My son is becoming more and more fixated on my panties. He has been taking them and cumming in them. After a long day of work I intended on resting before dinner. I asked him if he needed anything before I did so and he lifted up my skirt to see my panties. Being overly exhausted I just removed my panties and told him to go take care of himself with them. As I laid in bed I couldn't help but think about what he was doing. I start to touch myself and as I'm about to orgasm he comes in the room. I have him fuck me until he cums inside me and we are both satisfied.
