I'm not the biggest fan of Elaine's development in "Kyle's mission", the scene was hot as hell of course but never expected her to do it that early, I just feel that since she seems to be the main goal she should be the last (and the aunt first) but that's probably the case, I trust your direction, I know the final result will be great.
I'm a bigger fan of "Having Grace" development for now, since they don't know that they are related there will be less hesitation I guess, I always liked the "genetic attraction" topic, because the consequences once they find out will be interesting, also how they deal with their feelings... not to mention the foster mom is also hot, would love a mom rivalry in a future, there's a huge lack of that in porn comics.
I'm not that interested in the Shannon comic, seems to be pure corruption and I like that too but I prefer a bit of love there too, who knows... it could be the biggest surprise later.
Anyway, keep going! you are creating some great comics here, I just feel there's not much need to rush, I totally understand that subs probably ask for lewd scenes asap, but well I think that's the purpose of the short comics, the main ongoings should continue at a normal pace for now, depending on the characters, their backstory and personality.
