Hard Training—Shizune
"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."
