It's fun to do this with my stepsister every day

Today everyone was on vacation except me and my lazy stepsister went on vacation, we were just the two of us at home. Every day we never just go out to hang out or go for a walk. We just like to stay at home, but when no one is home I do this relationship with my stepsister every day. Even if there are people at home, we still do it at night when everyone is resting.
