(A/N: There are a few things I'd like to say before we jump into the next chapter. First, it has been many years since I was a virgin and I think I've finally forgotten what it was like. There were several points in this chapter where I was just starring at my screen going "uhh…" So, don't expect to much from this chapter. Secondly, while its not relevant in any way, I'd just like to share that this story is the first time I've tried writing smut since my incredibly messy break-up last September.)

Intercourse

Chapter Two: The Awkwardness of Getting Acquainted with Each Other's Bodies

On New Years, after the Team had saved the League from what later became referred to as the 'Mole Debacle of 2010', Superboy and Superman had exchanged names. Civilian names, that is. Superboy now knew that Superman was Clark Kent, a reporter for the Daily Planet living in Metropolis; and Superman now knew that Superboy was Conner Kent, a student at the Happy Harbor High school closest to Mt. Justice. They were now, not only speaking to one another, but also on a first-name basis.

However, this did not make them friends. At best, they were polite acquaintances.

But, Superman –or, Clark, rather- had agreed to finally mentor him. They agreed upon a schedule that allowed Conner to continue living at the Cave and did not cut into Clark's civilian life in Metropolis, but still offered Superboy the chance to work under the guidance of his genetic parent (well, one of his genetic parents –Superman didn't know that he was also half Luthor and it was gonna stay that way!). The final settlement was for Superboy to act as Superman's side-kick in the city for one weekend every month.

This weekend was his first weekend with the Man of Steel, but Conner's head wasn't in the game. No, his thoughts resided a few miles north in a Cave beneath the small mountain peak beside a small Harbor town. His thoughts rested on M'gann and on what she had told him during the week.

She had developed a keen interest in human anatomy since returning from winter vacation and spent several hours after school at the local library, poring over medical textbooks. When his impatience at having to sit quietly finally gave out and he asked her what she was doing, she shocked him.

M'gann told him over the break that they couldn't have sex because white-martians didn't have the appropriate organs for the act. This fact had disappointed him (more than he would ever admit –especially not to her) but he tried not to let it bother him because he'd rather live in celibacy and be with her than have all the wild and crazy and imaginative sex in the world but no M'gann. It was M'gann he wanted and if he had to go a lifetime never experiencing intercourse then that was the price he'd pay. It would certainly make his high school Heath teacher happy, 'Abstinence till Death! Abstinence till Death!'

But M'gann wanted to remain abstinent about as much as he did, that is to say, not very much at all. But he couldn't do the martian equivalent of sex, so she was using her shape-shifter ability to make a way for them to 'grow closer' (as she called it) through physical means. It made his heart sing to know that she cared about him so much that she'd do that for him. He wanted to meet her half way. If she was looking for a way to couple with him physically, then he was going to try his damnedest to find a way to couple with her telepathically! He just had absolutely no idea how to even start.

Someone was snapping their fingers in his face.

"Conner? Anyone home?"

He blinked. "Oh. Sorry, Clark, I was just… thinking…"

…

He came home late that Sunday night to find M'gann still up waiting for him. She didn't have to wait for him, but the fact that she had warmed his heart.

"Hi." He tossed his overnight bag (now containing fewer shirts than he had started the weekend with) onto the couch before wrapping an arm around her, pulling her to him and kissing her gently on the lips.

She responded instantly, wrapping her arms around his waist and pressing her body flush against his. Her lips parted and her tongue darted out demanding entry. He was all to happy to accept her request and his lips divided enough for his own tongue to slither out to meet hers. Kissing her was wonderful! They had both been clumsy at it at first, but after much practice they had finally gotten it right. Very right, in his opinion.

Conner felt himself go rigid at the moan that escaped her and he broke the kiss, pulling away before she could drive him to the edges of his deplorably weak self-control. "You missed me." He smiled at her. "I was only gone two days."

She smiled at him. "I have a surprise for you. Follow me."

Pulling him by the hand, M'gann lead them both out of the common room down the corridor to her bedroom. His overnight bag from his weekend with Superman drifted behind them and very politely let itself into Conner's room so that he wouldn't have to think about it. M'gann dragged him into her own room and shut the door.

"The Team's all gone home for the week. Zatanna's already gone to bed." She said and whipped his shirt up and off. "We've got the Cave more or less to ourselves."

"What are you doing?" Conner had very few reservations about stripping. Goodness knew his bare chest saw more sunlight than his T-shirts ever did. But he was used to removing his clothes himself and not having M'gann tear at them for him, and when her hands closed around the buckle of his belt, he decided some explanation was necessary.

/'Your cloths are in the way.'/ She explained, opening a mental link for them to continue communication even after she floated up to once again press her lips against his. His belt fell open and soon the fly of his jeans was slowly unzipping itself as her hands roved over his back and shoulders.

Conner would have been lying if he said he didn't like this sudden attention. But where could it possibly be going? Not to the bed. They couldn't do that sort of thing with each other. Unless M'gann had already succeeded in shape-shifting a way for them to… /'In the way of what?'/

His jeans slipped off his narrow hips easily enough, the canvas-like material pooling around his boots. She stroked her hand along his stiff member, still contained in his cotton tighty-whiteies. /'In the way of our growing closer.'/

That last thought of hers was heady and thick and made Conner quake with anticipation. Had she always been naked? No, she had been wearing cloths when he came in. Somewhere between then and now they had disappeared though. He caressed a hand over her shoulder, down her arm and back up her front to cup her breast, enjoying the full roundness of it and only mildly noted that a nipple seemed to be in absence. Conner paused.

/'Are you sure you can do this?'/

She continued to stroke his shaft. /'Yes.'/

Her hand felt so good on his erection and this was just through the fabric of his underwear. How good would her hand feel with nothing between them? How good would it feel for him to slip inside her? His tip drooled with excitement at the prospect and she curiously rubber her fingers over the tiny spot of moisture it left on his briefs.

/'It does that.'/ He told her by way of explanation.

She broke the kiss, sinking to her knees in front of him. "I want to see it."

…And in an instant, his underwear was yanked downwards to join his pants.

M'gann blinked at it. Long and thick and hard. It was a slightly redder flesh-tone then compared to the rest of his olive skin and this intrigued her. She ran her hand curiously up his shaft, feeling the way his foreskin shifted over the hard member sheathed in it. She ruffled the patch of curly dark pubic hair that grew at its base and then lowered her hand down to cup his balls. It was all so new to her. She had done the research, seen the pictures and watched the videos, but having a male organ in front of her in real life was so new, so strange, so… alien. It would be some time, she decided, before she'd be able to grok it in fullness.

His balls were heavy in her hand and had a pungent musk to them. M'gann wasn't quite sure whether or not she liked the smell, but it was interesting. All of him was interesting. She tickled the inside of his thighs, feeling the muscles ripple just beneath the skin, she liked that. His muscles. All of his muscles were nice. Nice to look at, nice to touch, just all around nice.

Both her hands returned to his stiff and quivering shaft, gently stroking it. /'This feels good.'/

It wasn't a question, she had left their minds linked and could feel his pleasure at her touch and his want for more.

Her eyes fell on his tip and the bead of pre-cum that had formed from her motions. On a random impulse her tongue darted out and flicked across the head of his shaft, licking up that tiny bead.

"Oh god!" Conner sighed and fell backwards against the door with a slight thunk. He, apparently, liked that very much.

His pre-cum tasted… interesting. It was slightly sweet, but also salty and not quite all that pleasant. But licking his organ had apparently given him great pleasure and so M'gann tried it again, his shaft this time, rather than the head. Long languid strokes along the sides, over the top and up the underside.

He had to grip the sides of the doorframe for balance as he found that his legs suddenly didn't want to hold him up, his fingers making small dents in the metal paneling. Where had M'gann learned all of this in such a short amount of time? At the moment, he didn't care.

She paused. Noticed his hands digging into her doorframe. Stood.

He whimpered in protest, not wanting her to stop.

/'We should move to the bed.'/ She told him.

"Right." He said aloud. Attempted to take a step. Forgot his pants were still tangled around his ankles. Tripped and fell. The floor now sported a dent roughly shaped like Conner's face in an expression of indignation. He snarled and growled as he sat up to pull his boots off before finally managing to pull his jeans and underwear all the way off. "I wish I could just will my cloths away like you do."

M'gann gave a soft giggle at his comment. She sat on the bed rather enjoying the site of him sitting on her floor wearing skin and nothing else. There was something so very natural about it.

/'The mood hasn't been spoiled.'/ She observed. Even if their minds hadn't been linked and she couldn't feel his heady arousal waft along his psychic thread, she could see it plain as day.

/'No. It hasn't.'/ The confirmation was deep with aggressive desire. He had, apparently, wanted this for a long time and wasn't going to let a little trip and stumble get in his way. He stood and stalked to the bed.

She scooted up to give him room.

He crawled over her, his eyes roving over her naked green form, taking in everything from her thick red hair to her dainty little toes. He had already noticed that her breasts were devoid of nipples, but now he also saw that she sported no pubic hair around the cleft between her thighs. Conner lowered himself onto the bed beside her, stretching out, one arm wrapping around her shoulders, the other traveling down the length of her body, feeling every curve and contour.

/'You're not going to enter me?'/ She asked, confused.

/'You got to explore me. Now I wanna do the same to you. This… this is my first time.'/ Conner reminded her.

The hand traveling down her form finally reached the juncture between her thighs and there he paused. Tentatively slipped one finger between her lips. Explored.

Conner felt along her folds, parting her lips as he did so. Everything was so wonderfully moist! He slid one finger inside her. Her back arched at the sensation. He felt around on her inside, as deep as his finger would go. He had never touched a woman before and wasn't quite what they should feel like, but from the knowledge of biology and physiology that Cadmus had programmed him with everything seemed right. Conner withdrew his finger and M'gann whimpered in protest. She had liked that.

His fingers, now slick from her insides traveled up her slit, feeling his way to the small nub of flesh that was there. A small gasp escaped her when he caressed this most sensitive of nerve clusters and he liked that. He liked being able to make her moan and gasp and arch her back at his slightest touch.

He withdrew his hand from her and licked her wetness from his fingers. It tasted sweet and exotic –like she was, exotic and brimming with good-natured sweetness. He liked it.

M'gann rolled over on top of him, straddling his narrow hips. She braced her hands on his chest, holding her self up, and gazed down into his crystal-blue eyes. She was nervous. They both were, she could feel his brittle excitement through the link. As he had said, this was their first time…

"Are you…" He began, hesitated, continued. "Are you sure you can?"

/'Yes.'/

She slid down his shaft with a gasp and a hiss. He was so much bigger than a finger. Of course, he would be, a penis was nothing like a finger, but she had failed to grok that simple fact when practicing with herself. There was no pain, when forming her organ, M'gann had not bothered to give herself a virginal hymen, but she had not expected him to fill her so… full. It was surprising.

"Are you okay?"

/'I'm fine.'/ She assured him. /'I'm… You're so big…'/

Conner could not help the snort of amusement that escaped him.

/'What?'/ She blinked down at him.

"Oh man, you sound just like a girl in a porno!" He covered his mouth with a hand to hide his giggles. "M'gann, you don't have to perform for me."

/'I wasn't "performing", I was just commenting that-'/ "-Ugh! Ya know what, it doesn't matter." She threw her arms up in defeat.

He ran his hands up the curve of her thighs and hips, feeling around to fondle her ass. "You're right. It doesn't matter."

He bucked his hips experimentally, pushing himself even deeper inside her. His organ contacting a nerve center she had never been able to reach with just her fingers alone. M'gann gasped at the sensation and doubled over on top of him, her smooth, unblemished breasts pressing against his chest.

"Sorry. Was that to much?" His voice was thick with concern. He knew his strength and just how much damage he could potentially deal to her.

/'No.'/ She assured him, pushing herself back up. She wiggled on top of him, trying to readjust her position. Now it was his turn to gasp. What ever she had done, he had liked it. M'gann tried again, wiggling her pelvis in a back and forth motion over his narrow hips.

He groaned in appreciation, his hips moving in response seemingly of their own accord. Thrusting upwards as she moved over him. There was a moment's awkwardness as they adjusted their motions to better fit with one another and then they were moving in sync. Fluid, near perfect motions so that it was difficult to tell where one ended and the other began.

The pace quickened…

…and soon both were groaning with abandon.

Conner wrapped both his strong arms around M'gann's slight frame and rolled them both over so that he was on top. She braced her feet against the mattress, adding leverage to her thrusts, forcing him as deep in her as he could possibly go. He hissed at the feeling of being so enveloped by her and lowered his face to claim her mouth in a heated kiss, his tongue darting between her lips more aggressively than he'd ever kissed her before.

M'gann moaned into his mouth, her eyes fluttering with the rush of new sensations she was experiencing, so many so fast she could not grok them all. He was full and thick within her. She was tight but elastic around him. They moved together, each motion sending gratifying shockwaves upwards from her center, into her stomach and beyond. With each thrust a string of taught anticipation was tightened, pulling her closer and closer to a climactic finish that promised ruptured euphoria…

…and so was he. Pushing himself to his own finish.

Prompted by a driving need, Conner pounded himself into her, groaning at the feel of her elastic body around him. She was so tight, but still loose enough to offer freedom of movement with little friction. …and she was so wet! Were normal women this wet? At the moment, he didn't care. All he knew was what he felt and he felt great! She writhed beneath him, keening with pleasure at his every move… or was it her every move? It was hard to tell…

They were pushing each other to one, final, writhing, gasping, groaning, finish.

M'gann bit down on his bottom lip when her pleasure came, her body shuddering with the rapture of her orgasm. Her fingers had never felt like that. Her muscles, still new and unfamiliar to her, tightened around him, trying to pull him deeper than he could go and that was the final stroke for Conner. He sighed with his final release, spilling into her with a reckless abandon.

A whisper of rational thought in the back of his head told him to roll off of her before he collapsed, and he did so. Flopping down next to her with a huff and a sigh, one arm pillowing his head, the other wrapping around her shoulders, pulling her against him.

"You're… huff…" He voice failed her so she switched back to telepathy. /'You're warm.'/ She complained.

With a jolt he was reminded that heat was her weakness and something that would be merely 'hot' for a normal human could be damaging to her. He released her shoulders and scooted away. /'Sorry.'/

/'No, its fine!'/ She instantly plastered herself to his side once again. /'I was just commenting that it was uncomfortable.'/

His arm returned to her shoulders, his hand sneaking around to fondle one round breast.

M'gann's hand drifted down to dab at the overflow from between her thighs, her hands coming back covered in the mingled fluids. She stared at it for a moment, thick and white and smelling rank. She licked her fingers experimentally in an effort to grok its fullness, instantly decided she did not like the flavor one bit and wiped her hand on the bedspread. /'Your method of growing closer is gross.'/

His mind debated between offering a non-committal response or a teasing one as he continued to fondle her breast, his thumb running over the smooth place where a nipple would have been. Conner, apparently decided on teasing. /'Whatever. You spawn. Spawning's gross.'/

/'That has nothing to do with growing closer.'/

He did not want to argue and seemed perfectly content to let her have the last word.

Eventually they rolled over on their sides, spooning, and Conner wrapped his other arm around her, both hands each claiming a breast to kneed and stroke. He played with them for a while, pushing them together, pulling them apart, pressing them against her chest. He liked how soft and pliant they felt under his hands.

Then he asked, /'So, no nipples?'/

She gave a mental shrug. /'I didn't see a purpose in having them. Martians don't lactate and they serve no sexual function.'/

For a moment it felt like he was about to disagree. She could feel the protest indistinct and unformed in his mind. But he considered her logic and finally responded with a null-feeling, /'Okay.'/

/'Would you prefer it if I had nipples?'/ She asked, honestly wanting to know. In all of her medical research she had seen no indication of nipples serving a practical function during sex. Of course, she reflected, her information was all human-based. Maybe this was a kryptonian thing. Or it could be one of those 'fetish' things they seemed to talk about on the message board a lot.

/'I like you just the way you are.'/ He assured her. But underneath his assurances M'gann could clearly sense that he was telling only a half-truth. He liked her just the way she was, cheerful, sweet, sometimes ditzy M'gann. Strong and sometimes stubborn M'gann who had, against orders, snuck into an enemy camp to restore his memories. Nervous and oblivious M'gann who broke eggs on his head and drenched him with milk when she thought to much. Vulnerable but determined M'gann who, to spite her greatest fears, showed her true form to the rest of the Team rather than allow herself to be blackmailed. That was what he loved and he did not want any of that to change one bit!

But the shell that house that M'gann, the physical skin that clothed the soul, that was something else entirely. The body was the wrong species. The body's natural organs were not compatible with his. The body's shape had been missing details to allow them to grow closer. It was the mind inside the body that he loved and did not wish to change, but what Conner failed to grok was that the mind and the body were two separate parts and the body she could easily change.

/'I can give myself nipples if you want.'/ She told him.

/'You don't have to.'/

/'Its not a big deal. Look, I can do it right now.'/

Beneath his hands, Conner the smooth surface of her breasts suddenly peak and he was then covering two perfectly shaped erect nipples. She felt how pleased the small change made him and gave a mental shake of her head for having to go through so much drama over something so small and inconsequential.

…and then his pleasure was dimmed by a twinge of guilt. /'You didn't have to…'/

/'Conner, just shut-up and enjoy them!'/ She would have to break him of this idea that changing her form was somehow changing her. She was not entirely a physical being, she was a psychic consciousness attached to a physical body. Changing the physical body, to her, was as inconsequential as changing clothes was to him. But he was a physical being and so had the unfortunate handicap of thinking that the body was also part of the Self and to change the body was to influence the Self.

He was al to happy to do as he was told. Pinking the newest augmentation between his fingers, tugging them lightly, twisting slightly. He, apparently, liked playing with them. Then, propping himself up on one elbow, Conner rolled her over back on to her back and bent down over her, taking one peaked nipple in his mouth. He sucked on it with relish, his teeth nipping at it ever so lightly, his tongue running circles around it while his other hand continued to tug and twist it twin on the other breast.

/'You know nothings gonna come out, right?'/ She asked, genuinely curious. /'They're non-functioning. And besides, we're quickened no eggs, so even if they were functional they still wouldn't do anything.'/

/'I know.'/ Conner assured her as he shifted his attention to the other, neglected nipple, repeating his sucking, nibbling and licking motions.

/'Then why…?'/

He gave a mental shrug. /'I guess I just like breasts.'/

Ah. So it was a 'fetish' thing, then.

…
