OMG caught by stepbrother fucking dildo

In this heat, my thoughts constantly revolve around fucking. Unfortunately, there’s no cock nearby, or at least I thought so. I completely forgot that my horny stepbrother was in the next room. But while I was fucking him with the dildo and moaning loudly, he must have heard me. Suddenly the door opened… Did I go too far? How would you have reacted in that situation?
