Not so tough now.

Michelle could not take it anymore and decided to give her boyfriend Mat a taste of his own medicine and show him what it was like to be his girlfriend.

So after lacing his beer with half the formula and drinking the other half herself they swapped bodies in the night which really pissed off Mat upon awakening and discovering what she had done to him especially seeing he could do nothing about it now that he no longer had his strong male body to intimidate her with.

So he just had to put up with it and let her have her fun like letting her try out sex from the man's point of view and let her just bend him over the counter and take him from behind with his own cock whilst telling him:

Just to remind him of his new position in their relationship.
