Can't find two stand-alone stories

Hello everyone,

I have been trying to find two stand-alone stories, written by two different authors for several weeks, but have so far drawn a blank. Unfortunately I can't remember either author names or titles, but I hope someone will recognise my descriptions:

1. About a boy attending school in a magical-fantasy version of England (dragons attacks mentioned), who is changed every day by the school bully in some embarrassing way. At the end of each day he is changed back, but has his genitalia changed to female for the entire summer holiday.

2. Set in a major Australian city, a M2F who is into motorbikes meets an understanding / accepting male bike mechanic. Both are unhappy about treatment from the local all-female bike gang.

Any leads would be much appreciated.

Regards,
