Rin and Kaori are briefly shown having lesbian sex with each other at the start of the chapter.
The narration lets us know this was their first time both with each other, having lesbian sex in general and how much they both enjoyed it.
(Since this is about couple swapping, I’m not giving this the Cheating or Netorare tag.)
