Is there smut in svsss?

I finished mdzs and tgcf, got the heads up for mdzs chps, and apparently, there isn't sex in tgcf so it was okay, but I am kinda concerned about svsss, cuz it's placed almost on the same rung as mdzs in that sense. Can someone please point out the chps, or provide a brief summary if anything pivotal happens in those?
