Alisa probably wasn't a succubus, but she'd been overwhelmingly sexually active (bordering on slutty) even before she cottoned on to her sister's desires. And getting casually fucked almost every day had done a lot to erode Alisa's shame. So she was "just" oversexed - only a problem if Harbin didn't fuck her so regularly.

Alisa did both at once, closing her eyes as she reached under her skirt to peel off her sodden panties. Harbin would quickly find at the front of Alisa's mind that the series in question did have an anime, giving her plenty to work with if she planned to copy a voice or personality. Despite Alisa's memories focusing a lot on T&A, though, the series itself seemed quite chaste. Plenty of wiggle room when it came to fantasies, in other words.
