A long time ago, I wrote a short story about a sub who serves as a party decoration for her mistress, one of many posed around the room. Her outfit is a fetish Catholic school girl costume, and she envies the other subs on display who wear more exotic clothes. Even worse, she's been placed in a corner, facing the wall as if being punished, so she feels that she's missing everything. All she can do is listen to the party.
In her imagination, what's going on behind her is powerfully erotic. Every sound evokes a new scene in her mind involving one of the other subs around the room and she hopes that her turn will be next. Then a man stands behind her, out of her field of vision, and talks quietly to her. His hand slips between her thighs. He stimulates her through her white cotton panties while quietly scolding her for being so wet.
Her imagination turns to him. The voice is vaguely familiar, but which one of her mistress's friends is he? One Dom after another, she fantasies over who this man standing behind her might be. She hopes he'll spank her bottom. She wishes he'd pinch her nipples. She's aching to be fucked. The only touch he'll give her is those two fingers rubbing her clit. His rare, quiet commands strike her as the sign of a confident, difficult to please but incredibly sexy, Dom. As her imagination runs wild, she comes. It's only after he pulls down her panties and takes them with him that she realizes who he is - a guy the subs simply call the Panty Thief. No one knows much about him, or even his real name. The subs dismiss him as a loser. Certainly, he's not the physically imposing alpha male decked in leather that she'd submitted to in her fantasies.
As with Lisabet, I'm not a visual person. I don't do the pictures thing other writers seem to do. Even if I were to describe a character down to each twist of their DNA helix, people would envision someone else. Besides, I don't want to micromanage my readers that way. I trust their imagination to turn them on. And as for myself - I only warm up to people when I've met them and chatted with them a bit. Smarts and a sense of humor trump physical appearance every time. That, I write in great detail, because that's character. Eye color isn't.
