Ask her friend Tina to stay behind

"Oh, Tina, could you stay a moment," Becky says with all the nonchalance she can manage "There's something I'd like to discuss with you."

Tina looks a little worried at the unusual request. Becky hides a smirk at her freinds anxious expression. What could be causing it, missed homework prehaps?

"Yes Mr Trent?" She asks twisting a locke of dark hair nervously as the rest of her class files out.

"No need to worry Tina," Becky reassures her in Mr Trent's warm deep voice "You're not in any trouble I just wanted to ask you a question."

Confusion replaces worry on Tina's pretty face and Becky is a little surprised to find herself thinking of her friend as pretty. She'd known Tina was pretty of course but it's always been a remote abstract kind of awarness. Something to be admired or emulated, like a nice dress or a new hairstyle, not a thing she'd ever thought of desiring for its own sake.

Now she finds herself accutly aware of the other girl. Of her scent, of the soft inviting swell of her breasts and the shy **** way shes's looks up at her through her long lashes.

Becky feels uncomfortably warm and her heart beats faster. It's a little like the feeling she gets around a cute boy but hotter, stronger, both exciting and frightening in its sudden intensity.

A moment ago she'd simply intended to use her borrowed authority to tease her friend a little. Now, she finds she wants to do... things with her. Things that a girl shouldn't think about doing with anyone, never mind with her friend. Things that her new body seems to be loudly demanding.

Whether these sinful urges are a result of her newly revealed heritage or whether they originate with the body she currently occupies or even whether they come from some dark long suppressed corner of her own mind doesn't seem important.

The real question is, what is she going to do about them?
