I just try to find an out of the way parking spot at a restaurant or shopping center in the area. There's also a near by park that isn't very busy during the week. I'm not exactly looking to get caught but I do like being watched if someone does see me.
I pull down my scrubs so they're around my ankles. This allows me to spread my legs so my knees are on the outside of the steering wheel and insert the vibe. Rabbits make me cum really quick so I'm not exposed like that very long.
Hubby walks in on me while masturbating at home all the time. I don't get embarrassed and stop. Most of the time he just shakes his head, makes an off hand comment and goes about his business. Sometimes he will pull out his phone and take pics or vids. If he's in the mood he might swat the vibe out of my hand and make love to me.
