Thought I already did a comment on this, check that out it has what I got to say on it. But, to be quick I like that everyone in it is happy to be involved and its a kink I have trouble finding that does not include what most people would consider less then okay even more then sleeping. The art style is pleasing enough, I suppose I'd like it longer but for what it is I'm more then happy.
Just a good sleeping hentai there, I like when I can get this kink and everybody involved is happy to be participating. Makes me feel like less of a weirdo.
