Panties & Messages from Mom

When I was a teen, masturbating almost daily, I found myself looking for new ways to arouse myself besides looking at the usual porn online. One day, I was putting some clothes in the hamper and noticed my mother's panties lying on top. I picked them up and examined the crotch. There was a crusty stain in the front and a dark smudge towards the back. I held her panties to my nose and breathed in the smell of her excretions. Almost immediately, I felt my cock stir and get hard. After checking to make sure nobody was around, I pulled down my pants and started to stroke my cock while sniffing my mom's panties. It didn't take me long and when I started to cum, I shot my load into the crotch of her panties, rubbing my cock head against the fabric. The orgasm was one of the most intense I had experienced and I felt myself still shaking and excited by what seemed like such a naughty and taboo act. When I was done, rather than hide the evidence, I got this crazy, dirty notion and left her panties on top, with my puddle of cum in the crotch. The next day, I came home from school and when I went to my bedroom, I found a small package on my bed. I opened it and inside was a note tucked into another pair of my mother's -- very clean -- panties. I remember my hand was shaking as I read the note, "Please use these panties next time... Love, Mom." At first, I freaked. My mom wasn't mad, she just wanted me to use a different pair of panties. What I had done the day before was a kind of spur-of-the-moment, one-of-a-kind sexual act. But now it had become even better, more taboo with my mom's implicit approval. I felt myself getting hard again. Within a couple of minutes I had deposited a nice load in the new panties. The only problem was that they were too clean. I couldn't smell my mom. So I sat down and wrote a note back: "Could I please have a pair of your soiled panties. I love how you smell!....Chris." I put the note with the now-cum soaked panties back in the bag and placed the package in a location where I knew my mom would find them. The next day, after school, there was a package on my bed containing my mom's panties and a note that said, "Is this what you mean?" I looked at the panties and at first they looked clean, but then I smelled the crotch and breathed in the powerful aroma of a woman's pussy. I know that smell now, but it was the first time I had really smelled the musky scent of an aroused woman. I became very excited when I realized my mom must have masturbated in her panties, wetting them with her juices before putting them in the little bag with the note. Every few days, I would get a package with different panties, some heavily scented with her musk; on certain "bonus" days there would be a pair of panties with both her musk and a dark streak where the panties must have rubbed against her ass. With each soiled panties would be a mom from my mom: "Hope you enjoy these"...."I was feeling very frisky!"...."Oh my, those last panties were covered with your cream"...and so on. With each pair, I would deposit my load and return them in the bag with a thank you note. Throughout all this, we never said anything openly to each other. It was our little secret that existed in the notes and the panties. One day, I got brazen and after depositing my sperm load in her panties, I took a picture with my digital camera of my half-erect cock, stilll oozing cum on to her panties. I printed it out on our printer and wrote, "A token of my appreciation." on it, and then put it in the bag with the soiled panties. The next day, I found the package on my bed and nervously opened it, half-expecting a note saying I had gone too far. Instead, what I found blew my mind. Inside was another pair of her panties and a self-portrait, from the waist down of my mom wearing her panties, which clearly had a damp spot on them! In her note, my mom wrote, "I believe this is what you want to see. Now be a good boy and destroy this photo, just like I did with yours. Love, Mom." That was the one and only photo she sent among the notes and panties that continued to keep me in a state of bliss that year.
