You sure it's a pork tenderloin? Or is it a pork loin? There has been confusion about that here in the past.
This is what I do a lot of the time. However, if you insist on doing it yourself, try fucking it and filling it with semen. Then, go ahead and feed it to the whole family, all the while laughing, because YOU know. If your wife had agreed to anal sex last night, they would all be eating good pork, but NO!!! They're eating your semen. Your wife must be a real bitch to do that to them. I feel bad that you have to put up with that on a daily basis.
