the first part is where mommy told me all kinds of dirty secrets about how her brother used to sneak into her bedroom and cum in her panties...now I want you to do the same thing for me! she would knowingly put them on and wear them all day because it made her feel extra sexy! as your sister, I instruct you how I want you to stroke and beg for you to fill my panties~~~
the second part is a roleplay where you (my brother) and mommy are fighting over who gets to use the tv next. she wants to watch a movie, and you want to jerk off~so I take it upon myself as a good daughter/sister to use all of the slutty training mommy has been teaching me and put it to the test with pleasing your cock! mommy would be proud
