as most couples on here we have spoken of inviting a third party into our sex life but thats all as Debra my wife alwyas dismisses this as she is a bit of a prude where this is concerned even though she enjoys sex. Anyway this is a story of how this actually came about when we went to a summer BBQ at a work colleagues of Debras. We arrived and I was introduced to a lot of people who I had never met before and found it quite awkward trying to small talk with people i didnt know. Debra however knew most of them as they were colleagues and was busy chatting to several people at a time and laughing and joking along with them. The day went on into the evening and drinks had been taken in abundance and most people were jolly and having fun. I got talking in depth to a woman by the name of Sarah who worked at Debs office and the subject got around to people at the office. She was telling me all about different people there and who was seeing who and who fancied who that sort of thing. I decided to ask her the question if anyone at the office fancied my wife and she informed me that their supervisor Steve had a soft spot for her and pointed out that Deb was in fact chatting to him at that time. He was a guy of mid 30's and reasonably fit but nothing special and I thought nothing else of it and continued to chat to Sarah. As time had gone by I had sat in the large garden and just chatted to anyone who passed really and lost track of the day. I looked around and couldn't see Debra anywhere so decided to find her and use the loo at the same time. I walked through the garden to the house but she was nowhere to be seen so I went in to use the loo and walked up the stairs. As I got to the top of the stairs I noticed a bedroom door open slightly and could see through to a reflection in a mirror and to my surprise I saw the guy Steve naked and obviously having some fun. I pushed the door open a little more to have a pervy look and then saw what I thought I would never see. There was in fact not just Steve in the room but another guy as well and between them both was in fact my wife Debra being well and truly spit roasted. Debra was hungrily feeding on the other guys cock and Steve was pumping hard into her from the rear. She was being treated like a slut by the pair of them and steve was reaching forward and pinching and playing with her hard nipples. Now debra is a larger lady size 18 with 40DD breasts and as Steve and this guy fucked her you could see her whole body moving and breasts swinging. I was frozen on the spot as i looked at this reflection when I heard Steve say "I am going to cum" and at that he shot a full load of cum into my wifes belly. He withdrew from her and said to the other guy "c'mon Rich your turn now you have always dreamt of this" and at that Rich moved from the fron of Debra and entered her from the rear and pumped hard into her before he too released a load of hot cum into her. They both just stood there and Debra looked at them both and said "thanks guys I have wanted that for such a long time" and looked down to see cum oozing out of her swollen pussy. I realised then that they hadn't used any protection on her and this i must say got me quite excited. At that I moved off to the bathroom to collect my thoughts and waited until I heard them go downstairs then followed a short time after. I resumed my position in the garden chatting again to Sarah who I think realised what Debra had been up to but never mentioned anything. Debra came over and asked if I had enjoyed myself and were we ready to leave. In the car on the way home I mentioned what I had actually saw and Debra didnt know what to say and was close to tears when I assured her I was ok with this and found it erotic watching her. Debra pulled the car over and admitted to me that she had been seeing the guys for a while and blamed it on the fact that I was always going on about a 3 sum and she had decided to venture into that realm but without me. At that she undid my flies and went down on my cock and began to suck me, well I was ready to explode after what I had seen and duly obliged as I shot a hot load of cum up into Debras face and mouth before she cleaned me up and continued our journey home.
