Sinful Sensei-Part 2

"Mom, I'm going to Gokudera-kun's house to study, I might spend the night!" Tsuna called to his mother as he pulled on his jacket, taking his schoolbag with him to further support his alibi.

"All right Tsu-kun, be home in time for dinner tomorrow!" Nana called to him from the kitchen. "Have a nice time!"

You can count on that...

"I will, Mom!" Tsuna said and took the keys to the car his father had bought for him for his 16th birthday. How he was able to afford a simple Toyota Echo on his salary as some kind of a Miner or Gold Digger, he didn't know.

Looking over the directions written on the piece of notebook paper, Tsuna carefully studied the neat handwriting as he got into his car and started it up. He snorted lightly and blushed at the little message at the bottom.

I'll be waiting for you, sweet little Tsunayoshi-kun.

And with a little heart no less. Cute.

Shaking his head, Tsuna backed the car out of the driveway, pulling into the street and driving off into town. Looking at the clock radio, it was 7:15. According to the directions, it was a half an hour tops to get to where the directions indicated.

Apprently, it was a little cottage out near Lake Namimori, in the more rural areas. Seemed appropriate, no?

Driving off the main road, Tsuna drove out into the interstate road leading out to the countryside.

--

By around 7:55, Tsuna pulled up to a small cottage that wasn't too far from the lake. It was pretty quiet out, the only sound being the occasional cry of a loon.

A few lights were on inside the cottage, Mukuro was sitting out on the front porch, reading a book under the glow of the bug zapper light. He looked up as Tsuna's car pulled up and smirked lightly, setting down the book as he stood and went over to greet him as the student parked the car and got out.

"Right on time, Tsunayoshi, I suppose I should've expected it. Kufufu..." Mukuro chuckled, averting his gaze to the car. "Mm, nice car."

"Th-thanks...my dad got it for me..." Tsuna said softly, blushing a bit.

"Oya? Well aren't you spoiled." Mukuro teased, reaching over to ruffle his hair.

Blushing on the contact, Tsuna shook his head. "No, I'm not spoiled at all. I don't really ask my parents for much either...and my dad is away on business a lot of the time."

"Ah," An indescribable look came into Mukuro's eyes as his pulled his hand away from the smaller boy, nodding in understandment. "Well then, shall we go inside?"

"Uh...s-sure..." Tsuna's face became even pinker.

"Kufufu...you're quite cute when you blush Tsunayoshi-kun. Do you know that?" Mukuro chuckled lightly, taking hold of Tsuna's hand as he led him up the front steps and inside the cottage.

The inside looked very cozy and homey. A living room area with a couch, futon, and recliner, a TV, a bookshelf containing books and DVD's and VHS tapes. A kitchen, dining area, a door leading to a bathroom, and three bedrooms.

"Wow...it's very...nice..." Tsuna murmured, his big chestnut eyes scanning about the place.

"Isn't it? My father had it built a couple of years after Nagi and I were born, and we usually come here for some days during the summer, and even on weekends or during long holidays." Mukuro said softly, squeezing the smaller boy's hand a bit tighter.

"Is your father still alive?" Tsuna asked.

The blue-haired teacher shook his head. "No, he died a couple of years ago from a heart attack. He had pretty frail health, but he ketp himself in good shape and was great to Nagi and myself. Our mother died in an accident when we were nine, and so my father worked hard to take care of us. As a result he neglected himself a lot of the time, and so then it happened. Luckily both Nagi and I were moved out and had finished college at the time, so we weren't left completely alone and had to be sent off to a foster family."

"Oh..." Tsuna looked up at his teacher sympathetically. "I'm sorry that happened." He said genuinely.

"Don't feel sorry, Tsunayoshi." Mukuro looked down at him with half a smile. "I'm not dwelling on the past, nor am I letting it get in the way of living my life. I look back at my father for the days he lived."

Tsuna smiled and kissed his cheek. "That's good."

"On the other hand," Mukuro turned and held Tsuna to him, looking down at him with lust-filled eyes. "I did not have you come here to discuss my past life...but to..." He lowered his hand down to the smaller boy's crotch, massaging through his pants. "...Enjoy you."

"Uhn!!" Tsuna let out a squeak/grunt at the contact, his eyes widening.

"Kufufu...you liked that, didn't you?" Mukuro smirked, his hand applying more pressure.

"M-Mukuro-sensei!" Tsuna moaned, his cheeks pinkening as his stomach coiled in pleasure and excitement. "Aaah!!"

"So cute." Mukuro pulled his hand away, snickering at the whine of protest and he lifted the smaller boy into his arms, carrying him off to one of the bedrooms.

Tsuna's breathing was slowing as he was carried away, bridal style he might add, into one of the rooms. He looked up at his teacher with his big, chestnut eyes that just oozed of innocence.

So...innocent... Mukuro thought, smiling lightly at the brunet. There was something about his innocence and pureness that just seemed to make his heart flutter. It didn't help that he was incredibly adorable too. He must be a virgin too...kufufu...well that's nice to know. Believe it or not, he himself was also a virgin.

All his life, he was taught by his father to always treat his partner with love and respect, since those were part of the keys to maintaining a good relationship. His father didn't believe in the whole "No sex until the wedding", but simply put it as "Whenever you and your partner are really ready".

Since having Tsuna as a student, he surpassed all of his expectations in what he was looking for in a partner...and yet failed in class. Despite that, he was truly irresistible and had such a kind heart, putting everyone else before him and always giving off such a welcoming feeling to anyone who was nice to him. Around school he was known as "No-Good Tsuna" since he was so clumsy and failed at his grades, but they failed to see just how amazing the boy really was.

And Mukuro didn't want to be one of those people. No way. Tsuna was just too much for him to pass up.

Coming into the bedroom, he gently lay the small boy on the bed and crawled on top of him before returning his lips to the other's.

Tsuna felt a shiver go up his spine as he anticipated what was going to happen, kissing back as he brought his arms securely around the older man's neck. He squeaked lightly as he felt his hand lightly stroke along his side, creating stimulation.

"Mm-mm!" Tsuna uttered between kisses.

Chuckling between their mouths, Mukuro slowly slipped a hand up his shirt, gently caressing the soft skin underneath his fingertips. The other's skin was so light and looked soft to the touch, and he was right. He relished the sweet taste Tsuna had in his mouth, it was so sweet...it was better than chocolate. And that was big in itself for something to be better than chocolate.

Pulling back, Mukuro looked down at the smaller boy, smiling softly as he chuckled at the sight of him. His cheeks were bright pink, his eyes lightly glazed and unfocused, yet shining, and pink peach lips lightly parted. He was truly a sight to behold.

Bringing his hand up from under his shirt, he gently caressed Tsuna's cheeks as he gazed at him lovingly. He didn't say anything, he just looked at him, touching his soft cheek.

Tsuna looked back up into his teacher's mismatched eyes, bringing his hand up over his, smiling in return. He didn't know how this happened, but he didn't want it to end.

After a few moments, Mukuro leaned down, touching his forehead to Tsuna's, smirking lightly. "Are you ready for more, Tsunayoshi-kun?"

"Y-yes..." Tsuna uttered. "Please..."

"Kufufu...as you wish then." Mukuro rose back up, lifting off Tsuna's sweater and putting it aside. He then dipped his head and kissed along the soft crevice of his neck.

"A-aah..." Tsuna moaned lightly as he found himself loving the unknown yet desirable contact, wanting so much more. He squeaked lightly as Mukuro bit down on his neck, but not enough to hurt him or make him bleed.

Smirking some more against his neck, Mukuro nibbled along Tsuna's neck and shoulder junction, leaving a small hickey. He ran his hands down the smaller boy's sides until they reached his pants. Carefully he unzipped the zipper of his khaki slacks, proceeding to pull them down.

Moaning softly, Tsuna looked up at his teacher as he arched his body to assists in removing his pants. Staring with disapproval at his still-dressed state, he reached over and took hold of the older man's shirt, earning a look of surprise but then lifting his limbs to allow Tsuna to pull off his shirt, tossing it aside.

"Kufufu...in a hurry are we?" Mukuro teased, pulling off Tsuna's pants completely and putting them aside with their shirts.

"Ah...um..." Tsuna blushed even more, not sure how to respond, especially now that he was naked except for his boxers.

Mukuro snickered, eyeing his boxers and then looking down back at Tsuna. "So innocent..." He leaned down to kiss Tsuna once more, his hand wandering down his boxers, grasping his half-assed erection.

"Mmmmm!!" Tsuna gasped in their mouths as rush of blood coursed through his body and down to his region, bucking his hips in response.

Pleased with his reaction, Mukuro lightly pumped the smaller boy's length, pulling back to watch his reactions to his ministrations.

"A-aahh!! M-Mukuro-sensei!!" Tsuna cried, his hands grabbing at the covers, clutching them tightly for leverage.

"Kufufu...no need for the suffix...we're not in class right now, Tsunayoshi-kun..." Mukuro murmured in amusement, his hand pumping the smaller boy a lot faster.

"Kyaaaaah!! Aaaahhh!!" Tsuna squealed, his eyes squeezing shut as loud moans ripped through him. The pleasure was becoming so intense that it was so hard to sit still without feeling like he was about to burst.

The beautiful sounds that his student was making was definitely taking a toll on his own hard-on, and he could sense the other's oncoming climax as pre-cum was already leaking out.

Tsuna felt the pleasure built up and it ripped through him line a tsunami, his eyes shooting open as a loud moan of pleasure escaped him. "M-Mukuro!!"

Mukuro chuckled lightly, his hard-on twitching even more at the sweet sound of hearing his little love speaking out his name in the way only he could. He pulled his hand away, licking the sticky substance off his fingers, looking down at the smaller boy as he panted hard, his eyes all hazed and unfocused.

"You're quite sensitive, Tsunayoshi-kun...my my." Mukuro remarked.

Blushing a bit, Tsuna looked away. "Eh...well...I'm...not very...e-experienced..."

"Kufufu...I didn't expect you to be, that's quite all right. As am I."

Looking up at his teacher in surprise, Tsuna didn't expect to hear that.

"...A-are you a...?"

"Yes, Tsunayoshi-kun. I am."

"...Wow."

"Kufufu...didn't expect that, did you?"

"Well...no..."

Mukuro shook his head, chuckling as he pulled down his pants, revealing to be wearing dark blue boxers printed with pineapples. Tsuna looked at the boxers with curiosity and amusement, giggling. Looks like the rumours of him wearing pineapple-printed underwear were true.

"They were on sale." Mukuro's cheeks turned a light shade of pink in light embarrassment. "It's not what you think."

"Don't worry, I won't tell anyone." Tsuna promised. "I like them though."

"...Thank you," Mukuro looked away, blushing a bit.

Tsuna smiled and sat up a bit, kissing his teacher's cheek. The blue-haired man chuckled and turned his attention back to his student. He brought two fingers to his mouth.

"...Eh?" Tsuna looked at him in confusion.

"Coat them with your saliva as best as you can, trust me, it'll make things easier...and more pleasuring for you, Tsunayoshi-kun." Mukuro told him.

"O-okay." Tsuna took his hand and suckled on his fingers, coating them with his saliva. He didn't understand why, but just decided to roll with it.

Once they were coated enough, Mukuro carefully brought his fingers down to his entrance, until Tsuna squealed,

"What are you doing!?"

"Stretching your inner muscles." Mukuro explained, a bit puzzled yet amused. "What's the matter?"

"W-why? Why down...there?"

"Silly, do you not know how men have sex?"

"Eh...well...n-no..." Tsuna admitted.

"Kufufu...well then, allow me to show you." Mukuro smirked lightly, inserting a finger into Tsuna's entrance.

"Uuunnngghhnnn!!" Tsuna grunted/groaned in pain at the intrusion. Mukuro understood and kissed him deeply to distract him, carefully and gently forging his finger inside him. He was so thight, so warm...he could barely wait to feel his own member engorged in that orifice.

Cringing at the light pain, Tsuna managed to get himself distracted and used to the finger inside of him. Once relaxed, Mukuro inserted a second finger, moving them in the scissoring motion to stretch his inner muscles, all the while searching for a certain spot...

"Aaaahh!!" Tsuna squealed in pleasure as he felt Mukuro's fingers brush against a spot that brought back the waves of pleasure through him. He had no idea such a spot was located inside of him. The sweet pleasure was causing his member to pitch a tent in his boxers again.

Found it. Mukuro chuckled, playing around with the spot for a few moments before pulling his fingers out, earning a whine of distress from the loss of contact from the smaller boy beneath him. He pulled off his boxers and then his own, freeing his hardened member. Tsuna looked at his teacher with excitement and anticipation as he lay back on the bed, spreading his legs as he waited to see what he was going to do next.

"Are you sure, Tsunayoshi-kun?" Mukuro questioned him as he positioned himself at his entrance. He was not about to violate his student if he didn't want it. No way.

Nodding, Tsuna took hold of his shoulders, bracing himself for the pain. "Yes...I want you to...love me, Mukuro...sensei..."

With a smile and light nod, Mukuro carefully entered him, gently so he wouldn't hurt him. Tsuna cringed and hissed loudly in pain as something far larger than fingers entered inside of him, causing his inner muscles to clench.

He's so tight... Mukuro thought, fighting back the urge to fuck his student into the mattress right then and there. He settled inside of him, kissing him deeply as a way to distract him and apologize. After a few moments, he received a soft moan of encouragement and then slowly pulled out of him part of the way, going back in as he worked to gain a steady pace in thrusting.

"Aaah...aah...M-Mukuro...yes...yes...!!" Tsuna uttered, moaning loudly as the pain was abruptly replaced by red-hot pleasure. "F-faster!" It felt so good right now, he wanted so much more.

"Ngh..." Mukuro obliged and started to thrust in and out of him a lot faster than before, making sure that his member brushed against the other boy's prostate gland to add stimulation.

Tsuna moaned his teacher's name over and over as his moans ripped out from him, his legs shooting up to wrap around the taller man's waist. He dug his fingernails into his shoulders as the pleasure continued to build up within him, his stomach coiling with excitement. It was so much more intense than having received a handjob, he found himself crying out louder.

"T-Tsunayoshi..." Mukuro moaned out, holding his student to him as he thrusted into him a lot faster, relishing the exhilaration of their intimate activity. He thrusted even faster into him as he earned sweet moans and cries from the smaller boy. With a free hand, Mukuro took hold of Tsuna's neglected length, pumping it along with his thrusts.

It wasn't long before Tsuna could feel himself coming to his climax at the added stimulation, the intensity and pleasure building up inside him that it was almost too much for him to handle. One last thrust and pump soon sent him into a violent climax, screaming out his teacher's name as he came all over their stomachs.

Hearing his student scream out his name like that was the final straw that broke the camel's back, sending Mukuro over the edge as he let out long drawn-out groan, uttering Tsuna's name as he spilled his seed inside of him. He hunched over, panting hard as he tried to regain his breathing, still sheathed inside of him. After a few moments, he pulled out of his student and kissed him deeply before rolling off to the side.

Panting, Tsuna looked over at his teacher and scooted over to him, snuggling into him. "M-Mukuro...sensei?"

"Mm?" Mukuro looked over at Tsuna, bringing his arms around him and cuddling him closer.

"What are we going to do about...?" His voice trailed off.

"Kufufu...don't worry, I can keep a secret. We simply won't tell." Mukuro assured.

"O-okay..." Tsuna felt a bit relived. He snuggled into the blue-haired teacher's chest, sighing happily. "I love you Mukuro-sensei..." Was all he could muster before falling asleep.

Taken aback by the sweet confession, Mukuro smiled and held him tighter, his eyes drifting closed.

"I love you too, Tsunayoshi-kun..."

The two of them soon fell asleep, now not only teacher and student, but lovers.

How was it guys? Satisfying for a part 2? X3
