I swapped my wife's used tights again !

I had agreed to swap a pair of my wife's used tights with another internet user who would be sending a pair of his wife's used tights .l packed and posted some of my wife's better fine denier tights and eagerly awaited his package .Did not have to wait long before the eagerly awaited package arrived ,a fine light tan pair of great quality tights which I could not resist using to have a great wank with ,all the time making sure not to stain them as l was going to pass them off as new and l had purchased them for her .A few days later at bedtime l casually mentioned that l had bought her some tights and had even cut a hole in the crotch area .(This was not true but l had to account for the fact they had been used and already had the crotch area removed )l handed her the tights and she seemed to approve of them and started sliding them up her legs ,as l have said these were quality fine tights and looked great on her legs and ass.She asked if l wanted to start off with a foot job and of course I readily agreed .My favourite position has always been with her kneeling on the bed with me behind and my cock between her soles as I can also get a perfect view of her ass in nylon. l stood a few minutes of this action but wanted this session to really last for as long as possible so got her to lay down flat on the bed and got my cock onto her nylon ass and started rubbing off on that beautiful nylon covered ass .This was heaven but l intended to hold back for as long as possible and make use of the open crotch area that had kindly been prepared for me .Even though my cock is very thick l had no problem entering her ,she was obviously loving this as much as me and began encouraging me to thrust hard and shoot off all over her ass and legs when l finally cum ,I could not hold back much longer and her begging me to soak her nylon legs and ass was not helping me hold back ,also her telling me to do it now soak my ass did not help and l quickly pulled out and started shooting a huge amount ,not only over her ass but down both legs ...she was covered ,and as she slowly removed the soaking tights she said "l like these tights ,where did you get them from ,I would like a few pairs of these " l obviously could not tell her their origin but just said "eBay "l hope the tights l sent give as much pleasure as l got from these one's!!!!!!
