"So, are you going to go to Hogsmeade?" Beth asked almost three weeks later. News had spread like wildfire that Mulciber had been expelled, and the students with Daily Prophet subscriptions were updating everyone else on how his trial was going. Justice was served incredibly fast in the Wizarding World. Since it was all over the papers, everyone knew what he was accused of, but not who he'd attacked. Lily was very grateful for that fact. Snape and Macnair had also remained true to their vow, the latter's head almost comically snapping away sideways when Lily and he had unexpectedly found themselves taking the same route to class. For a second it looked as though the boy was considering jumping over the railing of a staircase to give her space.

"Ah, I'm not sure," Lily replied. "You two both have dates, and I can't very well go on one so…" Lily left out that she already had plans with James. Well, not exactly with him, since he didn't know what was coming, but they involved him. You see, James had not tried to initiate or allowed anything more than kissing since her attack, and Lily was getting desperate. One week she appreciated; after all, it had been a lot to deal with, even if the assault attempt was thwarted. The second week was pushing it: she still wanted to feel desirable and not like she was now tainted or dirtied by the experience. But three weeks?! It was starting to feel like sexual torture.

Her roommates soon took their leave and Lily waved them off, only to sneak under the Invisibility Cloak and make her way to James' private chambers. He had told her the password a long time ago.

Perfect, he's in the shower. Lily smirked to herself. This made things a lot easier. She cast a muffling spell, stripped to her skivvies and grabbed the nearest book off of his night stand (of course it's on Transfiguration), flopping onto his bed so the first thing he'd see when he got out of the shower would be her thong-clad ass. She considered posing in a more sexy or seductive manner, but honestly wasn't quite sure if she could pull it off with a straight face. Hopefully this would do the trick.

Five minutes later, the sound of James choking on air told her it was working out splendidly. "Lily!" he sputtered.

She gave him her brightest smile. "Hi, boyfriend."

He chuckled, continuing to towel off his hair as he sat next to her on the edge of the mattress. "I assumed you'd be going to Hogsmeade today."

Lily snuggled into him, kissing his bare side. "You know what they say about assumptions…" she chimed.

James flung his hair towel onto a nearby chair. "No, what do they say?" he asked confused.

Lily scrunched her brows at him. "Really? Have you never heard of any idioms?"

James' hand flew into his hair. "Probably not, since I don't know what the hell idioms are. What are they?"

Lily leaned her head into his lap. "Huh. I guess I don't really know — like a saying or wordplay maybe?"

James smiled down at her, stroking her red hair lovingly. "Wordplay, eh?"

"Yeah. So they say assuming makes an ass out of… you know what, it doesn't matter, want to have sex with meee?" Lily gave the silliest, most innocent wide smile, wrapping her arms around his stomach.

"Oh." James pretended to be baffled. "Is that what you're lying around half naked for? And here I just thought maybe I kept my room too hot."

Lily began kissing her way up his torso. "Oh no, my intentions were much kinkier than that."

James squirmed when Lily's kisses on his collarbone tickled him. "Kinky you say?"

"Oh yes." Lily reached around his lap to under a pillow and pulled out a metal contraption she'd hidden there when she'd first snuck in. "Downright kinky."

James' eyes went unnaturally wide when he saw the fuzzy pink rimmed handcuffs dangling from her finger. "Babe…" He sounded almost scared. "What are those?"

Lily smirked at him devilishly. "Oh come on, I think you know. Sirius sent them to me. Says he got them from a Muggle store."

"What?!" James exclaimed, nearly jumping out of his skin. "Why would Sirius be sending you handcuffs?!" I knew he knew what they were!

"Well," Lily began timidly, "I may have owled him telling him how you didn't want to sleep with me anymore—"

"That's not true—!"

"—and he sent these and told me to tie you up and have my way with you." Lily shrugged. She looked embarrassed as she continued, "I mean, I get it if our honeymoon phase is over or something, but I—"

James turned himself around to face her and pulled her into a sitting position in front of him. "Lily. Listen to me: the honeymoon phase is far from over, in fact, I plan on being in that phase with you for the rest of our magical lives." Lily blushed and looked down to her lap. James cupped her cheeks and made her look back at him. "I want you. Good Merlin, I always want you. When you transformed into your doe and then back again last weekend like it was nothing, I nearly took you right then and there in the forest."

"Then why didn't you?" Lily whispered.

"Because… I don't want you to think that I only want you for sex. And what happened to you." He ran his hand through his hair anxiously. "And, honestly, I'm still kind of embarrassed about how much I cried in front of you with all of my confessions, and really, I guess, I just don't want to fuck this up." He swallowed thickly and leaned his forehead against hers.

Lily brought her fingernails up against the back of his neck and into his hair comfortingly. "You can't fuck this up. We're in it." She kissed him gently and he achingly reciprocated.

When their lips parted, he chuckled. "I can't believe you wrote to Sirius about wanting to bed me."

"Hey now, don't act scandalized. He's my friend too and somehow he already knew all about our sex life."

James' brows lifted in mock surprise. "Hm. Imagine that. How curious."

"Curious indeed," Lily teased, pushing James onto his back and swinging a leg over his hips.

"Lily…" James said cautiously even though his hands still instinctively came up to rest on her milky thighs.

"Relax James, I'll go easy on you." She gave him a saucy wink while grabbing a wrist to cuff and leaning forward against him to sling the metal through the pillars of his headboard.

James fake chomped at one of her laced up breasts currently positioned right above his face. "Easy on me, eh?"

Lily pulled his other hand up and secured the wrist. "Yes, if you're good." She reached into her bra's cup and pulled out a small silver key, placing it on his nightstand.

"Well, that looks awfully misplace-able."

Lily smiled as she reached for his glasses and set them down right next to his freedom. She appreciated how much more boyish he looked without them on his straight nose. "Don't worry. I'm a witch. I'm pretty sure I could get you out safely. Unless I," she pushed her wand off the bed and they heard it clatter and roll on the floor, "whoops, lose my wand too."

James' eyes narrowed at her on top of him. "You're enjoying this a little too much."

xXx

Lily ran her nails down his chest, stopping at his knotted towel just in front of her hips. "And you, my love, just need to let go." She leaned over him and whispered, "Because I don't know if you noticed," she licked his ear's rim, "I'm in control now." She felt the shiver that traveled down his body via her thighs and was more than thrilled when she sat back down to feel his raging erection pressing into her flesh. She opened up the towel and watched as his freed cock slapped up against his lower abs, ready for action.

"You sure?" James flexed his arms, testing the resistance of his metal bonds.

Lily perched up on her knees so she could drag her knickers down and then shifted her weight back, settling between his muscular legs to slip them off completely. His breathing hitched when he could suddenly see her cunt fully displayed below him. The air became thick with the smell of her wetness. It reeked of sex. "Yeah, pretty sure." She smiled as he hadn't stopped staring, his lips parted in awe. Her left hand came down to rub at her clit, finally snapping James out of his hypnosis. Lily guessed it had been a hard three weeks for him as well. "Then again, if you're not ready, you can just watch me?" Lily let out an exaggerated moan as she upped the pressure of her fingers, making faster and faster circles around her bundle of nerves. Her legs were draped over his, so every time she flexed her hips, she was lightly grazing the underside of his balls. She knew she was torturing him a little, but at the same time, she thought it was well deserved. After all, hadn't he been the one denying her for three bloody weeks, even from their dream time escapades? Lily had nearly considered blowing up Slughorn's potions ingredients cupboard to ensure he wouldn't be able to make any more of those pesky Lily-sex-dream-repelling potions.

"Fuck," James growled and fought against his cuffs once more. "Lily, let me touch you." He looked so pained. "Please."

Lily ignored his pleas for a few more minutes as she began to feel the effects of her own ministrations on her body. She brought her free hand up to her breast, kneading it through her bra, as the feelings inside of her started clenching and pulsing. From the corner of her eye, she saw his cock twitch, utterly jealous to be left out of this debauchery, but she didn't care — she was determined to maintain her gaze squarely on her restrained boyfriend's lust-filled eyes. Eyes which were becoming darker and darker with every spasm her body emanated.

"Lily, uncuff me," he demanded, sounding about ready to fuck her silly for days.

Lily pushed herself up into a sitting position and then leaned forward. "No." She shifted her hips back and her tongue escaped her mouth to lick him from his base up his shaft.

James involuntarily jerked his hips, yanking his arms above his head to no avail. "Lily, fuckin' hell," he moaned out.

Lily smiled and then took his penis into her mouth, tasting his precum, humming vibrations as she pumped with her hands.

James writhed under her work and she watched as all his muscles flexed in response. His biceps… I feel like I've been under-appreciating his gorgeous bulging biceps. Lily had heard of people loving a certain body part of their partner, but what were you supposed to do when every part was fucking ridiculously hot? It wasn't fair. How was a witch ever supposed to have any self-control in his presence? Well, you kind of don't, so that answers that question.

"Babe," he groaned with half closed eyes, "I want to be inside you." His dirty request sounded so sincere, she almost felt inclined to indulge him immediately. Almost.

Lily brought her chin up and grinned mischievously. "You are inside my mouth."

James let out a frustrated sigh, adjusting his hips. "Lils… please."

Lily figured that was enough pleading for one day. She positioned her body over him, supporting herself against his chest. "As you wish," she recycled his line on him, kissing him as she lowered her pussy down to where he wanted it.

He bit his lip hard as he felt her tightness settle all around him. "Thank you." He couldn't stop the words from spilling from his mouth.

"Any time," she responded breathlessly as she began to ride him for all he was worth. It was most certainly different to not feel his hands all over her while they were making love, but Lily guessed she was trading the kinesthetic experience for a more visual one. And what a sight it truly was to have James be tied up beneath her with his arms pinned over his head. Her vagina clenched. Apparently it had a psychological payoff too: she felt powerful, she felt sexy, she felt — well — untouchable.

"Lily…" James looked like he was hanging on by a thread as she jerked his body up and down the bed. He hadn't been able to keep her name off his tongue since she'd begun.

Seeing him look at her the way he was made her lose it for the second time. She heard squelching, watery noises, but she didn't care; it was as though her mind had just exploded in a flurry of colors behind her eyeballs. She was only vaguely aware that she was crying out — loudly — as her nails dug into his pecs and her hips continued with a few powerful, spastic grinds. This is what drugs must feel like, was an insane thought that floated through her brain as she tried panting her way to normalcy, swaying back and forth. Well, I'm officially a fucking addict then.

xXx

When she opened her lids, James was smirking up at her. "All right, Evans?" He sounded ridiculously pleased with himself.

"Yes, Potter, doing great, thanks for asking," she replied, allowing herself to fall onto the mattress next to him so she could snuggle to his side. "I should tie you up more often." She nuzzled her face against his arm. No woman should be this into her man's sweat, it isn't right… it's damn dangerous.

James chuckled, turning his head to her. "You know what, I didn't hate it." He winked at her.

Her eyes went wide. "Oh no, did you come? I'm sorry, I got so into myself."

He grinned ever so tantalizingly. "I know. That's why I came five minutes ago."

"Really?" He nodded exuberantly. "But we kept going; doesn't that hurt for you?"

James shrugged, making his chain rattle. "No. I was still enjoying myself watching you."

Lily hit his abs to reprimand his naughtiness, but was met with a wet slapping noise instead of the expected sound of tight skin. She looked down confused. James' loins and abs were covered in moisture. "Um, what's that?" Lily was pretty sure he hadn't just remained wet there from his shower.

"Uh…" James fumbled, craning his head from the moist mess to his girlfriend. "You came?" he said tentatively.

"Yeah." Lily was confused.

"Right," James continued hesitantly. He wasn't sure what Lily knew (seemed like not a whole lot on this particular subject) and he didn't want to embarrass her. "So, this is normal. Sometimes."

Lily's eyebrows shot way up her forehead. "Wait, you're saying this," she motioned in his abs' direction, "is from me?"

James shifted uncomfortably. He really wanted to grab for her hand but realized his hands were still cuffed. "Lily, it's natural." Lily somehow looked even more mortified. "You squirted. It was hot."

She propped herself up on an elbow over him. "I what?!"

James shrunk a little bit under her glower. "Babe, can you please uncuff me so we can have a normal conversation about this?"

Lily scoffed but reached for the key, releasing James so he could rub at his wrists tenderly. It seemed he too had gotten a little carried away by the fantasy. He then immediately kissed her, threading his hands through her hair. "That was so sexy, you have no idea," he whispered to her.

Lily leaned into his shoulder. "Mm, no distracting me."

He rubbed her back soothingly. "Lily, please don't be embarrassed. There's no need. When I come, things get wet, when you come, things sometimes get wet too: that's sex." Lily laughed and bit his shoulder for something to do with her mouth amongst this awkwardness. She knew she shouldn't feel ashamed, but it's always rather startling when your body does something completely unexpected without your permission like that. "And I wasn't kidding: you looked so fucking into it with your hair flying and your screaming and bloody hell…" he trailed off. "I'm sorry, where was I?"

Lily pushed him away, smiling through her blush. "Okay, okay, I can come any way I like, I get it."

James pulled Lily back into him. "Yes love, please come any way you like all over me."

Lily giggled, but abruptly stopped when there was a sharp knock on the door.

"Professor? Are you still holding office hours today?"

Lily and James both groaned. Well, that was most certainly one way to remind you that you were still, in fact, inside of a school and probably shouldn't be doing any of this.

"Uh, one moment please!" James stammered out, but there was another knock.

"Oh!" Lily swung her upper half over the edge of the bed, reaching for her wand. "I put a muffling charm on the door." She settled back next to him. "One second… there." She took off the spell and cleaned up his body while she was at it.

"Professor?"

James kissed her temple whispering a thank you. "One moment please, I'll be right out!" They heard footsteps shuffling away in the classroom. James dropped his face into Lily's chest. "Ugh, I'm the worst teacher ever," he whined. "I completely forgot I had office hours today, and I'm behind grading papers, and Remus still isn't answering any of my owls and—"

Lily broke his rant by pulling him up and planting her lips against his. She smiled when she saw him taking a deep breath in through his nose and out his mouth. She reached over for his glasses and perched them back on his nose. "You are a great professor. You got this."

He looked at her through thick lashes. "Stay here so I can hang with you after?"

"Okay." He smiled so big she could see his cute cheek dimple. "I'll just take a nap or something."

"Perfect," he said strutting out of bed towards the door.

"James!" she whisper-yelled before he reached for the doorknob. "You might want to put some clothes on first!"

He turned around sheepishly, still fully nude, making for his closet and grabbing a pair of trousers and a shirt. He hopped in, giving Lily a peck on the head as he got dressed. "What would I do without you?"

"Be truly and utterly embarrassed, I presume."

He finished with his top button and popped down his collar. "Wish me luck," he said, walking to the door for the second time.

"You don't need it, Professor," she teased.

He gave her an eye-roll before exiting and she heard him greet a student and apologize for losing track of time while he showered. Lily sniggered to herself thinking of the poor girl he was talking to. James really should never allude to being anything but fully dressed at all times for the good of anyone else's poor hormones.

Lily slowly got redressed and looked around for something to do. She'd told him she'd sleep so he wouldn't feel bad leaving her, but in all honesty, she was far too amped after that romp to do anything of the sort.

Her eyes landed upon a stack of papers next to his favorite armchair by the fireplace. She wandered over and settled down grabbing his quill and red ink. How hard can 3rd year papers be? If anything, it will be like revising my basics. And so she did, easily finishing the essays and the 6th year tests.

"Professor?"

James snapped back to reality after having been caught daydreaming in his office. Try as he might, he could not quite dispel images of Lily gyrating on top of him in her bra — clearly having the time of her life and succumbing to her most powerful orgasm yet. And he hadn't been lying, her leaking out on him was sexy. Her jaw had been slack, her green eyes glowing before she sealed them shut, and her body had given herself completely up to rapture. What more could any man want than for his love to be so absolutely overwhelmed from just him inside of her? It was insane. And it was clear Lily got off on having dominance over him… and yeah, he may have gotten a bit of a thrill from being overpowered like that too. It was a nice change from always being in command as a professor… an Auror… Quidditch Captain, Head Boy, leader of the Marauders… fuck. He loved that Lily tied him down and had her way with him as Sirius had suggested.

He shuddered. Why the hell did his best mate know this about him? 'Masochist…'

"Right, sorry Melissa, say that one more time?" James had felt very relieved when he'd seen it was the 6th year Slytherin prefect waiting for him. He knew from her test scores and class participation that she was very smart and understood his subject, but she came to every office hours all the same, and James wasn't thick enough not to know why.

"I just don't understand why conjuring finches is so much easier than conjuring lovebirds," she asked, twirling a long black lock around her forefinger.

Oh boy.

When James had finally given the lovestruck student enough face-time for her liking — not a problem he'd imagined having when he'd agreed to take this job — he snuck back into his room and kissed Lily sitting in his chair before sinking to the floor by her feet and leaning back against her knees. "I think I'm gonna go back to Auroring after this. If I can survive teenage girls, I can survive anything."

"Hey now," Lily objected as she ran her fingers through his chaotic hair, making him lean further into her, loving it. "Your girlfriend is a teenage girl."

"Oy, don't remind me," he joked, earning himself a slap on the shoulder. He tilted his head up to look at her. "Wait, what are you doing?"

Lily collected all the papers strewn across her lap and moved them back to his side table. "Just helping you out," she said nonchalantly.

He grabbed the papers, mouth comically hanging open, flipping through her corrections. He put them back and twisted onto his knees to face her. "Lily Evans, have I told you," he seized her hand, kissing it, "you are the most brilliant," he kissed her forearm, "magnificent," kissed her shoulder, "wonderful witch I have ever met?" His kisses devolved to blowing raspberries on her neck, causing her to giggle against him.

"All right, all right, I'm brill, stop!" she gasped out.

He stilled and brought his nose against her cute sloped one. "Thank you. Seriously."

She threw her arms around his shoulders. His kneeled position in front of her here brought all the fuzzy feelings of telling him she loved him for the first time back to her stomach. "Well, it wasn't completely selfless of me, I was sorta hoping we could go on another date now?"

"Oh yeah? What did you have in mind?"

She smiled like an overexcited eleven year old — which was actually how old she'd been when she'd decided she very much would like to do this with a boy she liked one day. "Have you ever gone to the movies?"

"Oh, the long, speaking pictures Muggles watch in a crowded dark room?"

Lily tilted her head. "I guess, yeah."

"No!" James said gleefully. "Would you like to take me?"

"Yes!" Lily cried, jumping to her feet and hauling him up with her. "I brought Muggle money and I figured we could just Apparate to any Muggle city and pop in. Maybe grab a bite to eat afterwards?"

"Sounds perfect," James said picking up his Invisibility Cloak and her hand, ready to sneak off to the Forbidden Forest. "And you can show me that Apparation you've been mastering."

Lily gave him a skeptical look. "I don't quite know if I'm good enough for Side-Along Apparation yet."

James gave her a wink. "I trust you."
