Turning the page of my textbook, my phone dings with a text from my girlfriend saying, "Come over? I need you for smt." After putting on a cute shirt, the short black skirt she likes, and fishnets, I begin my walk to her dorm. She always liked this outfit, maybe I can turn her on enough that she'll fuck me. It's been about two weeks of flat denial, and I'm beginning to go crazy. Honestly, it's likely that she's studying for finals as well and just needs help, but just maybe she's as needy as me. All hopes of getting railed evaporate, however, when I open the door and she's at her desk. Probably studying then.

Without looking away from the screen, she gives a brief motion to the floor. I sink to my knees, waiting for instruction, clarification, or anything. After a few beats, it becomes clear that I'm not understanding an unspoken command. With a sigh resembling annoyance, she stares at me before saying, "Under the desk, mutt. Now."

I crawl the short distance to her desk, fitting myself underneath with some difficulty. Maneuvering my hands behind my back just how she likes, I take in the view. I can only see her lower half from this angle, and it's rather dehumanizing how impersonal it feels. Her knees spread wide in front of me, she pulls her cock out from her sweatpants, not bothering to take them all the way off.

Eagerly, I lean forward to get her in my mouth -after all, it's one of my favorite tastes- but it only gains me a kick to the ribs. I flinch backward, hitting my head on the desktop above me as she laughs.

"Dumb bitch, did you forget your training? You're supposed to ask before your treat. Try again."

"Please ma'am," I mumble, avoiding eye contact, "let me have your cock in my mouth."

While normally she'd punish me for not speaking clearly, she just rolls her eyes and pushes my head onto her cock. My eyes water and I gag as she pushes herself into my throat, my nose touching her bush. I could go drunk off of that scent.

"Yeahhh, I didn't want to get up, and you're an alright urinal," she says, relaxed, as I feel her piss start to trickle into my throat.

Eyes widening, I start to pull back but she grabs a fist full of my hair and forces me back down. Remembering the pile of energy drinks around her desk I saw upon walking in, it dawns on me that she has been holding her piss all day, and that I'll be in for a challenge. Satisfied with how deep she is in me, she begins pissing properly. I sputter and gag, my hands fighting to stay behind my back instead of push her away from me. She seems to not care for my struggles, however, and continues playing her game, letting out a small sigh of relief.

"Honestly, I know you were studying for finals but this is just more important. Plus, you're such a disgusting freak, you probably like this," she says, not looking away from her computer. Im fighting to not choke, to swallow everything properly, but it's overwhelming.

Finally unsheathing herself from my throat, I gulp breaths of air, the taste of her piss still strong in my mouth. Before I can say anything, she beats me to it. "Cute outfit, mutt."

I open my mouth to thank her, but before words can come out, she aims her cock at my tits and lets loose once again, quickly soaking the thin fabric.

"Thank me for not making you drink the rest like the urinal fag you are."

Shirt fully soaked, I feel the fabric cling to me uncomfortably. "Thank you ma'am," I whimper, hoping she'll be done soon. Honestly, it's only been about three seconds, but it's felt like an eternity. Apparently, she decides so too, because with a bored expression she pulls me out from the desk. Despite the short period of time of my residence, my knees ache from suddenly standing, and she seems to enjoy my discomfort.

"Strip."

Peeling off my soaked outfit, I stand in her dorm naked, a faint sheen of piss still evident on my tits. She wordlessly takes a picture of me, sending it to someone. In a breath, she's got grey sweatpants and a hoodie of hers in her hands, offering them to me. She's not subtle in the way that she pockets my underwear.

Pulling on the sweatpants, I'm pleased with the texture and warmth. The comfort is short-lived, however, as she releases the last drops of her bladder onto the crotch of my only available, dry clothes. Although not much, the piss seeps into the pants quickly, darkening it. She laughs quietly as she wipes the last drops on my pants. "Good luck not getting any weird looks walking back in pissy pants, freak. You're far too old to be pissing yourself. Maybe I should get you some diapers, since you clearly can't control yourself."

I protest that she was clearly the one who made my pants wet, but she only gestures for me to lick her cock clean. Dropping to my knees, I take her into my mouth. I know better than to be bothered by the taste, no matter how unwashed, sweaty, and piss-tasting her cock is. I let my tongue clean her off, allowing my thoughts to drift until she pulls me off of her.

"Good dog. I bet that tasted sooo good, hmm?" I know better than to disagree

"Well, it's no matter, why should I care what a toilet thinks. Thanks though, that's a lot better. You know, I held all that piss just for you, you really ought to thank me," she goads, eyebrows raised. She crosses her arms, looking down at me.

Slowly, I bend down to her feet, my face burning with shame, and deliver a chaste kiss to each foot. She makes a pleased, amused noise, which I take as my cue to stand up.

Remembering my foolish hope of cumming, I sigh quietly. At my badly-concealed disappointed face, she adds, "Oh yeah, it's been a couple weeks since you've came. I guess you have been an obedient piss pup, you deserve a reward."

My hope in an orgasm in the near future grows until she decides, "I haven't showered in a couple days, you can clean my ass. That'll be a good reward for such a gross piss-drinking pervert."
