Welp, too late onii-chan. Also, because of your wishy-washy approach your childhood friend is going to get murked. She sounds like she's going over to her house after this. If you wanted to have sex with your step-sister (we ALL know you wanted to) you should have gotten her under control earlier. At least make it so 'innocent' women (yeah the childhood friend wasn't so innocent since she wanted you for herself, lol) in your general vicinity don't get stabbed.
