My name is Chris and I have a crush on my sister's friend. She and my sister are very close friends and they are about to graduate from high school soon.
One night she comes over for a sleep over and she asked my sister if she can take a shower, my sister says yes. Knowing that she is naked in our shower turned me on so much. Once everyone was sleeping I went in my sister's room to turn off her t.v., they went to sleep with it on.
I noticed her friends used panties in a bag and it made me horny so I picked up her panties and went to the bathroom and wrapped them around my penis and masturbated. It felt real good having her used panties on me while I masturbated. I can't wait until the next sleep over.
