****** Lessons In Sexuality ******
by VampireHydeFTW
Summary
     Knowing his parents wouldn't be able to help him answer his sexual
     questions, Yuuki resorts to seeking out the advice of his favourite
     teacher.
            There were two normal reactions to a lesson on sexual education,
complete and utter humiliation, or to treat it like one big joke all the while
being secretly fascinated. That was how Yuuki had felt back then, he remembered
it clearly even now a few years had passed and he had matured. The only thing
was, it was all well and good learning about human reproduction, safe sex and
the variety of diseases you could catch if you ignored your teachers and
parents but it didn't help Yuuki with his worries that had only been made worse
by his online research. Knowing his parents would be no help, he had remembered
how open and honest his science teacher had been when giving these lessons, and
how approachable. He always had been Közi's favourite student and more
importantly, he knew the teacher preferred the presence of men to women, which
was exactly why he was here.
            “Yuuki?” Közi asked, surprised when the pink haired boy entered the
science lab where he was busy straightening things out from the last lesson,
his white lab coat hanging open revealing the red t-shirt and black trousers he
wore beneath. “Is something bothering you?”
            “Kind of,” Yuuki confessed, taking a seat on one of the stools as
he nervously twirled a strand of hair around one finger. “I, well that is to
say, what's it like to have sex with a man?” There it was, spoken out loud at
long last. He forced himself to keep eye contact with his teacher, sex was
natural, that was what Közi had tried so hard to teach his students, nothing to
be ashamed of, just a normal urge.
            “I see,” Közi said with a knowing smile, “It's a matter of taste
really, everyone enjoys different things.”
            “I know,” Yuuki said growing frustrated. “What I mean is, how can
it be pleasurable to, well you know?”
            “To have anal intercourse?” Közi asked. “If it's a question of
size, well that's not really a problem, a penis actual fits rather perfectly.”
            “But is there pleasure? For the one underneath I mean.” Yuuki said,
blushing. Something about the way Közi was looking at him right now sent
shivers down his spine, he always did have a crush on his teacher and often he
suspected his feelings were returned.
            “Well yes,” Közi replied. “Emotional pleasure, obviously, but
physical too. There's a bundle of nerves deep inside a man, his prostrate, the
sensations against these nerves can bring intense pleasure. Did you know it was
possible to ejaculate from just massaging these nerves?”
            “Well that's good to know.” Yuuki replied, relieved to hear this.
            “If you're really interested, you could try pleasuring your own,”
Közi suggested. “You're too young to buy toys but I don't mind helping you.”
            “What, by pleasuring me yourself?” Yuuki asked surprised,
misunderstanding what his teacher meant.
            “I meant buying you some toys,” Közi corrected. “Unless, do you
want me to help you?”
            “You can't, you're my teacher.” Yuuki said, his cheeks quickly
reddening to match his pink hair.
            “That's not a question of desire though, is it?” Közi asked, moving
around his desk and resting his hand on the top of Yuuki's lap. “Desire doesn't
listen to rules.”
            “Please, don't make me say it,” Yuuki complained, just as his
teacher’s lips met his own. Startled he pulled back and would have fallen from
his seat had Közi not been there to catch him. “You're my teacher!”
            “I am,” Közi agreed, with the sense to back off. If he wanted,
Yuuki knew, he could get Közi in major trouble for that kiss, probably fired.
The same thoughts were racing though Közi's mind. “I'm sorry. You're right, I
shouldn't have.”
            “I enjoyed it,” Yuuki confessed, then blushing even redder. “I've
dreamed of kissing you, and more.”
            “I'm an adult, I should know better. You're just a child.” Közi
scolded himself.
            “I'm seventeen, I know what I'm doing,” Yuuki argued, the last
person he wanted to see him as a child was Közi. “Please, if it's what we both
want, help me learn?”
            “Not here.” Közi decided, hurrying to his desk and grabbing a set
of car keys. “Anyone could see.”
 
            Közi's apartment wasn't too far from the school but it was long
enough for Yuuki to think about what he was doing. He did want this, his body
was aching for Közi's, but that didn't mean it was the right thing to do. He
distracted himself with small talk, staring out of the car window as he tried
his best to calm down. Once inside the apartment, where he was greeted by a
ginger cat, Yuuki followed Közi into his kitchen managing to avoid eye contact
the whole time. He was far too embarrassed to look at Közi.
            “I don't know what I'm doing.” Yuuki confessed, making Közi laugh.
            “That's why I'm the teacher.” He said, kissing Yuuki again with a
lot less hesitation than he had done back at school. Melting against his
teacher Yuuki worried about his technique, though if Közi cared he didn't let
on.
            “Now, to find your prostrate,” Közi announced. “Strip and lie down
on the table.”
            “OK,” Yuuki whispered, as his teacher left the room to fetch some
supplies. He was beyond terrified but he did as requested, wanting to hide his
body from his teacher’s prying eyes but resisting the temptation. He was glad
he hadn't just for the look of desire he saw on his teachers face as he
returned.
            “You're stunning,” Közi confessed, as he pulled a latex glove over
his right hand and coating it with lube. “But you do need to spread those
pretty legs of yours.”
            “Sorry,” Yuuki whispered, whimpering as a damp finger ran over his
now exposed entrance. Was this the emotional pleasure Közi had mentioned? The
enjoyment of knowing just how much another man wanted to be inside you? It was
nothing like the porn he has watched, but that was a good thing because he
didn't want to feel used, like he had felt many of these men were.
            “Preparing a man can be an essential part,” Közi explained, as a
single finger slid over the tight ring of muscles, pushing slowly and deeply
into his eager student’s body. “How does it feel?”
            “Good,” Yuuki admitted, his embarrassment only growing stronger
despite this.
            “Your prostrate should be around here.” Közi advised, laughing as
Yuuki let out a loud moan of pleasure.
            “Oh god, that was,” Yuuki tried to explain, just as the finger
brushed against him again. Was this really what anal sex felt like? It was
wonderful and scary all at the same time. To lose control to the pleasure like
this, he didn't think it could be possible.
            “You're enjoying this.” Közi needlessly commented, as he watched
his student on the table, so innocent that he couldn't disguise even the
tiniest part of his pleasure. He always had known Yuuki would be beautiful
naked and aroused, yet reality was even better than the fantasy had predicted.
“Now for a second finger?”
            “Please,” Yuuki begged, as a second finger brushed beside the
first. He could feel some pressure now, but that was delightful to, so he shut
his eyes and allowed himself to feel, feeling like he might just die in
embarrassment and that it was a perfectly fine way to go. Permission wasn't
asked for the third finger, but by then Yuuki wouldn't have known what to say,
he hardly knew what he wanted, except to jerk off his aroused length. He didn't
touch though, partly by embarrassment but also curiosity, could he cum without
touching himself? Before it had hardly seemed possible, but that was before.
            He lost track of time as Közi fingers teased him, he had no idea
how long he had been lying on this table moaning in the pleasure that seemed to
build up inside him. He knew he was approaching orgasm and his fingers twitched
with the need to finish himself off quickly but he didn't dare let Közi down.
So he lay there, enjoying the lesson as it was intended, until with a shudder
his orgasm hit like nothing he had ever felt before.
            With a smirk Közi withdrew his fingers and threw away the glove,
leaving Yuuki to recover from his pleasure. His own arousal ached to be touched
but it felt cheap to masturbate in front of his student. This wasn't about his
pleasure, so he ignored his needs and picked up a glass dildo.
            “Here's your homework.” Közi said, as he handed it over to his
smiling student.
            “Sensei,” Yuuki said finally making eye contact. “Thanks for the
lesson.”
            “I have so much more I can teach you,” Közi said with a smile.
“Blow job techniques, penetration, a whole variety of toys, bondage and, well I
won't scare you.”
            “S&M,” Yuuki finished, his eyes widening in surprise but he was
smiling. “It all sounds delightful. All of it.”
            “But these lessons, you realise how important they are that they're
secret?” Közi asked.
            “I know,” Yuuki reassured him. “Nobody will ever know.”
 
            That night Yuuki lay in his room, Közi's gift buried deep inside
him, as he leant against a mound of pillows unable to resist the chance to
return to his afternoon pleasure. This wasn't the same though, it meant so much
more to have Közi with him but that didn't mean he wasn't enjoying himself.
            With a, hopefully, sexy smile he picked up his phone and aimed it
at the mirror, taking a photo that he quickly sent to his teacher before he
could worry about the consequences, getting a response seconds later. He stared
at the image on his phone with wide eyed fear and anticipation, a hint at a
lesson to come? It was forgotten as a second image of his teachers naked body
appeared on his phone. Közi was beautiful and so sexy that he couldn't help but
pleasure himself while staring at it. He let himself cum and took a picture of
the mess, sending this to Közi with the message This is what you do to me.They
were playing with fire now but Yuuki couldn't think of anything more exciting
than testing his own limits, only just beginning to learn that he had none.
