Inspired by all the other self-love prompts, but this OP here needs slash. So the LI is in love with the DB but the DB doesn't show any interest... or the DB and his LI are already married but the DB is off adventuring all the time... Cue lonely LI pleasuring himself to thoughts of the DB one night. Defintely wouldn't say no to the DB walking in on him and being amused/instantly turned on/confused/happy/slightly disgusted. OP has no squicks.
