Jane was right, and to be honest, at this moment, I hated her for it. Of course Ian was my friend, and of course I owed it to him to expose his wife’s adulterous activities, but somehow I felt guilt at the prospect. I tried to convince Jane that it really wasn’t any of our business, and we should just forget what I had found. I even pointed out that the evidence was only circumstantial. After all, they may have been taken before they had married, and just because Sarah surfed swingers’ web sites, it didn’t mean she still lived the lifestyle. Jane was on the money though, and dragged me back to the pc to go through the photos again. She stopped on one graphic shot of Sarah’s head nestled between the silkily smooth thighs of another woman. It was a clear and well taken shot, with Sarah holding open the glistening labia of the other woman with her right hand, and inserting two figures of her left hand knuckle deep into her lover’s depths, whilst Sarah’s tongue searched eagerly for the girl’s hardened nub. Clearly visible on her left hand was her wedding ring. I suppose if I’m honest, I knew all along, but I needed to convince myself, through Jane, that this wasn’t our problem. My Jane, ever my conscience, was adamant that we needed to speak to Ian. She was disgusted with Sarah’s betrayal, and quite rightly pointed out that we would never be able to spend time in their company without feeling awkward. She was right. Wasn’t she? That night we had sex again, and it was obvious that our bodies had betrayed us just as Sarah had betrayed Ian. Jane was very aroused when we made love, and very forward in what she wanted. Normally our weekday sessions are relaxed gentle affairs, with me usually initiating sex and adopting the dominant role. I usually make love to my wife. That night she fucked me. I saw a lust in her eyes I hadn’t seen in a long time as she rode me, her wet pulsing depths convulsing around my shaft. Her breasts bounced rhythmically to the rise and fall of her thighs as she rode me. I reached up to her breasts, taking one in each hand, and squeezed her swollen nipples gently between forefinger and thumb. Jane let slip a guttural moan, and silently mouthed the words “HARDER” to me. As I pinched down on the engorged nipples of my lover and wife, she threw her head back and groaned in pleasure and pain. When our eyes met again, she was lost. Lost to the moment, lost to the feeling. Her hips bounced harder and faster onto my shaft, and I could feel her inner muscles pulsing and gripping me. She reached down and pinched my nipples, something she had never done before. The pain was like a trigger, and instantly I felt the moment of my climax rush over me. Jane screamed out, oblivious to everything. Normally she is quite quiet when she comes, always conscious of the paper thin walls in these modern houses, and the proximity of our neighbour’s bedroom, but that night she screamed. I felt her pussy squeeze my cock as it throbbed and erupted a series of powerful jets into her. Jane kissed me and told me she loved me. I smiled and kissed her back, re-enforcing my declaration of love. Jane rolled off me and cuddled up, waiting for sleep to engulf us. Jane had never gone to sleep before with her belly full of my spunk. We didn’t speak of the Ian / Sarah situation that night, but I knew she was thinking about it. And I knew that Sarah’s sexual activities had changed us too. To be honest, I was grateful, and that alone caused me more confusion. Not only were we enjoying Ian’s misfortune, but we were getting off on it. The next morning I told Jane she was right. I needed to resolve this situation, but I had an idea of what we could do, that wouldn’t involve us telling Ian ourselves. We would confront Sarah, and put the ball in her court. However, I convinced Jane we needed more evidence, something we could use without having to admit we stole her photos from her computer. Jane went to work that morning in a bad mood, upset that I wouldn’t just tell Ian what was going on, and I suspect, pissed off that I haven’t thought out all the implications of my new plan yet. I wasn’t sure how I was going to get the evidence I needed, but I was sure of one thing. The key to it all was Sarah’s login name and preferably her password on the swinging site. If I had that I could monitor who she was talking to, who she was planning to meet, when and where. And then I could gather my evidence. I needed to get back into her computer without raising and suspicion. I rang Ian………
