A few weeks ago I was stopping over night at my sisters. After a nice meal I said that I was going to go to have a shower. I went into the bathroom, pushed the door closed, undressed and got into the shower. After a few minutes under the water I got out and reached for a towel. As I took hold of the towel I noticed the bathroom door slightly open.. then a creak on the floor boards out there.. I was being watched. I carried on drying off then when half dry I just asked if they wanted to come in.. No reply.. I carried on drying myself then just pulled the door open to see my nephew (19) there. I looked at him with the towel around my stomach and asked if he was enjoying watching.. He kinda froze to the spot n muttered mmm. I let go of the towel and just stood there fully naked for him to look at me.. Watching his eyes moving between my face, boobs and pussy. I was starting to get that nice tingly sensation on my nipples n clitty as I stood there allowing him to look at me..
