Des:I didnt know...that my younger sister had such a big bust...When I was watching her play the keyboard harmonica, I noticed that her lips holding the reed in her mouth were extremely erotic, and when I saw her lips wet with saliva, my dick was in her mouth. I couldnt hold back and attacked her because I imagined her being so angry! And then, I was so excited about her breasts...they were huge breasts! My cock is running wild!
