You and your stepsister pretended to be a couple in order to deflect unwanted suitors while working at the Renaissance Festival. But after a drunken party one night, the line between the characters you play and your real selves becomes permanently blurred.

The Ren fair is a fantasy world in your own backyard, with elves, vampires, and Witchers everywhere you look—all people in elaborate cosplay. You're dressed as a knight with a sword, while Moon wears a revealing pink and white dress with fake pointy ears as a British elf, her cleavage prominently displayed.

Present night

You two wave goodnight and head back to your grandparents' RV they lent you. "You know, everyone thinks we’re going to have sex now," Moon laughs, her arm wrapped around yours. You've perfected your fake flirting over the summer.

"I know I’m your sister. You know that too. But we never told anyone else at the renaissance festival that. We let them think that we were just a regular guy and a girl so that no one would hit on me while we worked here. Other college students working here respect that we're 'boyfriend and girlfriend' and don't bug me. Or maybe they're just afraid of you and that sword you carry."

Moon chuckles, "I did kind of forget how cute the guys looked in their outfits and armor though. All the accents, and the role-playing. Dressing in this outfit, showing so much cleavage... it always makes me feel sexy. And I do have the perfect little love nest here. No tent for me!"

She checks her watch, "Look at the time. That's when we do our act at the mead stand. The evil nobleman tries to kidnap me, you jump in with your sword, we fight, you disarm him, I hit him with a turkey drumstick, then I kiss you. Everyone applauds and the tips pour in."

"Remember when we first started? I'd kiss you on the cheek with my lipstick. Then someone yelled for a real kiss. The crowd joined in, and you always give them what they want. So I did too, and they went wild. The tips got better, and it helps maintain our story. It's only for a few more days, and it's not that weird if we're in character when we kiss."

Moon looks at you with glistening blue eyes in the moonlight, "We're both drunk, and a little high. I gave you my best sexy voice and bedroom eyes when I asked you to take me back here in front of everyone. I had to give a good reason to leave."

You reach the RV and she switches to her British accent, "Thank you for saving me, good sir. That cad would have carried me off. I am so grateful. Unfortunately, I have no money to reward you. Can I reward you in other ways?"

She chuckles, "God this is crazy," then continues in character, "You could claim me as your prize right here in your strange wagon. Perhaps when the nobleman hears my cries of pleasure echoing across the village, he'll be reminded of all he has lost today."

You help the slightly intoxicated Moon inside the RV and lay her on the bed. Her normal voice returns briefly, "Thanks," before switching back, "But before I drift to sleep, give me a good night kiss. Like the one after you saved me. Please, good sir... do not make me beg."

You reluctantly give her a kiss on the cheek as her stepsister. "Thank you, my knight. Oh. I wish you would have accepted my offer earlier. You have set my heart aflutter. Here, feel how it beats so rapidly under your hand. And if my hand slips, and moves your hand directly over my breast next, then who-"

She cuts herself off, accent disappearing, "It's okay. Don't break character. Just a little more role-playing, please? It's just my tits. Work with me here... you're an actor, just like me. It's ok, our characters aren't related and neither are we. Remember, I'm your STEPsister."

Her fake British accent returns, "Go ahead and squeeze it through my bodice. You caress so gently when that man would have pawed clumsily. Now kiss me again."
