(lol cool, I accidentally wrote it in first person. I might change it or I might keep it this way. Let me know what you guys think) (Also, don't be afraid to tell me what you'd like to see included in the upcoming chapters! I love new ideas (: )

The next day at school, the first thing I did was go to the nurses office, me not being able to handle what Mistress was doing to me any longer. I peeked through the doors to see if she was there, thankfully she was. I then placed my hand on the door handle and turned it, opening the door. She glanced up from her paperwork and at me before continuing what she was doing.

"Hey Vanity, how's your situation going?" She smiled friendly, seeming to not know about what Mistress had said she would tell her. I sighed a bit in relief.

"It's no going too well, so I'm going to need the key back, Sensei." I walked closer to her desk and held my hand out, expecting it to be given to me. She chuckled a bit and stood up, placing her hands on her desk and leaning forward, her voluptuous breasts squished together while her face was so close to mine i could smell the shampoo that radiated off of her hair.

She placed a hand on the buttons of her uniform, undoing a couple of them to expose cleavage, her pink, lacy bra poking through while her breasts seemed to be gushing out. My eyes were drawn to them before she giggled, grabbing my attention. My cheeks flared up red from me being so perverse and especially because I wasn't even being sly about it. "I'll give you the key back at the end of next week but from now on in the mornings, you come to me first thing. Understood?" Her voice was so mesmerizing it sounded how silk would feel.

I nodded my head, thoughts of all kinds storming through it.'She didn't seem to know about what Mistress had said, this has to be her own little game then.'

What broked me from my thoughts was her walking away from me and towards her door, locking it before turning the lights out. "Follow me." She smirked as she grabbed my hand, forcing me through another door which lead to the mattresses you'd lay on if you weren't feeling well. I sat down on one of them, primarily because she had pushed me onto it.

"Ah… Sensei, what are you doing?" She was rummaging through her cabinets, getting out syringes and some medicine it seemed.

Totally disregarding my question, she told me to strip off my clothes then lay down, which I ended up doing. She strutted over with all the items she needed on a tray, sitting on the bed next to me.

I took off my shirt, my breasts falling out, due to the lack of no bra then slid my skirt off of my thick thighs, exposing myself in front of her completely. I then laid down as she gave me a surprised look.

"You've become a bit of a slut since you've been wearing this thing, haven't you? No bra… No panties…" She chuckled as she moved the cock cage around. I was too embarrassed to respond and I couldn't exactly tell her about my Mistress so I just nodded my head in response. She then opened up an alcohol wipe and wiped down the side of my breast, near my areola, grabbing the full syringe and injecting me with whatever was in it. She did the same to the other breast as well.

"I think you'll like this a lot. This serum will cause your breasts to not only grow, but also become more sensitive. Soon, just the feeling of the material of your shirt rubbing against them will almost be enough for you to cum. You should notice a tremendous difference in cup size with in a couple days." She had to let out a charming yet seductive laugh after what she said, making it not seem as bad as it was.

My cock had been throbbing through the tiny little cage it was trapped in, being able to reach a climax but not actually get to cum was complete torture for me.

She moved the tray and stood up, then started to unbutton more of her outfit than before until it was completely off and she was nearly undressed fully. I sat up and ogled her body, my eyes trying to grasp every curve of her and how she looked so perfect. Her bra was a hot pink color which had a lacy trim around it, clearly a push up bra but sexy nonetheless. Her panties matched and they were completely see through. they cupped her bouncy cheeks, somewhat going in like a thong but not entirely.

"Ever since I found out about your…" She hesitated then looked back at me, seeming to admire my body, then a small smirk on her face appeared again. "disorder. You intrigued me. I immediately wanted to poke and prod at you."

Her heels clicked against the tile as she turned towards me, pushing me back onto the mattress before straddling over top of me. Her sea foam green eyes grazing at my body just as her finger tips started doing. Strands of her hair cupped around her face, framing it while the rest landed down her back per usual. It was only seconds when her fingers became infatuated with my nipples, gliding over them and tugging at them in an upwards motion. Moans threatening to pour out past my lips.

"Besides," She released my hard buds and ran her hands down my body until she reached her thighs, going up her own body then stopped underneath her bra. "The way you look at me doesn't go unnoticed. I can see the lust in your eyes each time I talk to you or even walk by." She moved her hands behind her back, unhooking her bra before discarding it to the tile. My face turned a dark shade of red, embarrassed that she had caught me so many times and flustered that she let me do it out of her own enjoyment. Who would have guessed she has exhibitionist tendencies?

Her breasts were perky and her pert nipples matched the perfection of her entire body, they were exactly what I had imagined them to look like. I reached my hands up hesitantly before going ahead and getting them in my grasp. They were soft just as I had hoped they were too.

She chuckled a bit as she smacked my hands away, leaning forward and putting her hands against the wall, her breasts pressed up against my face. "If you're going to play with them, do it right. Use your mouth and your hands."

My reaction to what she had asked of me was immediate. My hands trailed up from her waist to her breasts, I tenderly nibbled on her skin while my hands played with her breasts aggressively, tugging and pulling on her nipples while my ears listened to the sounds if pleasure run out of her mouth.

I pressed her breasts together and placed both hard buds inside my mouth, biting and sucking on them simultaneously. I would glance up every now and again to see her blushing face, mouth wide open as she panted and moaned from what she was getting from me.

It was so much different touching her compared to my Mistress. Mistress is strict and rough while she's more gentle and seductive.

After a while of toying with her breasts, she stopped leaning against the wall and made her way down my body, stopping at my breasts as she massaged them, I almost instantly arched my back and gasped from how sensitive the serum had made my nipples. I grabbed onto the sides of the mattress and held back a lot of my moans, not wanting to be loud That task was becoming harder and harder to do with how the palm of her hand would glide against my hard buds.

She reached one hand down to my sopping wet pussy and started rubbing it gently before dipping two fingers in, curling them a bit and ramming them into my sweet spot. I groaned from feeling my cock trying to get hard but my cage not allowing it.

Soon, it all came to an abrupt stop due to the phone ringing. She whined a bit as she then sighed, slowly taking her fingers out of me and lapping up the mess I made on her hand. She grabbed her bra and put it on along with the rest of her clothes.

Meanwhile, I'm panting from the experience, my body sensitive from the sensation she had just gave me. I whimpered a bit as I turned my head to the side, reaching down to my cock cage and fiddling with it.

"Please, give me the key so I can remove this. It hurts so much and I-I'd really like to cum now." I sat up and looked at her with a pout, my cheeks red from the pleasure she had given me and from the embarrassment of asking such a question.

All she did was give a giggle for a response, "Put your clothes on and go to class or else you'll be late." She then walked out of the room and went to answer the phone call.

I looked at the time and noticed I had about five minutes to make it to class before I got docked for a tardy. I slipped my skirt on, my pussy juice sliding down my inner thighs and threw on my top. My nipples so hard they were poking out like headlights. My face grew dark as I went ahead and made my way to class, holding my book bag against my chest so it wasn't completely obvious. Before i left I had made eye contact with her, she winked at me with that cute smile on her face.

I was able to make it to class on time before Mistress came in, which was a relief. 'Only God knows how she'd punish me if she found out what i was doing with the school nurse…'

At one point in class, my pencil rolled off my desk and as I leaned down to get it, I could feel my nipples brush against the material, making me shiver and gasp. I had received a few looks from the people surrounding me, but disregarded them as if they never happened.

The entire time during the class, I was daydreaming of what else would have happened if that damned phone hadn't rang. My pussy had been throbbing all the way until lunch because I couldn't get it off my mind.

Once lunch time had arrived I grabbed my bento box and went up to the roof as normal and ate up there. My breasts bouncing and rubbing against my shirt as I went up the stairs to the roof, becoming hard again. I opened the door and listened to it slam shut while I sat down in my usual spot. I set the bento down beside me and lifted up my shirt, gasping a bit as I did so. My cheeks flushed a bright red color as I looked out passed the fence on the roof. People hanging out in the courtyard, eating their meals while I sat up on the roof orgasm deprived.

I grabbed my bento box and began eating it, the breeze of the outside against my nipples giving me a chill now and again. 'Still better than having a constant pleasure while I eat I suppose…'

Once I was done eating, which didn't take long, I set the bento back down next to me, biting my lip as I stared down at my still exposed breasts. I moved my hands up to them grabbed them roughly, massaging them against my body while I flicked my thumb back and forth against my nipples. I starting having shorter breaths as I went into a daze, my pussy throbbing for attention so I dipped a hand under my skirt as well after placing one of my feet up on the bench next to me. I curled my fingers the way the school nurse had done and continuously hit my spot. My juices were spilling out and dripping onto the bench creating a wet spot beneath me.

Towards the end of lunch, I realized that people were starting to head back to class and I whimpered, fixing myself up and grabbing my thing as I made my way back too.

'I know touching myself while I'm in a position like this doesn't help anything but I can't help it. It all feels so good. Almost as good as just not cumming, I'm in a perpetual state of pleasure and I can't get enough of it.'

The end of the day, soon came to an end. Once everyone left the class, I stayed after like my Mistress told me to. I walked up to her desk and she leaned in with a sly smirk, her hands folded and under her chin to support her head.

"I've got a present for you, my little slut."
