His shirt looked better on her than it did on him. She was barefoot and seeing her tiny little feet, made Zack groan. The shirt did justice to her bod.... The top two buttons were undone showing her ample cleavage. Her hair flowed onto her shoulders, making Zack want to run his fingers through it. Her milky white thighs were exposed, making Zack remember how they were wrapped around him, the previous night. The shirt was long enough but not too long. Zack didn’t know whether she was naked beneath. Are you wearing panties?" Panties? Look I just threw on whatever was on top of the drawer only because you're the one who is uptight about her body." What? I am not up tight; I just don't think I should be walking around naked in front of my brother." Sophie, I am your brother, you are my sister. Just because you happen to be inside my body, doesn't make it weird. Well, it's weird but not that way. I don't know what the fuck I am talking about."They both cracked up laughing and they hugged each. I walk over beside her and lean in for a gentle kiss... well it was going to be a gentle kiss. But when I leaned over she grabbed me around the neck and pulled me on top of her and we embraced each other as we kissed passionately. Within minutes she had taken my shirt and sweats off and we lay naked holding each other. She then rolled me on my back and told me to relax and not do anything, I was skeptical at first but that soon changed as she ran her hands in my hair and started to kiss my. She came out just as I was finishing up with a glass of ice tea.I noticed right away she wasn't dressed as usual, she had on a tee shirt and sweat pants.I could tell she didn't have a bra on by the way her tiities were jumping around when she came walking across the yard.Her tits hung down very low, but I still checked them out.We chatted a bit then I headed home to do some stuff at my house.Didn't give her another thought the rest of the day.Later that afternoon she called over and ask me to.
