Something I think the Buffy section is in need of is more Tara centered stories. I would like to see some stories which are centered upon Tara Maclay and have her, depending upon the story type, as ether the submissive or the victim of the story. Both F/F and M/F interaction are fine but please limit any M/M slash. Also the story can be Con, Reluctant, or NonCon.
Some things I would be interested in seeing in such a story.
1. Anal sex. I rarely read about Tara taking a strap-on dildo up the butt or wearing a butt-plug.
2. Metal bondage devices such as chastity belts, scolds bridles, spreader bars, inhibitor bars, collars, cuffs, chains etc.
3. Magic sex toys. Think of all the stuff that you could do with magic to make sex toys and bondage gear more interesting.
4. Public sex, remote controlled stimulation, forced orgasm, orgasm denial, etc. Given Tara's shy nature I think such things would be interesting to see.
5. Fetishes. Costumes, uniforms, slutty clothing, diapers, latex/rubber, leather, satin, etc... use your imagination.
No need to use all of these suggestions in one story, also feel free to go beyond these items, be creative.
If you are interested in writing something like this PM me and start a thread in one of the Buffy the Vampire Slayer Fan Fiction forums so we can discuss it.
