After watching her wiggle into that tiny piece of cloth, Ana again spread her legs and showed her nice crotch to me.Her shaven slit was easily seen th...ough the thin material. I patted her pussy lips and wished her good luck at the mall…Anita smiled, saying I would have later for supper a nice freshly fucked pussy. I then asked to who lucky bastard’s semen I would be eating tonight; but Ana just laughed, saying it would be a nice surprise for me.The rest of the day at the office, I could not. I was still playing possum pretending my actions were independent of anything Anita was doing. I used long slow strokes. I was encouraged when she started rubbing the area just under her breasts. This wasn't the u*********s movements of a sleeping person, but the deliberate self stimulation of a horny woman. I still was unsure of this game. True, the exhibitionist in me wanted her to watch me beat off. The voyeur in me wanted to watch her stroke to climax. What if I was wrong and she was. I just nodded.She moved closer, confronted with a mirror image of herself without knowing how to handle it. I just looked back at her recalling both how beautiful she was, and how incongruous the huge penis she now sported looked on her. One fact was inescapable though - we were twins. Total carbon copies of each other.We hugged for ages, drawing strength from each other. Me still shell-shocked about my transformation, and her desperately looking for me to comfort her. She wanted my traditional. "Are you coming Mike?" Oh yeah, sure Jennie. So what happened to you that was so unusual?"Mike caught up and then matched his stride with hers. He was expecting her to tell him something like she flunked an exam or something like that.Something a girl would think of as being really unusual. He knew she was a good student, and probably had never seen a grade lower than a B in her life."Let's see. Well I flashed a look at my panties to a guy in History, practically put an eye out with my boob in.
