You know exactly what to do from the start. You decide to merge with both of them, keeping your "new life" as a rich dude as dominant. You want to keep this filthy rich life after all. Also while you're at it why not give yourself the sensitivity of both their bodies combined ?
You invite them to come closer and as they do you use the device. They are suddenly sucked into you.
Moments later you are overcome with intense pleasure as you are overcome by just how sensitive your turned out. You moan in pleasure, this is what you wanted.
