Kancolle(?) Onsen Sex MMD Video

I saw an MMD video a while ago that had this girl dancing in a bath or onsen with a few other girls watching her. Partway through the video a bunch of dudes (the standard Sin Sack model I believe) come in, the camera cutting outside the room to show another girl collecting payments from them. I'm pretty sure one of the girls who was watching the main dancing girl sucks one of the guys off. The men surround the main dancing girl towards the end of the song, fucking her either right at the end or in a mini-scene after the song initially ends. I've googled about 30 variations of "MMD Onsen Orgy" to no avail, and this image is the closest I've come to what might be the video I remember. Even if it's not, I'd like to verify for sure that it's something different.
