Isabelle and Cy's sex life kind of changes with the seasons due to both the academic schedule and Isabelle's physical responses to the weather changing. Because school is busier before winter break and because the cold really exacerbates the pain she experiences from old injuries, she and Cy tend to taper off during finals season, and then the sex they have over Christmas break is more plentiful but more vanilla. It's not until the weather warms up and school eases that Cy finally starts delivering on all of Isabelle's begging for pain. They get the majority of their hardcore kinky fucking done over summer break and are more laidback the rest of the time. Of course, Lynn is always and forever Cy's main squeeze, so Isabelle has to get her fuck appointments in around Lynn's schedule.

As for aftercare, Isabelle is a cuddler! Cy typically holds her until she comes down emotionally, then gives her a shower and bundles her up for Yet More Cuddling and restorative things like water, juice, snacks, etc. Isabelle likes being sort of littlespace-adjacent for aftercare sometimes, so Cy has learned to indulge her with particular childhood movies and stuffed animals. Isabelle craves affection after sex, and he doesn't mind offering that.
