My wife's car was in the drive along with two other vehicles I have not seen before.I went round the back of the house and let myself in quietly throu...h the kitchen door. The house was a mess; there were a couple of empty bottles of wine in the kitchen and a trail of clothes leading towards the stairs. Following the trail I worked out there was more than two people involved. I could recognize my wife's clothes, but also came up with what appeared to​​ be two pairs of men's pants!As I went up. She reached down and began pulling the length. Walter told her to stop right there but before he finished the sentence, she had him in her mouth with her warm and wet lips wrapping him and the talented, skilled tongue already sliding on the shaft up and down. In a second, Walter knew, her sister was giving him the best head job and he was loving it. Soon she was pulling his shorts down with her free hand as she did this Walter pulled her sweet ass towards his face. Sasha obviously knew what. You’d better ask him” she said disappearing into her room, something was going on, Del in her way was being very secretive or she had been sworn to secrecy by you know who, a few minutes later he came back I took hold of his arm and dragged him into the bedroom and sat him down on the bed, “now, before I tear your head off, will you tell me what is going on and where are we going tonight that is so important that your tame monkey can’t tell me” I said staring at him, he took my hands, “have I. ....mmmm your looking dammed good girl. Are you ok after yesterday you seemed stressed" Yes I'm ok now, really sorry for bothering you I know your very busy and you have other students taking your precious time. I shouldn't have been a pest." Now don't you worry your pretty little head about that. Your my favourite student of all time and above all else, your my friend"Sylvia giggled...'and lover......'"Yes we did get a bit steamy didn't we. I felt very guilty cheating on my invalid wife..
