Life of a 13 year old- Make your sister into a sex slave
You come up with a great idea as you watch your sister laying in a puddle of your cum; if she likes being fucked by you so much, why don't you make it a regular thing.
You bend down in front of her and grab her chin, forcing her to look at you.
"Now listen up, sis. I know you enjoyed what just happened, and I know you don't want mom to find out, so I'm going to tell you how this is going to work: You are now my bitch, got it? If I want sex, you give it to me. If I want head, you suck until I tell you to stop. Ok?"
She opens her mouth to protest so you shove three fingers in her ass. Her eyes roll back into her head and she moans while she nods at you. You look around for a moment before finding a pair of pajama pants; you pull the drawstring out of them and tie it tightly around your sister's neck. You tug on it and her eyes bulge, she reaches for the string but you smack her hand.
"If you don't want to choke then you had better keep up. C'mon, whore, follow daddy."
You pull the rope again and she climbs out of the bathtub. You point at the ground and she gets down on her hands and knees and follows you back into her bedroom. You tie the other end of the rope to a bedpost and start going through her drawers. You find a buttplug, nipple clips, an 18" vibrating dildo, and anal beads.
Which do you use on her first?
