"You're a sadist!"

"I know ya know." Shizuku sat on Naruto's right shoulder, holding onto his head as she forced him to run while carrying her. Not only was he carrying her, on his other shoulder he had Koneko riding him, also holding his head to stay on. There, there was Serafall latched onto his back, and tied around his waist he was dragging several tires (five of them in total) behind him. Considering he did so well with his push ups, she wanted to up the difficulty for his cardio/lower body work out as well. It wasn't willpower training if you didn't push your willpower to keep going to the extreme, well, at least it wasn't good enough for Naruto to do weak willpower training. "You're going to take each of us to somewhere we want to go ya know." Shizuku didn't give him a set amount of kilometers, she just gave him a goal.

Once he had taken all of them to the places they wanted to go, he would be done running... after he ran them back to his apartment. Once it was just her training Naruto, meaning Koneko and Serafall were gone, then she would give him a set distance. She would also add more tires to ensure that he was dragging a suffice amount weight behind him.

"This is good." Koneko was licking her popsicle, since that was what she wanted to go and get. She had purposely chosen a convenience store that was far away from Naruto's home, but that was just her revenge for Naruto calling her a Shrimpy Bitch earlier. She could use without the bumpy ride against her body, seeing as his shoulder was rubbing up against her mound. The small tingles of pleasure were nice, but... well... the feeling of sexual gratification actually made her revenge a little better all things considered. Revenge, a nice icy treat, and pleasure all wrapped in one.

A girl could get hooked on revenge, if it tasted so sweet.

-2 Hours Later (Back at the Apartment)-

"Careful not to drown."

Koneko stated as she watched TV with Serafall, Naruto's training was still going, seeing as Shizuku was testing the limits of Naruto's body. This time, it was just Shizuku, sitting on top of his face with her legs wrapped around his head. She was forcing him to do extra difficult sit ups now, and he was going to do them until he got to at least 1000 of them this time. Considering the girl was always dripping with water, and her panties were almost always soaked, Naruto drowning wasn't that far off of a legit concern. Even more so considering the girl was quite possibly using his face to pleasure herself, if her slightly colored cheeks meant anything. Not to mention, she was more than willing to use him as a tool for her masturbation when she healed him.

Serafall was half-asleep, laying across the couch with her head in Koneko's lap.

The place she had chosen to go was a candy store, and she had overloaded on sugar. For 30 minutes, she hadn't shut up even once, and after that she had experienced a hard crash, where she was just tired. Koneko didn't want to have her head on her lap, but considering who it was, she didn't have much choice in the matter.

"You can do it Naru-tan..." Serafall yawned again, and snuggled into Koneko's soft, plush lap. For a Rook with a lot of strength and durability, the softness of her body was almost unrivaled.

Shizuku didn't deny it either.

'It's a shame he's almost done... I was able to rub myself to climax using him close to 21 times...' Shizuku thought her words. 1000 sit ups was a lot of time to pleasure herself with his face. If she was going to train him, then she was going to personally benefit from it. The best part, seeing as she wasn't having sex with him, Naruto couldn't complain about her getting some mild pleasure from this. 'Even better... the Slutty Cat can't say anything against this either.' Shizuku was even more pleased that Koneko was being the perfect tool to keep Kuroka away.

No Kuroka bothering her, a very decent supply of pleasure, and she was training her future ally. Oh, and the training would make his body nice and hard, as well give him large boosts in stamina, something that she personally would still get benefits from when her plans to seduce him worked out.

Plus, there was one more added bonus.

By training his willpower to the extreme like this, at the end of the day, Naruto's willpower would be drained. He would be far easier to seduce in a state like that, where his resistance would be at it's weakest. Shizuku blinked, before a wicked smile came over her face when she realized that there were no downsides to what she was doing for Naruto.

1. She got a stronger ally.
2. She could use him to masturbate.
3. He would have a better body to please her.
4. He would be easier to seduce.

"... You're done for now ya know." Shizuku got off of his face, and she gave him a wash rag to wipe his body off with. She was sat to get off his face, but she wasn't done just yet. "With sit ups at least ya know..." Shizuku added at the end, seeing as she didn't want him to think he was done training.

"I'm going home..." Koneko got up and walked towards the door.

She had jobs she needed to do tonight for Rias, so she couldn't stay much longer anyway. She carefully moved Serafall's head, but the grown woman decided that she was needed elsewhere, and got up.

"I'm going to go play with... So-tan... see you next time Naru-tan." Serafall decided to point at the ground, and a small magical circle appeared. She marked Naruto's apartment as a location that she could teleport to and from. Naruto, exhausted, didn't even pay it any special attention. He just waved to Koneko and her, without even looking at them.

Even when Serafall used her magical circle to teleport, Naruto didn't register it, even when the magical circle vanished. Koneko just closed the door behind her, using the door like a normal person would.

"Finally nya!"

Kuroka came out of Naruto's room with an excited shout, finally allowed to be free once more. Don't get her wrong, she loved her sister dearly, but she wished the girl would have left hours ago. She had been stuck away from everyone for so long, and there had been so many things that she had been forced to watch from the open crack in the door. She went right towards the kitchen, and grabbed herself some ramen cups, since there was none of Shizuku's lunch left.

"I'm going to make dinner in a hour... wait... ya know." Shizuku deadpanned at Kuroka, but the woman just stuck her tongue out at her and continued on. Shizuku glanced at Naruto, who was training his willpower, and his servant who had no willpower to resist temptation. "... fine, no dinner for you then ya know." Shizuku pointed out.

Her chosen destination for Naruto to go on his run, had been the store so that she could grab a lot of good, healthy food.

"What is for dinner?" Naruto asked her, and she placed her hand against his stomach.

"... You're going to do squats until dinner is ready or you reach 1000 ya know." She gave his next assignment. Naruto groaned, but got into position and got started on it. Kuroka perked up, and she stopped making her a meal. She ran over to Naruto and jumped on his back, sandwiching his head between her breasts from behind.

"With me on your back!"

"We're going to be having steamed oyster, pomegranate and ginger smoothies, grilled asparagus, and for a nice desert I got a watermelon for a nice watermelon sorbet ya know." Shizuku went into the kitchen with a small, cocky smile on her face, knowing that neither Naruto or Kuroka were good enough cooks to make a good meal out of that on their own. Since they weren't exactly cooks, they wouldn't know what her ulterior motive was for why she chose each part of the meal.

It was all healthy, that was obvious, even the watermelon was healthy when made with less sugar, and fresh watermelon. Oysters were great for increasing dopamine levels and testosterone levels, something great for a training body, as well as being rich in zinc. Watermelon was good for the cardiovascular system and improving blood flow by relaxing the vessels. Asparagus was high in vitamin B, and even better, a type of vitamin B that was high in folate that helped histamine production, while also being steamed. Ginger helps increase blood flow and increase body heat, great for the metabolism, while pomegranate was perfect for reducing stress levels, improving mood, and increasing testosterone levels.

Her secret agenda?

Every single food that she was feeding Naruto was entirely aphrodisiacs, and for as long as she was cooking for him and training him, she would make sure that he stuck to a diet.

"Sounds good." Naruto mentioned with a groan of pain.

His body hurt so much right now.

'Using your willpower training to lower your willpower at the end of the day, using your training as a chance to get you used to my body sexually, and feeding you nothing but aphrodisiacs... I'll use your own training to increase my ability to seduce you.' Shizuku glanced back at Naruto with a sly smile, her tongue sticking out and flicking the air. Her plan wouldn't be something instant, she would need to keep him eating her food for several weeks, and she would need to condition him to get used to her body in increasing levels of nudity. She would also need to push his willpower to the limits every day, so that she could judge when his resistance was at it's lowest.

A snake never let go of it's prey, once it had a target in it's sights, and she wasn't going to let Naruto escape her. The best part, while she was seducing him, she wasn't technically doing anything wrong. Increasing Naruto's sex drive wouldn't force him into having sex, it would just increase his desire for it. Lowering his willpower was just a side effect of training his willpower. She wasn't changing his personality or anything, just getting him in a moment of weakness.

Kuroka really should have been doing this from the beginning, instead of pretending to be a pet cat.

"... I sense danger nya." Kuroka whispered and glanced at Shizuku, wondering what she was planning. She made eye contact with the elder ayakashi, and saw that Shizuku was looking right at her with a wide smile.

-After Dinner-

"... Going to admit... that was delicious..." Naruto wished it was ramen, but he had to admit that Shizuku was a great cook. She had even turned veggies into something that was pretty tasty, and he hated them. Shizuku glanced at Naruto, who was looking at Kuroka eating ramen (Shizuku refused to cook for her), and she sighed to herself.

Ramen was his food weakness.

She would make him a healthy ramen, once she could figure out a recipe that she could cook using her "Shizuku Approved Food" plan. It would have to be healthy, tasty, and increase his sex drive. She took pride in her cooking, cleaning, and pleasing skills. She smirked when she saw that Kuroka didn't even realize what she was doing, though she doubted Kuroka knew which foods held special properties.

The cat needed to up her game, before the snake stole the victory.
