A/N: Rated M...again. This chapter is full on smut. You've been warned. I'm probably going to write a prequel to show how they first meet in the near future. If you enjoyed it, feel free to leave a review, it would be much appreciated! :)

The walk back to Ginpachi's apartment was definitely not of standard affairs. Instead of walking alone at night with a sauntering or zombie-like demeanour, it was now one that looked much more natural, even lively for his standards with a new (or old on this case) companion while the full moon was up. Even when he walked up the stairs to his relatively decent if slightly untidy apartment it didn't take him anywhere near as long walking up as he usually did. Even opening and closing his door used to feel like a chore, but it was much swifter this time when she almost tackled him after opening the door and dove straight into his mouth. He may still have a stack of papers in his duffel bag to mark but he could probably catch up on it later. Right now, the only thing on his mind was catching up with his old acquaintance in their own unique way, all the while lustful moans and loud lips sucking echoed throughout the living room.

The two shook off their shoes as Ginpachi guided Tsukuyo straight to his room. It was fairly small, enough to house a small PC and desk, his wardrobe and a bed. The rest of the space was taken up by neat piles of JUMP magazines and mangas associated with them. They dumped their bags on his floor and hurriedly took off their lab coats before Tsukuyo messily took off his tie, flinging to a nearby corner and proceeded to unbuttoned him, desperate to get straight to the action. Ginpachi did the same, unbuttoning Tsukuyo's shirt and taking it off before he could feel himself gently flop onto his bed. Oddly enough she didn't jump on him straight away, but instead walked over to her bag to pick something up.

"Don't tell me you've got handcuffs in there." He joked, but his eyes widened once she got them out and started putting them up to her thighs, instantly aroused by what she was wearing before she removed her pencil skirt as it dropped to the floor, leaving her in her black laced bra, panties and fishnet stockings.

That's my weakness.

He didn't say anything as she slowly climbed onto his bed, smirking with a devilish, lustful look on her face as admired what layed beneath her.

"Just like old times hm..."

Tsukuyo decided to take her time advancing to him on his bed, slowly crawling on all fours. The way she crawled was both sexy and alluring yet somewhat sinister to him, like she was dying to quench her thirst for him. The way she trailed her fingers up his chest wasn't helping either. He was already sensitive to her touch, and feeling them sent shivers up his spine, all the while straddling him at the waist.

She sat up for a brief moment to release her hairpin that kept her hair up, letting it fall freely down to her shoulders before she leaned down to him. She looked incredible, her figure bathed in the moonlight that shone through his window into his room, and her amethyst eyes gleamed in its light. Like a goddess that descended to earth. As she leaned closer to lock lips with his, his hands naturally gravitated towards her lower back and ran up and down it. The sound of their lips slowly sucking at each other as well as the moans from both of them as their hands trailed up and down their bodies was a clear sign that they still loved each other dearly. The glazed looks they gave one another as they pulled away showed nothing had changed. No ill will or underlying tension could get in the way of their passionate desires.

"You haven't changed at all have you..." He remarked with a grin as his hand trailed down her back to rest on her smooth rear.

"Course not." She smugly replied as she kissed his neck, leaving him to moan slightly as his hands gently squeezed her butt before moving one up to rest on her cheek for another long, tongue filled kiss. It felt heavenly being in each other's company with no one to disturb them. She sat up and rocked herself forward vigorously, instantly causing Ginpachi to groan quaveringly as she continued grinding herself against him.

"Shall we pick up where we left off?" She asked sarcastically, lowering down to take off his pants and boxers. With Ginpachi's help, she dropped them onto the floor with the rest of their strewn about clothes, leaving him naked and his third leg standing up at max height.

The first contact with her mouth and his cock instantly sent Ginpachi's hands grasping for her hair for support as she continued her private lesson in health education. This time she added in swirling licks around his balls to the tip as well as tickling his tip repeatedly with light licks from her tongue, which was breaking Ginpachi's sanity apart as he watched her head slowly bob up and down. When it felt like a prolonged silence, she returned on the attack with more slow licks, gradually eroding Ginpachi's state of mind.

"Hah-Hah-Hah-"

This is so hot...but I'm not gonna last if she keeps doing that! I was gonna blow the first time anyway!

His hold tightened when he felt his entire length being engulfed by her mouth at an agonisingly slow pace as she hummed in pleasure, making him groan loudly out of rapture and frustration. He instinctively started thrusting in her mouth out of desperation as a sign to quicken her pace and that he was nearing his peak. She was taken off guard slightly by his sudden thrusting but welcomed it nonetheless, even more so when she felt her head being gently pressed down by him, as if he was wanting more of it.

"Arghhh-Shit-shit-shit-shit-Ahhhh..."

His eyes and teeth were shut tight as he carried in thrusting in her mouth, controlling his breathing through short, sharp gasps as he desperately tried to hold himself back, only for his hips to involuntarily surge upward as he cried out in a fit of ecstasy and quavering groans, feeling his cock letting loose its contents at irregular intervals. He continued slowly thrusting out of habit before he went to a standstill as he felt her mouth withdraw.

His mind was completely scattered but gathered enough presence to suspect that she took it all in. To say that he lost control was an understatement when he heard a swallowing sound followed by licking lips, making him sigh deeply and covered his face with his hands in utter despair.

"Ya alright?"

"No...you fucking sadist." He answered apathetically. He wanted to cry after losing himself so early in front of her. He could practically feel himself tearing up as he opened his eyes to stare soullessly at the ceiling, distraught with the fact that he came in her mouth AND finished before they even got started like a complete amateur. He completely ignored Tsukuyo's movements as she crawl up to him once more, lowering his chin down to face her sympathetic smile.

"Don't beat ya self up over it, we can still rehabilitate ya..." She delicately reassured him before sliding her tongue in his mouth. He could taste his own bitter, salty fluid in her tongue. It was revolting but strangely erotic that he was getting a taste of himself, and sharing it with Tsukuyo no less. As they drew away they stared at each other with glazed eyes.

"That tastes disgusting..." He dreamily mumbled.

"Wrong. It tastes hot." She replied with a smirk, shuffling back down to gently massage his deflated third leg with her hand. He reacted instantly by gasping quite loudly, still sensitive from her touch after letting himself go earlier.

"Arghh...Wait-wait- wait- Haaahh..." He groaned quaveringly as she continued to stroke him up and down before being suppressed by another tongue-filled kiss. He moaned louder and louder in her mouth with each languid stroke before she withdrew her mouth and set her sights on his dick.

"Relax, just gonna help ya out..." She whispered before sinking her mouth down his length again, slowly bobbing her head up and down once more. Ginpachi rested his hands on her head as she did her work at a more languid pace, his breaths still sharp gasps but felt more stabilised. He was even starting to feel slightly more relaxed as he exhaled softly each time her mouth reached the tip before starting from the bottom again. His hands loosened up and rested on her shoulders as she raised her head for another slow kiss. She let slide the fact he unclasped her bra strap to let her breasts loose as she leaned in, gently moaning as he slowly kneaded her breasts.

"Better now?" She asked softly whilst wiping her mouth, to which Ginpachi hummed happily in response. From that positive indication, Tsukuyo sat up and straddled him, gently rocking herself back and forth as a way of preparing herself for her next move. She shifted her panties slightly to free up her core as she slowly inserted herself in him, making her yelp slightly as she sank down.

"You ok?" Ginpachi asked with a raised eyebrow.

"I'm fine." She nodded slowly. "Oh before ya ask me, I'm on the pill. So don't worry about getting a kid from all this." Ginpachi blinked at hearing this. He completely forgot to bring condoms with him.

"Y-you sure? I don't want to risk you getting pregnant. You can still pull out if you want." He said looking rather concerned. She shook her head, seeming perfectly content with what she was going to do next.

"Trust me, I'll be fine, so don't worry about it, I want to do this anyway. I'm happy ya worried about me though. I just want ya to relax..." She whispered reassuredly, slowly bouncing up and down, gradually causing them to start panting almost immediately.

Up. Down. Up. Down. Ginpachi could feel himself getting heated as he caressed and squeezed her butt. She leaned forwards to kiss and lick his well toned chest in various places, as well as kissing and sucking on his neck, which was sure to leave marks the next morning. He was slowly losing himself again as the sensations he felt started to build up in his body, faintly reciting her name like a mantra. He started to push back against Tsukuyo's grinding, making her gasp each time and arch her back slightly, which only spurred her on to grind faster. She wanted to feel more of him. It wasn't long before her eyes were shut as she tried to stave off the feeling of releasing herself, leaning forwards as she continued riding his cock like she was on the saddle of a galloping horse. The sight of seeing Tsukuyo slowly losing her mind and her breasts bouncing up and down with great passion gave Ginpachi new energy to thrust harder, making her groan louder and louder with each thrust before she whipped her body up, arching her back significantly as she twitched and wailed in her release, covering his third leg in her fluid. Ginpachi continued thrusting to help her remove the last of the involuntary spasms in her body before she lifted herself off him and collapsed on his body, burying her head in his chest and breathing heavily. Ginpachi was also breathing heavily having withstood his own urge to release, resting his hands on the back of Tsukuyo's head as well as her butt, gently caressing both of them. They could feel each other's heartbeats thumping against their chests.

"You ok for some more?" He asked softly.

"Always..." She breathlessly replied with a smile. Ginpachi grinned in response, happy that they would carry on.

"Alright then, my turn to give some lessons." He strained slightly as he reversed positions, rolling over so that he was on top. Tsukuyo giggled at how swiftly he did it, his strong hands pinning her wrists to the bed.

"Hehe...so forceful." She murmured, more or less drunk on lust at this point.

"Just a special lesson in PE, and we're gonna start with a warm up..." He smirked, moving his head down to draw circles around her breasts and then lines down her stomach with his tongue, all the way to her panties where her core resided. Because she shifted it to sit on him, it was open in full view, still damp from releasing its contents earlier. He was captivated by its beauty, especially the secret that was hidden above it: The pink pearl.

"Ginpach-AHHH...!" She cried out all of a sudden, her hips instantly jerking up from the sensation of his tongue slowing lapping away at her.

That's my clit...! He's licking it...

Tsukuyo desperately squirmed her body as her sensual wailing reached higher volumes with every tongue stroke, gripping the bedsheets incredibly tightly to the point it would probably start tearing. Her hair was starting to cling to her forehead too from the sweat that was seeping out from the intense feeling. Her hormones were in overdrive as she continued to groan in her ecstasy. Each time she felt a long pause in between strokes, she took in as much air as she could before it was abruptly cut short by his tongue prodding, making her gasp even louder than before.

"Oh god-AHHH...Ginpachi..."

His hands firmly held her thighs down as his tongue prodding started to probe the entrance to her wet core whilst his mouth sucked on her clit, making her jerk her hips up erratically as she wailed again, switching from holding the bed sheets to holding his fluffy hair for support. Her wriggling about was a sign she was going to climax. It provoked Ginpachi to press his tongue harder against her folds. Her hips bucked up once more as she let out a piercing gasp followed by another wail, splashing her fluids into Ginpachi's mouth who was taken off guard by her sudden movement. Her back was arched as she spasmed in her climax, even more so when Ginpachi continued lapping away before finally bringing his head up, leaving her heaving for air.

"Earth to Tsuki...you still there?" He chimed merrily, wiping his wet and sticky mouth with his arm. The only response he got was two hands resting on his head and a giddy giggle. He took that as a yes.

"Ok...good. We're still warming up by the way so you're doing pretty good so far." He said before gently probing her entrance with his finger, making her gasp and clench fistfuls of his hair straight away, not letting go whilst he moved his finger in and out. He added two more fingers, pressing up inside her walls to search for her G-spot, and to his delight, found it when her hips involuntarily surged sky high and started moving them in and out. Combined with pressing his thumb against her clit, it quickly shattered whatever sanity she had left as she screamed in her euphoria, sloshing her liquid over his fingers before pulling out.

Ginpachi looked at his soaking hand rather amusingly, almost surprised at how much she was really enjoying it. He slid off her soaked panties down her ankle and dropped it on the floor. When he looked back to her however, she had more or less passed out, her eyes softly closed and her legs splayed out open.

After a few minutes she managed to slowly open her eyes to see Ginpachi sitting there rubbing his wet, sticky fingers before licking them one by one. She looked on rather confused before sighing in disgust and narrowing her eyebrows, remembering what had happened.

"That's gross..."

"No it's not. Someone told me it was hot." He corrected with a grin as he sucked on his finger. She couldn't help but chuckle as he crawled up to Tsukuyo and planted another kiss whilst idly caressing her thigh.

"So...you all warmed up now?" He asked politely.

"Mmhmm..." She nodded her head gently.

"Alright...my own little lesson reserved just for you then." He positioned himself at her entrance, slightly probing it before slowly inching his way inside her. Because of the warm up she had received, she didn't feel any pain. In fact, she was looking rather relaxed as she closed her eyes with a smile on her face and moaned soothingly, whispering to herself about how good his cock felt. Those words with her relaxed tone turned him on as he lazily thrusted forwards to get adjusted to it, scanning her face for any signs of discomfort.

"You ok?"

"Just be quiet and get on with yer lesson will ya...?"

"Heh, you're really asking for it now 'honey'."

"By all means 'darling', go for it..."

With her blessing, Ginpachi slowly increased his tempo as Tsukuyo's legs hooked around his waist. Their pants were growing louder as the minutes went by and Tsukuyo quietly recited his name over and over, her hands roaming his chest. The mantra was interrupted when she felt his mouth latch onto her nipple and sucked on it quite enthusiastically as well as a hand kneading her other breast. She could already feel them harden quite quickly as her eyes were closed tight, trying to not lose herself straight away.

"Gin...to...ki..." She muttered. As hot as her delayed syllable pronunciation was, Ginpachi raised an eyebrow at who's name she was saying and moved his mouth away, instead keeping up the pressure by gently pinching her hard nipples with his fingers as her head squirmed around in pleasure. Still, he was pretty amused by it since Gintoki and Ginpachi were both very similar, if not identical to how they conduct themselves, even if one is from a fictional work and a samurai and the other is also from fiction except he was a teacher. He also started thrusting with more force as her breathes were driven out and her breasts jiggled with each thrust.

"Did I hear that Tsuki? Sounds like you said 'Gintoki'...that's the guy from Gintama. That's not my name now is it?" He teased.

"Hah-hah-hah-Ginpachi..." She whispered with the back of her hand over her mouth. Even though he heard it, he really wanted to make sure if he heard correctly and pinched her harder.

"Eh? I can't hear ya Tsuki, you're gonna have to speak louder." He sadistically asked. Tsukuyo sank her legs deeper around his waist, but she knew they couldn't hold for long as they were starting to shake.

"GINPACHIII...!" She shrieked, opening her eyes from the pressure built up as her legs dropped on the bed. Fortunately for her, Ginpachi noticed this and hooked her legs on his shoulders as they limply waved about, opening her legs up even more and making her even more open to his thrusting. Her back was arching to extreme levels, which provided him with a better angle. Her state of mind was nonexistent as her eyes rolled back with an uncontrolled smile from the pleasure she was receiving, even more so when his thrusting got faster, harder and messier. Her fingernails dug into his shoulders deeply, clinging on for dear life. It wasn't long before she climaxed, screaming as her body clenched and her back arched up once more, spilling herself as she gasped and twitched with each uncontrolled spurt.

Despite that, Ginpachi continued to fuck her with reckless abandon as he repeated her name (correctly too) although he himself was close to the edge. Tsukuyo's gasps waned into breathless, nonsensical babbling as tears slowly streamed down her face. He could only think of one thing. Mine. All mine.

"Shit, can't hold on-Nrghhhh..."

One deep, penetrative thrust later and he spilled himself inside her, his cock twitching as he painted her inner walls in sporadic bursts, making her gasp each time. He lazily thrusted a few more times before coming to a stop, putting his head against her stomach while barely keeping her bent legs on his shoulders still as they both heaved from the pounding he had given. A few minutes went by with nothing but heavy panting before one of their voices broke the silence.

"Want one more... doggy style?"

"One more...and fuck me good...like ya did just now."

"With pleasure."

Ginpachi had a weak smile on his face as he slowly pulled out (making Tsukuyo gasp slightly) whilst she slowly rolled onto her stomach, gathering enough strength in her legs to kneel on all fours. Ginpachi's also knelt down as his hands gravitated to her rear and slowly caressed her smooth, firm butt. He only had one thought on his mind.

Why do you have to be so fucking hot Tsukuyo...?

He made his entrance quite roughly, already making Tsukuyo's knees shake slightly from the exercise they went through earlier before starting off at an intermediate pace, making her yelp loudly. It wasn't long before his hands moved up to knead her breasts and twiddle with her nipples again as he grunted with each thrust. On the other hand, she instinctively massaged her clit to stimulate herself as she babbled his name, groaning long and hard in trills. Her cries of bliss made him thrust deeper and quicker, making her knees buckle as she face-planted against his pillow, a hand holding onto it for dear life while she continued touching herself in the meantime. Ginpachi's hands moved to wrap around her waist to keep her stable. With her ass fully sticking out, his thrusts became faster and messier again. He even slapped her butt several times which made her groan sensually amidst the loud gasping her muffled voice was giving out from the relentless pounding.

Tsukuyo's knees began to quiver violently as he continued to ferociously fuck her, her gasps now fully converted to the sexual groaning her voice was dishing out. Ginpachi on the other hand revelled in the relentless pounding, almost whispering like a devil about how she was all his. He was in complete control, and she loved every second of it. She could barely string together a coherent sentence as he grunted with every thrust, feebly turning her head to face Gintoki.

"Ahhh...Gin...pachiii...I want to-Ahhha...cum..."

"Then cum Tsukuyo. I want to see you cum for me."

Her back arched up as she wailed in her orgasm before flopping back onto the pillow once more, her knees now completely limp as they alongside her waist were fully held up by Ginpachi's arms. To her pleasure (which was the only thing she could feel at this point aside from him moving in and out), he had no intention of stopping as he pounded her for what seemed like an eternity. Tears streamed down her face as she could only muster up weak gasps, her eyes completely rolled back and her hands dropped as she let him dominate her. Ginpachi could feel himself close to bursting as he carried on, squeezing his eyes (and her butt) shut tightly as his voice strained to keep it together.

After three more deep thrusts his entire body clenched as he groaned in his orgasm, sharply spurting his contents all over her inside walls once more in random intervals, loudly slapping her ass each time his cock spurted out more semen as he twitched.

"Nrghhhh-AHHHHH...!"

Surprisingly enough, Tsukuyo also joined him in her own orgasm, drenching his third leg with her own hot fluids, her body twitching every time her pussy released more.

His chest collapsed on her lower back, lazily thrusting forwards out of a lingering desire to carry on (making her moan softly) before grinding to a halt as his heart pounded against her lower back. His hands let go of her cheeks and circled around her waist. He wasn't even bothered to notice the red hand marks from clamping or slapping them so tightly, nor did he want to feel his neck for any hickeys that Tsukuyo planted on him as he rested his eyes temporarily, their breathing still heaving for air. He could feel his cum (and hers) leaking out of her, so his hand drifted to his table for a tissue to stop it from dripping onto his bed.

After a bit of fumbling around he managed to grab a box of tissues and took one, slowly sliding out with a small erotic squelching sound (making Tsukuyo lightly gasp again) as he wiped himself, then her clean (accidentally making her groan again because the feeling of a tissue wiping her soaking wet core somehow turned her on) before tossing it in the bin.

He flopped onto his side whilst still holding her waist as she faced away from him, utterly exhausted from Ginpachi's private PE lesson. His hand slowly ran up and down her fishnet stocking-covered leg, gently squeezing her thigh as he leaned over to tenderly kiss her neck.

She slowly swivelled her head as he was doing so and sealed her lips against his, leisurely taking in each other's tongues once more as their mouths parted wide open. His hand naturally moved up to gently knead her breast again as she comfortably moaned in his mouth. Once they withdrew their mouths, Tsukuyo turned her body to face him and wrapped her arms and legs around him as he responded in kind.

She gently planted more kisses along his jawline and neck whilst he idly ran his hand through her golden blonde hair, simply taking in each other's company without a word for a little while. Ginpachi's eyes felt heavy as he continued brushing her hair. His thoughts briefly drifted back to the bet he made with his class. He'll have to answer it sooner or later. But for now, he just wanted Tsukuyo, and nothing more.

"So...good lesson?" He asked.

"Yeah...good lesson." She replied, giving him another soft kiss as he closed his eyes. She also closed her eyes, calmly caressing his cheek. Unbeknownst to her, he silently inched his head closer and gave his own long, tender kiss, prompting her to bring his head closer so their foreheads rested on each other and nuzzled their noses together.

"I missed you..."

"I missed ya too..."
