I immediately took the rope from her hand, pulled her arms behind her, and tied her hands together with one end of it. I pulled her shorts and pantie... off and stuffed the panties in her mouth.“Keep this in your mouth until I tell you otherwise. If they fall out, you will be punished.”She was looking at me this whole time with a mix of excitement and fear. I could tell this was something she had fantasized about, but had probably never done before. I reached down and felt her pussy – it was. How is mom?" I asked."She is alright...she has already boarded the bus and I thought that I should check up on you before I got on it too." He replied."What are you going to do for the rest of the evening?" he asked."Haven't made any plans...but I think I will go out with friends." I replied."Hmmm...you inform me where and with whom you are going before leaving. You are going to send me the cell numbers of the friends you are going with. Is that understood?" He said, sounding like a drill. Of course, I have plenty of notice when this is going to happen so I'm able to plan in advance what I'm going to do when I'm alone. Usually I'm left a short list of things she wants done, and once that's fulfilled the rest of the time is my own.These trips are very useful to me because I normally have to fit my 'hobby' of making solo porn videos into a few hours when my wife is out of the house. Preparation, set-up, & tiding away time eat into those precious hours so time spent 'performing' in. At least the school allowed her to leave her loft there. I'm glad I didn't have to haul that also. The big day arrived, Maria and Gwen climbed into the front seat of the car. I was okay with that, it meant I could sleep on the back seat. The six hour drive passed quickly. When we arrived, Gwen and Maria disappeared, only to return a half hour later. Gwen and her old roommate had previously reserved their old room, and it was ready them to move into. After lugging all Gwen's belongings to her.
