"Shuna, you're not making sense," Shion said. "Surely you don't mean-"
"Yeah, we're going to use that magic. I can't wait to… pleasure him, and you too, for that matter," Shuna giggled.
Shion shrugged. "You always were a tomboy. I kept wondering why you'd recently become so shy. But I suppose you didn't. You were just hiding that, weren't you?"
Shuna winked and started mumbling something. Her body radiated heat and a minute later she moaned as a bulge formed on her skirt.
"Shuna?" Rimuru mumbled. "That's… what's that?"
"You'd like to know, won't you? This is the secret passed down only to the maidens of the royal family. Shion knows because I've told her but no one knows- not even my brother."
"Things I do, sigh…" Shion meanwhile went to the door and started fixing it.
Meanwhile, Shuna undid her lace and the skirt fell down. Her dress merely hung on her body but not for long, that too fell. Only underwear remained.
"That's…" Rimuru mumbled looking at the wet patch on Shuna's panties and also the stuff poking out from the sides. "You have a dick."
"Yes," Shuna said. "But it's a magical one and doesn't produce semen. Disappointed in me?"
"No," Rimuru gulped, and slowly… slowly slid Shuna's panties down to reveal her soaking wet pussy and that long hard cock. It was about the size of his own. "My-my body feels weird."
These last few days he'd been at it so much that his mind lost control. His body was flooded with feel good hormones and wanted to keep feeling that. To do so- with the same intensity no less- he had to do novel and novel things. And right now-
Shuna's dick was perhaps the novelist of things- and… and… "MMh!" Shuna moaned as a warm yet wet sensation spread on her cock. A slightly warmer soft thing was pressing on her junior's top and wrapping around it, almost sucking on it- "Oh yeah… I forgot how good this felt!" She almost instinctively dragged Rimuru's head and pumped him.
But… but she tried her best to be civil and not Scare Rimuru. After all, this was his first time. And she had to be gentle.
"Funny how roles change," Shion mumbled taking a seat on the bed.
"You can join us too you know," Shuna said. "You can take him while he sucks me."
"Not in the mood to lick pussy. I could finger his ass though," she smirked.
"I wasn't talking about that," Shuna mumbled through the moans and pants. "How about I cast it on you too?"
"You mean, me growing one? But… I mean… okay."
"Excellent. Ah…! Oh wow!" Hot liquid pleasure welled inside her, oozing out of the tip of her member, thoroughly expulsing everything in Rimuru's mouth. "Do be a dear and drink it. I promise it's better than anything you've tasted."
Rimuru's mind was sort of melting but he obliged and drank the slightly salty, yet somewhat sweet drink. It wasn't anything remotely like semen; didn't smell like semen either but smelled like anona fruits instead- something like a cherimoya; milky. "What is this?" He managed.
"My honey," Shuna mumbled, but she was getting harder by the second. Meanwhile she also mumbled something and Shion's body burned.
It burned and burned and all the heat traveled down to her crotch and- "AH!" She nearly came or so she felt but a bulge manifested. Shion gulped. I can finally…. Fuck him too? She licked her lips in anticipation.
