Panty Sex With Girlfriend

I told my girlfriend I wanted to try on her panties and she was totally fine with it! I sort of passed it off as a joke at first in case she wasn't into it, but in the end she actually brought me like five or six panties to choose from. It was so amazing both rolling around on the bed kissing and touching each other in panties, I nearly exploded. We left the panties on during sex and both just slipped them to the side and had sex while wearing panties, when it was time for me to cum I pulled out and shot it all over her panties, it was hot seeing my cum all over her black panties.
