Darkness wants more, Kazuma's a snore

He nodded but still seemed a little nonplussed. "It did feel pretty good for a jerk off session, thanks for making me use your mouth. Way better than a sock, you were right."

I took another big breath of air, still coming down from my high. He went to raise his trousers up but was met by resistance when I grabbed his waistband.

"If you liked it, we could… do it again?"

"Nah, probably not. I try and only do one jerk off a night these days. Less likely for one of you guys to burst in while I'm whacking it." He said abandoning his pants in my hands and standing up to stretch his back. Big dick swinging back and forth in front of me temptingly. "Besides, after a load like that I'm gonna need a little time to recharge."

I frowned. I had a feeling these earrings may have something to do with this. Since it was normal for me to be here I guess there was no reason for Kazuma to go out of his way to impress me. The only reason he did anything sexual to begin with was because he was already doing it when I walked in. If I didn't change anything I'd be doomed to having to wait around until we could have fun again when he happened to be in the mood.

"Kazuma. Without it being a problem for you at all, it's normal for your balls to fill and you to be able to get an erection whenever you… or I want you to."

He just chuckled. "Man those earrings Vanir gave you still only make you able to say true things huh? That demon is so annoying sometimes. But yes, sorry to say I don't really want another boner just yet."

My eyes were glued to his swinging dick at this point. "I do. I want you to have another boner."

The effect was so quick that his cockhead nearly gave me an uppercut.

He was once again breathing raggedly, "Fair enough." His hands were twitching almost as much as his penis, instincts to stroke himself being overridden by the curse. "So where should I jerk off now? Your mouth again?"

The power I had over Kazuma was intoxicating. It wasn't like I was directly controlling him, just winding him up and making him use me as his rag.

"Fuck-I mean, jerk off with my tits Kazuma!"

"Yes Ma'am."

He again didn't wait a second. Hopping off the bed and ramming his dick onto my breast over the shirt. Smearing the black cloth with a heavy dollop of precum. Luckily in his slightly apathetic state I was able to stop him by standing up away from his penis, ripping my shirt off so he could have better access to my body. I also grabbed some of his weird lotion he had been using before to masturbate and spread it around my tits. Soaping them up nicely for him to freely thrust into his favourite cleavage.

I lied down flat on his bed and Kazuma quickly mounted me with his heavy cock lying between my breasts. His dick somehow looked even angrier now. Maybe it was because my request 'refilled his balls' so he was extra full of juice right now. A large amount of precum budding through his tip to drip onto my skin. I reached down and cupped his balls to feel the difference from before. At least I made sure it wouldn't hurt him in the long run. Now he can just keep using me and using me as much as he wants.

He took a handful of each breast and clapped them onto his cock. Spreading the soap around a little before he started to thrust in earnest.

Kazuma's cock was so hot. My tits had never felt so warm with his rod between them, their large mass jiggling around with his thrusts. I squirmed under him as his rhythmic thrusts spread the warmth around my body, which was now feeling a nice frustration as I couldn't reach down and play with myself. The soapy residue I put on left the perfect surface for his attacks, smoothly thrusting back and forth on top of me. Even with my few extra inches of height on him and my larger than average breasts his cock still managed to poke through the top.

I just laid there to let him have as much fun as he wanted. Occasionally kissing his tip when it got close to my lips, getting to taste that lovely salty nectar he was leaking out. Kazuma didn't seem to mind the extra attention, but then he didn't really seem to care either way...

"W-well? Do my breasts feel pretty good?"

"Not bad at all."

"Do you want to… fiddle with my nipples a bit?"

"Not right now."

I pouted at that a little, feeling disheartened at his attitude. Sure he was using me, and that was great, but like the sock I guess my breasts were just there to him. Just an unimportant tool. Even as he thrusts himself into my massive hills I could see him thinking about something else as he worked towards his climax, eyes unfocused and looking out to the horizon.

There should be a way for him to engage with me more. To want this as much as I do. I slipped my finger into his mouth and touched his tongue.

"W-well? How does it taste?"

He nodded, "You taste pretty great Darkness."

"Does it make you… wanna taste me more?" I ask, trying to bite my lip seductively at him.

"Why would I do that? I'm jerking off right now."

"R-right…"

Why did that hurt so much? Luna was all over me when she got to taste me... I had to remind myself again, this wasn't me and Kazuma having intimate sex. Kazuma was here to jerk off with my tits then get out.

He was using me. He was using my body for his desires. I was his cumrag. This is what I wanted, right?

I resigned myself to this fate and just helped where I could. The heat in my body hadn't dissipated and I could still have fun here from seeing Kazuma's cock enter and exit my cleavage. I was also enjoying Kazuma's vague grunts and moans while he enjoyed me. Though when Wiz's name escaped his lips it did depress me again.

My ruminations were cut off by my face being doused in his cum.

I tried to catch as much of it in my mouth as I could, a large portion still streaking over my cheeks and nose but with the huge load he let out there was still plenty I managed to catch. I hadn't had a chance to properly taste his stuff before since he had shot it down my throat. It was salty, somewhat sour, and delicious. The smell his cock had emanated before paled in comparison to the full on salty surprise that was now on my tongue and pumped all over my face.

It was all too much for my mind. A small climax hitting me from the sheer perverseness of me drowning in Kazuma's seed on my face.

As I was finishing scooping off the massive amounts of semen from my face to eat, Kazuma wiped his cock off on my breasts, finishing the transaction of 'using them to masturbate'. He then wiped his brow and lent against the wall. "Phew. Megumin's gone for half a day and I've already jerked off twice. Better let the little guy rest."

A pang of annoyance from her name stabbed my heart. He barely even cared that it was me he was using to jerk off! I know that's how this curse worked, but the rudeness didn't hurt any less.

"I want you to get hard again." His deflating dick stopped in its tracks to spring back up to full mast, earning another groan from Kazuma. "Time to take this to the next level. Your next masturbation tool shall be… m-m-my pussy."

"Can do."

I stripped down to my nothingness, giving Kazuma a sexy wiggle as I brought my panties down that he did not care for. He was just waiting patiently as his dick twitched around in front of him. Thankfully, even with the normalities he wasn't being impatient, maybe because this was his third time jerking off tonight?

I lay back down onto his bed. Accepting my position to be used and spreading my legs invitingly as he mounted himself up onto me again. My heartrate picked up immensely, the gravity of the situation setting in. Sex with Kazuma. Sex. With Kazuma!

But as reality quickly became apparent, so did the guilt. Sure I'd done a lot with Kazuma because of the earrings, but while a blowjob and titfuck were fun… losing our virginities like this… it felt different. He was probably saving that intimate part of his life for, well, her. I'd avoided thinking about Megumin too hard for a while now, but... she was still my friend. It wasn't her fault Kazuma chose her, she just fell in love with him too. Could I really do this to her?

My hand blocked his tip from entering me. "Kazuma… "

His dick twitched in annoyance. "Kazuma here."

"Would you be doing this… if it wasn't normal?"

"I really don't understand."

A sigh escaped my lips. My hand reaching down and stroking his penis. Just holding it made my pussy quiver in desire.

"I really want your dick inside me. To graduate me into adulthood… but I don't think I can go through with it. Even with everything that's happened, betraying Megumin like this is too much."

"Me and Megumin broke up."

…

....

"W-What?"

He sat back on his heels. Eyes looking a little sadder.

"Yeah, happened a couple months back. That's partly the reason she's off with her parents right now. We're giving each other some space." Kazuma said while scratching his arm. "It was mutual really. We just started growing apart these last few months. Arguing and getting on each other's nerves. Things weren't clicking anymore, and not in the 'we're out of the honeymoon phase' kind of way, sort of 'is this even fun anymore' kind of stuff."

"W-why didn't you say anything? You guys still seem so close."

He shrugged. "I think both of us kind of hoped it was going to work. We said we'll go back to being friends and see how our feelings develop, but it didn't work. And now that she's gone off I think it's officially time to call it quits."

They broke up?! All these months of avoiding them and they weren't even together?!

"But... you could have come to me? I thought you knew I had feelings for you..."

"It felt like you were avoiding me. I wasn't sure if you were still interested in me or if you were mad at me for picking Megumin over you."

My face was picking up redness. I really had to gather my courage now. "Are you interested in me then?"

He scratched his face awkwardly. "I'm not... not interested in you? I wasn't really expecting this question mid wank."

"Kazuma, do you want to… not masturbate right now?"

He sighed. "I guess. This thing is going to make sleeping awkward though."

"...would you want to have sex instead?"

"Absolutely."

I couldn't stop my huge excited grin spreading over my face. I grabbed his shirt and threw him onto the bed, switching positions with him and lining myself up to treat him to a full ride from a noblewoman. This was it. I wasn't about to trick Kazuma into having sex, or use these new powers to change how he felt about me. We were going to lose our virginities together because we both wanted to.

We both stared at it for a few seconds. My dripping pussy leaking onto his precum covered cock, both liquids mixing and making his phallus shine in the light.

"S-so, this is it? Are you sure, Darkness?" He suddenly faltered. "I- you… isn't this…?"

I just smiled at his awkwardness. Now that Megumin was gone I wasn't going to let anything stand in the way of us. "Kazuma. You know how I feel about you. It doesn't matter if you don't feel the same way about me… y-yet. But I just-!" My body squirmed in frustration. It was struggling to move the blood to my brain so I could speak. "Just… let me do this for you. Even if it's just for tonight. Even if you never want to speak to me again afterwards. I want this. You and me. Please." I begged, reaching down and using my hand to spread my moist pussy lips. "Please." I breathlessly begged again.

Kazuma gulped and nodded. I moved to line his tip at my entrance again, my excitement reaching dangerous levels as I felt his tip rub up against me.

With one last deep breath. I plunged his cock inside me.

I gasped out "Kazuma!" with his huge dick plunging deeper and deeper inside of me. I could barely think, just plunging myself further down and letting his massive dick fill me in places that had never been filled before.

I couldn't believe how good this felt, a lewd expression spreading through my face... but when I looked down to see how my partner was a pang of worry spread through me.

"H-how is it?"

He shrugged and my heart sank.

"Eh, pretty normal."

...

...oh.

Oh god no.
