It was Saturday night and time to get ready for the party, being a fancy dress theme I was going as Fireman and my wife Brier decided to go as a slutty school girl she really looked hot in a red plaid skirt and white blouse complete with heavy make up and her long black hair tied into pigtails. "There will be a few blokes jacking off thinking about you tonight" I said she smiled,winked and flashed her white g-sting at me "No chance for them to get this" she said as we walked out the door to the waiting taxi.
At the party we separated into groups, men all standing round talking and the woman on the other side, it was a big place with a pool and a sleep out next to it. During conversation I was introduced to Jeff a hulking figure who was dressed as Julius Cesar as we chatted he surveyed the area and said "Bet you I could fuck that little fillie school girl if I wanted". "That's my wife!!" I replied shocked "Tell you what" he replied "If I cant fuck her I'll pay you $500". "And if you do?" I asked "Well I get to fuck her don't I, and you get to watch, see that sleep out down there?" as he pointed "Go look in the back window I'll keep it open so you can hear her moan" "Yeah what ever" I said"Just be ready with the $500" I said.
The night wore on more drinks were consumed I noticed out of the corner of my eye Jeff walking up behind my wife he walked right up behind her and gently placed his hands on her hips and leaned down to say something in her ear, to this day I don't know what it was but a few seconds after he spoke she leaned back towards him as his large arms snaked around her thin waist and she pushed her ass towards his crotch.
No one else seemed to notice this going on he whispered something to her again she looked at him disgusted and walked off inside "excellent" I thought and went to use the toilet.
After returning I couldn't find my wife anywhere I couldn't see Jeff either I went down to the sleep out and crept around the back my heart stopped I could hear it before I looked in the window.
There was Jeff standing there with his toga on the ground and my sweet Brier on her knees in front of him with her back to me sucking his prick. Jeff looked up and smiled and winked at me. "God shes actually doing this" I thought "I hope he's going to use a condom". Jeff grabbed Brier by her arms and lifted her up to her feet and quickly undid her blouse and tore her bra off and started to massage and kiss her breasts one of his hands slid down and started to pull down her g-string, she never resisted, they had now moved side on so I could see more of what was going on, Brier was stroking Jeff's big 10" cock all glistening with her saliva, bits of dribble still ran down her face and both were starting to look rather sweaty.
