Pet luxuriated in the hot water of the shower. He had time to contemplate what had just happened in the playroom. Mistress had told him to meet her in the study once he was cleaned up, but for once there didn't seem to be any urgency in that order. He looked down at his cock, and despite the workout it had just been through, his erection had returned. Everything he thought about these days involved sex. Cumming. Fucking. Eating cunt and ass. Sucking cock. And it kept him hard. The daily Viagra helped ensure he was pulsatingly rock hard. There was a difference in him though. He didn't even consider jerking off. His cock was hers, and cumming was entirely at her discretion.
Downstairs, Mistress and Miss were saying goodbye to the four Student Doms. They had debriefed the Doms on their performances during Pet's edging session. Finally they were reminded that they were to attend the graduation party the following week, bringing one of their most subservient male underlings with them. Only the Doms and Master would be dressed. The rest should be collared, leashed but naked.
After Mistress and Miss found themselves alone in the study, the plan for the party began in earnest. Mistress spoke.
"I think Pet can attend, initially as a butler, serving drinks and nibbles, but then as a prop for anything depraved that you wish to be performed by our students. This is your party remember, so Pet is yours to control as you desire. Master and I will simply be there to observe, and where necessary help out with the numbers. We will be assessing each student's ability to control their sub whilst exploiting them in as many sexually perverse ways as possible. But let me be quite clear, for you to graduate as a Specialist Sub you need to ensure that the acts you choreograph with the Student Doms are erotic, depraved and hard to stop watching. The whole thing will be videoed by the house cameras for debriefing. Don't hold back, but remember, cum must flow at regular occurrences for three hours, and you will only have six cocks to use. Master has said he would be happy to provide his magnificent member to assist you. And, of course, it goes without saying, we want to see squirting and orgasms from the ladies. Do you have any questions?"
Miss thought about it, then smiled.
"No. I'm all set. I've given the students all the details. They know exactly what is expected of them and their charges. I'm pretty sure this is going to be spectacular."
Mistress smiled in reply, then dismissed her.
Ten minutes later Pet rapped on the study door and was invited in by Mistress. For the first time he was invited to sit in the other chair, a large, sturdy imposing piece of furniture.
