Prompt: Anal Sex

Characters: 2B/9S

9S loves everything about 2B, but particularly there would be one part of her body he seems most interested in, who is she to say no?

9S was happy.

Actually, happy would be an understatement. After all the events of the Tower, and the trouble the Pods went through to rebuild them, he couldn't be more content to finally have the woman he loved at his side once and for all again.

2B was his world, his everything, and now, with no Bunker or Commander in sight, neither of them needed to hide feelings or push each other away in fear of being hurt.

Anemone, for as Leader of the Resistance she was, was not going to interfere in their relationship in the slightest, not that they thought she ever would, the Resistance had no rules about love, and he wished YoRHa hadn't either.

And 9S had the feeling she had another Number 2 on her mind that wasn't his 2B anyways.

As long as A2 didn't try to interfere he would tolerate her presence at the camp because of Anemone, after all, the two weren't friends, but they did acknowledge their faults, and that was okay.

He felt like he was living in a dream sometimes, this was way too good even if it was just that, because had it been a dream, he never would want to wake up from it.

He'd do anything that would allow him to have 2B at his side, and wanted nothing more than to spend his time with her, no matter what they were doing.

He would sit by her side when she would patiently wait while she fished, her favorite pastime. She'd sit close to him, and he'd ramble for hours and hours about some book he read or something he found, holding hands and shoulders touching.

9S loved her company, he loved her, and his favorite thing was when at night he would be lying next to her in bed, and they would wrap their arms around each other, losing themselves in passionate kisses and cuddles.

And sometimes indulge into something more intimate.

That perhaps surpassed everything on the list of things he loved doing with her.

You just want to **** 2B, don't you?

Sometimes Adam's words would still ring in his head, but so what? Yes, he wanted to make love to 2B, he wanted that so very much.

Loved to run his hands on her curves, feeling their softness, and kiss and worship every inch of her synthetic skin and metallic bones until she melted from his touch.

To invade her mouth with his, to nuzzle and squeeze her breasts, playing with her nips until she made those small sounds his ears so much loved. To lick and touch her where it was forbidden, until her juices dripped from his chin, until he was dizzy and drunk from her taste alone.

To feel her own hands and mouth touching him whenever she got so bold to allow herself to do so. To take and hold her legs, and slip his hands on the softness of her backside when he was inside of her.

That part he's always been curious about. After all it wasn't like her dress did much to cover that part too well, in fact not at all.

Now, his hands were free to roam that part of her whenever he desired, albeit with discretion, but, from his library of footage he collected from humans, he's always been curious to know just how it felt to be buried in those cheeks for once.

He never asked before, just being content to have 2B there with him, writhing from his loving attentions, and that alone was enough, yet, tonight almost seemed like the perfect opportunity to take this gamble.

Right here with his chest against her back, both naked, as his hands lost themselves in her chest, his mouth leaving marks on her neck and back, and his already erect cock pressing against those cheeks he was so curious about…

He could not let this chance pass by.

The worst she could say was no, right?

He'll accept it even if she wanted to indulge in the usual kind of activities, he knew she was too worked up, from the way she breathed, fast and irregular, to at least go through with it to the end.

It was just a matter to know if she'd be down to experiment. After all, the body was hers, and he'd never dare to hurt her or make her uncomfortable.

"Hey 2B…" he whispered against the skin of her back, giving one breast a small squeeze to get her attention.

She made a sound between some kind of moan and a one of curiosity as to why he called her.

"Are you up to try something new?"

Unconsciously his hands had already slipped downwards, coming to caress her thighs and ass already, as if already expecting her answer to be positive.

"... What?" again that breathless sound she made before that drove him crazy every time he heard it…

"I was just curious…" his hand rose further up, one finger teasing that one little hole of her ass. "... about here."

"Some humans used to do it like this too." he didn't expect her moans to be so loud just as he teased the little hole, his fingers slick from the wetness seeping through.

He grinned to himself. "Is that a yes?"

Gently, he wiggled that one finger around, gauging the same reaction as before. "You're so cute, 2B." he chuckled to himself, leaving kisses on her neck, enjoying the sounds she was making.

"I suppose then I can continue then." if her behavior was any indication he was sure she was entirely on board with this, and she punctuated it even further once he added a second finger in.

After all, she had to be prepared first, he did not want to hurt her.

For that same reason he moved so his cock was pressing against her sex, she was so wet that she'd cover him in no time in her juices in no time. Quite convenient if he had to admit.

He spent the next minutes fingering her hole, to be sure it would be stretched enough to make way for him, as his cock teased her other entrance and clit his other hand rose up to squeeze her breast, teasing her nipple between his fingers.

He gave her a kiss to her cheek, blushing red with arousal. "You ready?" he asked, giving her one last chance to drop out, however she nodded at him with a little mewl.

He had teased her enough, and he also wanted to know if it felt as good as humans claimed too. His curiosity could not be held back now.

Raising one of her legs up, he angled himself up so the tip of his cock was pressing against the hole he so carefully prepared just moments before. Slowly and carefully he made his way inside her, as panted and breathed, hands grabbing the sheets beneath them, as she adjusted to this new feeling, taking him in fully.

"So… tight…" he groaned against her back, she was so much tighter than any other time they did this…

Breathing deeply he forced himself to calm down and adjust, just like 2B was doing for him.

She turned her head towards, blue eyes meeting blue, she gave him a nod, and then a kiss. And so, lips locked he began to move with her permission.

He could hear her moan through their kiss as he thrusted into her, again and again.

Breaking their kiss first, 2B held her head backwards, her mouth open, releasing those sweet sounds he so much loved.

But he wanted more.

One of his hands was still holding her breast, as he still toyed with it, the other one that was holding her leg before, rose up on her face, he gave her cheek one gentle caress, as he slipped his thumb in her mouth, her tongue kissing it.

He didn't even need to hold her anymore as he thrusted with more vigor, she was keeping her leg up on her own, as slyly one of her own hands came to grab his own thigh, holding it with the strength of the combat model she was, and encouraging to thrust even faster than he already was doing.

Not like she needed to ask.

He happily obliged to her request, feeling the familiar tingle in his loins, the hand that held her breasts lowered itself, easily slipping into her folds as he fingered her, holding his palm against her clit for even more pleasure.

She cried loudly at the motion, tightening around his fingers almost immediately, she was just as close as he was.

With the last of his thrusts, leaving a bite to her neck, he came inside of her with a grunt that spoke of her name.

"Nines…" oh how he loved to hear her call him that way as she shook from her own orgasm…

It had to be one of his favorite sights, and sounds.

"That was… quite nice." now he understood why some humans liked it so much.

He left gentle caresses to her back as she recovered, he saw her nodding slightly. "It was… interesting." she admitted.

"Wanna try again sometime?"

She gave a little chuckle. "Maybe."
