Mẹ kế của tôi rất nóng bỏng, cô ấy thích ngửi con cu của tôi

One day I discovered my stepmom smelling my dirty underwear, at first it seemed strange to me but then I thought it was normal, since she's a stepmom, I noticed that she did it often so one day I asked her if she wanted to smell the ones she was already wearing, omg said yes
