First Time (Eternal Dungeon #1.3)
Dusk Peterson

One man seeks to heal from abuse. The other man dreams of abusing. Now they're in love.
As the Eternal Dungeon's chief torturer and the dungeon's newest member strive to find a middle ground on which they can meet, their lovemaking forces Layle Smith to return in his mind to an older dungeon he had long abandoned. In that dungeon lies a helpless prisoner . . . yet perhaps the prisoner is not quite so helpless as he appears.
This suspenseful novelette (miniature novel) can be read on its own or as the third story in the "Rebirth" volume of The Eternal Dungeon, an award-winning speculative fiction series set in a nineteenth-century prison where the psychologists wield whips. Friendship, family, gay love, and rebellion are intertwining plotlines in the series.
