Ok, yes, this is a very messy story, but that makes it so much hotter! I knew my step dad and her step mom would oppose our marriage; those two can barely stand each other ever since high school. Yes, they used to date, and no, it didn’t end well. So we knew we needed a plan, but we didn’t expect my dad to be such a creep and her mom to be such a perv! Better for us, I guess! See, sometimes you just… gotta fuck your in-laws. So, she'll fuck my dad, and I'll fuck her mom. Maybe an in-law swap is what we need to save this engagement...
