Karina and MoRina have a long-standing stepsibling rivalry and disagreements are nothing new. These mature step-sisters are barefoot, dressed in yoga pants and camisoles with no bra because they just finished a nice yoga session. Apparently it didn't do a lot to chill them out, as they get into a knock down drag out argument over Karina revealing that Grant asked her out. There's some serious jealousy and possessiveness going on and the two step-sisters whack each other and trash talk, humiliate, poke, grope and prod each other while they are laying limp. Grant comes in to find Karina kneeling over a limp MoRina, making excuses about their little catfight. He can't resist whacking Karina who falls on top of her step-sister. Grant decides he needs to change his date with Karina a little to include the two limp ladies....
