Calling with my hubby while fucking my son

My husband has been away on business for a week, so, i haven't been getting laid. Of course i'm horny. So i call my husband to say hi. I am wearing his flannel shirt and my little panties. While talking to my husband, we both get worked up and decide to have phone sex. Just then i notice my son, standing there watching me. So i gesture him over, onto the bed and i do to my son all the things, i'm talking to husband about doing to him on the phone. My husband and my son both come at the same time. It was like having a threesome with both of them.
