Story: Friendly Hentai Tome

 

As she approached the home of Hinako Ninomiya, Nabiki started to feel like something wasn't quite right here. Why was she, a high scoring student, heading to a teacher's home for extra tutelage? That didn't make a lot of sense, did it? The closer she got, the less certain she became of this. She ought to turn back, right..?

Yet she continued on her way regardless, curious why she was feeling this way. There must be a reason for it. Why couldn't she figure out what it was? And why did she feel this pleasant pressure on her lips whenever she tried to think through it too hard...? Maybe Hinako herself knew. Or maybe her friends could tell her?

In time, she arrived at her destination and knocked on the door, feeling more confused than she normally did. The door opened, and Daisuke was there to greet her.

"Hey buddy!" he said, putting his arm around her shoulder and guiding her inside. "You're the last one here, so..." His hand slipped down her back and settled on her butt, which he gave a nice big squeeze. "So glad you're doing us all a favour like this, and helping us study."

Inside, she found the teacher in her adult form, sitting in Hiroshi's lap, while not too far away both Yuka and Sayuri - two of Akane's friends - were dancing around in their underwear. Weirdly, this sight sort of set Nabiki's mind at ease. It was all a bunch of friends hanging out together.

"You know our grades kinda suck, right?" Daisuke asked. His big squeeze grew bigger. "It's so nice of you to do us a favour like this and help us out, you're such a good friend."

"Yeah, yeah," Nabiki replied, eyes on the teacher. "Say, how long has she been in adult form? You guys seem pretty lively, so..."

"We worked out a way to keep her adult for as long as we want," Hiroshi said, reaching up to her head to tilt her chin and give her a deep, deep smooch while his other hand groped her breast. "We're such good friends, aren't we?" he asked when he was done.

"Yep," Hinako replied, in a tone quite unlike her usual adult self. It was more like her, let's say, less mature version speaking just then. "This is such a super duper helpful thing you're doing for me right now! Thanks a lot!" Then her tone shifted. "Now, let's return to focusing on these questions. I can hardly believe you're this behind on your mathematics."

Nabiki sat down in Daisuke's lap and, because she was such a good friend, let him grope her boobs and kiss her neck. As a favour, you see. She was doing him a solid right now. Although it did make her wonder what, exactly, she was doing her right now? How was she going to help them improve their grades...? She looked around the room. Saw the two girls dancing erotically for them. Saw Hinako sitting in Hiroshi's lap, letting him paw at her body all that he wanted. Thought about herself, sitting in Daisuke's lap, having no issue at all with him doing the same to her...

"Hold up!" Nabiki pulled herself to her feet. "Hinako, please get off of his lap, right now! This situation, it's all wrong. We shouldn't be letting these perverts play with our bodies like this."

"Eh?" Daisuke squeaked.

"Oh no!" Hiroshi yelped.

Nabiki stepped to the side and leaned over to wag her finger at the two of them. "I see your game," she said. "You brought us here so you could fool around, right? You're not getting away with that. Not now that I'm here! I'm wise to your tricks."

The two boys turned white as a sheet. Heh. Thought they could get one over on Nabiki Tendo, did they?

"You should only get to play with our bodies once you've proved you can improve your grades!" Nabiki said. Hah! Proud of herself for that one! "You'll get some of this if you can show you can study properly!"

"Excellent thinking, Miss Tendo!" Hinako bounced to her feet and put her hand on her hips. "You want some of this? We~ell boys, you can get some of this when you, ya know, show you deserve it~ Teehee!"

Sort of shifted through her adult to childlike personality there for a bit. Ah, that was kind of cute in its own way. Regardless, the boys seemed to relax a bit - but only a bit!

"Uh, excuse us," Hiroshi said. "We need to... uh..."

"Go to the kitchen and get you girls something to drink," Daisuke finished for him. "Come on Hiroshi, let's get them some lemonade! You girls keep yourselves entertained for a while, we won't be long!"

<hr>

The two of them ducked into the kitchen and quickly closed the door behind them - then deflated like a pair of released balloons.

"Oh gods above I thought she was onto us," Hiroshi whispered, relieved that this had not come to pass. "I thought she was free from our influence."

"She's not all the way out yet," Daisuke quickly added. "That girl has taken control right out from under us with that suggestion!"

The two of them understood that in full. They couldn't protest Nabiki's idea without pushing the girls to the limits of 'friendship' and 'favours' which they had carefully cultivated. Yet if they went along with this idea, there was a risk of a repeat of what happened with Akane, where they went too slow and made her into a fellow pervert instead of having her join their harem!

"We got greedy," Daisuke said. "We thought we had the hang of it, and went after two babes at once."

"Hrm, maybe we should stick to one at a time in future?" Hiroshi said. He rubbed his chin thoughtfully. "Either way, I don't see any other way out of this mess. We're going to have to study up, and get those chicks laid pronto!"

The two of them shook hands, concluding this was the one and only way they were going to get through this mess. Cooperation! That was the key! All they had to do was answer a few study questions correctly and then they'd be getting all the action they could handle!

"We're not getting laid at all tonight, are we?" Daisuke asked.

"Oh, definitely not!" Hiroshi replied. "But dammit, we gotta try! We can't just give up that easily!"

The two of them quickly poured out some lemonade for the girls to enjoy. Put a few ice cubes in there as well. Heh! Maybe they could do something fun with the ice cubes, like getting them to rub them down their neck or something? That would be a fun reward! From there, they left the room eager for once to get on with studying, and when they left they found...

Yuka sitting in Hinako's lap, burying her face into the teacher's chest, while Sayuri was laying on the floor next to Nabiki giving her a very obvious, sloppy french kiss.

"Think of this is a little extra motivation," Hinako said, setting out the books in front of them. "A taste of what you'll get if you demonstrate you can improve."

The two boys sat down, but something else was sitting up. They nervously swallowed, grabbed a pencil, and stared at the questions before them. Find an area under a curve, huh...? That was an old, easy joke but somehow they felt like they wouldn't be getting the chance to do that anytime soon!
