A key

I open up the envelope to discover a key with no marking or indication where it went so I check inside the envelope and luckily my husband did leave a note with instructions:

Happy Anniversary my love. I have given you a bit of treasure hunt with this key and I hope it leads to much excitement for you today. I look forward to hearing about your adventures. The first clue for you is this key goes to a lock somewhere in the backyard so make haste.

I giggled as I was excited to where this adventure would lead. I was so excited that I hopped right out of bed and still just wearing my husband’s old shirt and holding the key in one hand and his note in the other I made my way to the backyard. I felt the cool morning air remind me that I was without any panties or bra as my nipples hardened and pressed themselves against my shirt while the cool breeze kissed my naked pussy. I looked around for anything that looked out of the ordinary and noticed something reflective under one of the hedges. I hurried over to it as I felt my tits bounce around freely inside my shirt and I got on my knees on the damp grass. I had to really reach under the hedge and I felt my shirt riding up as more of my ass was being exposed to my neighbors should they be looking out their window.

I got my fingertips on it and I was finally able to pull it in to see it was a small metal box that was fitted with a lock. My excitement was taking over as I sat my bare ass down on the damp grass and I fitted the key into the lock to discover another key and a new note:

Great job finding this clue! I knew to keep it relatively simple since the beginning of an adventure should be relatively easy. Your next clue can be found taking a dip.

I got myself up and brushed off the bit of water that was on my ass and went back to the pool area to see if I could see where the next clue was and low and behold in the bottom of the deep end I could see another metal box hanging out at the bottom of the pool. I contemplated my next move to getting the next clue out of the deep end.
