"What effect does it bring?"
"I get excited, Miss. And ... it arouses me?" her voice was at a whisper with her embarrassment.
"It excites and arouses you." I repeated in a much louder voice. Now even coral was blushing and looking nervous. "Could you please demonstrate for us," I said, passing the shiny humming toy to her. She took it from my hand and then looked confused. "Not on yourself but on pet sheba." I gestured to the girl lying before us.
"On ... Miss?"
"Yes, on pet sheba. Show the room the wonders that can come from using such a toy. If you can make her cum then I promise you will be rewarded. Now, do your best."
She was a little nervous but still eager to please as she dropped to her knees beside pet sheba. Without hesitation she reached out and let the tip of the vibrator rest on sheba's mound. The girl whimpered but, as coral started to move the toy around her whimpers began to turn into moans. Sadly, she also clamped the thighs together even more tightly. I beckoned marisla forward and quietly spoke to her.
"I want you to kneel at sheba's feet and spread her feet as far apart as you can. We want coral to get to as much of sheba's cunt as possible."
Grateful to only be playing a minor role she did as she was told at once. It was a struggle as sheba resisted as best as she could but marisla was stronger that she looked. Slowly the feet and then the legs were pushed into a wide vee. I leaned down and spoke quietly into marisla's ear.
"Shuffle forward to get between her legs. Then maybe lift her knees and use them to make her gape wider still."
Meanwhile, coral was already exploring the full extent of sheba's now gaping and very wet pussy and sheba's moans were becoming louder. I could tell she was not far off, and that coral was an expert at what she was doing. I watched as she slipped the tip of the toy inside sheba's pussy. It went in easily with the help of nature's lube that was spilling out of sheba's pussy and making a dark patch on the carpet. The toy went even deeper, and the moans became louder until, suddenly they turned into a sort of shriek and sheba's body convulsed as her orgasm hit. Her cum squirted past the plug of the vibrator and splashed across the floor. Coral looked up at me and grinned. Slowly she pulled the shiny phallus out and raised it to her lips and tasted the other girl's cum. Her tongue carefully cleaned the toy. I leaned down and spoke in her ear.
"Well done, pet coral. Now, time for your reward. Kneel either side of her head and let your pussy rest on her mouth. She should know to be grateful. Keep the toy on her clit. Maybe she can have another orgasm."
I moved and knelt next to marisla who was still holding sheba's knees apart although this was no longer necessary and there was a willingness on sheba's part to keep them spread. I put a hand behind marisla's head and pushed forward gently. She turned her head and looked at me with alarm when she realised what I was making her do. her eyes were pleading with me.
"Miss Laura ... I've ... I've never ... with a girl, Miss."
"Well, no time like the present," I told her pushing her further down and forward.
She knew that resistance would be futile and might result in a punishment of some sort, so she reluctantly allowed me to press her face into sheba's soaking and oozing pussy.
"Fingers and tongue, marisla, help coral make her cum again."
I shuffled back and then sat, leaning against the wall. Tansy dropped to sit beside me and together we watched the group at play.
"I must admit," said Tansy quietly, "I am a little jealous. What wouldn't I give to be the one lying there being served and also serving."
"I'm sure we'll have plenty of opportunity to enjoy such things in the days to come. If you have any ideas on their training, please let me know. You are my assistant and my equal in this."
The tableau before us was beginning to become more animated. Pet sheba was starting to thrash wildly under the ministrations of the vibrator and marisla's newly found vigour with her tongue and lips. I could also see her fingers sliding in and out as she finger-fucked the cunt under her care. There was a muffled scream from sheba as she came for a second time and Tansy and I giggled as she squirted almost violently. Spray showered to all corners. I even felt some land on my legs, and I was six feet away.
Then, to top it all, I saw coral tense up. Her back arched and stiffened pushing her small but pert tits up. She let out a long and very loud, "AAAAAAAAAA" almost a scream as she came, leaking her cum all over sheba's face. To be fair she didn't stop her work as I could see her jaw working between coral's thighs. She was obviously drinking in as much of coral's juices as she could. Coral slowly softened and she collapsed forward to lie across sheba with her head next to marisla's. I looked at Tansy and smiled with a satisfied pleasure. My first experiment at teaching trainees had gone better than I had expected. In addition the mosaic of three sweaty bodies entangled together, two black and one white, was a beautiful sight, one of the best I had ever seen.
