"Heya Kokoro~! Wanna see something impressive~?"
Stopping, I turned and looked towards the guest room inside our main house, where I was greeted with the sight of Tsunade smirking at me as she peeked out from behind the door, the blonde haired Princess waving me over and making me frown slightly, though...
"Come in, come in! Take a look! I promise you'll like what you see..."
Frowning, I looked around at the empty halls and shrugged before heading inside, already feeling the familiar tingling from below whenever the busty Princess roped me into having sex with her, which was becoming increasingly often; I couldn't tell if she was naturally this horny all the time, or if being in a stable, reformed living situation allowed her to open her heart some more and let her spread her legs whenever she wanted...
After all, the amount of times I caught Anko and her fucking in the closets or in whatever room was free was astronomical at this point, and I had even caught Cameia with her a few times as well, my silent wife pinning the busty Senju beneath her and flooding her womb with seed.
Kurenai was the only one amongst us who wasn't readily seeking out sex from anyone, but that didn't mean she was free from lust either; far from it, since it took Anko and I a small push to get the red eyed beauty wet and ready for some fun, and she made it clear she was perfectly fine having us seek her out since it suited her wants even more, and I had also caught her with Tsunade a few times as well...
All in all, it would seem Tsunade was trying to become the ultimate homewrecker by having sex with all of us in hidden areas, but considering we had spoken about this quite often, it wasn't cheating, just... something that we were accepting of.
So when I walked into that room and noticed instantly that she was entirely naked, I wasn't too surprised, but the thing that did surprise me was what resided on her crotch, something that wasn't normally there at all.
"Impressive, right? Like it? I finally managed to get one that actually works... kinda."
Flicking around a meaty rod that was a tad thick and a bit short for that girth, but even then... it looked like it'd feel pretty good, but as I stared at it, I noticed a distinct lack of testicles, which Tsunade explained when she saw my gaze drop even more.
"Yeah, it's just the penis, but I can still ejaculate just fine. Problem is the sperm is infertile, which is something I need to keep working on, but otherwise... I have a penis now, and that means I can enjoy the same pleasures as Anko, Kurenai and Cameia~! Wanna try it out with me~?"
"Have you not used it yet..?"
She snorted and shook her head, her hand already stroking her thick shaft as she replied "Of course I used it! If you hadn't noticed, Shizune and I have a thing going on... something of her own demand, when she learned that I was trying to grow this. She uh... was of a big help the entire time, and is... demanding that I reward her efforts when I get this working properly..."
Plopping onto the bed, Tsunade moaned softly as she started to grope one of her large tits while still jerking off, making me salivate slightly as I took in the titillating scene in front of me before I just shrugged and peeled off my clothes, making Tsunade moan some more as her hand sped up.
Watching as I knelt in front of her, she smirked down at me before moaning harder as I brushed her hand away and wrapped my lips around her thick shaft, swallowing her cock to the root and making the older woman moan "By the Sage..! THIS is what Anko was feeling the entire time?!"
Seeing her begin to aggressively pinch and tug at her nipples while I sucked her cock and played with her pussy was amusing, and I could feel my own lust growing by the second as I got further into the mood.
"Oh! OH! C-Cumming~!"
I blinked in surprise before a deluge of sticky, thick cum flooded my mouth, the suddenness of her ejaculation forcing me to swallow it all down lest I choke on it... though that felt impossible since she was lodged inside my throat and spreading it apart.
Semen trickled down my lips while her pussy squirted on my chest, slicking my body with fluids and heating me up further, all while she drowned in bliss, pumping her sperm into my mouth without pause.
When she finally stopped and her cock was resting on my cheek, I raised a brow at her and made the blonde blush as she muttered "Still... getting used to it... sorry... that was... really good though..."
"Surely you aren't that quick with sex, right..?"
Her blush deepened, though she tried to save herself by saying "Not that quick, but I also have a lot of stamina! Promise! I might cum well before the others, but I can keep it hard longer!"
"You sound like a youngster, Tsunade... those are the same~ things I heard way back when, y'know? Well, at least I know it's something that can be 'trained' into you, so... how do you want me?"
She remained red, but this time with lust as she licked her lips and pat the bed beside her, the Princess saying "Y'know, people always talk about my tits, and it makes me happy, but... having this thing made me realize... ass is so much more important, isn't it..? So... Kokoro, can we do it doggystyle?"
I just chuckled and crawled onto the bed beside her, doing as she asked as I laid flat on my chest and lifted my butt, making her gulp as she kneeled behind me and caressed my cheeks, before she slid inside and moaned loudly.
I did as well when her thick shaft spread me apart - not as thick as Cameia, but certainly a tad larger than Anko was, while her flared tip scraped out my pussy as she started pounding me as hard as she could, the Princess moaning and gasping with each thrust as she took me roughly.
"O-Oh~! OH~! This ass..! You're so tight too!"
Pounding my cheeks, Tsunade spasmed as she breached my womb and started spurting her thick, jelly like cum inside me not even ten thrusts in, something that made me raise a brow before moaning alongside her as she started fucking me once more, her ejaculation not even fully over yet.
Like that, the Senju filled me with cum and made me feel pregnant again as she and I enjoyed one another's company for a few hours, indulging in the fruits of her research whilst everyone else had a relaxing day.
