Winter time masturbating

Love winter as I lets me wear my long furry winter coat completely nude underneath only wearing my boots of course. Being able to touch myself in the store on at the public park I feel so sexy and turned on watching people walk by while I,m fingering myself. Casually end up going to the rest room when I need a good orgasm. Did get caught once during orgasm guess I started moaning pretty load and a woman in the next stall knocked on the door asking if I was all right. I was so scared and embarrassed.
