I was able to read the 2nd part of chapter 7 without a problem so here is a summary:
Sub(forgot their names srry) joins the kendo club and dom isn't the club president anymore because he retired. The kendo club members notice they are in a relationship. Later in their dorm room dom gives sub a leash and sub rides him. When sub rides dom he goes into subspace and collapses. After they clean up. They talk about the kendo club. Dom explains that he chose the kendo club so it'd be easy for him to check on sub. Sub tells dom he doesn't want to cause trouble in the kendo club so he will work hard. At the end Dom jokes around saying if sub gets held back he'll be punished.
(That's basically all that happened I hope this helps) ╮( ̄▽ ̄)╭
