One day at lunchtime I met them heading for their room and they had a couple of bottles of wine, after a bit of chat they said to come up and see them...later. After 5-6 pints I decided to get a carry-out and go and see them, I knocked on there door and a robed Yvonne answered and she looked a bit merry with the wine, she let me in and went to the roof terrace where Anne was. Anne was topless and got up to pour me a drink while Yvonne took her robe off to reveal her tits. Now Anne was a big woman. “Jeez Beth, how can you do stuff like that with your brother. You do know that’s incest.”All of a sudden I didn’t think this was one of Beth’s best ideas.He is my brother and the only guy in this world that I trust not to hurt me, force me to do something I don’t want to do or brag about what we do. We started doing it long before I met you and we never stopped.I could see Barbara was a bit upset with Beth but her curiosity was peaked when she asked, “Just exactly what do you do with each other. His thoughts wondered as he gazed at her body. It was not long before he was quickly snapped out of it though. He realized she had moved closer to him and was now pressing against his bare chest. He felt the lace of her bra against his skin, her hands rubbing his shoulders and back. He moved his own hands to her body in return. He then began running both hands to her hips and then up her body. They caressed each other sensually before finally they could not take it any more. Slowly pulling. "And besides, you're not technically naked; I can't really see anything." I had an odd feeling she was trying to. And then I realized my breasts weren't very well covered, and she must have, too, as her eyes widened as she said, "Omigod, your breasts... they're-"I grew red with embarrassment. "I know, really small," I muttered. "Well, yeah," she said. "But that's good! I was gonna say they were… gorgeous."An odd feeling grew in me... almost like the day before. "Gorgeous?" Yeah," she answered..
