I'm disappointed Yumiya didn't show us anything between Sanae and Suwako leading up to this point, like he did with everyone else. There are literally zero Sanae/Suwako doujins that aren't threesomes with Kanako, and if Sanae got to the point where she happily took Suwako like this (and Suwako was willing as well), it must've been good.

I dunno why, but I find this particular scenario-- futa Sanae and non-futa Suwako-- much sexier than others with the residents of Moriya Shrine (like futa Suwako, futa Kanako...)
