Ooooh! Nice. I finally have a use on this thread!
This is one of the sets from Wet Summer 2, a CG pack released some years back.
I have it uncensored, too, along with Wet Summer 1.
You won't believe me but I've scoured the internet for these, and let me tell you, you aren't going to find it anywhere. I consider myself an excellent scavenger, so trust me.
With that said, hate me if you will, but I'm going to hold Wet Summer 1 & 2 hostage until someone uploads penguinfrontier's three doujins uncensored.
So get to work, my pretties, if you want these sets. Trust me, they'll be worth it.
