I had a long drive and was so horny. When I stopped at a rest stop, I sat down on the toilet and went. When I wiped, I gently touched my pussy and realized I needed to cum. I couldn't take it anymore! I whipped my tits out and started playing with my nipples. I was already so wet! I started finger fucking myself and moaning until people started coming in. I quietly continued to touch myself, rubbing my clit, finger fucking my pussy and jiggling and pinching my big tits. You can hear other people using the restroom, talking, washing their hands, etc. All through the commotion I reach a giant orgasm and cum hard right in public!
