It's a quite recent one, I mean I don't now exactly about it, but it was top doujins on the site like last month.
Story: There's a guy tormented by an evil spirit, so there's three sisters trying to help him exorcise it by having sax with him. They're three priestess sisters apparently, there's the big one, the middle one and the small one.
Turns out in last pages he goes berserker on the small one, the other sisters try to call help but in the end it seems the guy is more hurt from this than the youngest sister…
