Short but sweet

I've always had a thing for the MILF who manages a newsagents I've been serving for 4 years. One particular morning I was having a good day and arrived before she opened the shop, the day was about to get even better. She opened the door to let me in and locked it behind us, I left her delivery in the usual place and went to the stock room to get the returns. "where's the returns?" I asked, "there aren't any" she replied, giving me a sultry look, there was a naughty sparkle in her brown eyes. She pulled me towards her, kissing my lips softly "we don't have much time, I have to open up in a few minutes". I lift her t-shirt and unhook her bra, revealing her small but perfect breasts, I start to lick her left nipple, she pulls down her jeans then panties, guiding my hand to he pussy as I move to her right breast, I suck on her very erect right nipple while slipping my finger into her pussy, gently massaging her clit. I remove my finger from her now wet pussy as she turns round and bends over the boxes, her firm ass looks very inviting, I probe her ass with my finger, lubing her anus with her juices. "Can I put it in there?" I whisper, "oh yes!". I drop my trousers, then rub the remainder of the juices from my fingers onto my now throbbing cock, and push it gently into her tight ass. She sighs as I begin to push slowly in and out, I increase the pace, but only a little "oh, oh yes!" we are both so turned on by the sheer naughtiness of our act, I push a little harder and faster once more, she reaches out and clings on to the stock room shelving, gasping in orgasmic pleasure as I too reach my climax, filling her ass with my warm spunk. We dress quickly, a quick kiss and she opens up the shop and I'm on my way, it was short but sweet, it had to be, after all we both had work to do...
