She becomes a sissy femtrap

As your sister was moaning from her pervious orgasm, she felt something more pleasure inducing as she felt a little bump where her cunt used to be. She felt the bump start to grow and grow until it had become a penis. What was going on she thought. Had her envy of her brothers predicament done something to her.

She then felt her penis get cold as she looked at it to she a big metal chastity cage on it.

Oh great can this get any worse she thought
