Stiefbrudchen im rücken

Our parents are out of the house for the whole weekend and I am so bored! My stepbrother is chatting with his "girlfriend" trying to get into her pants... She totally doesn't put out for him nearly enough. I bet he is so backed up. I should try and play with him a bit. I've thought about what he keeps in those pants often enough. I wonder if he has thought about his stepsister sucking and fucking him. I wonder if he has considered how much better I would be than his lame girlfriend. With my lips wrapped around his cock he would forget about her in an instant. Maybe he needs a glimpse of what he is missing out on. I just want to see how big he is. Maybe feel it. Just as long as things don't get carried away. He really shouldn't cum in me...
