It started as out as normal work day except that my wife was away visiting in-laws. I got up, showered, and walked naked to my dresser to get clothes to wear. I got out a pair of jeans but found my underwear drawer was empty. Apparently, I was further behind on laundry than I had thought. I started looking through my other drawers but only found a swimsuit which would be to hot to wear as underwear. I glanced at my wife's dresser.
"Well," I thought, "I guess panties might work." Naked, I walked over to my wife's dresser and started looking through the drawers. I couldn't find any plain cotton panties, most likely because she had taken them all with her on her trip. I did find a small drawer full of lace panties, string bikini panties, and thongs. Now, I like lingerie a lot when it is on a women, but the idea of wearing panties on my body had never appealed to me. The sight of all this sexy lingerie did, however, bring back erotic visions of my trim wife wearing one article or another before we made love.
"Calm down," I thought, "they won't look so sexy on you." I took out a white string bikini that was made from a soft spandex-like material. I bent down and stepped into the bikini and slid it up. I adjusted the back so it felt snug against my rear. The front, however, felt far too small and narrow. It barely covered my flaccid penis. I felt a stir in my groin as I thought about why this bikini felt to small and narrow in the front. This underwear was never intended to cover my male package, it was intended to cover a girl's pussy which was, well, lower.
Without thinking, I started to rub the spandex-like material at the point where it had covered my wife's pussy and felt my balls underneath. This caused my penis became larger and my glans emerged from the top of the fabric. I stopped and stretched the front to cover my now fully erect penis which caused the back to bunch up pleasantly. I started rubbing up and down the bikini front. Slowly at first but with more urgency as the pleasure in my groin grew. With my other hand I caressed my stomach, chest, and nipples. The pleasure grew and grew until I felt my penis convulse with orgasm. I breathed deeply as I felt my penis pulse out wad after wad of cum into the panties I was wearing.
I shuddered as my orgasm subsided. "I'm going to be late for work," I thought as I quickly slid off the cum-filled panties and ran to wash up my still-erect member. I went back to my wife's panty drawer and grabbed a pair of lace red bikini panties to wear. I slid them on and discovered that the tip of my cock was again poking out. "Dang," I thought, "it better get smaller fast." I took my hand and canted my shaft off to one side which allowed it to be covered by the soft lacy material. I quickly slid on my jeans, finished dressing and dashed off to work.
Work was distracting due to my odd-feeling underwear. Most troubling was getting an erection.
