Obsession Aizen x Reader

Mayuri's Lab II

"Is that my- penis?"
Aizen looked at it and then back to you.

"Uh-um no?" Your eyes dart around the room
He let out a short chuckle. "I can sense my reiatsu on it" he picked it up. "I did let Captain Kurotsuchi take a measurement of it but- I didn't know it was finished. Looks like it's being used for what it was made for?" He shot you a glance.

"I haven't used it-" you were slowly dying of embarrassment.
Aizen shut the door behind him relinquishing the light from the room. You could barely see him but you could feel him getting closer.

"(YN)" he called for you, his voice was low but still held authority you had no choice but to answer. "Yes" taking a step forward to meet him.
"Yes, what?"
"Yes Captain Aizen"
"Good" he towered over you, his praise making you weak knead. His hand finds its way to your waist.

"I don't want you dropping to your knees just yet"

'How did he know?-'

"This" he holds the dildo up, the tip rubbing against your throat. "Only gives you a fraction of what you would get from the real thing"
He lines the tip up to your lips "tell me, do you want this or what I can give you?"
You open your mouth willingly, making him crack a smile.

"Stick your tongue out" his voice more aggressive. He slides the toy in "Tell me (YN)"
"I want- you-" taking the toy further in your mouth

"Right answer" he played with your throat, slowly watching the toy slide in and out. He stops for a second and disregards the toy to the floor before leaning into your ear. "Get on your knees" the corner of his eye catching yours.
Aizen steps back taking his support with him.

You drop to the floor and look up at him the bulge in his pants almost obstructing the view.

Aizen unties the bottom of his shihakusho His dick heavy and hanging over you. He let it rest on your face and you had no problems with that.

It was warm, hot and ready to be sucked

Immediately you took it in gagging and spitting. "Fuck...(YN)" he gripped the back of your head pushing you further in but not thrusting.
"You're better than I expected- I always thought you were shy ahh- but look at you" he pulled himself out tilting your head so your eyes met.
"Sucking on my cock like you would die without it" he let go of you letting you get back to work.

You took it slow humming his name and each moan sent him a ripple of pleasure. "Yes..I can feel it, keep fucking going!" he began pumping into your mouth

Your hand gripped the sides of the Captain's cloak.
"Good- uh ah~ your throat is so tight" Aizen watched as the outline of his cock could be seen each time he thrust inwards. The sight almost made him cum.

A knock at your door slowed his pace down a bit.

"(YN), have you seen Captain Aizen? He hasn't returned to his quarters"

You could tell it was Momo. You tensed for a bit a side of you not wanting her to open that door. And the other wanting her to see you with Aizen's cock down your trait almost like a prize you got over every other female lieutenant.

"I can feel you tense, are you nervous about her entering?" He smiled holding your chin up but still relishing the wetness of your mouth.

"Let's find out?" He looked over at the door.

Momo knocked again "(YN)?...(YN)?!"
Aizen reached down slipping his hand into your shihakusho he felt the warmness of your breast, and he massaged them slowly and ever so slightly running his hand over your hard nipple. This caused you to moan out.

"(YN)? So you are in there?! are you trying to avoid me?" Momo shift the door open slightly

"Fuck" Aizen moaned feeling your throat tense even more. "I'm gonna cum"

Momo slide the door open further that was definitely Captain Aizen's voice she heard. But why would he be in here with you?

"Captain Aizen?!" She watched as he pumped his cock over your face. She noticed you on your knees on the receiving end. She knew she should run away but her eyes were fixed on the sight before her.

He tilts his head back realising his seed onto your face. Momo runs out crying. 

"She'll get over it" he huffed coming down from his high.

"Same time tomorrow this time we will use the bed"
