Just caught up with the thread. I was afraid the storyline with Mom in the previous update would cause a stir (because of the femdom). And it did, but for a different reason than I expected... Sorry to see it disappointed some people. Minor spoiler, I'm sure it won't please everybody (or maybe nobody), but the plan is that you'll be able to "save" her from her line of work in one of the future updates.
I'll fix the exploit in a later update. Thanks for catching that one.
As for the renders, I'll be going over them in the coming months and re-render them using my spiffy GPU. My plan is to release a 1920x1080 version of Sisterly Lust after the conversion of the old renders is completed. The scenes in the upcoming v0.7 are going to be rendered using my new hardware, so there should be a difference in quality, I hope.
I think the pool scene needs a few more renders, I'll see if I can add those when I upgrade the game to HD/Iray. MC only has sex with Riley and returns home afterwards, but I'll make that clearer in the text.
Thank you for the compliment! Sisterly Lust is still a porn game (I do realize that seducing three sisters in 12 days is quite a feat) and the characters are very much based on archetypes. But it's nice to hear that a bit of personality is coming through in my writing!
