I KNOW WHAT HE CAN SEE
After I get home from work I like to remove all of my underwear and only wear a full slip around the house. I know my son can clearly see my nipples through the lacy material of my slip. He keeps looking at them all evening.
Sometimes he stares so hard I can't help but have my nipple stand up hard. I have no desire to do anything with him but I do seem to like showing off to him.
