His Dorothy.

In walks a stunning athletic woman with c cup breasts and a body to die for, you would guess at about 21 at the oldest clearly wearing a near replica of your costume, if not quite as revealing, but equally slutty in its own right. “What the hell is going on here, I knew you were up to something when I saw you on the dance floor. We both know you can ‘t dance.”

“Come on doll, I thought she was you at first, then she seduced me. Besides you can see how hot she is, why don’t you join us?”

“Hell yeah.” You add enthusiastically and slip on the counter impaling yourself on his cock. “Yeauch, uunngh, wow he sure is big isn’t he.” Then you sadly realize even now you are rocking slowly about working his cock into all the nooks and crannies of your bowels.

She walks forward and to your shock she simply grabs your dress and pulls it off revealing your body to the world. You look down shocked and watch her reaction as she sees what is between your legs.
