "March your ass to my office immediately or I swear to you that I will drag you there by your hair right in front of everyone. I don't care if it gets me fired or not. Then I will bend you over, pull up that dress, and fuck you on my desk."

Purity looks at me with eyes as big as saucers, but I turn around and walk away.

I'm acting like a goddamned caveman.

I have enough insight to be aware that I'm behaving like an insane person. I just don't fucking care right now.

I've been wrapped around the axle since the girl walked out on me last night – and not only because she left me with the biggest case of blue balls in the history of the universe. I've been jacked up and on edge because I pushed her too far.

I knew that as soon as I saw the look on her face after she orgasmed.

Can I really be blamed for pushing her boundaries the way I did? I'm losing my fucking mind over the girl. Every experience with her is completely new, a first time every time we meet. I'm giving her a million first times, and it's making me crazy.

The thought of her shedding her inhibitions and having a public orgasm – on the phone with her father, the asshole who insists on continuing to control her life from afar, no less – pushed me over the edge. I couldn't help but want her to do it.

I couldn't help but want her to let go.

My execution might have been wrong, but my intentions were good… in a really fucked-up way.

Of course, my execution a moment ago was just as fucked up, with the way I told her I'd drag her by the hair to my office and fuck her. But I'm not logical when it comes to this girl. I'm not reasonable and I'm not rational. Nothing I do with her makes any kind of sense.

Honestly, I'm not sure she's even going to show up to my office, but she does. She walks through the door, her hands clasped together, looking every inch like a nervous, lost little lamb.

A pang of guilt rushes through me for causing that. I don't want the nervous, timid little girl. I want the woman who has been transforming into someone who is ever more sure of herself, more comfortable.

More reckless.

I want the woman who had begun to throw caution to the wind.

Purity closes the door behind her, a pained expression on her face. "I didn't mean to run."

I step closer to her. She smells like strawberries, like she got a new shampoo or body wash, and I want to pull her against me and bury my nose in her hair.

Fuck, I want to bury my face in her breasts and between her legs.

I want to know if all of her smells like strawberries today.

"Did you have a change of heart?" I ask.

"I don't know…" she whispers. "It was so… so… crazy… and then my father was talking about church, and…"

"And you came while he was on the phone."

A pink flush rises on her cheeks. "It was so…"

"Bad?" I whisper. My mouth goes near her ear and she squirms in response, tilting her head toward me as she lets out a little whimper. "Something a good little preacher's daughter would never do?"

"Exactly," she murmurs. "That's the… the worst thing I can think of."

"Oh, I can think of far worse things than that."

Fuck, the kinds of things I can imagine doing to this girl…

Obscene things.

Everything I want to do to her is obscene – because of who she is, because of who I am. Because of how young she is. Because of the shitty relationship I have with her father.

I can't help but think of them anyway. I can't help but want to do so many more obscene things to her.

"I'm not sure," she starts, inhaling a deep breath. Her cheeks are dewy. "I'm not sure if I can do this."

"Is that why you dressed like this today?" I ask. My finger slips under the edge of the neckline of the dress, and Purity lets out the tiniest of moans. "Were you trying to dress modestly because you thought it would make you unattractive? Were you trying to avoid turning me on?"

She looks up at me. "I was trying to…I was trying to keep myself under wraps," she explains softly. "I was trying not to be –"

"Not to be what?" I palm her breast and she arches her back, pressing against my hand.

"Not to be out of control."

"If you want me to stop, just say the word, Purity. I'll stand here, and you can turn around and walk away."

"Don't stop," she pleads. I squeeze her full breast through the fabric of her dress and she presses her palm flat against my chest. When I grip her ass cheek with my hand, she clings to my shirt, fisting the material like she's afraid she's going to fall.

"Why did you run?"

"Because of what happened. You made me come on the phone with my father."

"You were ashamed?"

When she bites her lip and nods, my heart softens. Fuck, this girl will kill me with her big sorrowful eyes and her nervousness and her goddamned preoccupation with being good.

I take her face in my hands, wanting to kiss away all of her uncertainty. "I'm sorry, Purity," I tell her. "If I pushed you too far... if it was over the line... I'm sorry."

So much for being anything except a damned sap. I don't know what's wrong with me.

"It wasn't you." Her cheeks redden. "It was me. I came so very hard."

"I don't understand," I tell her. "You're ashamed because of how hard you came?"

She nods. "I was on the phone with my father. Something has to be wrong with me, that I was on the phone with him and came that hard. Something's completely wrong– "

"Stop. Nothing's wrong with you, Purity." I cut off her protests by putting my lips against hers. Her body softens against me. "You're perfect."

"You're just saying that because you want to put your cock inside me."

I can't help but laugh. "That's true. But that's not the only reason I'm saying you're perfect. I'm saying that because you are – and you have nothing to be ashamed of." Leaning in close to her, I whisper in her ear, "You came so very hard on my face last night. Do you know how badly it made me want to make you come hard like that on my cock?"

She whimpers. "I wanted that, too."

"Instead, you fucked my face and ran off, leaving me with a huge hard-on that I had to take care of myself," I tell her sternly.

"I'm sorry," she stammers.

I sigh exaggeratedly. "And to think I was going to give you a lesson on what to do with an erection."

She bites her lip. "Maybe you could still show me?"

"I don't know." I pretend to have to consider the offer. "Can you promise me you won't run away screaming this time?"

A smile begins to form on her lips. "I don't know. Is it a big erection?"

Taking her hand, I press her palm against my crotch. "You tell me. Do you think your little mouth can handle it?"

"I'm not sure," she whispers, looking up at me. "I – I really don't know. I've never done it before."

"I know," I growl. "But you're going to have to make up for running away last night, aren't you?"

"What exactly should I do to make up for it?" she asks, her eyes on mine. Her fingers go to my belt, and I let her unlatch the buckle. She unbuttons my pants and then reaches for the zipper. I groan as she pulls down my pants and my boxer-briefs.

Then she takes my cock in her hand, her fingers around the shaft. She inhales sharply as she runs her palm up my length.

"What do you think you can do to make up for it, little girl?" I really need to stop calling her that. The woman in front of me is anything but a little girl.

"I think…" Her voice trails off as she touches the tip of my cock with her thumb, catching a drop of pre-cum. Then she brings her finger to her mouth and tastes me. "I'm just not sure."

The tease.

I grab a handful of her hair. "You ran away last night, but you're not running away this time. You're going to open those sweet lips for me. I'm going to fuck that perfect mouth the way you rode my face last night. I'm going to come in that wet little mouth the way you came on my face, sweetheart, and you're going to swallow every last drop of me."

"Yes, Sir," she whispers.

Before she can fall to her knees, though, there's a knock on the door. Purity's eyes go wide and panic crosses her face.

"Just a second," I call as I realize that neither of us locked the door, and I'm standing here with my pants undone and my cock out.

In the presence of a student.

"It's me, Professor Ryan."

I roll my eyes. The English department assistant has the worst timing in the world. Gina has also seen Purity in here once before. Twice would be extremely suspicious.

But I have an idea. A wicked, terrible idea.

"Get under my desk," I tell Purity.

"I'm not doing that," she hisses.

"You can and you will," I order, pointing toward the large piece of furniture. It's one of those antique executive desks, a monstrosity that overwhelms my office, but it came with the office. It also has a large space underneath that will fit Purity perfectly – and goes all the way to the floor so that no part of her would be visible underneath. "On your knees under the desk."

I think Purity might tell me to go to Hell, but Gina knocks again, and Purity scrambles for the desk. I follow suit, sliding into my office chair and pulling it tight just as Gina opens the door.

Logging into the computer, I feign business as Gina steps inside my office. I pretend to be hard at work, when really I'm just hard underneath my desk with my pants unzipped and Purity between my legs.

I don't know when things started getting completely out of hand when it comes to Purity, but I'd say that the current scenario places them firmly within the realm of totally fucked up.

They head further in that direction when Purity wraps her hand around the base of my shaft. Her touch surprises me, giving me a jolt that Gina notices.

"Are you okay, Professor Ryan?" Gina asks, giving me a puzzled look.

I clear my throat as Purity runs her hand up and down my length. "Of course."

Part of me can't fucking believe this is happening. Sure, I told Purity to hide under my desk, and sure, I kept my cock out – but I didn't entirely believe that the same girl who tore out of my house last night because she was embarrassed would be under my desk touching me while the English Department assistant is in my office.

Then her mouth wraps around the end of my cock. It's warm and wet and the best sensation I've ever felt.

My eyes close because I can't help but need a moment to savor it. It's that good.

"Professor Ryan?"

Fuck, that woman might have the most annoying voice in the world.

"Yes?" I choke out the word, my voice hoarse and raspy like I have a two-pack-a-day smoking habit. As I clear my throat, Purity sucks me deeply into her mouth.

I fucking lose my mind.

My palm hits the table hard, an automatic involuntary reflex, and a "bang" echoes through the office. My eyes bug out of my head, and I imagine I look like one of those old cartoon characters as I exclaim, "Holy shit!"

"Excuse me?" Gina wears a startled expression.

Purity swallows me. The girl puts her fingers around the base of my shaft and guides me so deeply into her throat that my cock grazes the back of it. I think I hear her make a gagging sound that would be so fucking hot if Gina weren't standing two feet away. I cough loudly to cover it – but also to distract myself from coming down the back of her throat right this instant.

"Professor Ryan!" Gina says, her voice sharp.

"Yes!" I reply far too loudly as Purity works me with her glorious lips.

I'm going to fucking die.

This girl is sucking me so hard that I'm going to slide right off of this chair. I'm going to fuck her mouth and I will fall off this chair right in front of the very gossipy English department assistant.

"Well, I wanted to let you know that Professor Erdinger suggested you'd be interested in attending the interdepartmental meeting in his place," she informs me. "The meeting is tomorrow."

Gina is saying something about scheduling and no one else being available and it being advantageous for my career for me to attend one since I'm not tenured and – oh my God, how the hell is this girl doing what she's doing with her mouth? If I didn't know her for as long as I've known her – and if I didn't know her father and how without a doubt she's the most sheltered girl in the world – there's no way I'd believe she was remotely close to being a virgin.

Not with the way she's sucking my cock right now. She's confident in her movements, her tongue stroking and flicking me like an expert.

Her mouth is so damned warm and wet, I'm practically gushing pre-cum. She sucks me harder, swallowing it down. If Gina weren't still droning on about what I can expect at this meeting, I'd grab Purity by the hair and pull her all the way down on my cock so hard it would make her eyes water.

I would come down the back of her throat and make her mine. I'd teach her never to run out on me again.

As it is, I'm completely at Purity's mercy, my hands above the table and unable to guide her in any way.

"Professor Ryan?" Gina's voice is insistent.

What the fuck do you want?

I have a hard time not screaming the words at her.

"Yes?" I gasp as Purity pulls me out of her mouth, her hand running up and down my length, her grip uncertain as she jerks me off. The girl has no idea how close she is to getting a face full of cum right now as she runs her tongue over the head of my cock. My balls are heavy and full and I try to focus on Gina as they tighten.

I have to get myself under control.

I'm certainly not going to come right now while Gina is talking to me. It's not that I have some kind of moral compunction or prohibition against it. It's just that I want to be rid of Gina.

I want her to leave so I can savor Purity's virgin mouth here in my office. I want to be able to fuck Purity's mouth the way that I want to. I want to tell the girl exactly how much I'm enjoying it.

"So you'll attend?" Gina asks. "I can tell Professor Erdinger that you'll go in his place?"

Purity chooses that exact moment to take me all the way down her throat again. She's jerked me off until I'm at the edge of exploding, and now she wraps her lips around me tightly and takes me down her throat.

Then she cups my heavy, full balls.

The entire thing happens in a matter of seconds, and takes me completely by surprise. I'm desperately trying to hold on, desperately trying not to come, desperately trying to be restrained.

Then this girl sucks me hard, and I come.

"Fuck, yes!" I exclaim loudly, my palm slapping the top of the desk hard again. My balls clench tightly, and then I release everything. I come so fucking hard that my eyes close tightly, and I lose touch with anything else in the world except for Purity's mouth.

I come and I come and I come and Purity swallows everything.

"You don't need to get angry about it," Gina huffs. "I was just asking. I thought it would be a good career opportunity, and besides, Dr. Erdinger requested you specifically."

"Huh?" My cock is spasming. I can't listen to a thing Gina is saying because I'm going to keel over right here on the desk as I come. I can't seem to stop coming. It's fucking ridiculous. "I'm not angry. I'm just – holy shit – I'm in the middle of a – fuck. I'm in the middle of a fucking chapter. A chapter."

Gina glares at me as Purity keeps sucking. I'm like a goddamned fountain at this point.

"There's no excuse for rudeness," Gina snips before flouncing off.

"I'm happy to do it," I call after her as she mutters something about diva artists under her breath.

The door swings shut behind her.

"Holy shit," I breathe as I push away from the desk.

Underneath, Purity is on her hands and knees. She looks up at me, flushed, and a smile spreads across her face. She reaches up to wipe her mouth, letting out a giggle. "That was so…"

"Hot?" I finish for her.

She giggles again when she bumps the top of her head on the underside of the desk as she crawls out and puts her hand in mine. I pull her up to my lap, my bare cock against her ass, and she leans back on my chest. "I was going with hilarious, but hot works too."

"So you thought it was hot to suck me off in front of someone else?" I whisper in her ear as she squirms against my lap.

"Maybe," she admits softly.

The girl is kinky. That's why she ran last night. She wasn't disgusted by what we did; she was turned on – and that scared her.

I inch up the fabric of her long dress, little by little, until it's up over her thighs. Then I pull one leg and then the other one to the side, splaying them out so her legs are positioned on either side of mine. "Say it," I order. "Getting me off and swallowing every little drop of my cum, while Gina was standing right there, was hot as hell. Wasn't it?"

"It was."

I pull her dress up farther, exposing her pussy.

She's not wearing any panties at all.

"Oh, fuck," I breathe into her ear. "You waltzed your little ass into my class in this dress, pretending to be modest, insisting that you were trying to be modest. But you wore absolutely nothing under this dress."

"No, Sir," she whispers.

"Tell me why," I growl as I slide my fingers between her legs. "Tell me why you were bare under this dress."

"Because I still wanted –"

"You still wanted what?" I ask her. My fingers glide easily over her swollen clit because she's so fucking wet. "Sucking my cock like that got you all soaked and ready for me, didn't it, little girl? You know what, I'm not calling you that anymore."

"I still wanted…" She inhales sharply as I roll my fingers over and over her clit. My other hand glides down the top of her dress and inside her bra, my fingers going straight for her nipple. "Why aren't you going to call me little girl?"

"Because you're not a little girl," I tell her. She arches her back, rocking on my leg as she tries to encourage me to slide my fingers inside of her. She's greedy and demanding, always trying to take control.

"What am I?" She moans softly as I press my fingertips against her entrance to tease her. She's soaking wet and ready for me, and my cock begins to harden as she grinds on me, her hips arching as she tries to get me to put my fingers in her.

"A dirty girl," I tell her. I don't tease her any longer.

I don't torment her and I don't fucking warn her at all. I plunge two fingers inside her tight, wet pussy.

For a split second, I almost feel badly for not being gentle with her.

Then she moans and writhes on my lap, and I realize she fucking loves it.

"Dirty little girl," she whispers.

I let out a growl against her ear, a low rumble I can't control. Pushing my fingers deeper inside her, I pinch her nipple at the same time. "I thought you hated being called little girl."

She moves against me as I fuck her with my fingers. She lets out a long groan.

"Oh, that's it, isn't it?" I ask, referring to the spot that I hit inside her with my fingertips – but also to the diminutive name. "Little girl… little girl… is that what you like being called?"

She rocks her hips faster in sync with my movements. Her pussy tightens around my fingers quickly, then more and more as I whisper in her ear, "My dirty little girl."

Fuck, I can't get enough of her like this – sitting on my lap with her dress pulled up and legs splayed out wide, her bare pussy on display as she faces the damned door of the office.

The unlocked office door.

Anyone could walk in right now.

Anyone could burst in and discover us and destroy my career. Eradicate it.

Demolish me.

I'm so reckless that I don't care.

"Your dirty little girl," she moans.

My fingers fuck her harder as I whisper in her ear. "Did the dirty little girl like sucking her teacher's cock?"

"Yes, yes, yes," she whimpers. I can feel her orgasm building with every stroke of my fingers. I can feel it with every little bit she tightens around me.

"Careful," I warn. "Don't be loud or someone might walk right into the office and catch you like this."

She lets out a whine. "I'm going to… Oh, God."

I don't stop talking in her ear. "Anyone could open that door and catch you like this, sitting on my lap with my fingers inside you. What would your daddy say if he knew I had my fingers in his little girl's pussy?"

She moans. The dirty little girl moans.

Despite her protests to the contrary, despite her running like hell last night, what she did turned her on.

What she's doing with me now turns her on.

"Hurry, sweetheart," I tell her. "If you don't come soon, someone's going to walk in here."

"I'm…so close," she whimpers. She grinds against me harder, fucking me back as I thrust my fingers deeper inside of her. Her breath is ragged, her shoulders pressed against my chest as she arches her hips to meet my hand over and over.

"This wet little pussy is mine," I murmur. "Your body is mine. I'm going to take it over and over and over. All of you belongs to me, little girl."

"Yes," she moans. Her pussy tightens around my fingers.

"What are you?" I ask.

"Your dirty little girl," she gasps. Then her back arches and her whole body tightens as she comes up off my lap for a brief moment, exploding on my fingers. Her orgasm rips through her so hard that I think she might squeeze my fingers right off of my hand.

She clasps her hand over her mouth to stifle the yelp she lets out. Muted by her hand, it sounds more like a squeak than a moan, and it almost makes me laugh out loud. I can't laugh, though, not with this girl having an orgasm on my lap.

She's too fucking hot for anything she does right now to be funny.

When she collapses against me, I sit there for a moment listening to her breathe, rough and ragged, in the room. I sit there with my fingers lodged deeply inside of her and wait for her to recover.

"My dirty little girl," I remind her.

Mine.
