Coffee and Donuts
Hours of research led Senpai to the best online algebra study resource in the country. The company hosting this algebra website also provided all his school's mathematics study materials, a fact that bolstered Senpai's confidence.
The site had a couple of drawbacks, though. First, the cost. The six-hour algebra tutorial he purchased wasn't cheap. But Senpai could afford it. He'd been making a name for himself in the art world, and one good painting would cover the cost.
The second issue was the site's layout. Navigating it required the use of both a keyboard and a mouse, often at the same time. The exercises required left-clicks, right-clicks, control-clicks, shift-clicks and a host of blended motions like "hold down shift to draw a line between selection A and B." Other sites offered simpler interfaces he could manipulate with just one hand, but their quality didn't compare.
I'm not going to half-ass this. She's got to ace this test, so she deserves the best.
On the plus side, Yoshi's hypnotized state was a blessing in disguise. Senpai's research into trans-like states suggested that anything taught to Yoshi in portal mode bypassed her normal conscious barriers and got placed directly into her subconscious mind.
Keeping her in portal mode via constant skin-on-skin anal contact presented a hurdle—he needed three hands; mouse, keyboard, and anus—but Senpai felt he had a workable solution to that challenge as well. He got the idea from a joke.
Who's the most popular guy in the nudist colony?
He reached for his phone.
But first, I've got to give un-hypnotizing her one more shot.
Though he knew the results beforehand, he held the swirl to her eyes, patted her head, and asked Yodie to turn back into Yoshi. As usual, she declined the offer. She was happy in her shell.
That'll change once we're done studying.
He felt confident that once she'd mastered the material, she'd return to her senses.
He leaned back against the sofa, legs together and straight, his feet warm under the kotatsu. He set the laptop on the tabletop, his wireless keyboard to his left, and his wireless mouse to his right. After logging into the website, he practiced Session One from the increased distance. Increasing the font size a couple of notches made things easier on his eyes, and he navigated the site without issue. Up and down, side to side, entering text, checking boxes, drawing lines—everything worked flawlessly.
All I need now is a student.
He retrieved Yoshi from the front door area where she'd been playing with a pile of random shoes.
Another mess I'll have to clean.
He clipped his leash to her collar and walked her back to the study area.
"We're going to start our study session now," he told her.
He lowered his pajama pants and returned to his tutoring position, placing his feet under the table with his back against the couch. Yoshi's eyes lit up. She lowered her lips toward his dick and sucked it into her mouth.
Senpai gasped. "Oh, boy." Once he was good and hard, he lifted her mouth off his appendage. She met his eyes with a frown.
"You can have more if you do what I say."
"Rowrf."
"I need you to turn your back to me and slowly sit down." Though she didn't understand a word he told her, she didn't resist when he guided her. He moved her so her back was to him, and her calves straddled his thighs.
He reached to the side for the lubricant he'd used to coat the tail-butt-plug and liberally greased up his pole. "Here comes the tricky part." He guided her hips and slowly lowered her bottom toward the tip of his shaft. She froze wide-eyed when the dome of his head seated in the divot of her anus.
She's in portal mode. So far, so good.
"I'm going to push myself all the way inside of you now," he told her, "so you're going to need to relax."
Instantly, her muscles softened and the head of his shaft slid inside. He lowered her further. Facilitating his gentle penetration, she arched her back and wiggled her hips.
Oh man, this feels incredible.
Senpai used all the willpower he could muster not to come. It seemed like an eternity before Yoshi's bum rested on his pelvis. He was all the way in. He wedged a pillow behind himself and adjusted his posture, leaning back while Yoshi kneeled, her arms at her sides, her back straight at full attention.
That isn't too bad.
He cupped her shoulders. "Yoshi, are you okay?"
He translated the sphincter-squeeze of his dick as a "Yes," though it nearly made him come. Senpai closed his eyes and fought for control. Though the snug warmth enveloping him felt phenomenal, he had to resist his urges. He breathed deeply until the need to climax subsided.
Then he allowed himself a chuckle.
Who's the most popular guy in the nudist colony? The one who can carry two mugs of coffee and half a dozen donuts.
He marveled at the stack of donuts sitting on his lap.
He'd placed his equipment perfectly. He could clearly view the laptop screen placed slightly off to the side, and Yoshi, with her portal wide open, could clearly see it too. His keyboard and mouse remained in easy reach.
"Are you ready to study some algebra?" he asked.
Her ass squeezed his dick. Yes.
This is going to work.
Yoshi remained calm and attentive as Senpai went step-by-step through the instructions on the first page of the crash course.
"You simply have to imagine variables as containers for numbers," he told her as he scrolled the screen. "You substitute a three for the 'X' and a two for the 'Y' and work it out using normal addition. Are you following?"
Yes.
"Excellent. Then let's move on to the next page." He tapped the arrow key.
Twenty minutes into the session, he felt his dick softening. Focusing on math had actually caused him to forget about the sexy nude blonde currently getting her ass speared by his shaft reverse cowgirl style.
He shifted his hips. "Oh, shit."
Sensing his predicament, Yoshi rhythmically raised and lowered her bottom. Her subtle motions quickly induced the desired effect. Once his dick had adequately hardened inside of her, she rested her bottom on his pelvis.
"Wow." He took a deep breath and expelled it. "Thank you."
As the tutoring session continued, they tuned in to each other's cadences and rhythms in both training the brain, and maintaining the portal. Yoshi kept Senpai hard. In turn, Senpai kept Yoshi attentive. It took them ninety minutes to work through the first quarter of the course.
"Very good," he said after wrapping up the chapter's last sample problem. "Are you understanding all of this?"
Yes.
"My balls are about to explode, so we need to take a break. Thirty minutes, okay?"
Yes.
He guided her hips upward and eased her off his dick. Once her anus cleared his shaft, the energetic puppy came alive. "Rowrf." She shook, rolled, and stretched, working all of her stiffened muscles, before rushing him on all fours, and pouncing on his throbbing dick.
Who's the most popular girl in the nudist colony?
Yoshi mewed contentedly as her master's tasty cum gushed into her mouth.
The girl who can eat all of the donuts.
Yoshi took her post-meal crash to the couch where she curled up into a ball and rested. Senpai rose, shook out his legs, and patted her head. "Only three more sessions, girl." A hunger pang accompanied his gut's deep growl. "I better get some food in me too." While Yoshi snoozed, he raided the fridge and the pantry.
Senpai easily maneuvered his pupil into position for their second session. Actually, Yoshi did most of the work. Sitting quietly, she remained attentive, her portal open, as they breezed through one algebra lesson after the next. She savored her creamy meals during their breaks, while Senpai tanked up like never before to keep the hunger pangs at bay.
I guess I'm eating for two now.
At one point, while reviewing an example problem, Senpai said, "So the answer here is 'C', because the square root of nine is three." When Yoshi didn't acknowledge his claim with a Yes, he asked her again, "Do you see that?"
When she remained silent, he went through the problem from the start. "Oh, I see. The answer is 'D' because when you take a square root you've got to consider both positive and negative initial values."
Yes.
"Good catch." He rubbed her shoulders. "Way to go."
Including breaks, meals, and an outside play session, they spent ten hours poring over the crash course and bonus materials. After they finished the last session, Senpai cupped Yoshi's breasts, pulled her close, and kissed her neck. "I can't believe we made it to the end." He rubbed her head. "Do you think you know your stuff?"
Yes.
"I believe you know it too. Let's let the information percolate in your brain overnight. Then tomorrow morning we'll do the sample test, okay?"
Yes.
He eased her off of his shaft. They ate, and they went to bed. The following morning, Yoshi woke Senpai in the usual manner at 10:04AM. The rains ceased and the sun shined intermittently when they followed their routine in the backyard. Once again, he scrubbed his pet clean in the tub, and she watched contentedly, curled up on the floor, as her master showered himself clean afterwards.
After breakfast, Senpai set up the study area.
"Ready to take the sample test?"
"Rowrf." Yoshi sucked Senpai's study shaft to its proper hardness, straddled his legs, and gently lowered herself onto him.
"Here we go." Senpai clicked the clock image, starting the timed multiple-choice test. As they moved from one question to the next, Senpai hovered the mouse pointer over the selections and clicked when his pupil said, Yes.
Yoshi finished with time to spare and got all but one right. When they went back to check on the problem they'd missed, it turned out the correct answer was ambiguous.
"I still think the problem simplifies down to the equation X-squared minus Y-squared," he told Yoshi. "I guess it all depends on how you define the word 'simplify.' Do you want fewer characters or more work? It's not intuitive.
Yes, Yoshi agreed.
He ran the equation through his head. "It still doesn't make sense to me. Should we go forward or reverse? Does it even matter?" When he checked the reference chapter, a light lit above his head. "Okay, now I get it. They're doing it right if you follow their rules, which, I guess, are the rules of algebra. You have to reverse the process here." He pointed to the equation. "Then it'll come out right every time."
Yes.
"Keep that in mind come test time, okay?"
Yes.
"Good girl." He rubbed her head.
After Senpai eased her off of his shaft, Yoshi dropped out of portal mode with a full reserve of energy. She scampered around, pounced on top of him, and licked his cheeks. "Rowrf."
His phone chimed. He reached behind his head and snatched the device off of the couch cushion. Nagatoro had texted him.
"Hey Senpai," she wrote. "We're back on the road. We should get home by 5:00PM. Want to hang out?"
He checked the the clock. It read 2:20PM.
"Yes, I…"
As he tapped his reply into the phone, Yoshi sucked his dick into her mouth and playfully bobbed up and down on him.
"…would like…"
His pleasure levels spiked.
"…that."
"Will your parents be home?" Nagatoro asked.
"It's not likely," he replied.
Oh, boy.
"You know what that means." Nagatoro added a winking smiley face.
He continued tapping. "I'm looking forward to coming…" Oh, shit. "Aaaahhhhhhhh." As a wave of bliss rolled over him, he gripped the phone and it chimed. "Nuts. I sent that."
"I'm looking forward to your coming home," he corrected after regaining his bearings.
I can't believe I did that.
"I know what you meant, pervert Senpa!" came the reply, followed by a string of smiley faces. "I can't wait either. See you soon!"
"Look at what you made me do." He wagged his finger at Yoshi, who smiled at him through puffy chipmunk cheeks before scampering off.
After closing the texting app, the icon for the hypnotism app glowed as the words "forward" and "reverse" popped into his head. His jaw dropped.
"No, way."
He started the hypnotism app and checked the settings. All the times he'd worked with her, the swirl he used moved in a clockwise direction, sucking her attention into the center of an imaginary abyss.
The swirl moved in the exact same direction when he used the effect to try to un-hypnotize her. But what if that made things worse? As a puppy, she didn't understand words. She only saw the swirl, which reinforced the initial suggestion.
What if I…?
He changed the app's settings and set the direction slider to reverse. Instead of the swirl sucking her into the void, it now turned counter-clockwise, pushing her out. Was this the answer? The timing sure as heck couldn't be better.
I think this might work.
He carried Yoshi up to her bedroom, fastened the cuffs around her wrists and ankles, and put her in her cage. As she mewed peacefully atop her mattress, Senpai cleaned the house. Forty minutes later, everything looked spick and span, and he'd packed all his stuff.
She opened her eyes when he rubbed her head, and opened her mouth when he held his finger to her lips. After getting his digit nice and moist, he slid it into her anus. Yoshi's eyes widened and her body stiffened.
"Your parents are going to be home in a few hours, so it's time for me to go. I feel confident that you know your algebra. Do you feel confident?"
She squeezed his finger, Yes.
"Good. So you've got nothing to be afraid of. You're going to ace the test tomorrow. It's time to break the spell and come out of your shell. It's time for Yodie to become Yoshi again."
She did not squeeze his finger.
He pulled his phone out of his pocket and held the screen to her eyes, this time with the black and white swirls turning in the opposite direction.
"Close your eyes and relax." When she complied, he continued. "Listen carefully to my directions. I'm going to remove my finger and pat your bum. When I do, you're going to fall into a deep, restful sleep. When you wake up, you won't remember anything that happened this weekend. You went straight home by yourself after you visited me on Friday night. We did not spend the weekend together. All you will remember is studying for the algebra test. On your own. I was never here. When anyone asks what you did all weekend, you will say… I studied for the algebra test. I studied for the algebra test. I studied for the algebra test."
In a voice he'd almost forgotten, Yoshi whispered, "I studied for the algebra test."
When he eased his finger out of her ass, her body relaxed. When he patted her bare bottom, she collapsed into her mattress like a puddle. He removed the leather cuffs and collar, positioned her onto her back, and pulled the covers over her body. She rolled onto her side and snoozed peacefully.
After leaving her keys on her desk, Senpai closed Yoshi's bedroom door, then double and triple-checked the house to make sure he left everything clean and in order.
He locked the front door and walked home.
Author's Notes: Will she remember anything or won't she? How will Yoshi do on the test? I think we all know the answer to that last question. Nagatoro is returning home, marking the end of the Senpai-Yoshi arc. I know this arc got a little intense and I apologize to the readers sensitive to the mature themes I broached. Also, sorry for taking so long to finish the damn thing. Going forward, I'll try to add one chapter per month. — SK
