Self Shot Public Wank

Whilst out and about shopping I start to feel incredibly horny so there's only one thing to do.. find somewhere to have a quick wank! Going into a local DIY store I search for the public toilets, my sexual desire mounting. I finally find the toilets and within seconds I'm pulling my skirt up and pushing my hand down my already damp panties, fingering my pussy, wanking it hard and fast until I can contain my orgasm no longer and I cum. I organize my clothing before walking back out of the store with a smile on my face.
