I hate have sex with my wife. It bores me to death. It feels like running on a treadmill except this one is killing me instead of making me stronger.
Too bad. Try this. Mount her from behind then say, "This is how your sister likes it." Believe me, the next 60 seconds WILL NOT be boring!
Yee Haw! Ride 'em cowboy!
I hate having sex with your wife too, she's not very good at it.
Start fucking her ass and tell her you can't do it any other way because you are a butt pirate.
She feels the same about you. your loving wife
