(This one is called Changes and it starts with Harry getting the talk to Hermione and Ron doing what they talk about ;) -Kellynxx)

Harry was laying on a couch in the common room, reading his Charms book. His eyes flickered to the fire which was blazing. He gave a yelp- for Sirius's head had just appeared in the fire. He threw himself onto the rug by the fire. "Sirius! Do you have advice for the next task? What's wrong?" Harry asked, quickly.
Sirius looked embarrassed. "Well..erm I was given instrusctions from Remus..seems to think you're ready..well, here goes. Do you know what it means if you sleep with someone?"
Harry felt his cheek grow rosy. He had. "Err..yeah." He realized where this was going and he didn't like it.
"Good. I was dreading having to tell you what goes where." Sirius sighed. "But there are other things. As your Godfather, I ask you to answer me honestly. How far have you gone?"
"Err..I..well..haven't even kissed anyone." Harry mumbled shyly.
"Then I'm not to late. Step 1. Don't bite. Lick, kiss, nibbled but not bite. Step 2. Don't grab her breasts- wait- please tell me you're interested in girls-" Harry nodded angrily. "Good. Remember to only go north if you have direct permission."
Harry blushed furiously. "Right."
"Step 3. Hands on her waist. Waist. If she likes that, you can maybe go down and only down to her hips. Not farther. And don't make the same mistake ole' Billy Rungard made."
"What did Billy do?"
"Went straight for the chest," Sirius sadly shook his head. "Little Sarah Adams broke 3 of his fingers, then he tried to fix them and instead Transfigured his hand into a hoof. Enough about Billy. Now, listen up, STDs. Sexually Transmitted Diseases. Very nasty, very embarrassing. I can't force you not to sleep with anyone, but at least use protection. Always wear condoms and make sure the girl is on Birth Control unless of course you're married and trying for a kid. Trust me, you do not want a kid at this age and I'd be particularly ashamed if my Godson's girlfriend or one-night-stand had to have an abortion. And promise me, promise me that you will wait until you are 15. Promise?"
"Promise. Erm..I was actually planning to wait until marriage.."
"So was James." Sirius winked massively and putting emphasis on "was".
"Wha-? You mean they..? When they were..? Oh God.."
"Yeah, spent the weekends with her in the Room of Requirement. Every freakin' week." He laughed.
Harry frowned. "That's just..they weren't married!" He burst out.
"Try not to judge them too harshly. They were hormone-induced teens. Cut them some slack. And besides, I'm sure a fair deal of your friend'll have had sex before the age of 17. Now, don't feel to bad if it hurts the girl first time- it always does-and don't expect oral-" Sirius said. "Damn, I think I hear someone coming!" Sirius promptly vanished. Harry's face felt very warm in the chilly Common Room as he threw himself back onto the sofa, not keen on entering the dorms lest he had to explain to Ron what he had just experienced. Just as he almost drifted off into well-earned sleep, a small creak of a door interrupted him. His bushy-haired friend was walking cautiously down the stairs wearing a fluffy white robe and slippers.
"Hi, Harry." She said softly, approaching him.
"What made you come down?" He asked, hoping she hadn't heard the mortifying conversation before.
"Oh. Well. I was going to get my medicine for..er..stomach aches. I left it down here." Hermione shyly crossed the room and picked up her bookbag from the couch. "Muggle medicine." Hermione informed him, digging out a packet of tablets and popped one out.
"Were you talking to Sirius? How come you didn't tell me?" asked Hermione as she sat down on the couch and swallowed the pill. Harry felt his cheeks redden.
"Oh..er...uh..well, he asked for a..private..chat.." Harry stammered not looking her in the face.
Hermione cocked her head slightly. "What about?"
"Umm..Just a..guy to guy chat." Harry looked at his knees, hoping that she hadn't heard the last few minutes of chat but knowing she had.
"Wha-? Oh!" Hermione gave a little squeak of knowing that was ever so familiar and said no more. For a few moments, silence reigned. "Well..I'd best be going to bed now.."
"Have you ever kissed anyone?" The words rushed out of his mouth as curiosity reigned. Hermione looked stunned for a moment then shyly nodded her head.
"V-Viktor. After the Yule Ball..To be honest, it wasn't any good. He's far to old." Hermione scratched the back of her head, her cheeks red.
"Oh..Ron won't be pleased.." Harry murmured.
"Please don't tell him! I-I love him. There. I think he's absolutely wonderful. After Viktor kissed me I realized who I really like." Hermione crossed her arms over her chest.
"He loves you too. He's told me a million times how pretty your hair looks or if I think that you actually like Viktor.." Harry said quietly.
"Really?" Hermione's voice quavered with excitement.
"Heck yeah."
"Thanks, Harry. Sleep tight." Hermione hugged him then dashed back up the stony steps to her bed, Harry left wondering why she was ever so excited.
(Next day, Saturday.)
Ron was groggily rubbing his eyes the next morning as he came down the steps and into the Common Room. "Never came up to bed last night. What kept you?" He asked, peering out the window to look at freshly fallen snow.
"Talking with Sirius."
"Oh, okay. When's breakfast? I'm starved." And together, they trooped down to breakfast in the Great Hall where Hermione was sitting patiently, eating from a plate that was stacked high with sausages, toast and bacon.
"Morning!" She said brightly. Something was different, Harry noticed as they ate- Ron ate as he usually did; mouth open, crammed with food. But Hermione was not watching with the usual repulsion; she happily ate, not bothering to snap a retort or tell Ron to shut his mouth when Ron talked as he chewed.
"W'at?" Ron asked, barely able to close his mouth as it was stuffed with eggs and bacon.
"Nothing, nothing." She said, waving her hand airily.
"Hmph. Well, Harry, we need to get that essay for Snape done. I don't want to but.."
"If you need help, I can always supply." Hermione said, standing up after finishing her food.
"Really?!" Ron asked. "You said you weren't gonna help us any more!"
"I've had a change of heart." Hermione (to both Harry and Ron's shock) leaned over and kissed Ron on the cheek before leaving. He and Ron stared at each other then followed her- she had apparently walked swiftly as she was sitting in the Common Room when they arrived. Ron sat next to Hermione, Harry chose a squashy armchair across from them. Beaming at them she began to check off Harry's essay and once it was completed Harry recognized his dismissal. Smirking, he threw a glance over his shoulder at Hermione and Ron, who were now holding hands, as he walked across to room to sit at a table in the far corner, still able to observe Ron and Hermione. It seemed to go in slow motion- Ron's hand brushed her cheek, lightly cupping it (Harry wondered how he could make it look so easy) and plunged his lips onto hers. Hermione did not object but dug her hands into his hair and returned the kiss full-force. They were soon getting very intimate, Ron laying on his back on the couch and Hermione on top of him, kissing as though glued onto each other by the mouth. Harry crept out the portrait hole, careful not to disturb them.
Hermione was surprised when Ron slowly intertwined his fingers with hers but didn't object. If all went as planned, they might end up dating although that was a bit of a high hope- suddenly Ron leaned in, looked into her eyes and took the plunge. His lips were soft and warm on her's and she felt like she could fly. It didn't feel like it was with Viktor, lacking warmth and enjoyment. No, this kiss was different. Ron was taking it slow and gentle whereas Viktor was harsh and needy. Slowly, Ron placed one of his hands on the small of her back and the other behind her head, all the while not breaking the kiss. His tongue traced her top lip and was soon in her mouth (altogether, the whole idea of snogging slightly disturbed her as you were all in all sharing saliva but this didn't matter anymore.) and she swirled her tongue with his, burying her hands in his vibrant hair. Ron moved his hand away and planted it on her hip which was perfectly fine for Hermione. Though Hermione hardly realized it had happened, Ron was on his back and she was lying on his chest, still ferociously making out. Ron retracted his lips slightly.
"It's a-a Hogsmeade weekend..I'm staying here but I-I thought-"
"I think it's much more interesting here.." Hermione was surprised at how low her voice was and how sexy it sounded. "We should go somewhere more..private.." Ron nodded and helped her up, leading her to the Boys' Dorms. Hermione noticed it was empty except for them. Ron leaned forwards again and slowly kissed her again. Hermione was surprised but delighted when Ron took a more dominant role and kissed her more deeply then pushed her onto the bed (gently of course).
He didn't know quite how it happened, but now Hermione was laying on her back on his bed and he was on top of her, kissing and nibbling her neck. Her skin was sweet and smooth. He laid a delicate kiss behind her ear and she gave a soft moan. Her cheeks were flushed and small beads of sweat were dripping down her forehead. He had once dreamed of something like this..her laying on his bed, actually wanting him. His crush, love, dream. Beautiful..her frizzy curls were splayed around her head like a bizarre veil. Now it was time for reality. This could actually be happened- and it was. She reached up and undid the first few buttons of his shirt, smiling reached over and pulled his shirt off, leaving him in jeans. Hermione bit her lip, studying his was all very new to him as his kiss with her had been his first. She looked so experianced compared to him- she was sitting on his bed. His bed. And ever so sexily, she sunk her smooth, red lips onto his and straddled his lap. Ron hoped she couldn't feel his very prominent erection..But as they made out, she rocked her hips slightly back and forth, rubbing against him. She twisted her tongue around with his and it felt so good and although he wasn't sure if he should, he carefully dipped his hands under her shirt. Hermione moaned against his mouth and he took this as a green light. He cupped her breasts over the fabric of her bra and gently massaged them,making Hermione grind harder against him, almost making him climax in his pants. Merlin. Get it together. Ron thought, taking a leap and pulling her thin, cotton shirt from her. Hermione broke the kiss to get it over her head. He stared for a moment, her breasts were ample and only partially covered by her bra- her bra. It was black and lacy with a little bow and a few rhinestones.
"Mione!" Ron gasped before he could help himself. Hermione shyly tucked a strand of hair behind her ear.
"Do you like it?" She asked, cheeks flushing.
"Beautiful."
"I thought you'd like it.."
"No."
"What?"
"You. You're beautiful. It doesn't matter what you wear." Hermione threw herself onto Ron. He was slightly surprised by it but that didn't fase her. She kissed him fiercely, her tongue dancing with his and her hands exploring his body. Ron groaned against her mouth as her hands began to undo his fly and yanked down his jeans which fell to the floor, leaving him only in boxers. She was so hot as she wriggled out of her jeans and straddled him wearing only her lcy bra and matching thong. He took a sharp intake of breath as she bucked her hips while sitting on his lap. The crotch of her thong rubbing him through his boxers. Hermione's eyes were screwed shut and her nails dug into his shoulders as she ground against him. Her breathing slowed and glancing at the wet patch on his underwear she offered a guilty smile. Ron could hardly take it but wasn't positive she wanted all-out sex. If he could, he wanted to make her cum. He would. He latched his lips on her neck and sucked while his hand traced her through the silken fabric. She moaned. Slowly he increased his pace, feeling the dampness of her until-
"Oh..Ohh..Ronnn!" Hermione gasped and moaned, bucking her pussy against his hand as she came. It was all so perfect, her hair cascading around her rosy face. She was so beautiful and he felt like he could die of elation. Hermione regained her clarity and waved her wand so the curtains closed. Then she murmured under her breath and her stomach turned red then back to normal.
"Wha-?" He asked, indicating her stomach.
"Contraceptive Charm." She smiled, removing her bra. Ron felt his arousal grow harder if possible as she removed her undergarments- her breasts weren't massive but big enough to fill his hands with little erect nipples, and in between her legs there was a patch of curly brown hair that was slightly damp.
Hermione watched intently as Ron removed his boxers- he was quite large in girth and in length. He was bigger than she thought he would be..yet she was excited and felt heat pooling in between her thighs. "Are you sure?" Ron asked, leaning over her, his cock pressing against her slick entrance.
"Please." Hermione whimpered. She looked into his eyes and saw an apology behind them and in one, quick thrust, he broke her virginity. It felt like someone electricly shocked her crotch. She cried out from pain and noticed that Ron dared not move. A minute or two pass before she was able to adjust.
"Okay..you can move..just took a moment to adjust.." She panted. Ron carefully pulled his hips back and slowly pressed back in, biting his lip. The feel of his cock was becoming slowly more comfortable; more natural. He rested his head on her shoulder as his hips worked back and forth, slowly but surely. His pelvic bone rubbed her clit with every thrust and he groaned when she thrust her hips against him, applying more pressure and friction. She felt her womb clench and she felt desire fill her up.
"Go faster!" she begged. The velvety skin of his shaft created a delightful friction against her g-spot and instinctively, hooked her legs around his back and locked her ankles providing deep penetration as Ron picked up his pace, thrusting back and forth more forcefully. Hermione moaned loudly, clenching her muscles to show her approval. "Don't..stop!" She managed to get out, the pleasure overwhelming. His cock was becoming a pressure and Ron thrust into her a few more times then came, crying out her name. It made her feel so excellently feminine. She felt his hot, sticky cum fill her and he managed a few more slow thrust then pulled his cock out of her, some of his seed spilling onto the bed.
"That was bloody brilliant." Ron said, his breaths heavy.
"Oh my fucking God." Hermione breathed, looking into his eyes.
"That's gotta be the first time I've heard you sworn." Ron laughed, kissing her lightly on the cheek.
"Oh shut up, Ron and pass me my bra."
