Mike and I are never going to be like that. I just don’t want you to be shocked. Mike told me they’ve only ever been with each other. Can you imag...ine?! I listened to my best friend since c***dhood ramble as we drove to her in-laws vacation home. I was single again and spending a 2 weeks holiday with her at her husbands f****y vacation home in Hatteras. We arrived and I hugged her hubby, Mike. Then shook hands with her mother-in-law Amy, and her father in law, Les. They did indeed sl**p in. I came from mu duty.This time I saw her by near view. She was having a stunning fair colour with round shaped innocent face and brown eyes. Her chest help a nice pair of well rounded boobs with clearly visible hard nipples. Her buttocks were like to mountains on a flat region. Her clearly visible belly with a well round navel created a lust in my mind. But, She was my sister and I had to hold it back. Just looking at her made me hard and my hot iron rod was jumping inside my trousers. I had my. How is it that their tastes can vary so dramatically, I thought to myself as my tongue was busy irrigating her sweet slit. Doreen still hadn’t moved but rather continually squeezed my pulsing cock with her pelvic muscles. I was trying desperately to ignore how close I was to orgasm, and so far, it was working.Obviously, I couldn’t see anything, and my hearing was somewhat restricted, but I imagined the girls were kissing. I also hoped that they were groping each other’s breasts to give. It was in the high street. It was well fitted out. As well as Mr and Mrs Walden there were two staff member, Patrick and Teena. Both about my age. Both had Marketing Degrees, I found out. Mrs Walden introduced me as the new receptionist and I got the feeling that they were not impressed with me or my outfit, although I did catch Patrick checking me out. Guys are so easily impressed. I settled down at my desk and immediately the phone started to ring. Mr Walden had given me ***********s to read.
