I agree with the ideas about adultery but I think everyone is taking the death part too literally.
"so we drowned him in the pool, her in the ocean
Bury the bodies in a park just down the street
and then crawled back in bed"
I think it's a metaphor. By cheating they are "killing" their spouses, like breaking their hearts.
Also, in the end the line about getting high. I think it's like getting high off the thrill of cheating.
"I've been getting high. And she breathes just like i do"
I think the "breaths" are sexual and they are equally thrilled by the recklessness of cheating.
