Good babe, but this is perhaps the worst Shiashiya work yet. That this should get translated when their many, much sexier works remain only raws... I can only guess that someone's particular fetish is stroked by this work. If it was simply mother-son incest, Shiashiya's made far better than this.
My personal favourite so far is, I think, the first work of theirs I found: /g/576356/b9029e5192/ Cosplay in and of itself doesn't do that much for me, but in that work, it raises it from good to fucking stellar and that's when it's not even translated! The model, the faces, the poses, the outfits, they all resonate with me. I've considered just doing a loose translation based on a machine translation of it, but have procrastinated mainly because I'd have to mouse-draw every single character on Google Translate (the only translator I know of with a drawing tool) and the more elaborate characters can be a pain in the BUTT to find the right match. It could be that I'm being an utter rookie at this and missing out on the proper tools but I wouldn't know for a fact.
