Master
I ran my hand through Pippa's hair. "Last night you volunteered for various degrading things, you had a fair amount to drink."
"Yes Master, I did and I had."
"That is fine, Pippa, are you of the same mind?"
"I don't know Master, I don't want to do it but the thought of it makes my stomach flutter, I am becoming moist now at the idea. I am dreading doing it, it's disgusting and I want to do it because it is disgusting."
"Well"
"Yes Master, I want to do it." She was crying.
"I want to help her, please Master." said Emily.
"Is that alright with you Pippa?" I asked.
"Yes."
"Emily fetch two suppositories from the bathroom." I ordered. She returned with them. "Pippa, bend over." She bent with her legs spread, I put the first suppository into her pussy to lubricate it and pushed it into her arse as high as I could. I repeated the second one.
"Okay you can sit down and hold it in until you cannot hold it, when you have cleared your bowels, have a shower." I left the room.
This was it, never threaten to do something that you can't carry out. I just wanted to get in her head, to show her total humiliation.
Emily and Pippa came in. "Pippa bend over the bench. Emily put this in Pippa and squat next to her." I handed her some lube which she squirted into Pippa's arse. "Now suck my cock."
