A few friends of mine went to our friends house for a party. He lives with his sister but she was out of town. She is a friend of mine too. She is a year younger than I am, 5'6' tall, probably a size 8, brown highlighted hair and very pretty. She is also naive. She has never had a boyfriend. She is very old fashioned and a very sweet girl.
My friend told me to stay in her room while the other guys stayed in the other rooms and on the couch. When it came time to crash for the night I went into her room and started snooping. Her room smelled so good it just turned me on. I looked in her night stand and under her mattress for a vibrator but found nothing. Next I checked her underwear drawer. I didn't find a vibe but I checked her bra size. 34C very nice! I started rifling through her panties. They were mostly plain except for one pair balled up in the back. They were lace with a bow in the front. What piqued my curiosity was that the crotch was chaffed right out of them. The only thing holding them together was the white cotton gusset (which was slightly crusty and stained, there also was a brown pubic hair in them).
I thought about this for a minute assuming these must be her panties that she wears to feel sexy and ends up grinding on something to make herself cum. I could be wrong but that's all I needed. I sniffed them and licked them tasting her virgin pussy and then I wrapped my cock in them and stroked until I shot my load into the gusset, mixing our cum together. I let them dry overnight and put them back the way I had found them. I love thinking about her grinding my cum into her pussy.
