A lot

They both walk over to you with wide smiles on there faces as you enter the house

"We missed you" your sister says seductively as she rubs your crotch

Your dick hardens under her gentle rubbing, "i have gifts for you" as you open the bag inside it is there is some ropes hand cuffs chains and many other things but the items you were looking for was none of those

"Aha" you exlaim as you finally pull the objects out the bag

There they were two black collars and leashes

"Obey From now on you will walk on your hands and knees when wearing this collar if you have to reach something you may kneel, understood?" They both nod

"Now time to put them on" you reach over and secure your mothers collar around her neck firmly and watch as she sinks to her knees you give her a smake on the ass to which she moans

Now you move over to your sister but this time you grab a handful of her breast and twist her nipples causing some milk to leak "ayaan" she moans then you secure her collar and watch as she joins your mother on the floor
