Used her panties to jerk off
Me and some of my coworkers went to a conference, stayed a few days in a hotel. My room's water wasn't working so I asked one of my coworkers if I could use her shower. She let me in and went out to get some groceries. Her panties were hanging on the shower curtain bar, drying... I couldn't help myself and used them to masturbate, rubbing my dick in them and ejaculating into the drain. I put them back, no harm done... iin?
