I thought it would be just helping my brother. Boy, was I wrong.

My brother, Brian, and his wife, Leena, rang to say they were going on holidays and could me and Cathy look after their Doberman for two weeks. I didn’t bother to ask my wife, Cathy, as I knew she wouldn’t be too keen on having a dog around. I thought it would be funny watching her fend off Horas (that really is his name) as my brother had let slip one day that Horas was “intact” and I suspected that he pleased Leena. I was shocked at first but held my tongue. Of course my impression of Leena changed.

I told Brian I would be happy to. After all brothers always help each other. They arrived on Friday night with the dog and all the bits and pieces for him plus a shopping list of food. Wow, he ate nearly as much as me. They said it was a load off their minds that they could leave him with us. I expected Cathy to arc up once they left but she was calm and went about organising things for the dog. I was a bit upset as I had hoped she would complain. I just love teasing her and making her mad. It usual ends in wild sex. This time, nothing.

Once Horas was settled we watched a bit of TV and then went to bed. Cathy seemed horny and suggested we take a shower together. After which we had a great sex session. I wasn’t complaining just confused. Next morning we had breakfast and feed Horas. He seemed to have settled in well and Cathy was actually playing with him. I had to go into the office to check some work that was causing problems. Cathy said she was ok with the dog and I should take my time and get the work fixed. I told her I would be gone most of the day.

I got to the office and got stuck into the work and just after lunch I got it done. Feeling very pleased with myself I headed home. I walked into the house and at first all was quiet but as I walked in to the lounge room I could hear moaning and then a squeal.
