Tristan, a slightly-built young man, is introduced into the world of crossdressing and wildly erotic sex with males, females, and she-males by his mentor, Vivian. Following Vivian's instructions, Tristan soon finds himself dressed in ultra-feminine outfits of silk, satin, and lace and looking for all the world like a beautiful young woman. As Tristy, the young man finds himself on all fours, servicing Vivian along with her friends, both male and female. Not that Tristan/Tristy minds being the object of intense sexual desire by all who behold him/her. The story culminates with one of the wildest orgies ever committed to print, set in an elaborate sexual playground inside a palatial mansion, involving people of all genders and sexual persuasions with Tristan (now sporting hormone-enhanced breasts) at the center of the action.
