I liked Cathy, but when she joined her sister and Rihanna in ridiculing and scamming me, I decided not to have anything more to do with her and her sister. Cathy's actions though, if her story was to be believed, were not as spiteful as I first thought. It sounded as though Dawn had fallen under the Zulu dominatrix's spell and Cathy was attempting to protect her sister.

Her black market business had been gobbled up by Rihanna which was probably a good thing. I wanted to tell her that she was better than that and she ought to concentrate on her studies, but her story became convoluted. Then, she let slip that she had seen me performing a routine in a semi-naked state.

That changed everything.

I had to stop Cathy from spreading what she knew. If it got around the academy, there would be a huge scandal, heads would role and the academy might even be closed down. With no funds from the film project, the education of hundreds of local girls would suffer. I planned to leave the academy at the end of the term, but I cared enough to try and stop Cathy from telling anyone what she had seen.

One way of doing that was to rekindle their friendship, something that Cathy was desperate to do. "Have you told anyone?" I asked her.

"Not a soul. I swear."

I skirted my bed and opened a drawer. "Cathy, take you panties off." I removed a skirt, panties and t-shirt, netball gear I didn't need for the time being. "It would probably be best to turn up at five o'clock just as the session finishes," I said.

Cathy released the catch on her skirt, let it drop to the floor, then pushed the blue serge panties down. "Jen, my cunt is fucking raging." She reached down and rubbed herself. "I feel like a shit asking, but is there any chance of finger fucking me before I put the clean panties on?"

"Are you serious...?"

I paused and put my hands on my hips. That was when I remembered the box in which Kerry kept her dildos. It probably only contained one, the larger one, but it might help ease the effect the hormone cream was having on Cathy.

"Um, wait a minute..."

I hurried around to the other side of Kerry's bed, dropped onto my knees and searched under the bed. I found the box I was looking for and placed it on the bed. Cathy followed me and watched as I opened it. Sure enough, only the larger dildo remained in the box. I heard my companion gasp in surprise. I too was taken aback, not by its presence, but because it was identical to the one berried in my quim!

"Wow, is that what you two use on each other?" Cathy asked.

I had to resist telling her the truth for I needed her to think that I was keen on rebuilding our friendship. "She doesn't let me touch them unless she's here." I lifted it out of the box, only to discover a four inch long key hidden beneath it. I instantly knew what it was for.

"Where's the other one?" she asked.

I thought for the moment, then made a difficult decision. "I'll explain in a minute." I picked up the key and showed Cathy how it located into a socket on the end. "The knob end is so big, the dildo could get stuck, so this key can be used to pull it out. See, once it's in the socket, you turn it to lock it. Cathy, go and put the skirt and top on."

"But what about the dildo?" I put the dildo back in the box but held onto the key. "Jen, what are you doing?" I slipped the box under the bed and held up the key.

"Cathy, I have one in my quim." She opened her mouth and then closed it. "Put your skirt and shirt on, then we'll go somewhere private."

"I get it," she said with a twinkle in her eye.

We returned to my side of the bed where she whisked her clothes off and donned the clean blue skirt and white top. I popped her dirty items in my laundry basket and grabbed the clean pair of blue serge panties along with a box of tissues.

"Come on, no one will be in the study room at this time of the day."

It was a small quiet room where we could catch up with our studies. In the past it was used for storage and cleaning equipment when the students cleaned their own dorms. The cubicles were quiet, but I couldn't risk Kerry catching me using the dildo on Cathy or someone taking a photograph of us!

The study room was empty. It was small but there was room for a proper desk and a comfortable chair. We often used the room for playing cards. We would bring in chairs and sit around the desk, drink coke and have a good laugh.

"Cor, I wish we had a room like this," Cathy said, as soon as I had closed the door and locked it.

I went to the desk and placed the panties and tissues on the surface, then held up the dildo key. "Are you okay pulling the dildo from my vagina?"

Her cheeky face lit up. "Jen, nothing would give me greater pleasure. Are you going to take your panties off?"
