Had a lot of fun with the girl's panties that week, could probably write another story or two.
One of my most memorable experiences with panties was a couple years back when I was in the eighth grade.
My class had gone on this annual grade 8 class trip for a week in a big city that was pretty good, especially coming from a small town in the middle of nowhere.
For the whole week we did the regular tourist type stuff while we were there, shopping, checking out the sights and attractions.
The class was pretty evenly split with seven guys and eight girls who were all pretty hot, I loved the way their wardrobe changed now that they were in the big city and started wearing more revealing clothes like short shorts and tighter tops that showed some cleavage for the ones who already had some nice boobs.
All the stuff we did while in the city during the day was pretty fun but I had most fun during the nights when we were back in our rooms. We had stayed in an empty college dorm that was done for the year which was pretty cool and everyone did their laundry in the smaller separate building that was connected to the dorm. That was the building I had the most fun in all week, everyone would just load up their laundry and leave it in the dryer all night and pick it up in the morning.
The second night there a lot of the guys did their laundry and few girls did too. I saw the opportunity and tried to keep track of who used each machine so I'd know which girl's panties I was using. I went back later that night around one in the morning while everyone was sleeping, I came up with an alibi saying I couldn't sleep and thought I might as well get my laundry just in case anyone came in while I was there. Luckily no one did and I made my way straight to this one girl's machine, let's call her 'M.'
M wasn't the hottest girl in the class but she was so cute and had that "girl next door" look about her. She was tall and skinny with long black hair, nice big tits (36C, checked her bras) and a nice tight ass. I had a big crush on her and checked her out all the time because she would always wear tight skinny jeans and tees and tanks that showed some cleavage. I dug through her machine and took out the two bras and panties I found and went into the back room with them to have some fun. I just sat there stroking with her panties and rubbing my dick in her bra cups while looking at some pics of her on my phone including one I had managed to get of her bending over showing her legs and ass and another one that showed off her tits.
An idea popped in my head so I went back to her machine and pulled out some more of her clothes including a camisole, pair of short shorts and some socks. I took two of the pillows that were in the room and dressed them up in her clothes, one just in bra and panties and the other with those and her clothes I had grabbed and stuffed the bras with socks. I took turns humping both for a long time imagining I was fucking her and came a ton. My first load was a big one all over the back of her panties and in the crotch. Shot another couple smaller loads over the cami, crotch of the shorts, over one of the bras, and a last one with one of the panties wrapped around my cock but it was a really small load. As I left I put everything back in the machine and let the dryer run so the cum wouldn't be too noticeable and grabbed one pair from this girl we'll call 'G.' I headed back to my room and hid the pair in my bag and called it a night, it was about 3am when I got back to my room.
