Frustration

It had been three weeks since Matthew swap bodies with his sister and with no idea how it happened they had no way of knowing how to undo it.

Matthew lent on the bathroom door and said to his sister if you think I'm going to do anything in your body you can watch me take a shower?

Whilst he secretly prayed she would not as he was desperate to get some alone time with her body.

He was not happy with the idea of masturbating in his sister's body but he was so horny just putting on his knickers made him wet.

He thought it might have had something to do with his hormones being up and down after his first period and with his sister and his mother always watching him he was hoping he could play with himself in the shower to relieve the buildup of tension & sexual frustration without anybody knowing.

But no matter where he went his sister followed him and after 3 weeks it was getting on his nerves but luckily his sister declined his offer but told him she would be listening for science of anything out of order as she watched him close the bathroom door.
