It's nice to see that Taylor and Krish's relationship is going well, and providing a strong link in the chain of friendships mentioned within this story. They have a very original go-to sequence of sexual activity, in terms of the couples we know from this fictional universe, adding yet more variety to the overall reading experience.
I hope now that Kat and Cassandra find they're keen to pursue their own relationship; for one thing, they will bring yet more variety to what the couples get up to within this circle of friends, which does not yet include a lesbian pair. Given Kat's views on Taylor and Krish's sex life and the roles within it, it would be interesting to know about the two girls' go-to activities. But perhaps that will have to remain one for the imagination(?).
