[PC] Searching for video gameplay or demo of 2 titles (1 Viewer)

I'm searching for gameplay's videos (or demos) of this two titles:
Passionately Lewd Fighter Kunimaru-kun
SUMO [NTR Gangbang Game]
Obviously Google didn't help me...

 

[Sausage&Eggs]

I think those game not have any demo. dlsite usually have demo for download. Is something wrong with dlsite version of game? Seem you already find game? Or you looking to score piracy?
Sumo look pretty fun. I add to my dlsite list.

Mainly I would like to view a gameplay of those titles, because from few images and a short description I don't understand so much.
If I like those, I'll buy as I did with others.
