So I get a call today from Kamarie telling me I needed to come back over. When I get there I see her in her bedroom dressed in a sexy red nighty. I quickly asked her if she was wearing that for me or my brother. She told me that it was for me because the samples are not working and we really needed to do it the old fashioned way and she figured the outfit would help. I didn't know what to do I couldn't believe I was standing in front of my sexy sister-in-law who is asking me to have sex with her. I was so hard I couldn't say no so once again I agreed to help her out. She started by giving me a great blow job. I really liked the first one but this one was better way better I could tell you was enjoying this just as much as me. That's when she straddled me I could feel the heat and wetness of her pussy touch the head of my dick and then I was all the way inside of my sister-in-law!!! We fucked like in several different positions until I flooded her pussy with my cum there was so much you could see it coming out when I pulled out.
