your arousal from jerking with your girlfriend's worn panties is growing stronger by the day. It's become a daily release for you. Something about the soft, silky fabric caressing your hard cock. If you're going to be honest- the fact that it's a bit sneaky, dirty, and naughty is an extra turn on. I won't tell- as long as you call me up daily for your dirty panty JOI! Sniff it. Rub it, and blow a big hot load on it.
