Make her the family sex slave
From Torg Adventure
"I'm glad that you are willing, sweetheart, to do anything I ask."
"Oh yes, Master! I want to serve you."
So pleased it seems to be working, I say, "I love you for that, Sweet One, and I want you to listen. If we are with the family, and I whisper 'whore' and say something to you, you must do what I say. If we're with your mother, if I ask you to strip or to kiss her or to lick her... what will you do?"
"OH Master, if you call me 'whore' I will strip and kiss and lick."
"And if grandpa is there and I tell you to suck him...."
"Oh, yes, I will. Anything, Master, to please you."
"Now come and bare your breast to me, mmm my yes, beautiful, and so firm. Now lets go into the family."
Who shall he try her on first?
