Give her her boyfriend's dick back.

You don't want to be too cruel. After all all they were ready to fuck and you wouldn't want to stop them doing so.

A quick run to you sister's room give you one of her hairs to put in the device. (you carefully keep Chad's pube, you never know when you might need it.)

After a few seconds looking at her naked picture you click her pussy and replace it with a dick and a large pair of balls.

You get in command mode to choose horny and fuck.

You switch back to Chad and add submissive and very horny to his setting.

You think a little and try just how submissive he is. You grab your phone and call him as you boot up your computer. You launch Skype and pick him in your contact list.

"What do you want? " he asks as he picks up the call.

"accept the call on Skype on your computer and make sure the camera has a good angle on your bed. It is an order." you bark at him. You expect him to tell you to go fuck yourself, but a few seconds later your screen shows you his room.

You can see your sister lubing a 10 inches cock on his bed while calling him.

"Come on little bitch, let's put this pussy of yours to good use. I don't know what's happening but I can't pass on testing how it feels to be on the giving end. " she orders him.

"Of course love, whatever you want darling!" he replies as he go lay on his bed offering her his virgin pussy.

You watch with amazement as your sister rams her dick in his small pussy making him squeal. You had made sure to record it of course, it would be good **** material and a few sites would give you good money for that.

You realize that you could make awesome porn videos with this device, changing people to become all sorts of fantasy or Sci-fi creatures with actual working parts rather than cheap make up.

You sister has finished already as you reflect on that and moved to making Chad suck her dick to clean it.

"So just how easy is that? You never believed me when I told you it was hard to breathe with a dick in your mouth, maybe now you will understand. Or should we try your other little fantasy, we can try anal today if you want, we can do it as much as you want. " she taunts him joking about his obsession with anal sex. She probably wouldn't do that.
