"By the by, Sir Walther, little Ketterlin told me told me what she wanted for her birthday," my fiancee Margareth stated.
I raised an eyebrow, eager to hear her answer, since her sister was ceremoniously indecisive. "Oh? And what might that be?"
"She wishes you to fornicate with her."
I nearly spat out my tea at Margareth's answer, but she seemed unshaken. "She wants me to do what?!"
"Fornicate," she repeated, matter-of-factly in between sips of her tea. "You'll indulge her, right?"
I could only narrow my eyes with incredulity. Such an absurd question could only be some sort of test—that, or she has succumbed to lunacy.
"I'm not going to fornicate with your younger sister," I replied, hoping to stop the matter here.
Margareth, however, was unfettered. "But why not, Walther? Would you really deny a girl's birthday wish?"
"It's not a matter of fulfilling absurd birthday wishes," I retorted, shaking my head. "Do you not see that it would be adulterous?!"
"It is well within the realms of what is permissible in regards to royal law," she answered before taking another sip.
At this moment, I could only stare at her. A solid five seconds passed before I asked "How?"
Margareth smiled. "Is it not true that I am your fiancee?"
"You certainly are."
"Right," she said. "And so, what is mine is yours. And, you do recall that I am my sister's rightful guardian, yes?"
"Of course I do." I could not forget the day her parents passed, making her the head of her manor.
"And so, little Ketterlin is my charge. Thus, by this transitive property of marriage, my sister belongs to you," Margareth surmised.
"I..." By the grace of God, I could not find a fault in her logic. "But why do you want this?"
She pouted in response. "Walther, why wouldn't I want the best for my little sister? The boys at her academy pay her no attention, so she told me she wanted a boy for her birthday, and of course I could only suggest you."
"It was your idea?" I sighed, exasperated.
"Of course!" Margareth beamed. "You're someone I could trust to do it, and besides, you are quite skilled, no?"
Once more, I sighed. What in the world was I getting into?
"So you'll do it, right?" she asked.
Her big, pleading blue eyes peered right into the depths of my soul. No matter how ridiculous of a request this was, I simply had not the fortitude to deny her.
"You win, Margareth. I acquiesce. I'll do it," I replied, leaning backward in defeat. "Just once, though."
"Oh, you're the best fiancee ever, Walther!" she said, flashing me a gleeful grin and taking my hand.

Ketterlin's birthday soon arrived, and we enjoyed the grand celebration and all its frivolities. After the guests went home and Ketterlin retired for the evening, Margareth and I stole away to Ketterlin's bedchamber and knocked upon the door.
After a moment, she answered and carefully opened the door. Her nightgown-clad, small frame peeked from the crack, before opening it fully upon realizing who it was. "Good evening, sister, Sir Walther. What is it?" she greeted, giving a tired curtsy.
Margareth could barely contain her giddiness. "I've got your last present, Ketterlin," she whispered rather excitedly.
Ketterlin looked rather confused for a moment, but her beady blue eyes grew to the size of saucers when she realized what her sister meant. Her hands met her mouth, and her face flushed red. "He's... for me?"
Margareth nodded. "Yes! He's all yours!"
"Just for tonight," I noted.
Ketterlin was practically vibrating with eagerness. She led us inside and sat down upon her bed, clearly unsure what to do.
Unlike her sister, her hair was darker, yet more lush and untameable. Also unlike her older sister's more voluptuous figure, Ketterlin's body was understandably more lithe and girlish. She seemed delicate, fragile even.
Margareth sat beside her younger sister and put her hands on her shoulders. "Just follow Walther's lead, okay? He's very gentle, so don't worry. But if you need something, I'll be right here, okay?"
Margareth gave Ketterin's leg a tender pat, and Ketterin seemed to relax a bit, giving a warm smile.
"Do your thing, Walther," Margareth said to me.
I nodded and
