cant help myself

I'm 33/M/MI. I tend to house sit my neighbors apartment. She is in her late 50s. We are strictly friends and get along great. Shes always out of town so she gave me her extra key. I gave her mine as well. A few days ago she asked me to check on her dog and feed him while she went camping with her kids. Her kids are actually friends of mine as well. But that's another story. The first night I let myself in. Walked the dog, feed him etc. When leaving I kept hearing a humming sound. I dismissed it and left. The next morning I feed the dog. I hear the humming still. I notice it's coming from the master bedroom. I open the door hear load buzzing. I followed the sound to a box under the bed. It was a baby blue vibrater. Along with a number of other sex toys. I kicked it back under the bed and acted like I seen nothing. I walked the dog and left. She called me later to see how everything was going. I forgot about the stuff I found and we chatted for awhile. Later I went over and let the dog out. I looked over to see the bedroom door was slightly open. I walk fast and go to shut it. I see that I didn't have the box put back properly. I went in and grabbed the box, the toy still humming. I instantly lost my mind. I pulled out her toys and dropped my pants. I licked all of them clean. Stroking myself, with no care in the world. I layed on her bed and jerked myself until climax. I blew everything into her toys I felt ashamed and tossed everything back in and under the bed. I ran out of there in a hurry. I went to bed thinking of everything. I didnt sleep to well. She called me in the morning. I was super nervous but it was a usual conversation so I just went with it. She was coming home tomorrow. I thought I have to clean her things. So I went over and grabbed out her toy box. Everthing was soaked in my cum. It was ridiculous I had that much to put on her things. I washed everything off. Cleaned her sheets and put everything back. I took care of the dog and let myself out. Later I was in bed and i had a video chat coming from my neighbor. I answer it and we have small talk. She keeps mentioning me looking tired and laughing. I'm laughing like yeah it's the middle of the night. Out of nowhere she said she has home security in her apartment. Video cameras everywhere. My heart sunk. My mind was racing. She said she'd been watching me for days and she appreciated me washing out her prize box. And I'm lucky shes so cool or I'd be in jail. Told me to never ever touch her things. I'm currently freaking out as she wants me to have dinner with her later today to talk about what I did....
