First batch from DLsite’s 2020 Summer Sale. There are going to be quite a few of these.

So far there was only one upload of Cream Gallon. That’s a shame so I wrapped up the real discount ones.
I have to admit, I have no idea what initial release bonus they're talking about.

EDIT: A nice user named genl provided me with the actual bonus. They apparently had it for the duration of the initial sale and while they corrected the title on the listing they did not bother to do the same on the actual product. Go figure. So hey, it's in now. Thanks man!

Is it possible for you to get 凛とした金髪ツインテール少女が性玩具に成り果てるまで as well?
