step-Brother takes whats his

My husband has a surprise for me, its my step-brother! He has been released early from step-son. I am so shocked, my husband has told him he can live with us for a while. The problem is, my husband doesn't know what my step-brother is like... before he went to step-son, I was owed by him, I was my step-brother's whore. I am trying everything to fight these feelings and urges now as I am a married woman, and it is so wrong, but I can't help it, he has a hold over me that I can't control... role play, step-brother, step-sister, facial, creampie, family, doggy, missionary, storyline, slow burn
