The heroine actually resisted and managed to delete the blackmail and is willing to tell her BF about what happened?
Sounds like bait to me. But it would be a first that the girlfriend actually overturns her situation.

Seems like there will be a part 2 to this story.

The BF knows something is up and she's disheveled and a mess, not to mention that she has cum running down her leg. If this ends up going with the typical netorare ending, then it's best to stop here. The blackmail set up and her not having sex since it was her first time is a big setup to the type of ending we know will happen. She'll either blame him for what happened, he'll be into cuckoldry or he'll apologize and they make up but she'll go back to the guy since her first time was with him and the BF will probably have a small dick.
