It had been a few days since Sarah had caught me fucking Julie in the back of the shop! There was a new atmosphere in the shop very flirty and each time it came back from deliveries I could tell the women had been talking about me! Sarah seem a lot more relaxed not like her she was always the more business type! Julie a bit quieter I guess I was we were both a little shocked having been caught by our boss! A few days passed and I got back from a delivery to find only Sarah in the shop! We were talking in the office I asked for my wage slip! Sarah passed it to me I was just about to leave Sarah began asking me about the other day! At first she seemed serious but soon became more silly giggling about me liking older women and fucking her friend! I was a little embarrassed which I think she picked up on ! She began to explain how she didn't mind but she had been single for a while and with putting a lot of her time in to the shop she hadn't had a lot of sex recently and basically asked if I was up for fun with her as well! I said of course my cock rising in my pants Sarah noticed my bulge and said why don't you take your clothes of! Sat behind her desk she watched as I stripped naked standing in front of her naked my cock pointing at her! She stood from behind the desk eyes glancing at my cock she peeled off her top and took her jeans off she was now just wearing a bra and French knickers! We stood kissing my cock pressing against her stomach as I gripped her pert bum! Not as forward as Julie I took the lead telling Sarah to bend over the desk! She did I peeled off her panties her pussy looking wet already I slipped my fingers in from behind which made her groan! I continued to finger her from behind for a few mins before pressing my cock slowly into her tight pussy! She was very warm wet I took some long slow strokes hearing her take deep breaths! I had only been inside her for maybe 30 seconds when out of the blue when I could feel myself ready to cum! I thought I would slip my cock out t buy some time but as my bell end slipped out of her cunt and the sight of her arse and pussy to my surprise cum began to squirt on to her bum and run down the back of her leg! I couldn't believe I had come this quick! Have you already come Sarah asked sorry was all I could say as still standing behind her my cum shooting on to her bum! This was my first premature ejaculation experience I couldn't believe it had happened with my boss! Sarah just found it funny how I lost control over the sight of her bent over the desk! Tho this wasn't our last fuck! Let me know what you think do you want to here more??
