10 White Demon's Night (R-18)

As soon as the door closed, Hinata practically pounced on Rimuru, her tongue greedily finding its way into his mouth, quickly familiarizing itself with it along with his own tongue. Before things could get too out of hand, as this was supposed to be Testa's night and he'd rather not have a threesome with it being her first time, he pried Hinata away from him.

Hinata pouted. "What? I can't kiss you after not seeing you for a week?".

"Your hand was over my pants."

"… So? Oh, right! This is Testa's night. Go ahead. I'll watch."

She promptly sat down on the chair near the bed with eager eyes. Rimuru realized that a week away from him or any of her "sisters" drove her sex drive through the roof, and so before she could direct the pace any longer, he created a double which promptly grabbed a now predatory looking Hinata and teleported to her room.

Testa watched the interaction play out in under thirty seconds with wide eyes and a blush before coming to the fact that they were alone now.

*Oh god, this is really happening, isn't it? Should I move? Should I wait? I remember overhearing Shion arguing with Shuna about how best to please Rimuru-sama… Should I just start taking my clothes-?*

"Mmph?!"

She was snapped out of her thoughts when Rimuru went up and kissed her, this time far more assertive than he had before. The nights they spent inside their room before were very tame. They never went to sleep without kissing, but it was always far tamer, followed by them soundly sleeping in each other's arms.

It was certainly different than this… this raw passion that he took her lips with. It was crystal clear that he wanted her. Badly. Maybe this past week has been just as rough for him as it has been for her. And this was true. Ever since he first had sex with Ciel, there hasn't been a night that passed where he wasn't having sex. Though he hid it as well as she did, it was all coming out now.

As their tongues were intertwined, Testa wrapped her arms around him, one grabbing the back of his head while the other grabbed his waist. Both of his hands were grabbing her ass and he slowly guided them to the bed where they fell back on.

Once there, Rimuru rolled them over so that he was on top of her, and his hands moved away from her butt. His lips moved away from hers, and she noticed that her heart was beating rapidly, and she was breathing heavier. Taking note of Rimuru, she was also aware of his frame. He was ever so slightly shorter than her, and due to him taking Shizue's body he didn't create the most overbearing sight. Yet him kneeling on all fours on top of her with his hair draping like silk near her face was by far the hottest thing she has ever seen.

And he was still fully clothed.

"Before we continue, I want you to remove all your natural resistances. I want to give you the best experience I can."

She gulped. "… Okay."

Though she wanted this, she started getting afraid at lowering her resistance, at being so naked. No matter where she went, she always had at least some sort of barrier or resistance active in the incredibly unlikely event that she was attacked, and Rimuru was asking her to surrender everything. He took note of her apprehension and started to gently kiss her again.

That wasn't what she was here for. She berated herself for even thinking that he would take advantage of her.

Softly pushing him away, she said with a look of steel determination, "Rimuru-sama, I trust you with my life. Though my body is yours to do as you wish, I'm a strong demon. I won't break from something like this."

Rimuru was slightly surprised at the strong declaration, but then smirked. "We'll see about that."

Sliding a hand under her shirt, he pulled it above her breasts, exposing her lacy red bra. "You've been hiding this from me all this time?"

She looked away in response with her face getting far redder, with her blush slowly finding its way down to her neck and beyond.

He reached behind and deftly undid the clasp that hooked the bra on her, drawing it away and letting it fade into magicules that went back into her. What remained were an amazing pair of porcelain-colored round breasts that were supple to the touch with beautifully crafted pink nipples proudly showing off to him.

This is where his characteristics as a slime started showing off. Putting one of the gorgeous pair of boobs into his mouth while grabbing the other, he let out lubrication to make them easier to play with. Rolling one of her nipples with his tongue while pinching the other and grabbing her breast, she started to stifle the moans with her hand.

"You can let them out, you know. I'm sure you detected the sound barrier I put into place."

Testa bit her hand harder at the comment, and Rimuru took it as a challenge. He started being more aggressive in his movements, alternating between breasts, grabbing her breasts harder, and lightly biting around each nipple. She didn't even last a full minute before light moans could be heard around the room bringing music to his ears.

Rimuru raised his head to look at her, basking in her beauty and staring deep into her scarlet eyes.

"Raise your arms."

She did as she was told, and he pulled the shirt off, leaving her completely topless. He then lowered himself down to her breasts along with his hands to her sides and started gently tracing his fingernails down to her waist, all the while maintaining eye contact.

Her hands reached down by instinct to her pants, but he forcefully pinned her hands together with one of his, while the other reached around to the back of her waist and started pulling down her pants. She raised her hips, and he tore off her pants, leaving only the lacy red lingerie left.

He took off his shirt and sealed her lips while his hands moved down and traced along her underwear, before sliding into her underwear and raising his hand, causing it to disappear into magicules.

His hand went back down and started rubbing her mons pubis, and Testa slowly felt a surge building up in her core. Rimuru pulled his lips away from hers and she tried covering her face with her hands, but he grabbed and held them above her head.

"Wai-! Rim-! Ah!"

"I want to see your face."

She tried her best to look at his face, even as tears started forming in her eyes.Her breathing got more ragged, and her body started quivering as the pressure continued to build up in her core, before it suddenly stopped.

She looked at him as if he had just taken the thing she wanted most out of this world.

"Please! Please, I want more!"

Rimuru grinned, showing his canines. "That's a good girl."

Patting her clit a couple times causing her to shake madly, he went down and kissed the top of her vagina. Once he was comfortably between her legs, he wrapped one of his hands around one of her legs and with the other, inserted two of his digits into her walls. Quickly finding that magic spot within her walls, along with him sucking her clit, she started thrashing and her juices slowly came out of her. The squelching sounds of him moving his fingers around in her and her moans, now completely unrestricted, caused the pressure she felt to compound before it finally broke through.

"Rimu-! Ahhhhhhh!

Pleasure skyrocketed into her head and throughout her entire body as she was shaking uncontrollably, her juices flooding out of her drenching Rimuru.

Rimuru wiped his chin off and took the rest of his clothing off, now completely naked with an erection. Testa looked eagerly at his length and was prepared to get up and service him before he held out a hand.

"This night is completely about you. Lie back down and relax. I promise you'll enjoy it." He added the last line with a smirk.

From prior experience, Rimuru had reduced his length as he found out the hard way right after Shion that most women, unsurprisingly, don't enjoy their cervix getting smashed in by some gargantuan penis. Of course, as most of his sexual knowledge before having sex was from hentai, he genuinely believed that bigger means better.

When he found out that Shion was in pain, and that Shuna just grit her teeth to please him during their first time, he felt like shit. Cursing hentai for giving him poor sex knowledge, he changed his length into a more manageable 16cm (6¼ in.) Still above average, but no longer uncomfortable and painful. Besides, it could always be adjusted for each individual woman's length.

As Testa lied back down on the bed, he positioned himself at her entrance, sliding it over her clit once times, two times, three times, before putting the head into her. As expected of a virgin, despite a decent amount of foreplay, she was still tight, but incredibly warm.

Testa was prepared for him to bury himself to the hilt, so when he just put the head in, while still felt happy, she looked at him a little confused, thinking that he was still teasing her. When she saw that he had a look of happiness along with one of mild concern, she couldn't help but think, Such a worrywart.

Giving him one of the most loving smiles she had, she opened her arms to him, only to have him enter her more and pin her hands above her head while his face was meeting hers.

"I love you, Testa."

"I love you too, Rimuru-sama."

Sealing their love with a kiss, she tasted herself on his tongue, which tasted like red grapes, albeit slightly bitter.

Rimuru let go of her and moved back to a more upright position before grabbing her waist and setting a punishing pace.

Testa was shocked at this, but she craved it, needed it, so much that her moans immediately started up again and were melding with Rimuru's grunts. Her breasts were bouncing freely, especially with the occasional slap that he was giving them, causing her to moan louder than normal. Her hands found purchase on the bed post where she was holding on for dear life, trying to not completely lose herself in carnal pleasure.

He soon found the exact length he needed to reach that sweet spot where it reached the deepest part without grazing her cervix.

"Rim-! Ah! Plea-!"

She started rambling incoherently at the added pressure to her depths as he mercilessly attacked her sweet spots with pinpoint accuracy. Any semblance of the prim and proper primordial demon she was known to be was completely shattered by a demon in heat moaning and panting for a sweet release.

"Rimu-! I can't! Ah! Hold on mu-! Much! Longer! Hah!"

He put a hand on her clit in response and lightly rolled it in his fingers before he felt her walls spasm all around his cock.

"Fuuuuuuuuuuuuuck!"

As she was cumming her brains out, Rimuru was still locked inside of her as her vagina was desperately trying to milk him. Unfortunately, if she wanted his tantalizing liquid, they would need to go for at least one more round.

Testa came down from her immense high and was exhausted after having cum extremely hard twice. Feeling him still inside her, she did a kegel and then noticed something… missing.

*Has he not cum once yet?*

Even though she was now officially his lover, her service-oriented mentality prevented her from letting him leave without finishing once. Sitting up and reluctantly removing him from her, she was prepared to fellate him before he once again stopped her.

She questioned this with a slight fear that maybe she wasn't good enough to service him. "Rimuru-sama?"

"Turn around and point your ass towards me."

This time, Testa was fearful for a different reason.

*I might not even be the same woman once he's done with me…*

Though that fear quickly turned into excitement when she turned around and he slapped her ass. Positioning himself back to her entrance and immediately plunging to her depths, she let out a gasp and a moan as he pushed on her shoulders to make her collapse onto the bed.

Lying down on top of her, he continued with slow, deep thrusts that were at a new angle to her and one that she couldn't get enough of. Especially on top of the tiny electrical shocks he was sending throughout her body which constantly threatened to drive her over the edge, but always stopped right before.

"You are MINE!" he growled into her ear. "From now on, everything. Your eyes, your hair, your ass, your pussy, your body, they are all mine!"

Testa was barely coherent to hear what he had to say, much less respond back.

"Yeff! All youh-!"

She was slowly losing power in her extremities as another orgasm formed, making the others seem like drops in a bucket.

Rimuru quickened his pace, and with her completely giving control to him, refused to let her cum until he was ready.

"Testa! I'm about to!"

<<I don't think she can even hear you anyways. Fufu>>

Rimuru pulled back so that the head was barely inside of her before thrusting it all in and unloading his seed completely into her while biting right below her ear and timing each of his spurts with his thrusts.

Testa came right as he bit her and, instead of an earth-shattering scream of pleasure, there was nothing outside of the quiet convulsions of someone who seemed to be twitching in their sleep.

Once Rimuru was done finishing inside of her, he noticed that her eyes seemed to be completely glazed over.

Ah. I overdid it again. Hahhhh

<<Rather than say you overdid it, I believe this is a result of you keeping it in for such a long time. Either way, Testarossa is completely satisfied.>>

That's called overdoing it. In any case, will she be all right for her trip tomorrow?

<<Fufu. Perhaps if she chooses to resume her nullifications. But with you marking her, I doubt that she would do such a thing unless you ordered her to. I can only hope that the horse ride won't be too punishing on her sore vagina.>>

*Hahhhhh…*

Rimuru laid on top of her for a moment before pulling out of her and cleaning her up with magic.

When he did, Ciel came out and rested beside him.

*I promise to make it up to you soon.*

<<Oh, please don't worry about such things. You currently are.>>

Rimuru suddenly remembered his earlier conversation with Hinata and paled. Connecting senses with his other self, he found him in a threesome with Hinata and Ciel. Ciel was currently sitting on his face while Hinata was skillfully riding him and kissing her. What made this scene truly staggering was that his arms and legs were bound with Sticky Steel Thread and Ciel was preventing him from reaching an orgasm until it was borderline explosive before they would start over again. Currently, he was at two, and the two women showed no sign of stopping anytime soon.

<<The memories will be spectacular once you absorb yourself, master.>>

Perhaps connecting senses was an ill-advised decision, as he was now at full mast yet again.

<<Please allow me.>>

*Have I ever told you how much I love you?*

<<Exactly 3,951 times. Now, please rest and enjoy my service.>>

*After you're done, rest with me.*

<<As you wish, master. No more talking now.>>

As Ciel was suckling him and cleaning off his member, he wrapped one arm around Testa, cuddling her, and simply enjoyed the view. Starting tomorrow, they were going to be separated for at least a week unless Hinata and Testa could get some alone time to fool around with him. With that thought in mind, and Ciel's ass next to him, he drifted off to sleep.
