My step-SISTER hasn't been making nearly enough doing her usual social media influencing and finds an interesting opportunity online.. The ad is offering $5000 to make a porn with a sibling. They are also offering $5000 more for a creampie. She pitches the idea to me, and at first I am completely against it. Eventually I decide to help her. We have to introduce ourselves, and complete a list of actions. Tongue kissing, undressing each other, touching each other's bodies, perform oral sex on each other, and eventually UNPROTECTED sex. After suffering through doing all of these things with my step-SISTER, we decide that we have already gone this far, why not get the extra $5000 for the creampie. What have we done?
