Sister In Law's Panty Drawer

I was asked to watch my sister in law's house while she went away. No problem. She is 5'3 and 110 pounds. Perky body. She was going away for a long weekend and I was there alone. She wasn't gone half an hour and I had already emptied her panty drawer on her bed. She wears a size small and all of it was Victoria's Secret. Thongs, panties and boy shorts that I all tried on. It is a huge thrill knowing her pussy and my cock are in the same space. She also had a small toy drawer with a few vibrators and a black dildo. Of course I played with both, sucking on the dildo and then fucking it. I came up with a plan to be fake sleeping when she got home. I would be wearing a pair of her panties with the dildo visible next to me. I wanted her reaction. I also wanted her to fuck me with her toy. I chickened out but hope to do this in the near future.
