Bear in mind that this is a corruption game. As her lewd stats go up, she's less resistant to grapples and likewise grapples make her hornier. So at first, she's able to shake off pretty much everything no problem, but as the game progresses, various little missteps the player can make.. falling into an aphrodisiac pool, getting knocked down by a beefy enemy, not taking photographers seriously (they don't do damage, but every camera flash raises her exhibitionism stat a bit.. and that's a key stat, as if she has clothing damage she gains lust over time based on how exposed she is).. it all adds up.
This is only a 2 level demo, but in a full game, you'd probably have to make an effort to complete a virgin run.
edit: as for the photographers, their 2nd level animation is in the demo, but it only involves them taking upskirt shots and it seems to only be accessible if one is nearby while another enemy finishes -their- L2
