Panties. I spend a significant amount of time looking at women’s asses trying to see what style of panties they are wearing. Seeing an outline of a thong is an instant turn on. If I see a woman’s panties when they bend over it becomes instant reason to jerk off. Knowing the style and color they have on is so hot. I also wear panties when I jerk off and/or wrap them around my cock and cum into them.
