Watering Neighbors Plants

Im home from college for a month. My Mom is watching our neighbors house for a couple of weeks while they are on vacation. My mom and dad had to leave for the weekend and asked me if I could take over watering plants and keeping an eye on the neighbor's home for a couple of days until their return. I know the neighbors fairly well since they have lived here next door my entire life. They are a nice couple a few years younger than my parents and have adult kids living in different states now. We had a crazy drenching rainstorm the other night. I went over the next morning to check on things and discovered that a couple of windows in their main bedroom had really leaked and soaked the carpet underneath them.
I found some towels in their primary bathroom and began to sop up the water. While searching for towels I came across a fancy Victoria's secret box under the bathroom sink. I have always thought that Mrs. is pretty and I was curious what her lingerie might look like, so I opened the box. I found a few sheer things like a bra and thong panties. Under them however, I found a couple of vibrators, one realistic looking and another silver metal bullet thing. At the very bottom of the box, I found a small floppy plastic purse size album of pictures.
All of the pictures are of the neighbors and seem to span years, since a few are the quick developing kind from an old camera, and the neighbor woman is much younger. They then seem to switch to digital camera and are more recent as I looked. I was rock hard seeing the Mrs. like that after knowing her my entire life. I had to stroke myself as I continued to look. The Mrs. had a really dark hairy bush but had really wet swollen lips in the pics of his hard cock pushing into it. She also had larger than I thought boobs with large areolas which were really sexy. What I didn't expect since I'm not or have never been attracted to men was that the pictures that had me stroking hardest were of Mr.'s hard cock buried deep in her or her rubbing his big head on her clit. I had the biggest ejaculation I can remember looking at a pic of him cummings on her wet black bush. I had to return just a few hours later to look at those pictures again.
