Well, that's the term that snap to my mind at the time XD
In hindsight though, a lot of games have that system with their magic (like Teto, where your spells increase your lust where at max bar you turn horny, in case of Saki your Int increase with more sex. Or an oddball example

where they're just women with magic power and also are sluts)
Then in that Sugar Star's upcoming game, the swordgirl transform when she's raped, because her sentient sword gain power that way and take over when that happen, which the girl does comment she really don't enjoy that succubus-like style of thing at all. So she's not really magical slut, but more like succubus-possesssed swordswoman? (where she can win either by normal means or getting raped and have the magic sword clean up)
