"Costumes" by Lord Malinov (malinov@mindless.com). The author does an excellent job making the lewd and lovely, lithe and lascivious Diana seem eminently fuckable long before the real action commences. Rarely a day goes by when Diana doesn't surprise the narrator, and today she has decided to brighten their daily ambiance with a simple but tasty - er, tasteful - orgy. However, the main action occurs in her retelling of her first multiple-partner debauchery, while the narrator stimulates her to orgasm. In fact, if you are currently taking a course where you are required to report on a story that runs parallel to the Canterbury Tales, this one might be a good selection.
The tail within a tale takes place at a Halloween party during which inhibitions have disappeared and people are using sexually explicit tactile clues to guess the identities of the still-masked people. As usual at such fictional parties, a good time is had by all. The titillation of sex with known-but-unknown sexual partners is extremely well done. The author has orchestrated an orgy in a manner that would make Mark Aster and the Allen Sisters proud to participate.
