See Educating Cassidy - C1 - Audition and Ch2 Observe for the first parts of the story. They do lay down some of the groundwork for this chapter that will help the reader understand a few things that are going on here.
*********************************
Gwen and Cassidy arrived pretty much as expected. I had laid out the wine and set up the bedroom the way it had been for the audition. The blinds were staggered to block out most of the light but still allowed for light and even a bit of a view of the lake. It was a pretty nice view and I would normally have been out on the deck reading or grading papers while enjoying a cold beer and watching the boaters. I tried to avoid boating on the weekends, the traffic and weekend warriors out for their skiing fix were too much of a risk. I had moved the nice reading chair to a position in the corner near the foot of the bed, I figured it would provide Cassidy a better view of what was going on.
Gwen came in and after looking over the room she smiled. I was wearing the red shorts today. She was once again wearing a pair of tight leggings and this time a sports bra, her midriff bare. I don't care what the situation was, that ass in those leggings would have commanded my full attention anywhere.
"Okay, this is going to be a bit of a shock to Cassidy, but here we go!"
"Why a shock, you mean you haven't told her?"
"Oh, I explained everything, but I left a few things out. It's just a matter that she wasn't sure who you are, and I don't think she will be expecting you to be safely restrained. I've decided that I should probably restrain her as well. That way she won't get in the way. And I thought about another thing you mentioned. We can work to keep this a bit more anonymous."
"And just how do you plan on doing that?"
"Very easily!" She proceeded to fasten the restraints on me and then brought out a black stocking. Rather than putting it on, she rolled it over the top of my head. With a few adjustments, she had the thicker top part covering my hair and ears, while a thinner double layer covered my eyes. I found I could see pretty well through the layer of material, but it totally covered the top half of my face and my hair, even my ears, while leaving my mouth exposed and not blocking my nostrils.
"There, that gives you some aura of anonymity. If you can keep anything you say to a whisper, it will help. I have decided to gag you to start with, but we know that isn't going to stay in place all afternoon. Anything else before I gag you and bring her in?"
"How about a pillow under my head, so I can see a bit better?"
Gwen took a pillow and made sure it was properly placed. She placed the ball gag in my mouth and securely fastened it. She then teased my cock with her fingernails for a minute or two, just to make sure it was fully erect, not a problem as I was anticipating what was to come. "Okay, it's showtime!"
I heard two sets of footsteps coming back a minute later. I could see that Cassidy was wearing pretty much the same outfit her mother was. She was a bit smaller than her mother, but a very similar build. She was a soccer player and her legs and butt showed it. Her hair was longer and pulled into a loose ponytail. She was staring at me tied to the bed as Gwen sat her down in the chair and I heard the familiar velcro rip.
"I want you to focus on what is happening and not be distracted. Now hold still while I get your arms." I could turn my head, but my own arm was blocking some of the view. Cassidy's arms were fastened to the arms of the chair, based on the sounds, her feet probably were as well.
"Geez, mom! This is really making me uncomfortable!" Her voice was pretty similar to Gwen's, but a bit softer and slightly higher pitch. Gwen's had a sultry timbre to it that I liked.
"Uncomfortable as in emotionally scarring or is your body reacting to the stimulus?"
"Well, I'm getting pretty excited!" as she wiggled in the chair.
"Okay, that is perfectly natural. So let's get to it! The first thing to realize is that it is pretty easy to tell whether a man is sexually excited. They have a very difficult time trying to conceal it. I'm sure you've noticed some of the boys in your classes waiting until the room has emptied before they go to leave, and are holding their backpack in front of them rather than throwing it over their shoulder. See what I mean?" I was serving as a good example, my cock was at full size, creating a tent in the boxers. I was at full extent, each beat of my heart causing it to jiggle with excitement. A few more beats and it was going to pop right through the fly and into the open air.
Gwen flicked it lightly with her finger, just hard enough to cause me to yelp into the gag and my cock to slide out of the satin confines.
