Sibling Rivalry: Can a Threesome Fix Their Broken Bond?

My stepdad actually thought I could play therapist with my screwed-up stepsiblings. Yeah, right. They were at each other's throats 24/7, and he dumps the whole mess on me. Fine. I was ready to do whatever the fuck it took to shut them up. I tried the "nice conversation" thing, and it blew up in two seconds flat. But that's when it hit me. I finally saw the real problem. They don't hate each other, they just want to fuck each other's brains out! All that sexual energy was ready to explode. The solution was obvious and so much dirtier than family therapy. We just needed to get it all out of their system with one wild, hardcore, raw threesome.
