I think, Mr Dev that you've done an exceptional job with the intensity, but also the control of the emotional aspects of your story. To my eyes at least, whilst your visuals appear, on the face of it (pardon the sort of pun there) to be the pre-eminently outstanding feature of your tale, for me the power and drive of your story lies critically in the emotions at play.
I realise this is not a particularly profound observation to be making, but I feel you're walking a tightrope here and that, as a result, the credibility of this whole setup might come tumbling down if you either overplay or underplay these profound emotional tensions which at the end of this piece have left both mother and son hopelessly in thrall to each other.
It'll be very interesting to see how, and indeed if, you are able or capable of sustaining this level of intensity going forward without burning both your story and your audience out, because over time this level of tension between the two will certainly take its toll of your audience, at least those who are here for more than merely personal gratification.
Not a fapper myself, I have found this to be an incredibly beautiful experience, for which I thank you sincerely, and I do wish you the best of luck in all that will hopefully follow. Your creation is undoubtedly, in my admittedly limited experience, one of the strongest and, even with its explicitness, most sexually tasteful and expressive VNs around right now, in terms of graphical beauty and quality and indeed outstanding emotional expression.
