My cock went semi almost immediately...good boy....I could see she had her hand in her knickers with her skirt hitched up and was playing with herself...she never saw me looking at her as i was positioned for full exposure but her not being able to see my eyes.I was getting harder all the time and thought i'll have to cover up soon, i was now covered by the towel and a semi sticking out but that was ok, i headed back to the dining room with my wet clothes which she took from me. She lit the fire. Oh, and her manhattan as well. She raised her glass and made a kind of informal toast. To the future,” she said. I nodded my stem-glass in her direction and sipped as she did hers; I kind of gave her that one.We decided to eat before we got into anything heavy. And we did, eat that is.Done eating we ordered another round of drinks. They came and we settled in for the big show.We kinda stared at each other for a long moment. She broke the ice.“So, Lance mentioned that weekends would be best for. I got indulged in the kiss too and started chewing her lips. Just then I burst out into laughter and broke the kiss.She frowned on me and asked in angry tone “What now?!?!?!??!”I just shook my head sideways with a laugh and said “Strawberry lip gloss”.She sheepishly smiled and pushed me. As I was about to fall on the bed nearby, I held her wrist and dragged her along. I fell on bed and she on top on me. She started hitting me on my chest childishly, immediately I held her face and started. After her sobs ended the sisters sat and sipped their scotch in silence for twenty minutes or so. Martha broke the silence by asking, ‘What should I do?’ Mo immediately suggested that she find his hotel room, walk in naked and fuck him into the last century. Wendy and Martha giggled at the suggestion and that turned their mood to the better for the rest of the day. They did come up with even more outrageous plans that had each other in stitches but they settled on simply asking him to join.
