Branching off of that suggestion (which I support, by the way), I came up with an idea for another talent for succubi, who are rather noticeably lacking in talent variety.
*Sexual Tyrannosaurus: Each time the character has an orgasm or causes another character an orgasm (or upon the first successful use of Deny Release/Self Control succubus magic with a single partner), they temporarily gain a +4 Resistance bonus and a +6 PP damage bonus until they next rest. This stacks up to 5 times in a single day.
