My Step-SON Helps Me With My Loneliness

My Husband left me a few months back and is already about to marry his mistress. My step-son has been my saving grace, always keeping me company, and caring for me. One night he comes in to tell me he is going to bed when he finds me extremely sad and crying. After asking what's wrong he offers to lay in bed with me so that I am not lonely. HE IS SO SWEET. Unfortunately, I guess I was wearing something more revealing than I thought, and he gets hard, and well... Eventually my hand ends up some where it shouldn't. The following morning, I wake up to me actually PLAYING WITH HIS DICK. I haven't had some one in bed next to me for so long, and I am so used to my husband being there, that it was just kind of instinctual. Awkwardly I tell him he is late for school and get him to leave. I was super horny after that though, and decided I was going to live in the moment and get myself off Little did I know, he was watching from the hall. The following night he gets home from school and I want to talk things out, to make sure things aren't weird, since he is so special to me. As the conversation goes from awkward to honest, I eventually tease him and let him jerk off to me. Over the next few weeks things continue down that path until one week where he has to leave me for my ex-husband's house for the holidays. I want to make sure he knows how happy I've been and how special he is to me, so I let him know that when he gets home I have a BIG SURPRISE.
