stepbrother me quickly that my husband is on the phone

My husband is talking on the phone and at that moment my stepbrother and I took advantage of it to quench our thirst for lust and pleasure with the fear that he could discover us, however the desire was stronger and without planning it we resulted in a scene of sex, sweat and heat. I can't help but be hot every time my stepbrother approaches me. What would you do if you were in my situation?
