Stepmom shares stepsons bed after fight with husband

My husband and I got in an argument and can you believe, he locked me out of the bedroom?! Well, I wanted to lay down somewhere and the only other bedroom in the house belonged to my stepson. He is a horny guy and I thought it'd be fun to be in his room for the night and maybe I could do something to get back at my husband. When I walked in, he was masturbating. I ended up masturbating with him and then I convinced him he would like it if I sucked his dick and had sex with him. And he did.
