Dr. Fujimaru, or: How I Learned to Stop Worrying and Love Bottoming

Her skin feels infinitely soft under his lips. He trails kisses over her stomach, watching her belly tremble under his touch. Slowly, his hands go up to hook fingers in her panties, pulling them down her legs.

Above, Artoria, Caster, she who chants, proud owner of the third biggest libido in Chaldea, whine. "Ritsuka, hurry up!"

"Getting there, getting there." He chuckles- though to be fair, he's also very eager to give her head. He sets a hand bellow her navel, intending to use it as support to lean down-

-and immediately gets smacked in the wrist by something soft and vaguely wet.

Surprised, he removes his hand in a flash, peering down. From the corner of his eyes, he catches sight of something moving, but it's gone by the time he gets a proper look. A bug? A gust or wind? Or...

Slowly, scientifically, Ritsuka sets his hand back, and presses down Artoria's belly.

It's fascinating to watch; the further he presses, the more Artoria's clit swells, grows- and there it goes, leaving its hood to spring forward. "... Holy fucking shit."

Above, Artoria sits up on her elbows, quirking up an eyebrow. "Having fun?"

"I didn't know you could do that!" He removes his hand again. Artoria's- clit? Dick? retracts once more. This time though, the 'head' stays poking out. "Uhm. Is it supposed to...?"

"If you keep bringing it out, of course it's gonna stay there!"

He presses down again, bringing her cock out once more. As she said, when he removes his hand, it only partially retracts, a much larger portion of it hanging out this time.

So. Ritsuka's girlfriend has... a pseudo-penis. A retractable dick. Hyena-style. That's great! Bit surprising that it never came up the multiple other times he'd had sex with her, but such is life. Ritsuka can definitely deal with it. He's got experience with dicks. He's got one, for a start. For another, there was this thing with Astolfo... and this other with Fergus...

A quick clarification, before you mistunderstand anything: Ritsuka Fujimaru is a cisgender, hetereosexual man. Yes, he's had sex with at least one man before. But he was topping, so it doesn't count. Yes, yes, it sounds ridiculous, but think about it! Asses and assholes are gender-neutral. Everyone got one. Ergo: Fucking someone's ass isn't indicative of one's sexuality. Besides, it only happened once. Astolfo's gender is a joker, so sleeping with Astolfo doesn't count either.

Ermh. Anyways. Point is: Ritsuka may be a perfectly heterosexual man, but he's also very open-minded. He's perfectly capable of sucking his girlfriend's dick. His plan from now on is very simple; take her in his mouth, cherish her for a while, and when she's breathless and begging he'll climb on her lap and-

wait. No. He'll get her on his lap and fuck her. That's how it goes. Not that there is anything wrong with pegging, but it's just- not his thing. Certainly, he's had a couple stray thoughts, about Fergus- but it was curiosity, and nothing more. He would never enjoy taking it up the ass. He knows that because he's straight. A straight guy can top other men, or a straight guy can get topped by women, but both at once? That's not a straight guy. And he's straight. So he knows he wouldn't like that.

"Ritsuka?"

Okay. Okay okay okay. Focus. Once more, with clarity: He's going to suck her dick. He's going feel that throbbing meat against his tongue, fill his mouth with heat, and he is not going to think about how it'd feel inside of him, about the snap of her hips, about how she's look above him, sweaty, flushed, with that rare grin she wears whenever she's struck by confidence-

"You still with me buddy?"

"I think I'm a bottom?" He replies on autopilot, then immediately bites his tongue. Fuck. Fuck! Not what he meant to say! Not what he meant at all! Damage control, damage control! "I- I meant I'm bisexual." NOT LIKE THAT!!! "I meant- erhm, I meant-"

Artoria blinks, then properly sits up. "Do you... want me to fuck you?"

"No!" He responds, with enough force to make her startle. Her fairy eyes widen, pupils shrinking into slits like that of a cat, betraying her inhumanity. "I'm not- I'm straight. I'm straight."

"I... have no idea what this means."

Fuck. Right. Fairy. How the fuck is he supposed to explain to her the intricacies human sexuality to-

Suddenly, a hand seizes his collar, and effortlessly, Artoria flings him off the bed. Ritsuka tumbles, sits up, then seethes, setting his hands back on the edge of the bed. "Girl, what the f-"

"Bend over."

Two words, and his mind becomes full of statics. For a second, he stares at her, as if he expected her to backtrack, to laugh it off- but she does nothing of the sorts. When it becomes clear that he heard her right, Ritsuka swallows hard, and

bends

over

the bed.

Arms spreads on the sheets. Knees on the ground. Ass in the air. Like an obedient little bitch.

"Well. That was easier than I thought."

"I-!" He tries to raise his head again, snap at her that she was the one who ordered him around- but fingers lace in his hair, almost tenderly, before slamming him right back down on the sheets. His dick jumps at how easily she can manhandle him. His face is burning.

"Shush. I don't know what the issue is, but I think you're way overthinking this." Her fingers move, petting the top of his head; a gesture that is equal part comfort, and display of power. "You want me to fuck you. You don't have to say it. Just... let me take control for a bit?"

There's a light tremble in her voice, the one sign that despite her choice of word, she's not fully confident in what she's saying. If he speaks up now, she'll back out, and never bring it up again.

He bites down on his pride, shoves his face in the sheets, and mutters: "...A-alright... Master?"

Above him, he hears a sharp breath, the kind he normally only hears when he hits her most sensitive spots. Oh. Oh he's going to get it.
