As a result of my trip to the toilet, I was a bit late to lunch, so when I eventually arrived, past the admonishing wagging of a teacher's finger, Nuba had already started eating.

“There you are,” she said. “What did I tell you about being good today?”

“Sorry,” I replied, sitting in my seat. My meal was already there, thankfully. Students had been known not to get served when they weren't on time.

“I had to tell them to bring your dinner, I said you were feeling a little unwell,” she said. “Where were you?”

“I... had to stop at the toilet.” I went red and looked at my food.

“You...!” Nuba stopped and looked around, before ducking her head and speaking in a whisper. “You stopped to play with yourself, didn't you?”

“I... I... It was the showers!” I hissed back. “You don't know what it was like! There were... girls all over the place. Naked girls!” Even as I whispered this to her, visions of the shower room flashed back to me, and I trembled a little.

Nuba pursed her lips and sat back in her chair, tapping the table with her fingers as she looked at me.

“Don't look at me like that,” I hissed, going even redder. I looked down, trying to hide my face.

She leaned forward again. “Okay, we'll talk about this later. I'll think of something. Did you get a confirmation message?”

In all the kerfuffle I'd forgotten to check! I pulled out my pad and tapped on the messages icon, then scrolled down until I found what I was looking for.

“Yes,” I said, after reading it. “It's all good.” I tapped the confirm button, and smiled up at Nuba.

“Well, that's a relief,” she said. “I'll message you later if I hear something. You've a free period last session you said?”

“It's a study period,” I corrected her.

“Ever the goody goody,” she smiled, waving a spoon at me.

“Hah, if you'd seen me in P.E you wouldn't have said that,” I retorted.

We both giggled.

The afternoon lesson went more smoothly than gym, thank goodness. I liked tactical theory, and Ms. Hammerstien was a good teacher.

After class, I made my way to the library, and laid out my study materials. My evening sessions with Nuba had left me behind in my schoolwork.

Near the end of the session, my pad beeped. It was a message from Nuba. We were now officially room mates! I smiled at the missive, and tapped in a reply.

Scooping up my things, I excused myself from the library and made my way back to my room, my old room now. As I arrived, my synth was just emerging, carrying a large box.

“I have taken the liberty of packing and moving your things,” it said. “This is the last box.”

“Oh, nice, thanks,” I said. “Hold on a second please.”

“Of course,” it said.

I stepped into my room and looked around. The place was bare now. The few posters I had had, had been taken down, and all my nik-naks packed up.

Still, I'd spent the last seven or so years here, and I was a little sad to leave it.

“Nothing stays the same except change,” I said to myself, quoting an ancient saying. With one final mental goodbye to my room, I turned about and joined the synth in the hallway. “Right, where are my new quarters then?” I asked it.

“Follow me,” it said, setting off. I followed.

My new room was upstairs, a place I'd only ever ventured a few times. It was quieter here, and the carpets were a different colour. We walked along the, wider, corridor, until we arrived at door number fifty five, which slid open as we approached.

The synth went in first, and I followed.

Nuba was already there, sitting on one of the two beds that were placed next to opposite walls.

“Hey room mate!” she said, jumping up and hugging me.

“Hey yourself,” I said, smiling back. “You may go, thank you,” I said to the synth.

“Very well.”

As soon as the synth had gone, and the door was closed Nuba pulled me in close, and snogged me hard. Her hands wandered down, travelling under my skirt and then over and into my panties.

“Ooohhh, Nuba,” I moaned, as her fingers explored my special place.

“Look at other girls will you?” she whispered to me, but she was giggling.

“There was so many nice ones!” I gasped back, squirming as she played with my pussy.

“I'll show you nice you little bitch!” she replied, pushing me back onto the bed she's been sitting on.

“Oh Yes! Oh my universe!” I gasped. “Talk dirty to me!” I panted, as she pulled my underwear off.

“You little slut,” she hissed, pulling my legs wide. “You'd service half the girls in the school given a chance, wouldn't you?”

“Oh yes yes yes!” I cried, as she went down on me, working my clit with her tongue. “I'm a bad girl! Such a baaaaaaad gaaahhhhh!!” I couldn't carry on, as it became too much for me. My whole body jerked as I came. “Fuucckkk!” I had to clamp my hands over my mouth as Nuba didn't stop, making me shake and shudder. “No, stop, it's too much! I can't... Oh ahhhhh!” I climaxed so hard that I lost control of my bladder, and pissed into Nuba's face.

“Oh ho!” she gurgled, putting her lips over my piss hole, and gulping the liquid down. This dirty, dirty act alone made me cum again, one final time, before I slumped back, covered in sweat and exhausted, my heart beating ten to the dozen.

I managed to regain control of my bladder, and Nuba crawled up my body, leaking pee all over my blouse and blazer. She worked her way up to my mouth, and kissed me again.

I melted against her, kissing her back, tasting my own piss and pussy juice on her lips. I didn't care.

I'd totally fallen in love with this naughty, naughty girl.
