A new discovery

Tanjiro had gone to collect materials for a basket to put Nezuko inside of, so it was just me and her alone she was currently facing away and lying down, I didn’t pay much mind to it and started to think about all that’s happened to me. Suddenly, I heard something strange… almost like humming or… grunting? It was coming from Nezuko so I crept behind her and… she was masturbating?! I suppose it makes sense considering that she can’t have had many opportunities for self pleasure recently, she must’ve thought I either wouldn’t notice or was too backed up to care. I kept watching as she played with her clit and even stuck a few fingers inside of herself, she started going faster and faster, the noises she was making got a bit louder and right when she was about to tip over the edge… I grabbed both of her hands, forcing her to stop. “I had no idea you were that much of a slut, Nezuko” The panic in her eyes from being caught and the arousal from being brought to the edge was replaced by fury at my words, but before she could do anything too drastic I took a gamble… “I wonder what your brother would think if I told him his sister was that much of a slut” Perfect, the panic had come back “Don’t worry Slut, I won’t tell… unless you give me a good reason to that is…” she glared at me and grunted which I assumed was a question asking me what I wanted “You see, watching your slutty little performance has made me quite hard, deal with that and I won’t tell Tanjiro what a raving slut his sister is” I smiled as she hesitated “It’s my word against yours Nezuko, or lack thereof” I laughed at my little joke and continued speaking “In fact, now that I think about it I could embellish the truth all I want… as long as I don’t say anything you can disprove without speaking, I wonder how much disgust he’ll look at you with when I tell him” Nezuko looked fearful once again “Of course… it’ll be our little secret so long as you deal with my erection” I stepped close and whisper in her ear “So, what’ll it be? Do you want your brother to know how much of a slut you are? Or will you do one little thing for me? The clocks ticking and not even I’ll be able to help you if he finds you being your slutty self around the first man you see…” My continued whispers seemed to convince her and she began to undo my pants. Once my dick was free she wrapped her hand around it and began jerking it quickly, seemingly in a hurry.

Nezuko obviously wasn’t all that experienced with handling a cock but I wasn’t expecting her to be, considering how little contact she’s had with the rest of the world. After a few minutes of her trying to make me cum as quickly as possible while glaring hatefully at me I took another gamble, hoping I wasn’t about have my cock ripped off in her hands I told her teasingly “I wonder how long it’ll be until your brother comes back Slut” No response but she went a bit faster “At this pace he’ll find you out” Somehow her glare became filled with more anger “You know… as cute and helpless as you look right now, I’m sure I’d reach the edge a lot faster if you showed me your pretty little tits” I finally said, praying to God that I wasn’t about to die.

Luckily for me she seemed to actually consider it for a while and, using her free hand she undid her pink kimono above the waist and showed me her bare chest, with her nipples still hard with arousal from her previous denial she went even faster jerking my dick, obviously not wanting her brother to come back and see her in this state. Fortunately for her, the sight of Nezuko topless and giving me a handjob was too much to bare so I started to get quite close when I had a thought and a devious idea “You know Slut, Tanjiro has a great sense of smell. Now that I think about it he would probably be able to smell my cum after I orgasm” She started to slow down after hearing this “Don’t you dare slow down Slut, it’s okay I’ll figure something out. You don’t have to worry about anything other than my dick” I ruffled her hair patronisingly, but that look in her eyes… the anger was replaced by a small bit of desire followed by a flash of surprise at the way she felt after receiving my affections “That’s right just keep taking care of my cock, nothing else matters” I removed her bamboo gag and her thoughts returned to her as her mouth was freed “It’s okay Slut, I know of a way to stop Tanjiro from finding out how much of a slut you’ve been… all I have to do is finish in your mouth, and then your brother won’t be disgusted by you for the rest of your life” Nezuko almost stopped but thought better, I could just about read the emotions on her face. She was feeling very suggestible and horny and was having difficulty coming up with any better ways other than for me to cum in her mouth.

The clock was ticking and finally she accepted what I said and quickly sealed her lips over the head of my dick, accidentally pushing it up against her tongue causing her to taste my pre-cum, and after the stimulation from my head rubbing against her wet tongue became too much I finally orgasmed inside of her mouth, spilling it all over her tongue. After I started to cum Nezuko tried to recoil from the taste, but I held her on my cock and before she could overpower me I quickly told her “Remember Slut, if any of it spills, Tanjiro will find out how much you love slurping on dick” She got the message and stayed there as I finished, once I was sure no cum would leak out I pulled out of Nezuko’s mouth “Now swallow, Slut” She scrunched up her face but eventually did as I said “There’s a good Slut” I praised, while patting her head and again there was a flash of surprise on Nezuko’s face at how good my praise felt. Suddenly I had a very good idea to make her more submissive and malleable “See Slut? Didn’t that feel good? Now lie down” She followed my command wearily, wondering what I was going to do next. I observed the way she was panting from arousal and the needy look in her eye and decided to take another chance. I tied her bamboo muzzle back around her head and quickly moved my hand to her pussy, before she could react I whispered in her ear “It’s okay Slut… I see how **** you are for your own orgasm… let me take care of you Slut… I’ll make you feel really good” As I spoke she started to calm down and let me caress her needy little pussy. It looks like the chance I took was a success, she was so aroused from not being able to finish that she let me do whatever I wanted with her. I inserted my index finger into her sopping wet hole and started moving, earning a few grunts from her, after getting her used to my finger I added my middle finger and started moving again, causing her to let out a muffled moan, then I directed my attention to her clit which was pink, cute and erect, I started to play with it with my other hand causing her to let out a long moan which was cut off when I started going faster. I kept going faster and faster, adding my ring ringer inside of her tight pussy, she was heading to the verge of orgasm and right when she was on the edge… I stopped, completely pulling my fingers out of her and forcing her to ride the edge as I played with her hard nipples, her hips thrusted upwards begging for attention and after 20 seconds of her riding that torturous edge I let her nipples go and watched as she mewled with frustration, her brain so addled with pent-up arousal that she didn’t even realise her hands were completely free and could’ve finished herself off at any point. Once she had calmed down a bit I started playing with her again, rubbing her clit raw, stopping on the precipice of an orgasm and playing with her again, never letting her feel relief.

I continued edging her for thirty minutes straight until eventually I heard Tanjiro coming back, I stopped to admire my work for a few seconds before cleaning her up. Nezuko’s eyes were unfocused, her hair ruffled from her hands pulling at it with stress and helplessness, her cheeks stained with tears, her muzzle and chin soaked with her own drool, her face scarlet from her arousal, her clothes hanging off one of her arms and laid under her as her only protection from the cave floor, her nipples pointed upwards and hard as rocks, her breasts attempting to return to their natural colour after being squeezed until they had red marks all over them, her chest rising up and down while she panted with unsated need, her pussy overflowing with her own juices, her trembling clit turned red from **** and fully erect as if straining to escape, her thighs damp with arousal, her bare heels dirty from pushing against the floor as a result of her struggling. I quickly put her clothes back together and dried her face with my sleeve, I laid her against the cave wall and straightened her hair. She was still completely out of it so I closed her eyes to pass her off as sleeping. Once I finished, Tanjiro appeared at the entrance to the cave “Nezuko… hmm? Nezuko! Markus, where did Nezuko go?” Tanjiro asked worriedly, I gave him a calm look and responded “Nezuko fell asleep shortly after you left, she’s just behind me” I stepped to the side and pointed to Nezuko, Tanjiro looked relieved “Thanks for looking after her Markus, I don’t know what I would’ve done if something had happened while she was sleeping. I bought a basket and some straw to put Nezuko inside of so we can travel during the day, can you look after her for a little bit longer while I fix the basket?” I smiled at him and agreed, once he was gone I turned back to Nezuko to see her masturbating through her clothes absentmindedly she was getting pretty close so I decided to let her bring herself to one more edge, she didn’t realise I was watching and must’ve thought she would finally be able to bring herself the release she so desperately desired, I could see the hope on her face, her toes curling, her chest expanding getting ready to moan out one of the strongest orgasms of her life- and at that very moment I pinned her wrists to the cave wall, denying her once more. She struggled for a bit, trying desperately to reach her needy little pussy but she couldn’t escape my grasp and after kicking her legs despairingly she gave up, letting her orgasm elude her once more “Bad Slut” I scolded “I didn’t give you permission to touch yourself, maybe I should tell Tanjiro what a slut you’ve been…” That woke her up, she started whining pathetically and pleading with her eyes “Aww you’re such a cute little Slut, okay I won’t tell him… but you have to promise to be a good slut. Do you promise to be a good slut for me?” She nodded meekly in response “Good Slut” I patted her head again and it took her a few seconds to hide that look of ecstasy from me “Now pay attention Slut, your brother is making a basket for you to ride in so that you can travel during the day. You’re going to edge yourself into a trance as soon as we get moving, do you understand Slut?” Nezuko hesitantly nodded again “Good Slut, just remember that if you cum…” I pinched her nipples through her clothes “I’m going to tell Tanjiro everything you did, like how I caught you masturbating and then you sucked my dick and then continued masturbating until he came back” The look of fear in her eyes was so delicious.

Once Tanjiro was done with the basket he brought it into the cave and prompted Nezuko to crawl inside, once she did so he wrapped a blanket around the basket and put it on his back. We set off for Mount Sagiri shortly after, and I was entertained by my little sluts whimpers as she reached her first edge inside of a cramped space that was pitch black with nothing to focus on other than her dripping pussy…

This was going to be a fun walk
