Sexual Empathy

Ally was a late bloomer as far as sexual awareness went. A friend has to give her instruction in self-pleasuring. And even then, she never developed a sexual identity by the time she reached college age. Sometime during her journey from puberty to adulthood, Ally learned by chance that she has a power unlike anyone in the world. The power caused her confusion and self-doubt at first. But once she got a handle on what the power was, she was able to assume unlimited identities that exist only in other people's fantasies.
With her new power under control, Ally proceeded to undertake a quest to provide the most pleasure to the most people. She first sought out her closest friends and as her confidence grew, she became aware her strange sexual power was limitless.
