They take it in their stride

"So Danny," Dad said, breaking the silence "What are you planning to do with the rest of the day?"

"I've got a raid planned in WOW later," Danny said around a mouthful of mash potato "but first I'm going to fuck mom's ass."

I gasped expecting Danny's crude announcement to cause an explosion but Mom just stared at her plate a pink blush colouring her cheeks.

"Ha, good choice, she's got a great ass," Dad laughed "of course she's never let me do it, not even on our honeymoon, but it's not like she can say no to you son."

I couldn't believe what I was hearing. Yet, at the same time I knew they were right. Dan could do whatever he wanted with mom, with any of us. Because, because…? Well, I couldn't exactly say why but I knew deep in my heart that it was so.

While I tried to reconcile my existential crisis Dad was still talking.

"How about you Brad?" He asked my big brother

"I thought I'd blow a load in the twins before I head home." Brad said casually "Between Kelly's baby hormones and work I haven't been getting much recently."

This was too much, the idea of Brad betraying his pregnant wife with his own sisters shocked me into speaking before thinking.

"Oh my God," I blurted out "that's disgusting Brad. How can you even think about that?"

Even as I said it I knew I'd made a terrible mistake. What right did I have to tell Brad what to do? I squirmed under the shocked expression of my family feeling like I'd suggested serving roasted puppies.

As much as I knew I was in the wrong a stubborn part of me knew I was right to stand my ground.
