My brother, Luke, and his girlfriend, Maddie, stayed over for the night about a week ago, as they were staying in town for my uncle's funeral. At about ten, I decided to go to sleep, so Luke and Maddie also went upstairs and into the spare room. I awoke at about midnight in the morning to a pair of big tits in my face. Maddie was in my room. She said that she was more attracted to me than she was to Luke, and when I said I didn't believe her, she said she'd prove it. When I asked how, with one hand she pulled down her pyjama bottoms, and with the other hand groped my dick through my boxers. When she did this, I smiled, and she then lifted up her top to show me her massive tits. Considering she was about five foot five, her tits were massive in proportion. I was sucked in by this, and spent the next half hour or so giving her the ass-fucking she deserved. She was incredible, and I truly mean that. After about two hours of peaceful sleeping, I was awoken again, this time by my brother. Over the years we spent sleeping in the same room, I was awoken many times during the night, as Luke doesn't seem to realise that other people need sleep. Anyway, he was confused as to why Maddie didn't want to have sex with him. He also doesn't seem to realise that other people might not be interested about his sex life, but Luke's Luke. I said I didn't know, but he said it was probably something to do with his small dick. I asked how small, and he said it was about 6 inches. I said that wasn't particularly small, but he insisted it was. I told him to show me and I'd say if it was small. He flopped out his dick which was clearly more than 6 inches, and he saw the smile on my face. He pushed it towards my mouth, which I gladly sucked until he came. He then took out my dick and, after caressing it a bit, he pulled down his boxers and sat on it, taking my 8 inch dick all in one go. He felt so good on my dick, he felt nearly as good as Maddie. After I came his ass and had/gave a couple of blow jobs, he went back to his room. I slept soundly after that. In the morning, at breakfast time, it was quite awkward, considering both halves of the Luke/Maddie relationship had had sex with me overnight, but I made it through. Just. When Luke asked if Maddie had spoken to me about anything, I said no, but I think he might have got a hint to what happened... Luke continued dating Maddie, and when he went away with work a couple of times, I got to know Maddie a bit better, if you know what I mean.. :)
