The way the author uses "gaming" as a methapor for sex is genious.
We've gone through a whole arc of "cheating", making the new girl addicted to his "gaming", then the main girl trying to abstain from "gaming" cause of jealousy, only to come back to him cause "gaming" with him just feels too good for her.
These darn kids "game" way too much, sometimes even all night long!
Such debauchery!
