DAY 26Stepmom come Stepson for stay at night and got rough sex in share bed

DAY 26 - I quarreled with my husband because I constantly think about a threesome, and I remembered how he fucked me with my stepson. We had a fight and I had to come to my stepson and stay the night. Is it good that he has a sofa and I can rest separately, or is a shared bed better?
