I was helping my 18 year old stepson clean his room out last weekend. I opened a box and found a collection of lace underwear...all designed with a pouch to take a penis and ball sac. Some of the panties were crusted in dried cum.
I immediately got an erection and had to leave before he saw I had found the box and that I had boned...I took one of the lace thongs and went and masturbated while sucking on the crusted pouch. I know he is into lace, as I am...where to from here???
