I'm also the kind that likes to see everything but I also get that there needs to be some incentive to a virgin run and skipping your own scenes. Most would see the virgin run as reward enough but some might not.
An alternative to some could be ingame social media. A computer or phone you can use and perhaps some scenes get uploaded, like the planned dance event scenes. Then you could also add a bunch of online content later if you felt like it. Scenes involving other characters you can stumble across online, an online character that you might get to meet, or developing an online presence yourself posting selfies or lewd streaming.
