Lia doesn't know it yet, but something has changed. An invisible connection, a mysterious link, has been established between her body and a stranger's app. Settling in a discreet corner of a dimly lit café, her friend has left her behind... but another "user" has been waiting for her for a long time. He doesn't touch her. He doesn't speak to her. And yet, through an unsuspected technology, he slowly invites himself into her intimate space. A shiver runs through her skin. Her thighs tighten instinctively. Something inexplicable is awakening... and she doesn't even know why. Her breathing quickens as her gaze remains fixed on her phone. A simple vibration, a message from no sender. And suddenly, her body responds. Her senses awaken. She is alone. But she isn't really alone anymore.
