***I took control back from Ashley and curled up into a ball. Icould feel a change building up in me and I knew I wanted it tohappen. Ashley was part ...of my mind, my sex drive. She had gottenso powerful with her one single goal. Fuck everything that moved.And I knew her persona was growing in mine. I felt so weakcompared to her. I started to sob. But I stopped when I realizedhow stupid it was to cry about this. I loved being a woman!And with that thought, my transformation began. I moaned. She shakes her head and turns her back towards me.I look at her ass again. It beckons me and I slip the tip of my cock just past her cheeks. She slaps it away and walks over to the bed, absent-mindedly bending over to reveal a pair of pouty lips between her legs.‘I told you I hate those things,’ she says into the phone. ‘How’d you like an electric collar around your neck.’A laugh suddenly escapes from her. A private joke between them. I feel a twinge of jealousy for a second but I know he’ll. Betty looked like she was going to argue the point, but then she just said, "OK, Sarah."They got dressed and went to their classes. That night, Sarah visited with Betty to find out how she felt about the previous night's activities. She discovered that Betty would be quite happy to do it again any night, over and over, though she'd prefer that Sarah were there, too.After the events of the birthday, Sarah's questions of bisexuality pretty much disappeared. Only a few days later, during another. I was on a mission to relieve my tension.I was thrilled to find all the stalls empty when I entered. I immediately headed for the last stall for the most privacy possible. I didn’t waste any time getting started, hoping to finish before someone else came in. While leaning against the back wall, I bunched my skirt up around my waist and started aggressively rubbing my clit through my soaked panties. I bit my lower lip to keep from moaning in pleasure.Listening quickly to make sure no one else.
