Now that you have had MIL's 3 holes what is next? A light spanking might be in order, or light bondage.
First time anal doesn't go quite as easily as you describe. Through the years, I have had the honor of deflowering several butt holes and it is never as easy as that. One has to use a lubricant, Astroglide is the best. After a couple of repeat performances, the woman will tend to relax more and you can get in easier. But still, for her to be comfortable, use the Astroglide.
I think you should KILL the Mother In Law, and then cut off her ears and have sex with them.
Or, they could go camping....
