robby looks out for santos, santos calls robby on his shit, and they both rely on each other to keep them sane. over time, they deflect their way through so many heartfelt talks that collectively they even manage to have a few.

So when Santos decides she wants to have a baby but can't afford to do IVF, Robby is the only guy she feels comfortable asking to knock her up.

Robby is completely blindsided, of course, but still flattered that Trinity feels comfortable asking him for something so personal. He offers to pay for her IVF instead, but Santos absolutely won't accept that much money from him.

She tells Robby she doesn't even want him to do child support or anything; she just wants to have a baby and she wants him to contribute the material do that.

They go back and forth about it for months — Robby trying to find any way around it, Santos not budging — until Robby finally caves and they reach an agreement: They will try exactly once to get Trinity pregnant. If she doesn't get pregnant after that one time, then she has to accept Robby paying for her IVF.

Trinity isn't thrilled, but it's better than nothing. Plus, she's spent the past few months meticulously tracking her temperature every morning in preparation, so she knows exactly when her next ovulation will be. So, with any luck, she won't have to let Robby shell out all that cash for her at all.

The night it finally happens is incredibly awkward. Robby’s so in his head that he’s has trouble getting hard, so Santos reluctantly agrees to help jerk him off.

Except, as soon as Santos wraps her fist around him, Robby gets so suddenly hard that he has to ask her to stop so he doesn't come before they even get started.

Then, when Robby tries to push inside her, she's still far too tight, so he offers to return the favor.

Santos says it's fine. If she needs a warm up she can do it herself, after all, but when she yelps and hisses as he tries to push in again, Trinity caves and lets her boss slip a hand down between her thighs.

Robby isn't the most talented set of hands Trinity's ever had down there, but for some reason her body is responding like he is. When she suddenly moans involuntarily, they both freeze.

Trinity quickly pulls his hand away with a mumble about being ready while she pointedly doesn't look at him.

When Robby lines himself up again and pushes inside her, they both choke around the groans that catch in their throats.

His cock slides in so effortlessly that their bodies fully slot together in one fluid motion, aligning with each other’s angles and curves like puzzle pieces.

When Robby begins to move, they both look anywhere but each other as they fight back the moans threatening to spill from their throats. Their hands twitch at their sides as they try not to touch each other anywhere except where their bodies are joined.

When Robby's pace speeds up, they both reach up to bite their fists at the same time and their eyes suddenly lock onto each other. Despite how badly they both want to look away, neither of them can seem to do it. They're trapped, staring in pained lust at each other as they pant and groan around their fists while Robby drives himself into her.

When robby's arm starts to shake and he shifts down to his elbows, the change in angle makes Trinity cry out. She stares open mouthed into her boss's suddenly closer face and, before either of them can think twice, their mouths and bodies crash into each other in frantic clasp of limbs.

Robby and Santos groan freely into each other's mouths as they lick and suck and bite the lips in front of them. Their hands twist into hair at the nape of the other's neck and Trinity's hips buck up against Robby's until their skin slaps viciously with each thrust.

Trinity's hands suddenly grip around Robby's rutting hips and hold them to her, and they both choke out matching groans as their bodies begin to piston together in shallow, lightning fast thrusts.

When Robby finally shouts and slams his hips firmly between her thighs, Trinity's eyes fly wide as her own unexpected orgasm roars through her. Their hands scramble to find purchase against the each other's flushed and trembling skin as they gasp and cling desperately to each other.

Neither of them remember falling asleep, but Robby is gone when Trinity wakes up.

When Trinity's test comes back with a definitive "pregnant" they're both thrilled. Yet, also strangely disappointed.

They both knew going into this that it would only ever be a one time thing and it's not like they found each other attractive, so why did they find themselves staring at each other across rooms or waking up gasping at the memory of the other's mouth and hands on their body?

As the months go by and Trinity's body swells with Robby’s child, neither of them mention how that came to be.

Which is probably just as well.

but since it is so late at night after such a long and draining day, robby doesn't enlarge the images or even grab his reading glasses off the night stand. he just slips a hand under his blankets and gets right to work on his nightly pre-bed routine.

he starts by vividly imagining snapping those thin panty straps against her hips and speckling little pink marks across her skin with the sharp, stinging snaps. he imagines that maybe she yelps or giggles a little when he does, and his responding smile crinkles the corners of his eyes.

he imagines how soft her skin would feel if he slipped his hands under the cups of her bra to tease her nipples with his thumbs, then imagines how warm and wet she might feel if he pressed his hand to the pretty fabric between her thighs and circled the pads of his fingers over and over until she started to squirm.

he imagines how her breath might hitch if he pulled her panties to the side and rubbed himself across her lips, how her skin would be all flushed and glistening as he traced his tip between her folds. he imagines squeezing the soft flesh of her hips as he pushes forward and rocks himself inside her — slow and steady, at first, then gradually harder and faster.

he imagines holding her hips in place as his thrusts speed up, thighs slapping against hers again and again, until finally he can't take it any longer and he suddenly pulls out, panting and jerking himself fast and hard until he cums all over that perfect, pretty lingerie on that perfect, pretty girl.

robby collapses back onto the bed, phone forgotten as he luxuriates in his post-orgasmic haze. his head buzzes and chest heaves as waves of endorphins and visions of soft skin and pretty lace wash over him.

then, as his pounding heart rate slows, robby realizes with a chuckle that he never actually tapped in to really look at the photos.

with a grunt, he rolls over to reach for his reading glasses and, when he slips them on, he re-focuses his blinking eyes on the screen as he finally taps into the photos. as the larger images fill his screen, he frowns, then zooms in on the young woman's face and–

robby tumbles out of bed and lunges towards the bathroom, making it just in time to become violently, wretchedly sick.

after he finally stumbles back to his bed, robby lies awake for hours, staring at the ceiling. the rock of guilt in the pit of his stomach becomes heavier and more solid by the hour, until it's almost as heavy and hard as his cock still is.

almost.

but no matter how many different ways he tries to will it all away, robby can't stop thinking about how good and right it felt — to imagine touching and teasing and fucking… her.

by the time he finally wakes up the next morning, groggy and miserable, robby sees that his daughter unsent the photos and replaced them with an innocent meme instead. she didn't mention sending him the wrong pictures so, after a bit of consideration, robby decides he doesn't need to mention that he saw them.

or that he saved them to his phone. ____

obviously any type of dad/daughter robtoscest where they know they're related or don't is always going to be the top of my list. bio, step, foster, whatever. genetic arousal or learned arousal, either way. just them being dad/daughter and fucking for some circumstances is always a hit for me.

i also just like them hanging out and joking around as dad/daughter too. they have similar senses of humor and i think they would just kinda "get" each other in a way other people don't. mixing in this type of banter into sex or physical intimacy is obviously also great.

my mini fic about trinity wanting robby to be her sperm donor was fun too and I could totally use more of that, either with the unknown incest element or not. i just like the idea of trinity looking at robby and going, yea, that'd be a good dad for my kid (cuz he's already a good stand-in dad for her)

i also like trinity using robby as a means of "exposure therapy" for combating her past SA? like whether or not she's into men herself I like the idea of her just sort of using robby as like a "safe" man she's allowing in and changing the narrative so that she's the one choosing to engage and in control. robby of course is skeptical but eventually willing to help (and then loves it so much he feels like a horrific pervert <3 <3)

any kind of fuck or die situation (sex pollen, omegaverse, etc) is also so fun and I'd love to see that with them, especially with the dad/daughter element. the guilt/disgust paired with the reluctant but strong arousal from them both would be delicious. i think robby being an omega and santos being an alpha would also be really really fun. maybe jack goes on vacation so robby doesn't have his regular heat partner and santos finds him and has to take care of him.

i would also love to see them in a fake dating situation but i have no idea how we could get them in one. but the sheer awkwardness of the two of them about it would be so fucking funny.
