Trying on panties for my stepbrother-in-law (with Claire Heart)

Claire is having some problems with her income right now, but you are kind enough to let her stay with you in your home. She is your step-sister-in-law and you would never have thought not to let her stay there. Claire expresses sadness that her step-sister isn't taking such good care of herself and that she is gaining some weight. You have a gift for Claire, so she follows you to the bedroom. You bought some panties for your wife, but now that she has gained weight, they will not fit on her. You might as well give them to Claire. You know that she will be able to wear them. She is grateful and she decides to try on a few of them just for you. This is even more than you would have expected. She first tries on the blue boy shorts and they fit her just right. She shimmies on the next pair and she instantly loves how silky they feel on her body. Next she puts on the tiny thong.
