I have been married to my wife Wendy for 10 years now she is 58 5ft 5 quite curvy figure iam her second husband her first one Philip was quite a dominant type and had several affairs before they divorced

I have always known that she had a soft spot for him but it never got in the way of our relationship

She did used to talk about their sex life she has a real fetish for a very sound spanking especially by the hand it does figure in our bedroom activities but I can never bring myself to slap her bottom as hard as she craves. One night she asked me would I mind if she met her ex husband and he would spank her in front of me to demonstrate what she would like from me

I thought it over and came round to the idea but when I said yes arrange it she left me genuinely astounded as she said he is a very dominant and arrogant man that when they were married he always wanted to shag her after the spanking . However she contacted him and as she predicted in return for spanking her he asked her for sex and also further asked that I would watch

For a couple of weeks I held out but she persuaded me as she said over all the years he has had her far more than me , she was married to me and only wanted to be with me but the spanking she really missed

So we arranged for Phil to come over on a Saturday afternoon we had a couple of drinks and he remarked to me how much he was looking forward to the afternoon and how impressed he was by me being so considerate and understanding.

So it started my Wendy was dressed in a burgundy blouse and black skirt .Phil called her over where he was sat on the three seater sofa she stood in front of him and said you wanted me sir , he said assume your usual position with that Wendy positioned herself over his knee , I watched in fascination and horror as he lifted her skirt right up above her waste and quickly pulled her tights and then her knickers down to her knees exposing her curvy bare bottom then immediately slapping her bottom very hard several times pausing briefly to tell me this is what she wants and needs and I should be man enough to provide it

He then told her to stand and show me her bottom that had his handprints emblazoned across her buttocks

He then told her to strip naked and we both sat and watched as she did , Phil then undid his trousers and pulled them down along with his underpants exposing a thick erect seven inch penis noticeably bigger than mine and he grinned to me and told me that she always liked a good shagging with his cock

Wendy went on her knees and started to suck him after a while he told her to go to the bedroom she started to leave but paused while Phil took all his clothes off he said to me well I’ve showed you how to spank her now I will show you how to fuck her

With that we all went to the bedroom and Phil said to me I think you are a bit overdressed get naked so as they both watched I stripped naked , at this point Wendy climbed on the bed opened her legs and received his bare penis I watched mesmerised as he thrust vigorously with great purpose and how loud she moaned and squirmed underneath it finally he grunted and dispensed his semen into her vagina as he withdrew she leaned up to him and said thank you Phil that’s just like old times and exactly what I needed. He said to me well she’s your life now why don’t you fuck her as well I will see myself out iam not sure you fully learned how to spank her so I will demonstrate again next week

He was as good as his word and for the last few months at least once a week I was reluctant at first but realised how happy she was so parked my misgivings and now actually look forward to it where now I lick his cock clean after he has had her
