We just got back from our parents’ wedding. Now we’re step-siblings. Both in our 40s. Both pretending the tension between us wasn’t real. She was still in her dress, a little tipsy, asking me to take her home. I should’ve said goodnight. But when she looked at me like that… I couldn’t leave. This is a real couple playing out a filthy, forbidden fantasy. We take our time building the heat—teasing each other, kissing slow, undressing in pieces—before it turns into deep oral, moaning, hard thrusts, and raw fucking that neither of us can stop. She calls it wrong. I call it mine.
