Touch
The dream is always the same: Blonde woman, lips cool as ice on Gwen's skin. Long fingers playing with Gwen's raven locks, the undressing her. No words are spoken between them, for they are not necessary. It is all about their bodies entwined, hands and mouths exploring aroused flesh. A child like voice whispering sweet words in Gwen's ear. So that's how human touch feels like.
Except this creature isn't human. Humans do not sink their (fangs)teeth into your neck during their climax and suck you dry.
Then the dream is over.
Gwen fantasizes of the day they'll finally meet.
