A Day/Night with Nagisa

Chapter 3

Two days later…

Tokyo

The elevator brought Nagisa up to the top floor of the fancy apartment. Stepping off, he walked down the hallway until he reached the door to the suite apartment that belonged to his old friend, Kayano. It was Saturday so he didn't have to teach today. After spending most of the day with his girlfriends, he'd received a call from his old friend, wanting to catch up with him since she had a gap in her schedule in between roles.

Walking up to the door, Nagisa checked the bag of hair product that his girlfriends bought as a present for Kayano before ringing the doorbell. After waiting a few seconds, the door opened up and he saw his old friend.

However, he wasn't quite expecting her to be wearing the outfit she had on.

Kayano's long, green hair had been tied in a corkscrew pigtail, which was a different look for her. But what really caught his attention was her new outfit. His former classmate wore a tight black and white crop top with three golden lines traveling vertically across her busty chest. A small black belt at the bottom of her crop top kept it nice and tight. Her belly was on full display, showing just how thin and toned she kept herself. The miniskirt she wore matched the pop tone of her top. One half was white while the other half had a checkered gray and black pattern, two small black straps on the front keeping it from tied together. It being so short, it looked like her panties were about to peek out if she leaned in any particular direction. With her white bracelets, ankle boots and a matching thigh strap on her right leg to finish the look, Kayano looked like she was about headline a concert.

"Nagisa! It's so good to see you!" The skimpy-dressed actress hugged her old friend, glad to see the preferred reaction when he blushed at her appearance. "How've you been?"

"I'm great, Kayano." Nagisa's thin arms hugged her back. "What's with the outfit? Did you join a band?"

"Oh, this?" Pulling away from Nagisa, Kayano smiled at her friend and gave a little twirl while giggling. "You like it?"

"Very much," said the eager Nagisa, finding her to be cuter than ever.

"Come in and I'll explain. Oh! Is that the hair product Kanzaki promised?"

After handing her his girlfriend's gift, Nagisa followed his old friend into her apartment and into her bedroom. Walking over to a beauty station in the corner, Kayano pulled out the gift from the small bag and set it on her table. "Anyway, yeah, the outfit." Turning back to Nagisa, Kayano gave her answer. "The studio wanted to shoot a promo movie for this pop idol group so they had me dress like this for the day. I can tell you like it." She gestured for Nagisa to sit down on the edge of the bed and sat down next to him. Grabbing hold of a remote, the actress turned on the tv and showed her old friend a few clips of the movie she'd made, showing off her singing and dancing skills.

The two friends shared a comfortable silence as they enjoyed each other's presence and watched the video together. It'd been a while since the pair had seen each other; even longer since they'd been alone like this. Kayano laid her head on Nagisa's shoulder, slipping her hand into his and giving it a small squeeze. That jealous part of her that she couldn't deny always wished that it was her that was Nagisa's girlfriend and not Hayami and Kanzaki. But she was content being one of his fuck buddies whenever the opportunity arose.

Speaking of which…

When the video ended, Kayano turned off the tv and tossed the remote onto the bed behind her. "So, um…when I was talking to Kanzaki, I asked if she and Hayami were okay with you…" Kayano leaned forward, her hot breath hitting Nagisa's ear. "Staying the night with me."

Nagisa did nothing but smile. He wasn't surprised when Kanzaki asked him to head over to Kayano's apartment all by himself; all of his former female classmates were his fuck buddies so there were few days when he wasn't balls deep in a woman's pussy. Hayami and Kanzaki were okay with Nagisa fucking their old friends, provided the girls made sure that Nagisa didn't knock them up. If anything, Nagisa enjoyed having a nice one-on-one time with his old friend. Despite being in a relationship with his two girlfriends, part of him will always care deeply for Kayano. To share a night with her alone was among his life's best gifts.

Slipping an arm around her, Nagisa pulled her close. Her warmth seeped into his small body as he held her in his arms. His answer came in the form of a sweet kiss. "I'd love to, Kayano…"

Smiling warmly, the greenette ran a hand up his chest before returning the kiss. "Take off your clothes and lie down for me," she whispered.

Sliding off the bed, Nagisa unbuttoned his shirt before letting it fall to the floor. Stepping out of his shoes and tugging off his socks, the schoolteacher unbuckled his belt to let his pants join his discarded clothes. Kayano rubbed her legs together when his underwear became the last article of clothing to go, his third leg already started to rise.

Doing as his friend asked, Nagisa got back onto the bed and laid down on his naked back. Kicking out of her boots, Kayano crawled on top of Nagisa's naked body, slowly dragging herself across his bare skin, making sure to brush her breasts and exposed belly against his hardening cock as she made her way up his body. As soon as she reached his face, the actress caressed her old friend's cheeks before planting another kiss on his lips, this time one with much more passion and tongue.

Nagisa's manhood became trapped between Kayano's smooth thighs, her skirt so small that his cock slipped underneath it. Nagisa wrapped his arms around his sexy friend, hugging her tightly while they continued to make out. Their tongues lewdly collided while they enjoyed the feel of each other's bodies. Nagisa's shaft rubbed against Kayano's panties, making her womanhood moist from feeling his hard girth touch her soft panties.

Sucking on his fuck buddy's tongue, the horny schoolteacher slid his hands down her back, slipping underneath her miniskirt and grabbing her soft ass. Something that he'd always appreciated about the greenette was her soft bubble butt. She may not have been their old English teacher but the girl was certainly not the flat chested teen that the other girls once teased her for being. Kayano opted to not wear a bra so he could feel her nipples hardening and poking through her thin tank top. Rolling over to lie on top of his friend, Nagisa cupped Kayano's breast, teasing her by pinching her nipple through her top. "Mmmmmh!"

Rolling back over so that Nagisa was on his back, Kayano decided to do something about the warm, wet ache in her loins. Getting on her knees, the actress slid her small hands underneath her miniskirt and quickly slid her green lace panties down her legs, letting them fall past her feet before tossing them to the floor. "Stay still. There's something I've been wanting to do," she asked while settling herself into position.

Grabbing hold of Nagisa's ankles, Kayano spread the small man's legs apart before she slowly lowered herself down onto his cock. "Mmmmhh! Oh yeah…" she moaned when his head slipped inside of her, her womanhood slowly devouring his cock as she slid down. "That feels so good…" Feeling him fill up her pussy, Kayano gave herself a moment to adjust to the size of the large meat log lodged in her cunt before she started to move.

Kayano's choice of position sparked little surprise in Nagisa. Some of his other Class 3-E fuck buddies liked to choose that particular position, giving them the confidence to try and conquer his huge cock. Although personally Nagisa enjoyed the position since it was fun to watch the girls constantly lose that struggle to overcome his cock.

The bed shook as Kayano started to bounce on Nagisa's cock, slamming her hips up and down. The greenette actress smiled as her womanhood was reshaped to match the size of Nagisa's cock. Her soft bubble butt jiggled each time it collided with Nagisa's hips. A side effect of injecting herself with antimatter tentacles during her quest for vengeance was that it gave her increased stamina. Combined with the muscles she gained from workouts she needed for some of her movies, she had enough strength and endurance to match the horny Nagisa.

Throwing his arms above his head, Nagisa laid back and watched the actress bounce wildly up and down on his cock, her tank top threatening to tear from the bouncing titties it contained. "Kayano! That feels great!" he moaned, his back arching when he felt the greenette squeeze his shaft with her inner walls.

"Ah! Ahh! Ohhh!" Tears stung the edges of Kayano's eyes. She felt the tension inside her about to burst. "Fuck! I'm gonna come !"

Gripping the sheets, Nagisa groaned as his balls tightened. "Me too!" His toes curled while his body tensed up. "I'm gonna blow!"

"Inside!" pleaded Kayano, her expression becoming absolutely slutty. "Come inside!"

Kayano reached climax first, her pussy tightening around the thick clamhammer wedged inside her before her love juices gushed through her plugged cunt. Letting go of what little control he had left in his body, Nagisa gave a groan before giving the greenette actress exactly what she wanted, his cock erupting inside of her and pumping her womb full of hot, white cum.

Feeling her womanhood being blasted with cum, Kayano let go of Nagisa's ankles and let herself fall on top of him. The two friends panted for breath, Nagisa's chest covered in a light sheen of sweat. "Mmmmmh…" Wrapping her arms around his thin shoulders, Kayano laid her head on his shoulder and basked in the afterglow, the heat of his seed in her womb making her feel like all was right in the world.

Finally, the greenette looked up at Nagisa. "You want something to drink?"

"Yeah, that would be great."

"Wine or juice?"

"Juice. I don't want to get drunk whenever I'm someone." Nagisa didn't want to wake up the next morning with a seering headache. He once had a drunken threesome with his girlfriends and after waking up feeling like the sunlight was stabbing at his brain, he

"Good choice."

Getting off of Nagisa and letting his cock slip out of her, Kayano walked out of the room. Putting his hands behind his head, the blue-haired schoolteacher waited patiently for her to return. After a minute, the actress returned with two glasses full of juice. Sitting up, Nagisa took one of the glasses and took a sip, the sweet juice hitting the spot after such wild sex.

The two enjoyed their drinks, letting their bodies cool down for a minute. Once their drinks had been consumed and their glasses were emptied, Kayano took Nagisa's from his hand and set it on her nightstand. "So then, back to it?" she asked, climbing onto his lap. Smiling as she pressed their foreheads together, Kayano whispered softly, "You can fuck me in any position you want, Nagisa. I'm all yours tonight."

Nagisa eagerly captured her lips in another long, sensual kiss. His hands went to her crop top, slipping his small fingers underneath the bottom of it. Lifting her arms, Kayano let Nagisa pull her crop top over her head, her sweaty breasts bouncing free. Kayano leaned back in Nagisa's arms, letting him bury his face in her soft tits. "Ooooh!" Kayano's head rolled back, her body going limp in her lover's arms while he indulged in her breasts. His tongue licked up her soft mounds like they were two scoops of ice cream. "Nagisaaaaa…" she slurred when he started suckling her nipples.

After getting his fill of his friend's titties for the moment, Nagisa pulled his head away from her cleavage and gave her soft ass a smack through her miniskirt. "Go lean against the wall," he ordered her.

Nodding, Kayano slid off of his lap and got off the bed. Walking over to the wall, the greenette actress leaned back against the wall. Getting off the bed, the naked Nagisa walked over to the eager woman and lifted up her right leg. With her leg raised, the front of Kayano's miniskirt was lifted up to reveal the woman's vulnerable pussy, giving Nagisa the perfect position to slide his manhood back into her.

"Ah!" Kayano's arms once again returned to Nagisa's shoulders as he started to fuck her in standing missionary. The intimate angle let the schoolteacher's manhood grind against all of her sweet spots with every thrust of his hips. "Ngh! Yes! It's…so good!" cried out Kayano. "Fuck! Fuck me! Fuck me harder!" Her nails dug into Nagisa's shoulders while her pussy tightened around his thick clamhammer.

The pair of lovers moaned uncontrollably while Nagisa continued to fuck his friend standing up. Kayano regretted not setting up a camera so she could watch this later on whenever she felt lonely. 'Oh well. Next time…'

Hitting his stride, Nagisa lifted up Kayano's other leg and let her wrap both legs around his slim waist. Pressing her against the wall, the horny schoolteacher let his hips go into overdrive. "Ah! Ahhhhh!" Kayano's moans grew louder by the second once Nagisa's cock returned to battering her cunt, churning the cum still fresh in her womb. "Fuck me! Ah! Ah! Nagisaaaa!"

The thin man continued to fuck his friend into the wall, eagerly watching her face contort from the pleasure. Her bouncy breasts pushed against his chest, making a pleasurable heat develop inside him as their hard nipples touched. As Kayano's head turned to the side, Nagisa took advantage and started to attack her with soft kisses and licking her sweaty skin.

Digging her heels into Nagisa's back, Kayano let the room echo with her moan of ecstasy, her body tensing from impending orgasm. "Fuck! I'm coming! Ah! Ahhh!"

Nagisa didn't slow his hips down even as her gushing hole became tighter, pumping in and out with the same strength and speed that made him such a stud. Grunting hard into Kayano's ear, Nagisa gave the actress everything he had, his cock hitting all of her sweet spots over and over. "Nghh! Ngh! Ugh!" he grunted, sweat pouring down his back. "I'm gonna…come!"

Kayano clung to her lover, turning his head to face her and smashing their lips together. Nagisa's moan was swallowed by her hot lips, Kayano tying their tongues together as she climaxed along with him, her pussy squeezing his cock tightly while milking him. The actress felt nothing but total bliss as her womb was filled. She was half tempted to go back on her word to Kanzaki and Hayami and stop taking birth control so she could have Nagisa's child. 'We would make cute children, after all…'

But the thought was dismissed just as quickly as it came to her. She knew having a child would ruin her career as an actress and Nagisa already had enough rambunctious kids to deal with now that he was a teacher. Plus, Kanzaki and Hayami would be beyond pissed if the greenette broke her promise to them and got knocked up.

His cock spent, Nagisa pulled his lover away from the wall and carried her over to the bed, laying her down on it and pulling out. Panting for breath, Nagisa laid down next to her and pulled her close. Kayano shared a sweet kiss with her old friend, her hand going down to stroke it. Nagisa returned the favor by reaching around the curvy actress to squeeze her soft ass. "Wow, you must have been pent up," she noted as the heat in her womb reminded her of how much the man had let out inside of her.

All Nagisa did was chuckle. 'Yeah, I've been pent up…for about two hours…' Before heading out to go meet up with Kayano, Nagisa indulged himself with a quickie with Hayami. "So then, looks like it's still pretty early into the night…" he said, glancing over at the clock.

Giggling, the green actress stood up on her knees. "Looks like we've got a lot of catching up to do." Turning away, Kayano unclipped her miniskirt, tossing it onto the floor. Now fully nude, she got down on all fours, shaking her perfectly peachy ass in front of Nagisa enticingly. "My little pussy's a little lonely without your cock, after all," she said in her most seductive voice.

Nagisa eagerly sat up and mounted the actress, the two going at it long into the night. Although they could be nothing more than just friends with benefits and his heart lay with Kanzaki and Hayami, tonight Kayano was all his and he could indulge in his old feelings for her.

It was a good thing for Kayano that Kanzaki had given her the hair product; she was going to need it in the morning when she woke up after being fucked silly all night long…
