Playing at My Friends Apartment

I hosted 3 people and myself during one of the recent hurricanes. The last to get power back and go home was my friend Erin. I have always had a crush on her, but the feeling isn't mutual. She still teases me, and knows I really want to touch, taste, smell, and enjoy her. She is 11 years younger than me, and isn't into older men. She trusts me enough to give me keys to her apartment so I can check on her pets, or drop something off. On the third day after the hurricane had passed, she was back at work, and texted me to go check out her apartment to see if the power was on and see if anything happened there after the storm. I got to her place on the third floor, and yes...the power was back on. It hadn't been on long, because the apartment was still warmer than normal. I looked around the apartment and on her lanai to see if there was any damage or water spots on the ceiling. I went into her room last, and right there on the floor was a pair of her very silky and worn panties. They were on the floor with the edges of the leg opening curled up after being taken off quickly. It had been 5 days since I had relieved myself of sexual tension, and I couldn't resist. I picked the hot pink panties up and unfurled them to view them in their entirety. As I opened them up, I got that wonderful smell that a woman emits from her pussy. I imagined it in my mind that her nicely shaved and sweet smelling pussy had been played with before dropping them to the floor. My cock was at full attention, and there was not enough room in my shorts to hold it in. I had never undressed in her apartment before, but I got that way in her bedroom.  I took another smell of that musk that had triggered me in the first place, then I took the panties in my left hand and started rubbing the crotch over my engorged cock. It is only 6 inches, but I've been told it is nicely thick with a beautiful circumcized head. I was in exstacy!!! I started imaging my beautiful blonde friend slowly undressing for me. Teasing me going slow. My hand was going slow to help with my excitement. She was down to her bra and panties smiling at me and my incredibly hard cock. The panties felt so nice on my cock!!! Since it had been 5 days, I'm suprised I was able to control the speed to a slow motion...just teasing myself. She slowly undid her bra, and her beautiful 34C's came out with these beautiful medium sized nipples that were as hard as my penis. At that point the hand and panties started to go faster, and a little precum started to form at the tip of my penis. It got smeared onto the panties which just excited me more!! In my mind she dropped her panties and went and layed on the bed with her legs open for me to come enjoy. The pressure was really starting to build up in me at that point. I tried to slow it down, but couldn't. It was too much, and I exploded back onto my chest, a little on her bed, and some on her panties. It was an incredible experience! I had never masturbated with a womens panties, and now I only want to. I wiped myself up as best I could. I wiped the panties to get most of my cum off of them. It excited me more knowing I left a sign for her that I came in her room. It kept me aroused, and I had to play again later. I put her panties back as best as I remembered first seeing them. It has been a couple of weeks and she hasn't said anything. Maybe she will read this and know what pleasure she gave me!
