This is one of a couple Choose-Your-Own Adventure stories, sans legitimate choices, I’ve read at Esoterotica. Good thing I don’t write out all the options, because there were an awful lot of people in the audience who had a thing for the manservant in the beginning.
Another one, set in the Edwardian era, can be found in Eso’s second anthology.
Caesar? I Hardly Know ‘er! A Choose-Ye-Owne-Adventure
by Zach B
You are a former Roman centurion named Maximus Legspreadius, and you are not a subtle man.
You awake that morning in your. . . (hut? I don’t know what Romans lived in. . .) you awake in your dwelling at the crack of dawn. You rouse Dane, your boy servant, from his sleep and order him to get you whatever Romans ate for breakfast. (A gyro?)
Anyways, you’re well in to middle-age — thirty two — and it’s been quite a while since your last roll in the hay. Metaphorically, not the pile Dane sleeps in. In your younger days, tales of your military conquests easily led to conquests of a more personal sort, though now that you’ve settled in to a stable gig as a guard at the Colosseum, women aren’t as ready to lend you their ears, let alone other sensitive organs. You’re in a slump. How do you deal with it?
To take your sexual frustrations out on Dane, who for all you know may be of legal age, turn to page 65.
To strap on armour that looks like your chest used to and head to work hoping for the sort of miracle that can only happen in a work of short erotic fiction, turn to page 23.
