Intercourse

Chapter One: The Hesitation Before You Go All the Way

Kissing was an interesting sensation.

They had something similar to it on Mars, but it was nothing like what Conner did to her. It was amazing the things non-telepaths, entirely physical beings, could come up with in their efforts to grow closer to one another. Physical intimacy was such a wonderful invention, a way of growing closer without the slightest use of telepathic ability; and yet, as wonderful as it was, its was also somewhat sad that physical beings like humans and kryptonians could grow no closer to one another than their skins would allow. Marvelous and yet melancholy, M'gann was still trying to grok it in fullness.

Conner held both her arms in his strong hands, one thumb caressing her upper arm in a back and forth motion that tickled slightly and sent small shivers down that whole side of her green-skinned humanoid body. He must have liked the way she reacted because his other arm then slithered around her waist to the small of her back. He was always doing that, his hands always roving, always exploring, re-familiarizing himself with a landscape that often changed as suited her mood. Today's mood had her augmenting her standard green humanoid form with slightly narrower shoulders than she'd had the previous day, but slightly rounder hips that made her (in his mind's eye) appear so much more deliciously female.

She explored his body too, but Conner's landscape never changed much. She snaked her hands up under the hem of his t-shirt to run her palms over the smooth and perfectly chiseled muscle of his chest. Feeling up the flat plain of his stomach and abs, over the slightly convex juncture between his ribs, to caress the toned perfection that were his pectorals. Her hands were tickled by the sparse bit of chest-hair he was sprouting and she delighted in the sensation, grokked it and cherished it. To show her pleasure she deepened the kiss.

He had always been so hesitant to take things that extra step necessary for growing closer. True, he had been the one to kiss her back during the event that had started their relationship, but after that he had toned it down a bit. He never pressured her to move farther or move faster, though, M'gann could always sense that he wanted to. He wanted to grow closer with her, or rather, as close as a non-telepathic physical being could grow. She grokked this. But he always seemed to hold back his swirling tide of passions, as if afraid he might damage her in his fervor. Of course, his strength being what it was and his control being less than it should be, M'gann grokked that that could also be a real possibility. So, while he did not pressure her to quicken their growing closer, neither did she pressure him. Waiting would fill.

But she did offer him the invitation.

Parting her lips slightly and allowing her short, pink, human-shaped tongue to dart out experimentally. She flicked it across his bottom lip, requesting entrance. Conner's lips parted at her request and she could not help the moan of pleasure that erupted up from her human-shaped throat.

The hand that had been caressing her arm inched its way around to her front and cupped one small round breast, his thumb rubbing slowly over it, back and forth.

M'gann understood that breasts on the human body were more than a simple organ for nurturing young. The touching and caressing of breasts was also a key method in the human ritual for growing closer. This she had grokked (not from her show, 'Hello, Megan') but rather from talking with her female friends, both Team and civilian alike. She could not contain her joy at the realization that their growing closer had advanced to this intimate degree. Her pleasure was expressed as another, more hearty and throaty moan than the previous one and her tongue delved deeper in his open and inviting mouth, exploring and tasting all that was Conner, grokking him in fullness and cherishing the feelings.

…And then he did something she did not grok.

A feeling, almost a resolve had solidified. A desire… no, a need, but a hesitance to express it and then a gentle determination.

Both his hands closed around her dainty waist, just above the luscious curve she'd given to her hips that morning. Lifting her up, Conner moved her from where she sat on the couch onto his lap. His jeans were tented with his desire to grow even closer with her and when its peak brushed against the juncture between her thighs the sensation sent a jolt through her. A realization like an electric shock. Conner was not a telepath, he was a physical being, and physical beings grew closer through a different means than martians. Namely through coupling, the process by which eggs were also quickened. On Mars they were two completely different things, but on Earth they were one in the same.

Hello, M'gann!

She had been stupid not to realize that sooner! She knew it, but she hadn't realized… She hadn't grokked the full implications.

M'gann broke the kiss instantly and sat staring at him, her mahogany colored eyes meeting his crystal blue ones. His piqued desire still pressed at her through the fabric of his cargo-pants, driving home a point so significant she felt like an ignorant nestling for not grokking it sooner.

"I'm sorry!" They both gasped at the same moment. "You're sorry? I'm sorry. What are you sorry for?"

M'gann sighed. Shut her mouth. Waited for him to go first.

"I, uh," his face flushed with embarrassment and she felt the tent of his want receed. "I didn't mean to force you. I know… um, its supposed to be a bigger deal for girls. I… I'm not pressuring you or anything. I'm sorry. I just…"

She was quickly reminded of all the sex-education classes they gave in school. Preaching abstinence and continuously reminding the female students not to allow males to pressure them into copulation before they deemed themselves ready to quicken eggs. They presented the image of female virginity as something sacred that must be guarded at all times from the fiendish and villainous males of the planet (admittedly, this might have been an over-dramatization on her part). Poor Conner. He probably thought he had just violated some sacred human code of mating conduct. That was one problem with physical beings' methods of growing closer; they had far to many rules.

She leaned in and kissed him gently on the forehead, then the nose, then mouth so that he would know that she had not been offended. M'gann rested her forehead against his, opening a telepathic link between them, welcoming him into her mind and hoping he would understand that he had done no wrong. The fault (if there was fault) lay in her tardy realization of what growing closer with a non-telepath would entail.

/'Why are you sorry?'/ His voice in her mind seemed so natural now. It as hard to believe that less than a year had elapsed since that first telepathic contact where he had forced her out of his mind, yelling out loud to never do that to him. Now, she grokked, if he could, he would enter her mind at his leisure and invite her into his own without need for words. There was a prolonged pause before she admitted, /'Martians do it differently.'/

/'Oh.'/ His psychic thread quivered with confusion accented by embarrassment. His memory called up the image of her true white-martian form, reminding himself that while she could change her form to something more 'human' in shape, that did not make her human and it was foolish of him to assume her people did things the same way either of his parent species did. He was giving himself a mental 'kick in the head' as much as she was herself. /'Sorry. How do…'/

His thought trailed off as he then reminded himself that he didn't want to force into anything she wasn't ready for. It might be better to wait for her to volunteer said information when she was comfortable –just like he had waited for her to show him her true form, he would wait until she was ready to explain martian's growing closer to him. Waiting would fill. Such patience was not common in him and she cherished it whenever it did manifest. But social taboos against mating or growing closer were a human thing, she had no such reservations against explaining her own people's methods. The lack of explanation prior to this moment had simply been a failure to grok what growing closer to a physical being entailed.

/'Sex and intimacy aren't the same thing on Mars.'/ She used the word 'sex' specifically for his sake. The method in which white-martians reproduced was not through copulation, but what was something she grokked would be a bit much for him at this juncture. They had reached a cusp in their relationship and she wanted to make sure she took right action. Her vermillion cheeks colored a fetching shade of rosé. /'…And we don't do either of them the same way humans –and kryptonians, too, I guess- do them.'/

The embarrassment did not leave his psychic thread, and his confusion deepened. /'Oh.'/

But he did not seem to be pulling away or forcing her out, so she had not scared him away. He simply did not grok the fullness of what she had tried to explain.

/'This,'/ she continued, /'this is more like martian intimacy. A growing closer through sharing of the Self. You're not a telepath, so you can't share yourself with me this way -you can't give, I can only take.'/

He almost understood. It was a tentative grasp of what she meant. He did not grok in fullness what she was trying to communicate to him, but he was forming a picture. She just had to make sure the picture he formed was an accurate one.

/'On Mars, everyone is telepathic.'/ She knew he grokked that, but restating an already established fact felt like an easier way to lead into a more difficult explanation. /'Martian society is kinda built on it, kinda like how most Earth societies revolve around gestures.'/ To illustrate this she placed her hand over his. /'Everyone on Earth's got hands; everyone on Mars has got telepathy. Waving 'hello' is a casual gesture with no real intimacy behind it, shaking hands when you meet someone lays a path to grow closer to them later, holding hands is an expression of closeness, intertwining fingers even more so…'/ She did each of these things as she narrated.

/'Here on Earth, people grow closer through physical contact. The more personal the contact, the closer the relationship. On Mars it's the same but with telepathy. The deeper the connection, the closer the relationship. On Mars, the closest a pair can get is to almost share one mind, two parts of a whole. On Earth, instead of sharing minds, couples share bodies.'/ She blushed when she finished; the sharing of bodies was still in unfamiliar concept.

/'Okay…'/ He still did not grok. /'So, intimacy is all in the head and sex is… what?'/

Ah. Here she hesitated. Not from any silly social phobia of talking about the topic of procreation, but rather because she feared it might disgust him. Rather like she had feared her true form would disgust him. Well, he had proved her wrong once already. Time to try for two for two. /'When I said "sex" that's not what I actually meant. White-martians don't have "sex" –we spawn.'/

/'Oh.'/ Well now, that thought was heavy with disappointment. /'So, you can't… you don't have…'/

/'I don't have organs that are compatible with yours.'/

He sighed and leaned back against the couch. "Well that kinda sucks."

It did suck.

They seemed to have reached a point in their growing closer where no further movement could be made. He could not extend his mind as she could, if they tried to grow closer by the martian means of sharing the Self it would only violate Conner as she would have total control over their joining. It ran the risk of doing to him something similar to what the G-gnomes at Cadmus had done to him and she did not want that. As a physical being, Conner could only grow as close as his and his partner's bodies would allow.

But her body had not evolved to grow closer in that way. Growing closer was not a physical act for martians and white-martians did not reproduce through direct physical contact with one another and so there had never before been a need for physical intimacy or organs to facilitate this. She could change her form to a human shape, but that did not make her human. All it did was make her human-shaped. She might be a shape-shifter but…

…But she was a shape shifter! Why couldn't she just alter her form to accommodate the human and kryptonian method of growing closer? Hello, M'gann! A shift like that, with so much fine detail, would require a great deal of concentration and effort on her part, but once she was used to the shape and feel and grokked its fullness it would become easier for her and if it allowed her to grow closer to Conner it would be worth it. She just needed to brush up on her knowledge of human anatomy.

M'gann closed the window with the episode of 'Hello, Megan' that she had not been paying attention to and called up a fresh screen. She searched female anatomy and human intercourse. Ignoring the amateurish videos that did not look at all scientific, M'gann found a fair few medical articles and one message board dedicated to the discussion of sex. The medical articles and their corresponding diagrams were helpful, but the message board actually turned out to be more so. There she could at least ask stupid questions. Sometimes she was accused of being a troll when she asked a question that would not have made sense from a human of either gender (or anything in between for that matter, sometimes one just needs to be raised in a culture to grok its fullness).

After several hours, M'gann grokked she was ready to shift her first attempt at the shape. It was more than just a simple orifice. There were layers and folds to it, rings of flash that were supposed to feel differently at different depths. She began with the outer folds, forming a cleft between her thighs, a slit of flesh that was crowed with small bud of a nerve-cluster (many of the women on the message board had placed great importance on this nerve-cluster, M'gann ran the tip of her finger over it experimentally but felt nothing). She deepened the shift, creating folds of flesh and rings of inner-walls and more nerve clusters (she referred back to the diagrams to be sure of their exact placement).

When she was done, M'gann grokked the intimate juncture between her thighs perfectly resembled what it should look like at least visually. But that was all she could do with diagrams and descriptions. The rest she would have to figure out on her own.

She lay on her back, one hand slithering down between her legs, her fingers exploring to make sure everything was in its proper place. Everything felt as it should, the outside had folds where there should be folds, the slit was crowned with the delicate bud of nerves, the inside was tight but elastic and everything was moist and slick. It felt as it should feel… to another person. But M'gann gained no sensation from it. The nerve clusters she had so carefully placed were non-functional. Her touches and caresses while exploring had not stimulated them. More reflection was necessary before she fully grokked this newest of organs.

Days passed.

Winter vacation ended and she, Conner and Zatanna returned to school.

She and Conner continued their growing closer through kissing and other physical contacts such as hugging and handholding, but they could only grow so close using those methods alone. M'gann continued to practice the new shape and it came easier to her, but she herself felt nothing from it. She meditated on how to connect the nerves so that they worked properly, but she was yet to find the right method. The human body was a complicated organism, the human sexual organs more so. She asked the school's heath teacher and nurse some questions which they answered with hesitant candor, gave her and handful of condoms and told her to make smart choices before sending her out. She visited the library after cheerleader practice as well.

Conner asked her why one day and she told him honestly. He had looked so flattered, so pleased, so honored. It made her love him all the more when he bent down to kiss her on forehead and said that she didn't have to change anything about herself for him. He loved her just the way she was, how she looked was immaterial and whether or not they could have sex was immaterial (except she could feel that it was a material point, if only because it was wired into his genetics –on both sides.)

The answer finally presented itself one day, not from a medical journal or an anatomy diagram but instead in fiction. A literary genre called 'erotic fiction'. This was another thing that marveled her about physical beings –pornography. They had nothing like it on Mars, there was no need for it.

On a lark she had clicked a link on the sex message board she frequented. It had been posted by one of the regulars of that forum and one whom had helped M'gann on several occasions. The thread was a simple and lighthearted thread for people to share their favorite erotic art, photography and literature with one another. Most of the stuff was trash, but M'gann trusted this particular poster and so follower her link. It lead to an author's profile on a website devoted entirely to erotic fictions. It was rather like fictionpress dot com… but with sex. The author gave detailed descriptions of, not only the actions themselves (some of which were very acrobatic and creative, M'gann certainly never would have come up with them on her own) but also the feelings and sensations that resulted from said actions. Particularly, how the sensations of pleasure traveled in the body from the nerve clusters. M'gann now grokked a better idea of how the nerve clusters should be connected.

She closed the screen she'd been reading, drawing her legs up, M'gann assumed the lotus position to meditate. Delving inwards, spreading her Self through out her entire body, as she always did when shifting into an unfamiliar shape, she found the nerve clusters she had so carefully crafted almost a week ago and drew lines as she grokked they ought to be connected. Then, following the lines she had drawn, manifested nerve-connections from the clusters, held the shape in her mind to grok it in fullness then pulled her Self back into her mind. She stretched out on her back to try once again.

The shape was familiar to her now. Her fingers parted the soft lips of her labia to reveal her inner folds, her slit and the bud that crowned it. It was an act of will that allowed her to grow moist and she stroked one finger up her slick slit. The action tickled in a new way, something she wasn't familiar with but it sent butterflies into her stomach for some reason. …and when her finger brushed over the delicate bud those butterflies turned into a string of tight anticipation. She gave the bud another experimental stroke and moaned at the short wave of pleasure it produced. Yes, the ladies on the message board were right, this was a very important place.

Using the tip of her finger, she ran circles around it, then flicked the pads of her fingers over the top, then circled it some more, over the to, circle, over the top, circle, ov- Oh!

M'gann bit her lip to keep the loud moan from escaping her throat. That string of tight anticipation in her stomach had snapped and given way to a flood of pleasure that crashed on her in waves welling up from her center, from the cleft between her thighs. That was… that was… very physical.

She lay on her bed, panting slightly. It that was what it felt like on just the outside…

She snaked her over hand down, slipping one slender human-shaped finger inside. Had she grown wetter? M'gann gave a mental shrug; it helped her finger slip in all the more easily. She waggled her finger back and forth feeing her new insides, and her new insides responded favorably. M'gann found herself suppressing another groan of pleasure of the waves of her motion traveled up from her center and through out the rest of her body. If this is what it felt like with just her finger, what would it feel like with Conner? With the one it was designed for…

Thoughts of him brought on new waves of pleasure, though she had not altered her rhythm or motions at all.

She thought of how his hands felt when he held her by the arms, how his lips felt against hers, her hands over his chest, the feel of his rippling muscles under taught skin. The tent of his pants when he'd moved her onto his lap, the feel of his organ straining against the fabric to reach her, to grow closer with her…

M'gann gave up trying to suppress her moans and sighs. She let it all out with a passionate fervor. Her thoughts of Conner and her own ministrations pushing her to a shuddering climax the likes of which she had never experienced before.

She lay on her bed gasping. Yes, it was safe to say that now everything worked right.

There was a knock at her door.

M'gann found that her voice failed her so she reached out with her telepathy and found it to be Conner. /'Yes?'/

/'I, uh, I wanted to make sure you were okay.'/ His telepathic thread vibrated with concern but there was a hesitation to it, as if he were unsure if he should have disturbed her or waited until the morning to ask about it. /'I heard you, um, whimpering.'/

/'I'm fine.'/ She assured him. In fact, she felt much better than just 'fine' at the moment. /'I, um… When's the next time we'll have the Cave mostly to ourselves?'/
