I used to live in a shared house while I was studying at uni. There were four guys and two girls living there. I wasnt that attracted to one of the girls but the other was really hot. She was way out of my league so one day when no one else was in I went into her room and took a really slutty thong out of her underwear draw. I used the thong to jack off with and once I was done I put it back in the draw I got it from.
