"Why do I have to follow you around Old Hag?" I complained.
"Because you are a young girl who shouldn't be trusted with Jiraiya." Tsunade sighed "Besides I have my own training to do with you?"
"Why should I train with you?" I grumbled "You stole my title, I was gonna be the first female Hokage."
"Too bad, so sad." She smirked.
"Stupid hag!" I yelled "Well at least I still have my other dream."
"Hmm?"
"I'm gonna be the sexiest Hokage ever." I said striking a pose.
"You really think you're gonna be sexier than me?" Tsunade teased "A scrawny, flat runt like you?"
"Hey I'm still growing!" I pouted "And besides when I do become sexy I'm gonna be way less saggy then you are."
"That's it you brat!" Tsunade grabbed my hair and started giving me a knuckle sandwich "Keep talking smack and you'll regret it!"
As she grinded her fist into my skull my head was right by her big boobs, they were swinging around and slapping against my face.
If I'm gonna lose the title of first female Hokage to someone… I guess Tsunade is attractive enough for me to concede; besides… She's super sexy.
"So what is all this training you've been talking about?" I asked, following the older woman around.
"It's about what makes you… you." She shrugged.
"What makes me, me?" I asked.
"You're… manhood." She said "Obviously you know you're not exactly like the other girls your age, but you're also at that age where your body starts changing, you may feel more attracted to others… alright you know this is freaking dumb, look you've hit puberty, practice safe sex, clean yourself regularly and don't be stupid."
"So basically they want you to give me 'The Talk'?" I asked.
"Yeah… look, just be a good girl, wear all your girly stuff, put a bra on, don't walk around naked and you're gonna be hopped up on hormones so try not to screw everything that moves."
"Hmm? What did you say?" I asked as I stopped looking at her huge hooters.
"This is exactly what I'm talking about." She groaned "Come with me and I'll take care of your… problem."
I followed Tsunade all the way to her office, once inside she locked the door and stared at me.
"Since there's no one else around I suppose I'll have to teach you how to be a real woman." She said pulling her top open and letting her big breasts flop out "Let's start."
"W-W-What?" I gulped as I already felt you know what stirring.
"I can't just let you wander around the village without making sure you won't be a total pervert." She said "I have to test you and make sure you can be… a real woman."
She suddenly dropped to her knees and started pulling my pants down.
"My it's larger than I would have anticipated." She said, inspecting my penis.
She suddenly slapped her tits around it and I moaned as she began shaking them. I had never felt anything like this, so soft yet so warm. Sometimes when my dick would peek out the top of her deep cleavage, Tsunade would give it a quick lick, making me gasp with pleasure.
"I've gotta make sure you can do all this right." She quickly snuck in a flick of her tongue "I hope you can last long because I've got lots to train and show you."
"I can… UGH!" I groaned "Take it!"
"Good." She smirked, hefting her tits up and down.
I kept leaning back and moaning as Tsunade stimulated me. She was really getting into it the way she was moving her chest and tongue.
Someday… I'm gonna be even hotter than she is. I'm gonna have a rack just like that, and since I already have a penis would that make me doubly hot?
"OHH!" I suddenly felt pressure building up down below and knew what was about to happen "I… I… I'm cumming!"
I moaned as I shot ropes of cum all over Tsunade's chest and even a couple on her face.
"Not bad, you lasted surprisingly long." She said, cleaning herself off before laying back and spreading her legs "But let's see how long you last with the real thing."
I practically jumped into her, getting my penis inside her while my head crashed onto her pillow like a bosom.
"So soft." I moaned as I nuzzled into her and got used to being inside of her.
"Marvel all you want but don't just lay there," she laughed, "Do something."
"Oh right." I said slowly moving my body and making my hips move, causing my cock to slip in and out of her.
Tsunade groaned as I first got settled into a rhythm, while I plowed into her I also used my tongue and lips to lick and suck all over her big chest. Tsunade was moaning and encouraging me to keep playing with her, as I ravaged her bust she would sometimes reach back and slap my little butt or wrap her legs around me and force me deeper into her pussy.
"UGH!" I grunted "Feels so good…"
"That's it, keep a rhythm, don't stop till the lady is satisfied." She moaned.
"OH… UGH!" I growled moving my hips faster and faster.
The two of us grinded into each other for a while, my young body hugged my Tsunade's mature frame. I was going to cum, I wanted to cum, but Tsunade said not to finish before her and she didn't seem to be breaking anytime soon, if anything she was only just getting started.
"I… can't do it!" I moaned as I sprayed cum inside her walls.
"Fufufu…" she laughed "You lasted far longer than I expected, good job… but you still have a ways to go."
After that Tsunade took me back to her house and made me have sex with her for what seemed like hours, the entire time she encouraged me and it seemed like I was lasting longer and longer. When I was too tired to keep going, Tsunade hugged me as I fell asleep.
"You're wonderful Naruko, someday… you'll be a beautiful woman."
***
The next day...
"Alright, are you ready Naruko? It's time for your second lesson." Tsunade instructed.
"Bring it on!" I cheered.
"Okay here's today's trial." Tsunade said "You're going to drink this, it's got drugs in it that will force you to get an erection but will make you unable to climax, Shizune and I are going to play around with your body. This exercise will help train your body to endure more rigorous sex acts."
"Okay?" I said apprehensively "If you say so."
I took the little flask Tsunade gave me and drank it, instantly my body felt warm all over and my penis was rock hard.
"OHHH!" I moaned as I felt the need for pleasure fill my mind.
"Ready Shizune?" Tsunade asked, pulling her tits out.
"Yes Ma'am." Shizune smiled, stripping down. "I'll help put her through the grinder."
"Yes, we certainly will grind on her." Tsunade smirked.
"HAAA!" I gasped as the two started to rub their bodies against me.
My skin is so sensitive, every part of me feels like I'll cum just from a gentle touch.
"MMMM!" Tsunade rubbed her breasts against my back.
"Haa~" Shizune moaned in my ear as she rubbed my thighs. "I can't wait to see how far you can go."
As Tsunade stood behind me and rubbed her hands over my chest and stomach Shizune leaned over and lined her soft butt up with my girth, she slowly pushed back and forced me to enter her.
"HAAAAAA!" I screamed in absolute pleasure.
"Oh it's big." Shizune moaned as she started pumping her body and sliding on me.
"She is, isn't she?" Tsunade said, pressing her hard nipples into my back. "She's such a good girl, how much do you want to cum already, I bet you're dreaming of filling Shizune to the brim with your hot, sticky jizz."
"Fuck me, fuck me Naruko." Shizune begged, backing her ass up faster and faster, her cheeks shaking and slapping together.
I managed to finally move my hands and grab Shizune's ass. I dug my fingers in and started thrusting so that, not only was she backing into me, I was now ramming forward into her. Our bodies collided in a sexual musical. As I kept fucking Shizune Tsunade walked around and started kissing her assistant.
Once they were done making Shizune leaned down to play with Tsunade's breasts, she was slapping them around and licking the nipples and I kept ramming her. My body was screaming for an orgasm but the drug was making it impossible.
"Yes… yes… AHHHH!" Shizune moaned and got even tighter.
She just came… I need to cum!
"My turn." Tsunade said, pulling Shizune off and inserting me into her pussy.
Unable to control myself I started pounding her. Shizune walked around and started playing with my flat chest, tickling my nipples with her tongue.
"You're so cute Naruko." She whispered "I just can't get enough of this tight little body of yours."
"Not every part of her is little." Tsunade said as her fat tits swung around "Something is certainly bigger than average."
"So you hear those breasts shaking?" Shizune asked, teasing my body. "Tsunade is just so attractive isn't she. I hear you want to be even more beautiful than her… I wonder how big your chest will get, how round your butt will be… how huge your cock will become."
"Please… just let me cum." I begged.
"Not yet." Shizune got on the floor behind me.
"GAAAAA!" I moaned as she spread my cheeks and started licking at my vagina.
"How does she taste?" Tsunade asked as I my dick in and out of her.
"Delicious." Shizune licked her lips before going back to my pussy "Sweet like honey."
"I can't… not from both sides." I begged "Please!"
"Just a little longer and you'll pass." Tsunade said. "Now pound my pussy."
I dug my fingers in harder and started slamming my teacher more and more. Shizune probed her tongue deeper into me, at this rate I would pass out from pleasure overload before I actually got a release.
"I think she's had enough." Tsunade said "I'm about to break myself, give her the antidote so she can cum with me."
"Yes Ma'am." Shizune said, licking her lips of my juices before drinking something.
"MHMMMM!" she suddenly kissed me and forced something into my mouth.
I felt Shizune's tongue exploring my mouth as I swallowed some pill. In an instant I felt my body snap and I moaned into my kiss with Shizune, my cock spasmed and started flooding Tsunade's warm insides with cum.
"That was a big one." Tsunade said, pulling off me, my cum leaking out of her.
"Not only is she good for the rough part, Naruko is a great kisser too." Shizune complimented.
"Ha… ha…" I fell back "So… intense… can't… move."
"Yeah you'll be out for a few hours." Tsunade smiled. "Sleep well."
