This was about 20 years ago. My husband and I decided to give him a very special gift on his 19th birthday. During his teenager years I found out he fantasized about me, he used to go to my bedroom and masturbated while smelling my panties and bras. I found out because he made it everyday when he was home alone and started to leave behind some "evidences". After talking with my husband (his step-father) we decided to give him what he wanted when he turned 19, and this is what we did then.
