For this one, i would live in a house or apartment with my twin sister.Im the more shy of the two, and unknown to me,my twin sister is the slavegirl, maid and sometimes ponygirl of a wealthy and skilled master/mistress.
My sister agrees to go with her dom, but is involved in an accident on the way home.She had agreed to be kidnapped by her master/mistress,her idea, and kept shackled and suitably attired during the months that she would be with her master or mistress.
I would look and sound exactly like my sister, but be unable to convince her that im not my sister, as she's pretended to be me before.
Im thinking, i would be kept overseas with my sisters master/mistress for months, or longer even.my sister would be unable to contact her at all.
If this works for anyone, do tell.
