Towel gets stuck

Hermione Jean Potter the lovely wife of Harry James Potter was taking a shower. Harry was with his grandma Walburga Potter, Hermione didnt think Harry's grandmother would like her Possibility Walburga says Hermione would be her muggle born counter part. Even Lily Evans Potter agrees with her, Hermione wrapped an towel around herself like her mother in law and grandmother in law Hermione had a nice body. Hermione and Harry lived in the Grimmauld Place while Walburga lived with James and Lily, Sirius hated being in the same house of his mum, which James decided to throw his big brother out since he and Regulus are trying to make them Reconcile but it failed Walburga knew what her two younger children were doing.
