Michelle was embarrassed I told her maybe Dave can help you out. What Michelle said. Yes my Dave, we have an open relationship, we can fuck whoever we...want we just have to let each other know about it. When we lived in New orleans we just knew too many people and had to be extra secret. But here In Atlanta we can fuck whoever we want, nobody knows us here. Really said Michelle. I can't fuck your husband, we're friends, my wife said that's what friends are for.So Michelle was a little hesitant. I tried to put both the nipples into my mouth simultaneously and as her boobs are big I could able to do so. She started moaning slowly and held my head very firmly. With other hand I entered into front side of her innerwear and touching her pussy. It was very smooth and cleanly shaved, so I could able to reach the crack very easily.Then was trying to go down to lick her pussy, but as the bus front seat guy were leaning on his seat there was very little space. So, I didn’t went down. She lifted. She replied, "he's a good little cocksucker" I looked over at Cheryl and said "do you think its ready to go in your sister's pussy?"She looked at me and smiled. she then started to get undressed. She was wearing a ladies track suit which quickly came off so she was just in her bra and panties. I looked over at her ample figure and said, "that's not fair, you sister is completely naked"She got down next to her husband and they started kissing. She then started to take off her bra to reveal her. I fingered her feeling her inner wetness & removed my finger to taste her juices which were so sweet i could have persuaded myself i was in heaven. Andrea was getting to like the feeling herself that she moaned one more load one & began to move up so we were kissing & touching. She whispered, "may i try to do the same to you & show me more if i am doing it wrong. At this stage i was excited & she would know very soon at just how excited i am, then we swapped places as she went down on me, first.
