  Severus first noticed that something was off with the boy at breakfast in
  the Great Hall. The Gryffindor Trio walked in, that Granger know-it-all and
  the Weasly prat bickering over something. The insufferable whelp known as
  Potter was gingerly walking behind them, casting nervous glances around, as
  if trying to see if people were watching him. He'd made his way to the
  Gryffindor tables and hesitated before he sat, as if he'd expected
  something to happen.

  {Potter's up to something.} Snape thought, as he watched the brat from the
  corner of his eye. Said boy then slowly, ever so carefully, sat down on the
  bench in between his two, still bickering, side-kicks. He winced slightly
  as his backside finally made contact with the wood. It seemed as though his
  friends were looking concerned at him, and he flushed, rattling something
  off. The red-headed menace laughed at whatever the whelp said, and the
  bushy-haired one just looked concerned.

  The dark wizard watched sneakily as the boy fidgeted all through breakfast.
  Brief flashes of pain would cross his face, quickly followed by a flash of
  something the older man couldn't discern. {Maybe someone's given in and
  whipped his backside causing him to learn to stop and think about whatever
  it was he did to deserve it.} Severus mused to himself, a smirk playing
  across his face.

  After breakfast, and a few classes later, Snape had the pleasure of
  watching the young man again during lunch. It appeared as though the boy
  sat down a bit quicker this time, not much though, and wiggled himself into
  a comfortable position, biting his lip. {What in the world was that?}
  Severus thought to himself as he saw the boy shudder involuntarily.
  Throughout the meal, the brat would carry on his conversations as if
  everything was completely normal. Every few minutes or so, he would wiggle
  a bit, and his cheeks would tinge with color.

  By his last class, the 6th years potion's class with Slytherins and
  Gryffindors, the Potter brat had indeed had the potion master's curiosity
  up. He had been one of the first to enter the room, and sat down far in the
  back, slouching his body into his seat before straightening back up and
  wiggling some more. When everyone had filed into the room, he'd ordered
  them to do the potion on the board, as per routine, and to be quiet.

  The dark wizard was pretending to grade another class' essays while
  watching the irritating brat from the corner of his eye again. He noticed
  that when the boy would shift unconsciously, he would also draw in his
  breath, as if something surprising had happened. He stood to begin making
  his rounds and checking on students' cauldrons, saving young Mr. Potter for
  last. When he finally rounded to the impudent teen's workspace, he noticed
  that the boy had shifted so his left leg was under him, and he was leaning
  his weight on it. Although it seemed he should be distracted, the boy
  seemed to be quite concentrated on his potion, so much so that he didn't
  notice when the black-robed Professor loomed behind him.

  As class was dismissed, he called for Potter to stay behind. As the last
  student nearly fled from the classroom, the older man narrowed his eyes at
  the child who had not risen from his seat. Striding over to him, his robes
  billowing behind him, he pulled up a stool and sat across the desk from the
  young man, much as he had done in the boy's first year. "What has you so
  fidgety?" Severus asked, quite bluntly.

  The student blushed a bit, "Nothing Sir. I just had a bit of a rough
  morning... Quidditch practice." Severus looked intently at the young man,
  and inwardly scowled. He had known that was a lie, and knew he would get no
  more from the boy, so he cast a silent cousin of `legilimens' that would
  only allow him to eavesdrop on the child's thoughts, so he could hear what
  the boy was thinking.

  Luckily, this particular spell required no eye contact. Severus stood up
  and paced. "Potter, I do not appreciate being lied to. You did not have
  quidditch practice this morning, the Slytherins had it. What happened?"

  Harry looked dumbfounded for a moment. {Gotta think of something quick, he
  can't find out!} Sucking in a breath, he commented, "I meant my last
  quidditch practice, not that it happened this morning, it is just an injury
  rearing it's head at the moment."

  Snape raised a sardonic eyebrow. "Have you been to see Madame Pomfrey?" He
  inquired.

  {Oh Merlin, no he can't send me to her, she'd strip me and find out!} The
  boy panicked in his mind. "No Sir, it's not that bad, really." He said,
  shifting uncomfortably in natural response before gasping so very slightly
  and closing his eyes a brief second. {Ohhh that felt good. I hope he didn't
  notice that.}

  Severus was quite interested now. He'd known the gasp was of some sort of
  slight shock, but to hear the boy thinking whatever it was felt good, well
  that was just plain... Intriguing. "Mr. Potter, if you indeed have an
  injury, especially one revolving around quidditch, you should report it to
  Madame Pomfrey. She is not a Medi-Witch without a reason." He gave a very
  small smirk. "If you are having trouble sitting, then it will be effecting
  your performance in class, and I will not give you leeway just because your
  backside is a little sore." He said, closing in on the boy.

  {Oh god it is sore, but it's so wonderful.} "It- it's nothing." Harry
  protested. {You'd be fidgeting too if your arse felt this way.} "I just
  need a day to get myself back up to performance." {He smells so good.}

  The man narrowed his eyes, wondering why in the hell the boy was thinking
  things like that. {He is acting like he has a stick up his-} Snape's eyes
  widened in realization, and a slightly malicious smirk played across his
  face. "Mr. Potter, lean back." He ordered as he moved towards the young
  man.

  The young man did so quite hastily to back away from the intruding man
  without really thinking about it, and the feeling of the wooden stool
  pushing his new favorite play-thing further into his arse made him groan
  slightly. {Fuck fuck fuck. There's no way he didn't hear that. God that
  felt fucking wonderful. Uhhhnnn he smells intoxicating. Fuck.}

  Something in Snape's eyes gleamed as his smirk widened into something else
  that was downright scary. "I believe yesterday that you earned a detention
  with me, and I informed you I would call upon you when I freed up my
  schedule. I think that now is quite an opportune time to enforce that."

  {Ohhh yes. Oh no!} Harry's eyes widened a bit. "P-professor?"

  "You will be cleaning the large cauldrons for the next hour, starting now.
  No magic." Severus ordered. He'd chosen the task as it would have the boy
  bending over and moving around the most.

  "Y-yes Sir." Harry stated, going to the closet that held the cleaning
  supplies, stored there just for detentions. {Oh Merlin, the large
  cauldrons? I can't lift those, I'll have to bend over. Maybe I can keep my
  robe on and he wont say anything about it possibly getting dirty.}

  "Oh, and remove your robe. We don't need it to get dirty." Severus said,
  the evil smirk never leaving his face.

  {FUCK!} The boy stilled. "I'm sure that's not necessary." He tried to
  protest.

  "I'm sure it is. It would be ill-received if I were to have you clean such
  a mess in your school attire. The other Professors wouldn't approve in the
  least." Snape retorted.

  {Oh god, I hope it's far enough in the tail doesn't poke through my pants.}
  The younger man shed his outer robe and began to work, trying to keep his
  bum as pointed downward as he could.

  {Tail? He has a tail toy? I wonder how long it is...} Severus thought to
  himself. Gliding effortlessly towards the boy, he saw the brat's shoulders
  tense a bit.

  {Ohhh he's torturing me. No, he's coming closer! Shit! Gotta move!} Harry
 shifted around, his arse facing away from the man. The sudden movement       
  caused his pants to tighten, which caused the tail of his play-thing to
  impale him deeper and he groaned, closing his eyes, and gripping the side
  of the cauldron. The half-hardness he had been trying to hide all day had
  grown into a full blown erection at this point. {Oh god, fuck that felt
  good. Clean Harry, clean, get this over with so you can go have a proper
  wank.}

  Snape's eyebrows shot into his forehead, and he decided to see if he could
  have a little fun. "I must check on a potion I am brewing in my private
  labs. It is in it's final stages, and I need to be stirring it continuously
  for 25 minutes. When I come back, I expect this cauldron to be spotless and
  you to be started on the other." He said, billowing out of the room and
  slamming the door behind him. Instead of walking away, he leaned himself
  against the door and listened to the boy's thoughts.

  {Oh, 25 minutes! I can get a wank in during that time and still clean the
  cauldron... Ohhh yes... His smell... His hands, those long fingers oh
  Merlin... That scent is enough to drive anyone mad...} He gasped a bit
  audibly, then moaned. {Oh god, feels so good, this tail makes a perfect
  grip... I wonder if he even likes guys... God his skin is so pale, it's
  beautiful, and the scars look delicious... Ohhhhhh I can't stand this,
  ungh, deeper, oh my god! Fuck! Yes! SEVERUS!} A rather loud moan and the
  clatter of something falling to the ground sounded out.

  Snape took this cue to both cut off the legilimens cousin spell and return
  to the room, some 17 minutes early. As he opened the door, he proclaimed,
  "It seems my potion had been tampered with." He stopped to take in the
  sight of a furiously blushing Potter who had cum all over his own hand, his
  stomach, the cauldron, and a bit on the floor. His pants were down around
  his knees, his boxers close behind, and his shirt-tail pulled upward. The
  boy had apparently used the cauldron as support while he penetrated himself
  with the 7 inch long, smooth sex-toy that held a bunny tail on the end of
  it which was supposed to protrude from the arse to make make everyday
  things like sitting and walking penetrate him deeper.

  All Harry could say was, "Fuck."

  The smirk deepened once again on the potion professors mouth. "No Mr.
  Potter, that's called masturbation. I'm afraid fucking requires two or more
  parties present. Do you need a practical demonstration?" He raised an
  eyebrow.

  The thought of this had Harry becoming half hard again, and his eyes
  widened a bit. "What?"

  Severus walked to the boy, who was still a bit too afraid to move, and
  loomed over him. Bending down to look into the teen's face, he flashed an
  evil smile. "I asked if you wanted a practical demonstration of fucking Mr.
  Potter." He said in a low, seductive voice that almost sounded like
  purring. Noticing the young man had become quite aroused, and now sported
  another raging erection, he added, "It seems at lease one of your heads had
  been paying attention."

  Harry mumbled something and averted his eyes quickly. "What was that, I
  couldn't hear you." Severus stated.

  "I said, `yes I want a demonstration'." Harry answered shakily, feeling
  quite foolish, sure that the man would throw him out and berate him at any
  moment. Instead, when the feeling of a warm hand came to his stomach in the
  mess he'd already made wiping at it, he looked up to see his snarky potions
  teacher pop a cum-covered finger into his mouth, close his eyes, and make
  an approving noise.

  Still having the young man's seed covering his hand, Severus opened his
  eyes, and within a flash of movement had the boy's cock wrapped in those
  long fingers, using the previous activity's remains as lubricant. He snaked
  his other hand down and grasped the furry end of the bunny-tail toy, and
  slowly slid it outwards, then plunged it back in sending the young man
  before him into a state of bliss. This continued for a few minutes until
  Severus got tired of waiting, pulled the tail toy out, and his own erection
  played hard against his zip.

  He stood, lifting the boy with him as he made his way over to his desk,
  where that elegant hand with long slender fingers swiped at the half graded
  papers and other small things covering the desk's surface. Setting the
  young man down on the edge of the desk, Severus bent slightly as his mouth
  found it's way to the unmarred neck before him, sending a trail of kisses
  around it. Simultaneously, he'd again coated his fingers in the earlier
  activity's evidence, and trailed the tips to the brat's arse, cupping and
  spreading the boy's cheeks while his other hand un-butted his trousers and
  pulled the zip downward, releasing the erection.

  When Harry looked down at the cock that had sprung free from his
  Professor's clothing, his eyes widened. Severus smirked at the young man,
  and coated his penis with the younger man's cum to act as a lubricant.
  Slowly, he eased the boy on to his throbbing cock, and bit down on the
  young man's shoulder as his head pushed past the ring of muscles that
  clenched tightly around himself.

  Harry let out a moan, throwing his hand up and grasping his teacher's hair.
  The man started a pace, slow and steady, and as the arse around his cock
  relaxed some, his thrusts became more penetrating.

  "Oh fuck." Harry moaned. "God that's... It's full." He began thrusting back
  against his potions professor, then used his hand tangled in hair to his
  advantage, pulling the dark wizard's head towards his, and capturing his
  lips in a needy kiss. "Harder." he whispered, his breath ghosting over the
  older man's lips.

  Severus was only too happy to comply. Pounding into the young man before
  him, he reached a hand out and started stroking the penis that looked so
  inviting. "More." Harry whispered as he bucked and arched his back like a
  cat after a mid-day nap. After a few attempts, the young man finally
  managed to pant out, "If I'm dreaming I don't ever want to wake up."

  This admission sent Severus into a frenzy, losing his pace and just
  thrusting and pounding into the young man's arse, licking and biting at the
  skin that happened to be closest to his mouth. Still stroking, grasping,
  squeezing, and toying with the penis in his hand, he felt the muscles of
  Harry's arse clench around him. "Fuck fuck FUCK SEVERUS!" The boy screamed,
  wrapping his arm tightly around the man's head as he climaxed yet again,
  sending his hot, sticky stream shooting onto both of their clothes.

  The sight and sensation around his cock made Severus fall over the edge as
  well, groaning, "Hnnn, Harry" as he came hot spurts into the young man's
  cavity. After another long kiss, they pulled apart, and Harry started to
  whisper a cleaning spell but the older man stopped him. "I want you to
  remember this." He said, picking up the bunny tail toy and banishing the
  mess that resided on Harry's outer person. "You will wear this the rest of
  the day today, you may not clean yourself out until tomorrow morning, then
  you will continue to wear the tail all day before coming to serve another
  detention for your inappropriate language during today's detention."

  Harry's eyes grew wide and he complied most readily, happy at the chance to
  have a repeat of today's performance. Slipping the tail toy inside of him
  to stop any of his Professor's cum from leaking out, he pulled his trousers
  on and fixed his clothing a bit. "See you tomorrow." Harry said as he
  turned to leave.

  "Two more things." The silky voiced called to him. "One, there will be no
  self release between now and then. Two," He pulled out his wand, casting a
  silent spell as the motions of the tail, pulling it out then pushing it
  back in a few times, caused the boy's knees to shake a bit and a moan to
  escape his lips. "I expect you will know better than to make those
  delightful noises and movements when I choose to do this at any given
  time." He smirked.

  Harry's eyes widened again as he realized that at any time should he make
  those sounds when the older man decided to play with him, his classmates
  and possibly other professors, would have their attention on him. "Y-yes
  Sir."

  "Good." Severus stated, and with a flick of his wand sent the tail further
  into the boy, relishing in the sight of the young man shivering trying to
  compose himself at the deeper penetration. "Dismissed." He said, billowing
  away, banishing any remains of what had happened from the room.
