More sex with my neighbour

Found this harder to write than I thought, hope you enjoy my scribblings.

You may already have read about my friend Annie, my neighbour, we like spending 'time' together! One Saturday Annie's geek of a husband was out with friends so we arranged for her to come around. Annie has a plump little ass which would turn most men's heads and recently she's started to trim her pubic hair, not too much, in case Dec (her husband) noticed and inquired as to why she was doing that now.
It was a wet afternoon so we were forced to stay inside rather than spend time together in the garden, we don't always jump into bed sometime we just like talking and spending time together.....with a bit of kissing and cuddling thrown in!
Today she had on a white blouse and a blue skirt which followed the lines of her arse pefectly. Difficult to recall what exactly was said but we found ourselves teasing each other and I said something like 'if you keep on I'll put you over my knee' to which she retorted 'you wouldn't dare'. Grabbing her by the arm, I pulled Annie to me and gave her a couple of light swats. 'Mmm' she mewed, 'you like that' I asked her? 'Oh yes, always wanted to try being spanked and that's unlikely to happen at home'!
'Right' I said and taking her by the arm, leading her upstairs to my den, she stood there looking very unsure about what was about to happen. To explain a little, in my den I have an artists desk where the top can be tilted upwards to different angles which I now altered to a very acute angle. 'Take your blouse off' I commanded 'and from now you'll do what I say'. Still looking a little unsure she did as I asked, moving her round to stand in front of the desk I made her grip the top edge and rest her boobs (still wearing her bra) against the top.
For the first two spanks on her arse, these were through her skirt, but obviously they had little effect, so then I requested she unzip the skirt and watched as it slid down her bare legs and stepped out of it, gone were the frumpy pants that she wore on our first encounter, now she wore something far more attractive. 'Hold the desk again' I told her which she did without question as I raised my hand and brought it down, three times in quick succession, 'Oh ouch' she cried moving a hand down to cover her left cheek, wack wack wack three times on her right cheek, that brought her other hand down, both rubbing her pain away. 'Hold the desk again' I told her which she did, I hooked my hand in the waist band of her panties pulling them down and took my own t-shirt off too, she stood there, legs apart, I could see how wet she was as I slipped my hand between her legs to cop a feel, my cock straining in jeans so hard.
'Want to try something else, do you trust me' I asked her, she nodded, 'look away' I told her which she did, laying her head on the desk. I removed my belt and folded it in my hands, thwack I brought it down firmly but not so as to mark her too badly, she could hardly go home showing a stripe on her quivering ass, making her gasp and once again I brought it down, her legs began to shake as her emotions took over and she came holding tight to the desk for support. I couldn't wait any longer, I was so turned on, I just had to unzip myself and fuck her over the desk, from behind, looking out of the window as her husband's car came down the road as I shot my load deep inside his wife, such satisfaction!
