(Genryujin's POV)
I raised an eyebrow, "Is that so?" I said
She handed me the jug, "Yes." She said, "Drink."
I took the jug and sighed, "Always with some bullshit....." I muttered, "Are you sure this won't have some serious aftereffects? I can't trust Mayuri sometimes."
"If there is, you can always purify yourself with your Zanpakuto's ability." Nemu said as she took a step back, "Please drink it."
I nodded, "Okay okay." I said as I lifted the jug and began to drink it
As the liquid hit the lips, I was hit by the pungent smell of cough syrup combined with grape and prune juice. As always, Mayuri knew to make his concoctions flavored when it came to me.
It didn't taste good, though. The bitterness was so much that I gagged as the liquid came down my throat. As I gulped it down, my entire body began to shake at how disgusting I found the damned thing. I still took it all in, gulping every drop of whatever the fuck this potion was supposed to do. Mayuri always had some elaborate explanation that he never bothered to fully explain to me. I did trust one thing about him; he'd never do anything to fuck me over.
"Ah...." I said wiping my mouth as I coughed a bit, "The fuck...."
I felt my body began to feel a bit cold, maybe it was the potion taking effect.
"Are you well?" Nemu said
"Y-yea...I guess." I said as I rubbed my forehead, "That was disgusting though.....I-"
I looked down to see my cock was already up and hard, it felt like it was going to rip through my pants. What's crazy is that I didn't feel it get erect, I just noticed the sensation of my tip stretching my pant out.
"T-The hell?" I said with a bit of suprise
"It is working as intended." Nemu said as she began to strip, "Very well, let us proceed as planned."
I watched as her bare body was exposed, her massive breasts plopping down and bouncing as she took her panties off. I noticed her pussy was slightly wet, maybe an aftereffect of whatever Mayuri injected her with.
She walked over to the tank that contained my Gigai and bent over, exposing her pussy as her fat ass was in full-display.
"Please begin, My Lord." She said as she blushed
"I...uh...." I started, "No foreplay? Just straight into it?"
"If you wish to get your Gigai as soon as possible, then I suppose so." She said
I sighed and nodded, "Okay...." I said, "How long is this supposed to last? The aphrodisiac that is."
"An hour." She responded, "So for an hour, you must fuck me as hard and good as you possibly can. It is the only way."
I frowned, "An hour?" I said, "Damn...."
I took my pants off as I walked over to her, her pussy beginning to leak a bit.
"What a beautiful sight, your exposed cock...." Nemu said softly
I took my shirt off as I gently grabbed her by the waist, pressing my cock against her fat and meaty ass. It was a great sight as well, her amazing body. Her ass was so nice and round that I almost forgot she was related to that bastard.
"Hm..." I said as I gently groped her ass
"Mm~" She said, "Forgive me, Lord Genryujin....I am a bit sensitive due to the serum, but please continue.....do not mind my moaning...."
I looked at her, "Your skin is soft..." I said as I ran my hand up towards her chest, "And these....are really nice...."
I grabbed a handful of her breasts, groping them as I pressed myself against her.
"Ah~" She moaned, "Yes~"
Her breasts were so big and soft, the arousal was so great that my cock was beginning to twitch already. It was urging to be inside her pussy so badly that it concerned me.
"Sorry, Nemu...." I said, "I...have to put it in already..."
"I understand...." She whispered
I leaned back and slapped her ass, rubbing my cock against her drenching wet pussy. I had a feeling that her hole was tired of waiting and wanted my rod inside it.
"These thoughts...." I thought to myself, "This massive urge....is it me or the drug?"
I shook my head and gently inserted the tip of my cock into her pussy, feeling it suck me in completely as I groped her ass.
"Ahhhh~~!!" Nemu moaned, "Y-Yes~!"
Almost as if I was entranced, I rammed my cock all the way inside, colliding my pelvis against her ass, making her fat cheeks clap loudly. I think this was part of the drug's effect, I don't always do this unless the pussy is that good. And that feat belongs to my beloved Retsu whenever I haven't had her after a long time.
"Oh...." I said as I looked up, "Shit...."
Her pussy was so wet and warm inside, her walls wrapping around my fully erect and hard cock as the tip was squished against her womb. It was such a surreal feeling, my head was spinning at how good it felt. This was definitely an effect of the stupid drug and I was trying my best not to bust a fucking load and keep my mind clear.
"Ahh~" Nemu moaned, "Please...continue~"
I looked down and saw that she was looking at me while blushing, "O-Okay..." I said as I slowly began to move my hips, "Nemu....."
As I began to fuck her, I felt my cock rub against the wrinkles of her walls, the arousal and bliss I felt was sending chills to my body, making me lightheaded by the slow and gentle thrusts.
"Ohh~!" Nemu moaned, "Yes, that's it~"
I then began to pick up the pace, thrusting my cock into her pussy a bit faster as I looked down at her cheeks rippling, adding more to the arousal. A massive chill began to creep up my spine, making my entire body tremble. This was a foreign feeling; chemically-induced arousal. All of my lust was natural and this was adding more to it.
This was going to be bad.
"Fuck." I said, "Nemu...."
"Sorry, I won't be able to control myself."
