I am home alone and I am kneeling on the bedroom floor looking at a pair of panties on the floor with a person on top of them. It's my little step brother (you). I find it very kinky that he is in my panties. I explain that you will be in a lot of trouble. But I am impressed you went through all the trouble to shrink yourself and risk being smashed around my unaware giant feet. It's sexy that you did all this just to cum in my panties. I scold and explain it is wrong to want to have sex with your step sister. I understand however that we are not actually related and I know how hot I am. I really do not blame you.
