Demon Slayer: Gag Smut

The midnight horniness had overcame him. Zenitsu crouched over Nezuko's asleep body. He looked over to Tanjiro, who was also in deep slumber, as the moonlight shone through the window and shed just enough light for Zenitsu to do his work. He slowly bent his back and lowered his head to Nezuko's face and felt his nose brush against her hair. He could feel tightness in his pants as he lightly sniffed Nezuko's hair on the side of her head to be greeted by the smell of peaches, and after this, his further curiosity lead him to slowly take off her bamboo muzzle, revealing her sharp canine teeth partly covered by her soft lips, in which he lay his lips on, slowly lowering his head and closing his eyes, enjoying the texture of skin that had likely never been touched by another man.

Zenitsu challenged himself further as he slowly ran his hand down Nezuko's chest and under her kimono, lightly touching her nipples and feeling every bump and ridge, but Zenitsu saw that this was too far when Nezuko's body twitched and he felt his body freeze with fear. Immediately, Nezuko grabbed Zenitsu mouth, muting him, and stared into his eyes before she flipped her body and top of his, pinning him to the ground, her sharp claw-like nails tearing his sleeves and digging into his arm. Zenitsu looked into Nezuko's rage filled eyes, and almost had a second to breath before suddenly feeling something being shoved into his mouth and him not being able to speak despite Nezuko's hand no longer covering his face. Nezuko then turns him over on the ground, Zenitsu's chin being forced into the wood floor and feeling drool run from his muzzled mouth. Zenitsu felt his arms being held down behind him then tightly knotted by what seemed to be cloth, before feeling his belt being unlatched and his pants slipping off of him followed by his underwear coming off.

Zenitsu jumps and makes a muffled groaning sound as he feels Nezuko's sharp nails run down the skin of one side of his ass, before the pain subsided into a burning pleasure throughout the lower half of his body. Nezuko scratched him again but on the other side and then again and again, Zenitsu groaning each time and even letting a tear run down his cheek.

Nezuko bent down to Zenitsu's level and licked the round surface, picking up the blood on her tongue and mixing it with her own saliva. She spits on Zenitsu's butthole and watches the red saliva run down his taint before embracing it with her lips, circling her tongue around the outside and dipping further inside.

Zenitsu felt Nezuko's long wet tongue inside of him, massaging the corners and poking deep inside and his leg muscles constricted in pleasure and he felt his penis twitch and ache as saliva ran down his scrotum.

Nezuko grabbed Zenitsu's balls, her sharp nails poking them, then she grabbed Zenitsu's penis and forced it into her lips, sucking and moving her head back to forth on Zenitsu's shaft.

Zenitsu could feel the edges of Nezuko's sharp teeth almost cut the skin of his penis as she sucked the life out of him, until Zenitsu couldn't take it anymore and he felt a deep pleasure in his balls as white liquid burst into Nezuko's mouth.

Nezuko felt the stick liquid thrust in all direction in her mouth, onto her tongue, the inside of her cheek, and even at the back of her throat. She let Zenitsu's penis fall out of her mouth and she licked the cum inside of her mouth and swallowed, making a gulp sound.

Zenitsu stared blankly at the floor in front of him in a trance with drool running down his chin and an aching pleasure through his ass, taint, and penis.

Nezuko hugged Zenitsu and pulled him onto the floor with her as he stared into space, still recovering from intense pleasure. Nezuko smiled and kissed Zenitsu on the cheek before whispering in his ear, "Thanks for the meal, Zenitsu." She closed her eyes and snuggled her head on Zenitsu's neck. The sun shone through the window and into Tanjiro's eyes. He turned his body around and yawned before stretching his arms and sitting up and looking to the side to see, Nezuko in a dark corner on top of Zenitsu. He felt an uneasy feeling in his chest as he focused his eyes to see Nezuko's red stained lips and Zenitsu with the muzzle.

Did Nezuko murder Zenitsu? Tanjiro thought as his heart started to beat rapidly and his breathing turned into a quiet whimper.

Tanjiro sat paralyzed until he saw Zenitsu slowly blink and open his eyes, and as he tried to move Nezuko tightened her grip around him and open her eyes.

"N-Nezuko?..." Tanjiro asked with wide eyes and a gaping mouth, staring deep into Nezuko's eyes, trying to piece together what was happening.

"It's ok, I found a different source of energy." Nezuko said softly.

Tanjiro looked at Nezuko's hand as she slowly guided it down Zenitsu's chest, and to his pants and massaged Zenitsu's penis. Zenitsu flinched awake and looked at Tanjiro nervously, the muzzle still in his mouth and blocking his speech.
