Ok, art is really great, and as for the story, it's intriguing...
now with scenari... I played R1 first then the original - and i prefer - by far the original.
In the 1st story, MC is being used in a twisted way by Victoria, to help Audrey get over her lack of self confidence and virginity with the MC which is displayed as the guy she loves !
In the rewrite, Victoria wittingly fucks the MC right before Audrey's eyes, Audrey being in love with MC (or so we're led to understand), and knowing she would't throw her virginity away - also knowing it only was a question of minutes before she discovered everything. I believe that to be one of the worst case of betrayal ever. If the aim was for Victoria to be hated, well it worked.
Remains me of an apalling - and horrible horror movie - "A Serbian Film" in which the MC (a pornstar) fucks his kid (who also has a bag on his head) , seconds before knowing it, while his friend fucks the MC's wife right next to him - evrything being taped for a movie.
So yep - if we exclude sex (since it's a sex game) I'd still choose wicked twisted friendship over worst betrayal ever
