Brenda walked upstairs, wondering where Emma and Jim had disappeared to. The three had been sitting around after dinner, drinking wine and telling stories and laughing, one of those rare occasions when everyone was able to forget about work for an evening and just relax. They had all taken off in different directions for a moment… bathroom, more wine and new music, but Emma and Jim hadn't made it back. Brenda knew they were probably in a clinch someplace and figured she'd search them out and give them a hard time about abandoning a dinner guest.
Sure enough…. she walked down the hall and looked into their bedroom - the door was wide open and the two of them were in a passionate embrace, mouths open and hungrily kissing, bodies pressed impossibly close. She started to say something, to get their attention, but suddenly stopped, surprised by her attraction to seeing the two of them together. She watched as Jim's wandering hands moved over Emma's body, and came up to her breasts, touching so gently as the two kissed. His fingers opened the buttons of her shirt, found the front clasp that undid her bra, pulled the cloth away from her and cupped her breasts in his hands. Brenda was familiar with her sister's body from changing rooms at the beach or the mall, but suddenly it was so much more sexy, seeing Jim's hands on those large, beautiful breasts, seeing him kiss down Emma's neck and collar bone, slowly licking and then covering a nipple with his mouth, drawing it in as he sensuously sucked. Brenda looked at her sister… Emma's eyes were closed, her head back, her fingers tangling through Jim's dark hair, one leg sliding up his body to wrap around him and pull him close. Brenda had known that Emma and her lover were incredibly hot for each other, but it was suddenly clear that this connection the two shared was more than two people who wanted to fuck mindlessly…. this was the intensely sensual, erotic connection of two people totally in sync.
Brenda's face flushed and she became aware that her own nipples were achingly hard and her pussy had started to throb from the erotic scene she was witnessing. She turned to slip away quietly, but her movement must have caught the lovers' attention and they broke their embrace. Everyone's face was red as they laughed, and Brenda teasingly said, "God, you two. Don't you get enough of each other without having to get it on when you have guests over?" Emma and Jim looked at each other for a moment and answered at the same time, "No." The three laughed again, Jim turning Emma to face Brenda, arms wrapped around her from behind, resting his head on the top of hers.
The three looked at each other, smiling, for a long, long contented moment, and Brenda moved, riding the impulse that came out of the moment. She walked over to the lovers and reached out her hand to touch one of Emma's still-exposed breasts, running her middle finger slowly around and around the large areola, watching the nipple gather and harden. She looked at her sister's flushed face and said, "So pretty." She sucked first on one nipple, then the other as she stroked and touched and massaged her sister's breasts. She felt hands in her hair, and realized they were Emma's and Jim's. She cupped Emma's breasts in her hands, pressing the palms against the hard nipples and kissed Emma deeply, the two women's tongues sensuously dancing.
Jim ran his hands over Emma's arms as he kissed and nibbled her neck. When the women broke their kiss, he whispered in her ear, "Would you like me to leave you two alone?" Emma turned her head, hand bringing his mouth to hers and kissed him lovingly, "I want you to stay." She looked at her sister, "Don't you?" Brenda's eyes danced as she smiled naughtily, "Oh yes."
They took their time undressing each other, taking in the sight and feel of each others' bodies. Emma reveled in the feeling of Jim's large hands and Brenda's smaller and softer hands traveling over her flesh as they finished removing her clothes. Jim's hand slid between her legs from behind and stroked softly as Brenda went back to loving her breasts. Then it was Emma's turn to lavish attention on her sister's breasts, smaller than hers, but beautifully shaped with lovely big, dark nipples. She watched as Jim touched Brenda as well, first with his hands and then with his mouth. Emma wondered briefly whether she was going to get jealous, but didn't feel it. These were the two people she loved most in the world, and who loved her the most. It seemed perfectly right that they become connected in this way as well.
