Nyarly, Kuno swapped places and let me play the mother, Wolfy wrote in a second older sister. Your older sister Rachel is 17, Kuno's
older, older sister Sarah is 18 and the twins are 16. Oh and Crazy Ivan's older brother Michael is 20.
Mum and Dad have been busy

I wanted to ask are you okay with that? Mom can still do D/s play with Rachel (or in fact anyone, it's her hobby).
EDIT: The two older sisters could be 18 and 19 perhaps?
