Alright, how about this scenario then.
Let's say that while in university, you agreed to a cloning experiment for spending money. A few years later, you get into a terrible head on automobile collision, due to your own fault (you were fiddling with a cell phone while driving, let's say). You wore your safety belt and you are fine, if not a little dazed. The other driver, however, was thrown through his windshield, and is on his back, twitching in the middle of the road.
You get out of your automobile and see that it is your clone. You are shocked, and you feel a sort of natural father-like empathy with your clone, even though you did not know him that well. Your clone is dying, and he indicates that his last request and lifelong dream is to cum as he dies. Since both of his arms are broken, the fulfillment of his dream falls on you, his brother/father/source. What would you do?
