Caroline did peel away breezily once we got back to campus, citing previous obligations. I was forced to make my way, alone, back to my dorm room, hoping I could stand downwind of anyone I passed and that I wouldn't see anyone I knew. My clothes were still quite damp.
Maybe it was because everyone else was at dinner, but the sidewalks were mercifully empty. I made it to my room without incident and went immediately to take a shower.
I still wasn't used to the shared bathrooms. The majority of the dorms were co-ed, though a few residence halls were set aside for same-sex residents. With the dorms being co-ed, naturally the common bathrooms on each floor were also co-ed. As I had discovered earlier, it was very strange to be sitting on the toilet, with some dude on the lacrosse team taking a dump in the stall on your right, while a girl in the stall on your left chats to her friend standing outside.
And the showers -- though they were placed in individual stalls, there was little to protect anyone inside. There was only a curtain, which could be pulled for privacy, and a latching door which could easily be unlocked by an arm over the top, as I soon discovered.
I had been standing under the shower spray for several minutes, just letting it wash away the filth of the afternoon, when I opened my eyes and saw a face peering in at me. I yelped and jumped backward into the shower knob, jabbing the metal into my back.
"The professor wasn't in her office," Caroline said. "So I'm back. You really are your own worst enemy, aren't you?"
I was bent over, groaning, rubbing my spine where a bruise was sure to form.
"Budge over, nerd," she said. I straightened suddenly when I realized her bare leg was preceding her through the shower curtain and into the tiled stall; the rest of her followed. She was completely naked.
"Give me some room," she said, nudging me out of the way of the shower spray so she could take it herself. "You act like you've never seen a naked woman before."
"I haven't," I said, staring, without thinking.
"Like what you see, slave?" she smirked at me over one shoulder, then looked down. "I see that you do."
I reddened. But despite feeling uncomfortable, and under scrutiny, my cock only got stiffer.
"And I know that you like the way I talk to you," she purred. "I love how readily you submit to me..."
I had to close my eyes briefly to cut down on the amount of stimulation entering my system: hearing her voice, seeing her naked body, her face, her powerful expression, feeling so electrified already...
And then I felt her take a step closer to me. Caroline pressed her body against my body. Her perky little tits were crushed against my chest; my cock was flush against her stomach and leaking a little with arousal; I could feel the wisps of her pubic hair against my bare leg. My eyes popped open. She was looking at me with a strange expression, which quickly cleared.
"You're not entirely clean," she told me. "As my slave, you need an appropriate bath."
"A-"
Caroline began to answer my question through action before I could even get it out. She stood on her tiptoes, reached her hand down to her pussy, and spread her lips apart. We were still standing chest-to-chest. My cock was erect; as she settled back down onto flat feet, she trapped it between her own thighs.
My member was now nestled below her spread pussy. For one glorious moment, she rubbed the whole of her wet cunt against my cock. Then I felt the warmth of her pee bathing it, running down the length of my dick, clinging to the underside, falling to the tile floor below. It was a sudden, spreading warmth.
Meanwhile, she rocked back and forth a little on her heels, and, since she was still squeezing me between her thighs, I felt the friction against my own cock.
I shot my load against the tiled wall even before she had finished pissing; in the wet and the warmth and the intensity of having this naked girl pressed against me, it took no time at all for me to come.
"Damn," she said, not with disappointment but with impressed interest. "What a good slave."
Her piss flushed away the droplets of ejaculate beading at the tip of my cock, and then trickled away. "I do love a dirty boy who enjoys being cleaned."
I had nothing to say; I was still breathing heavily.
"My work for today is done," she said airily, stepping away, rinsing herself one last time in the shower spray, and exiting through the curtain into the changing area. Stunned, I followed her actions, a little more slowly, rinsing myself properly clean. When I left the stall, I realized that she had stolen my towel.
I had to hold my bundle of wet clothes in front of my crotch as I crab-walked down the hallway, hoping no one would spot me; naturally, two sophomore girls caught sight of me just as I was unlocking the door to my room. They skipped down the stairwell shrieking with laughter.
I was a little annoyed about the towel thing, enough so that I seriously considered re-locking the inner door between my room and Caroline's. But I didn't. It was still unlocked when I went to bed that night.
But, when I opened my eyes the next morning, Caroline wasn't there. She hadn't come in to wake me up. I checked the time. It surprised me a little, how disappointed I felt. Why hadn't she come? Maybe she wasn't awake yet?
I nervously puttered around my room for a while, listening for sounds of activity next door. I didn't want to change out of my pajamas, because what if she ruined my clothes? I didn't want to go to the dining hall for breakfast, because what if she stopped by while I was out? She wouldn't...punish me if I wasn't here and ready for her, would she? What would it be like, if she did...punish me?
I finished unpacking a box, and I arranged my new textbooks on my bookshelf, and I put a few posters on the walls. I unpacked the fancy coffee maker my parents had gifted me, rinsed out the inside, and started to brew myself a cup.
I was just sitting at my desk, staring at the bubbles forming on the top of the travel mug as it filled, when the door opened.
"Good morning, my little toilet," she called. "Ooh, that smells good. Are you making coffee?"
She looked at the cup, now almost full.
"You can have it," I said hurriedly. "I'll make another."
"Mmm. Good slave," she smiled. "Eager to please. I love that. And speaking of which..."
She looked at me seriously and pointed straight down at the ground in front of her. I slid off the chair, coming to my knees in front of her feet.
"I have to go so bad," she said, pulling her panties down and off. She laid them, all pink and cream and lace, over my shoulder, like I was a towel rack. "I mean it. I had so much to drink before bed last night, and today I overslept, and now... oh god, now I just feel like I'm going to burst. Hurry, toilet."
I didn't know how to hurry more than I was. I was already positioned in front of her, ready and waiting. But she was dancing a little bit, clasping her knees together, wriggling as if she was afraid that she'd leak all over the floor if she stood upright.
"Hurry," she moaned, and then she grabbed me by the back of the head and pulled me forward between her legs, as if trying to clamp me onto her cunt, to catch the flow in time: as it was, I barely made it in position before she couldn't hold it anymore.
"Oh, fuck, I'm pissing," she gasped, and already the flow was starting, welling up, right in front of my eyes. I hurriedly placed my mouth over her, but not before she spurted a little bit, over me and my chest and the floor.
"Fuuuuck," she sighed, releasing utterly into my mouth. "Mmmm, fuck, that feels good. My little piss slave has gotten so good at pleasing his mistress..."
I felt my cheeks get red, and not just because her legs were warm on either side of my face. My loose pajama pants were feeling a little tighter. I gulped and swallowed, feeling her warm fluids trickle over my chin.
"Oh, that's amazing," she moaned as her stream dwindled away. "Now, lick me clean, slave."
