Killua x female reader: Assassin's Bride

Extra chapter LEMON 4

Anal always requires consent, so don't copy what I did here, and yes, there needs to be time to prep that butt before you do anal. Anal will hurt if you don't prep, so no need to rush.

Killua was out, and I was at home. I played a few rounds of games to pass the time and even cleaned the house. When I was cleaning, I found the adult toys and lube that I bought on our honeymoon. I laughed for a bit, then had a sudden idea.

I went out and bought a strap-on, beads, and a butt plug. Upon returning, I was greeted by an unhappy cat, waiting at home. He interrogated me where I went. I gave a simple answer, knowing that he most likely knew where I went and bought anyway.

"A little something to spice up our night." I smirked. I knew he wouldn't be able to say no if I begged him nicely.

"Oh?" One of his eyebrows raised.

"You'll have to wait," I lick my lips, my eyes curved into a crescent moon, "or do you perhaps want it now?"

He blush and turns away, turning on the television, not answering me. I knew it. He knew what I bought and is just embarrassed to say it aloud. I went to put it in our room, excitedly waiting for the night to arrive.

Once the night arrived, I was impatient. First, I was going to have to please him. Then, I'll ask him, but if he says no, we can take it slow. Once we got onto the bed, I gave him a fellatio(blowjob). He was a bit startled, but complied.

"Do you think we can try anal?" I ask him, swallowing down the cum.

"That's why you bought it?" He ask.

"Yeah. If possible, I really want to try it." I said.

"Sure then."

"You sure? You promise?"

He nods, and my eyes lit up. I immediately went and took out the beads and some lube before climbing onto the bed again.

"Then, could you please take off your pants completely and turn around?" I smiled.

"......." His eyes widen at the words, "I'm not doing it to you, but instead you're doing it to me?! No wonder you bought that strap-on even though you have mine!"

"Uh-huh. You promised, didn't you? I promise to go easy and slow." I answered.

His eyes looked down at the supply, then back at me. He hesitated before saying, "If it hurts and uncomfortable, we're stopping immediately."

"Thank you, Killua!" I hug him.

I waited for him to take off his pant. He sighed before doing what I had asked him. Once he had turned around and laid on the bed, I lifted his butt to the preferable height.

"Then tell me if it hurts." I said.

I open the lube, putting it on him. He flinched at the cold feeling, but didn't say anything. I was glad that I had cut my nails short beforehand. I slowly insert my finger into him. He was clenched up.

"Does it hurt?" I ask.

"..... No." He replied.

I push my finger in further. He was so tight. I look at his expression. He had buried his face into the pillow, not allowing me to see it, but his ears were red. I pull it out, and he let out a soft moan. I put more lube before inserting inside him again.

"Do you think you could insert your fingers whenever you can? It'll at least take 2 weeks to prep your butt." I said.

"Ha?!" He lifted his face off the pillow, "why 2 weeks?"
