Eren.

If there was one thing Rimuru would have changed about the composition of the harem of women present before him, it was the general lack of elves. The Butterflies of the Night in Dwargon was run entirely by elven women, so he knew they existed in this world, but strangely he hadn't yet encountered any outside of that specific establishment.

Hold on, that's not true. Eren's an elf, too, like she showed me back when...no, best not to think of that part. She...well, to be honest, she doesn't hold a candle to the hotties at the...brothel? Bar? Host club? Whatever kind of business that is. Still, she's not bad-looking either, and she's an elf, so she instantly gets points for that. And if she showed up here, she must be interested in me in that way, too.

"Eren, please step forward. And leave your clothes," Rimuru instructed, having adopted a sitting position involving leaning to his right, propping his head up with his arm with his elbow supported by the breasts of the goblinas on his right. His shift in position had changed the placement of his rear on Shion to lower on her back, and had **** her to resist shuddering in delight. His left arm continued resting on the chests of the goblinas on that side, intent to not leave anyone out.

Eren, for her part, continued to find herself bewilderingly charmed by the airs put on by the man - no, slime, she reminded herself again - now seated casually at the front of the room as he continued to display himself to them. Still uncertain about why she'd even showed up to this to begin with, Eren froze upon hearing her name spoken, stuck stiff in the kneeling posture she'd felt pressured to take when everyone else in the room had. A loud voice in her head told her she shouldn't be here, that she should leave, while another voice equally loud told her she wanted this, that she deserved to try this, that experiences like this were also why she had left the Sorcer's Dynasty of Sarion.

"Come on, what are you waiting for?" a voice whispered as Eren felt herself pulled to her feet.

"He called for you, specifically! Lu-cky!" another whispered as she felt herself pushed forward.

The goblinas around her were ushering her forward, offering her congratulations for being picked first, admonishment for her slowness, envious remarks about deserving the honor she was receiving, and other such comments, much to Eren's own confusion. At the same time, they were deftly removing her clothing one article at a time, managing to somehow slip even her footwear and underpants off in between steps. Despite this, she didn't resist, her legs carrying her forward in stumbling, staggered steps as she was pushed and pulled in Rimuru's direction. She saw a grin spread across his ridiculously cute face.

Aww, isn't that cute! The goblinas are helping her out since she's clearly still confused from everything I've been doing this morning. I'm not sure what's more flattering, the goblinas treating being selected by me as such a privilege or Eren's flustered reaction to all this. Whichever it is, it makes me feel like the baddest guy around, fo' sho'!

The next moment, Eren found herself standing before Rimuru, the kind slime she had come to consider a good friend, now nude in human form, and sporting both a beautiful face and a thick, long penis, while she herself was also completely nude. The pink facial markings beneath her eyes could barely be told apart from the rest of her face, such was the intensity of the blush spread like butter across her blank expression. It didn't help that he looked so much like Shizu, another person she had felt pretty close to despite the relatively short time she'd spent with her. The familiarity made this scene feel both weirder and more arousing despite herself.

"Uh...h-hi, Rimuru. N...nice weather, isn't it?" Eren greeted him, suddenly self aware enough to do her best to look at anything else in the room besides the nude slime sitting upon his throne of topless women, but not enough to try to cover herself.

"Well, I see you're still cute and clueless as ever. You heard the announcement I made earlier, didn't you?" he asked, raising an eyebrow. It couldn't be possible she showed up here without knowing...could it?

"Yeah, I...might've heard you say something about, uh...being horny," she answered, before running through her next words rapidly. "And I thought, "wow, that doesn't sound like him, I should go check up on him," and now I'm here!" She was still not entirely certain that was the only thought that went through her head at the time.

"Wow, that's really sweet of you to be concerned about little ol' me! So, do I seem alright to you?"

Eren found herself swallowing saliva. He certainly seemed no different from his usual friendly, cheerful self when he spoke like that. She'd been worried his transformation into a True Demon Lord might have altered his personality somehow, but she wasn't getting any bad feelings from talking to him face-to-face like she would most ill-intentioned people. Could it really just be his horniness that had led to him acting so out-of-character? The feeling of relief mixed with her other emotions, bringing her eyes down to her naked friend.

"I, uh...think you seem okay. I mean, I'm not a slime doctor or anything, but I think you're..." Her gaze fell lower, settling on Rimuru's dick, and her gentle voice dropped low and husky. "...very healthy."

Rimuru's grin appeared once more with the realization that she was just trying not to admit how into this she was, his cock twitching in response to the compliment. "In that case, could I ask you for a favour? Like I said in the announcement, I'm super freakin' horny. I'd really like it if you'd touch my dick, maybe taste it a little. I won't ask you to get me all the way to orgasm by yourself, but getting my dick hard should be doable, right? Oh, and maybe show me your elf ears again while you do it?"

Eren swallowed again, the sight of that thick meat jumping slightly in her vision enough to shatter her delusions about the current situation: she wanted Rimuru's cock. And even better, he was offering it to her. "I'd love to help! Anything for a friend, right?"

Eyes bright and sharp, a smile spreading across her still beet-red cheeks, she lifted her hands to the sides of her head, dispelling the magic that hid her elven heritage, gracing Rimuru with the sight of her long ears. Now that he wasn't despairing over people he loved being dead, he could appreciate a lot more how cute they made her look. Next, she knelt down between Rimuru's legs, letting the heat emanating from his penis warm her face further. She lifted it up with both hands, marveling at its weight; a sack full of silver coins might not be as heavy as this girthy penis! And the way it pulsated softly in her grasp further conveyed its power. Even then it was beginning to expand, her touch alone enough to begin the process of erecting the monolith to its full height, though that was mostly due to Rimuru's pent-up state.

"I haven't really, uh...seen many penises myself, but, uh...I'm guessing this one is pretty impressive?" Eren hazarded to guess, managing to speak through the haze of heat and musk now assaulting her senses as she started down the barrel.

"Of course it is!" came Shion's voice from below, her body shifting slightly as she raised her nose proudly. "It is the penis belonging to Lord Rimuru, after all! There's not a chance it wouldn't be just as spectacular a specimen as he is!"

"Oh...haha ha...hahah...that makes sense, I guess," Eren conceded. She assumed a voluptuous, mature woman like Shion would probably know better than her, anyway. With her attention still locked on the beast that almost seemed to be breathing in her face, she began to move her hands down the shaft, her left hand moving down to the round, equally weighty testicles hugged by his hairless sack. Her right travelled back up the shaft while her left softly groped those testicles, eliciting a moan from above. Pausing to look up, she saw Rimuru's head tilted backward, nearly engulfed in the softness of the goblina breasts serving as the backboard of his throne.

Spurred on by his positive reaction, Eren continued her ministrations, right hand travelling the rest of the distance to the head of the cock and passing over the glans - bringing another cute moan from Rimuru - while her left hand treated his balls to a gentle massage. She'd never seen a penis in person before, but she had learned about the anatomy most humans and demihumans shared from biology books, so she knew generally where the most sensitive parts were. She considered it a lucky break that Rimuru was imitating that anatomy so well. Although, considering what he'd told them all about having been human living in another world back when he was preparing to face the Falmuth army, it made sense he'd be familiar.

Being a virgin myself, I can't really judge her performance, but this feels pretty damn good for someone who claims to have never seen a dick before! Elf girls really are the best! Her hands are so soft and smooth, and what she's lacking in va-va-voom she makes up for by being so damn cute! I mean, who shows up as part of a harem, walks up to a fully naked guy, and talks at him like it's an ordinary day? Fuuuuuuuck!

Rimuru's pleasure continued as Eren pumped his cock, quickly learning to squeeze a little as her hand passed the rim of his head on her way up to the tip. Before long, she had switched to using both hands to pump the now fully-erect cock, the **** of her jerking causing Rimuru's balls to swing and bump Shion's midsection with the same rhythm. Shuna and the rest of the women watched and listened as the foyer was filled with moans from both Rimuru and Shion, none daring to interrupt or attempt to join in without instruction from their lord.
