Gooning to my girlfriends underwear

Every morning for the past week after my girlfriend leaves for work, I’ve been gooning with her underwear that she wore the previous night. For the first 5 to 10 minutes I spend smelling them as I slowly stroke my dick. After I wrap her underwear around my dick and jerk off with them for the next few hours i spend blowing loads into them, covering them with a sticky layer of cum for her to find when she gets home.
