Tiffany's Panties

This is an absolutely true story. My wife and I have been married for 18 years, and due to some health issues and body image issues she has, we have only been sexual about 5 times a year for the past 8 or 10 years. Obviously I have relied on masturbation as my main source of relief during all that time. This is a story about some help I got from her best friend. My wife's best friend (let's call her Tiffany) is gorgeous - late 20's, dark hair and big bright eyes, large breasts, full curvy ass, cute smile, and a great personality. She and I hit it off right away, and as time went on, we began flirting everytime she came over. Soon we began secretly messaging each other, which led to dirty talk, and then to exchanging nude pics. A few times when she was visiting, we kissed, touched over clothes, flashed each other, and once she even stroked my bare cock a few times before heading upstairs to see the wife. One summer, "Tiffany" came over to swim with my wife. She headed toward the bathroom to change, as wife was already outside. As I walked past, I remarked, "So, while you are out there swimming, your panties are going to be here unguarded" with a big smile. Tiffany replied, "I had thought about that. Feel free to enjoy them."  After she went out to the pool, I gave it a few minutes and watched to make sure they were occupied. Once I felt it was safe, I headed to the bathroom and locked the door. Tiff's shorts were in a pile on the bathroom floor, and there inside, were a pair of black cotton panties. They were still warm and a little damp. Mmmmm Unfastening my shorts and dropping them to my ankles, I lifted her panties to my face, placed the gusset at my nose, and inhaled. Oh my God! So strong! Her pussy smell was intoxicating, and my free hand stroked my hard cock as I enjoyed her scent. Moving to the rear of the gusset, I found the spot where her perfect little asshole (Yes, she sent me pics of it) had sat, and the aroma was incredible. It didn't smell of shit at all, but a rich, musky, earthy smell that had my dick dripping.  Before long, I felt my balls begin the tell-tale tingling and tightening, and I knew she would be ok with it, so with one last whiff, I brought the black undies to my straining cockhead, and as I stroked fast with a firm grip, I unloaded several ropes of cum into her sexy panties. When I had finished, I folded them carefully keeping a small puddle in the crotch, and laid them carefully inside her shorts. When they had finished swimming, Tiffany headed into the bathroom to dry off and dress, and I anxiously awaited her reaction. When she came out, she and the wife chatted for a bit before they planned to head upstairs to hang out. As my wife led the way, Tiffany hung back just long enough to whisper "You taste delicious!" She shared later through messages that she had greedily licked all of my semen from her panties, and talked about how wet she had gotten thinking about me jacking off for her. She began a new relationship about a month after that, and it was our last encounter, but when she and her now husband stop by, we still share knowing glances, realizing that I know how her pussy smells, and she knows how my cum tastes.
