18m using my aunts dildo while wearing her panties

My aunt and her family were away for the weekend and she asked if I could feed her dog while they were away and of course i said yes. The first day I went and I just snooped around took a few pics of her panties and left the second day I was really horny went on a deep search found a dildo and some lube and vibrators, I never tried anything anally before but I seemed my opportunity so I put on my aunts tights and lingerie and tried her dildo it was so painful but suddenly so good I then gave it a good clean and then cummed all over it. Now i constantly think of her using her dildo with my dried cum all over it. This story is fully true not like the others on this sub. Thanks for reading.
