Decision made with my son ()

In bed that night all that kept going through my head was seeing my sons face absolutely covered in my fanny cream, i kept tossing and turning i could not sleep ,but the one thing i did know for sure was it turned me on so much i know it should not have but it did and even as i thought about it as i lay in bed i could feel my fanny getting wet ,it was all i could do to stop myself from getting up and going in my sons bedroom to sit on his face , i really could not believe i was thinking about it what kind of Mother am i, i don't know what time i finally fell asleep but when i woke up in the morning i got up to have a shower when i got out i dried and then went to my wardrobe to get dressed, i found myself getting out not my normal clothes i would wear but clothes had not worn for a while what my ex husband would call sexy i put on a black lacy bra that pushed my big tits up and black lacy knickers with this i put on black with white print dress on which was very short and low cut, went out of my bedroom and when i walked by my sons bedroom i called and said "Ryan i want to have a word with you when you get up in the front room " he said " ok Mum i will be down after i shower", i went in to the front room and caught my reflection in the mirror on the wall it stopped me in my tracks my tits were pushed up by the bra and really stuck out and the dress was so short
