You can’t pinpoint exactly when he stopped being Uncle Robby and started being just Robby to you. But you can pinpoint the exact moment he stopped being Robby and became Michael, oh god, fuck, don’t stop. Your dad, Jack, had been planning to take you on a week-long trip to California for your 25th birthday, hating your best friend’s idea of a drunken singles cruise from Cancun and promising to think up something better if you didn’t go.
Then he’d come down with the worst case of food poisoning in his life the day before you were supposed to leave. You suggested going by yourself, but that idea made his protective instincts roil. Then you suggested canceling the trip altogether, but that made him feel so guilty he threw up again. Finally, you wracked your brain for someone your dad trusted as much as himself and pitched, “How about I ask Robby to come? He’s got tons of vacation time saved up since he, y’know, never relaxes.”
Your dad groaned into the toilet bowl, “He’ll never go for that on short notice.”
Jack, of course, was unaware that your friendship with Robby had turned into something different since you moved back to Pittsburgh after your undergrad and master’s across the country. Not crossing any lines yet because you both knew how wrong it was and how much it would get under Jack’s skin, but there was definitely flirting. Touching. Smiling and laughing. Late night phone calls and casually bringing him a second lunch at the Pitt when you stopped by to see your dad.
So, when Robby agreed to ‘chaperone’ you through Malibu, Jack was too sick to question his motives. But the two of you didn’t even make it through the first night after watching the moon rise up over the white sand beach.
“We shouldn’t do this,” he murmured as he fiddled with the tie at the side of your bikini bottoms in your shared hotel room, trying so hard to muster the conviction of character not to give in. But he kept coming up empty. Weak. “I really, really shouldn’t do this.”
“Then you should probably stop me from taking my top off,” you teasedsoftly, reaching behind your back and slowly pulling the string behind your neck. “Last chance, Michael.”
His resolve shattered.
And he didn’t regret it. Not by a mile.
Now it’s been nearly a year of being together. At first it was mostly sex, both of you promising that this would be the last time into the other’s mouth each and every trip to his apartment or yours. But, slowly, it became a lot more than that. He started holding you closer. You called him more often. When he tugged you into a supply closet, half the time he just wanted to talk to you. Your clothes migrated into his dresser and you slept in his bed even on nights when you didn’t fuck.
Then you got laid off from your job. The unspoken tension of your two choices had created an untenable situation: You could move in with Robby, admitting your relationship out in the open with a hard launch, or you could move back in with your dad and try to keep it a secret as long as you could. As much as Robby assured you that he was ready to deal with Jack’s wrath and call you his, you weren’t sure you were ready. And he respected that.
It finally reaches the moment you’ve both been dreading when Robby’s apartment needs to be fumigated. Jack, of course, offers to let him crash on the couch for the 72 hours it’s going to take, thinking nothing of it. Robby knows he won’t be able to resist fucking you if it’s just the two of you and your skimpy pajamas, so he says he’ll get a hotel only to be met with a jovial ‘come on, let me do something for you, you’ll be happier eating her cooking anyway.’
Robby and you both swear you won’t fuck while he’s there. You’ll be perfect angels and then have a total fuck fest once his apartment is ready.
That lasts all of about ten seconds.
You answer the door in the tiniest sleep shorts he’s ever seen and an old camisole that’s basically see-through, your nipples perking up as the cool spring air breezes into the house. Then there’s that sappy, starry-eyed smile you always give him when you haven’t seen each other in a couple days.
“Fuck, baby.” He pushes you back by your waist, drops his back on the floor, slams the door, and pulls you into a bruising kiss. You giggle into it, knowing he must’ve already seen your dad at work on his way out if he’s being so brazen. “Missed you so much. So fucking stupid thinking I could resist you for even a minute,” he mutters as he kisses down your neck, pushing you toward the staircase and then just hiking you up into his arms when your step falters.
You loose a laugh as his hands cup your ass and the small of your back. “Carefully, Michael, I don’t want you to hurt yourself.”
“I go to the gym with my girlfriend five times a week,” he reminds you as he ascends the stairs confidently, beelining toward the bedroom he helped you paint yellow when you were sixteen. As he flops you down on the bed, “She keeps me young. I’ve gotta be able to throw her around like she needs.”
You raise your eyebrows and cheekily tug your top over your head before leaning back on the pillows. “What else does she need?”
“She needs to stop teasing me,” he chuckles, dropping down to push his arms on either side of you and kissing you hard. One hand goes up to pinch and roll your nipples until you arch your back and greedily moan for more. “God, you’re gorgeous when you’re needy.”
“Haven’t seen you in three days,” you groan as he gives up on being patient and pulls down your little shorts. He kisses down your torso and thighs. You hiss in a sharp breath and whimper, “Missed you so much. Need you.”
“Yeah? You need me?” He stands up once he has you naked and strips himself hastily. His cock is throbbing and his pulse is pounding and his ears are whooshing, all with the lust and desire to have you, his perfect girl, again. Every second without you is agonizing. It really does make him feel like he’s a teenager again, not just horny all the time but heart-skipping, cheek-reddening, all-consuming crushing on you. It’s love now, for sure, but it still feels fluttery and sweet. Fisting his cock as he grins possessively down at you, he orders, “Show me how much you need me, baby.”
Eyes roving all over his exposed body – his wiry chest hair, his muscular thighs, his ridiculously big hands – you spread your legs for him. You watch with unbridled delight as his pupils dilate and he starts to stroke himself faster as he realizes you’re already soaked. For him. Always just for him. “I’m ready, Michael, don’t make me wait any longer.”
He sighs and tugs you to the end of the bed, lining himself up with your entrance. “You knew I was gonna walk in that door and fuck you right away, didn’t you?”
“And you knew I was gonna beg for it,” you whine back and roll your hips to encourage him.
He toys the head of his cock through your wetness a while first, playing with you just so he can see you squirming and whimpering. “You’re pretty when you beg.”
You bat your eyelashes innocently at him, lock your legs around his hips, and almost force him to thrust into you with your thighs. “Please, babe, need your cock already. It’s all I think about when I’m turned on. Give it to your girl.”
That makes him growl under his breath. He shoves inside of you in one sharp thrust that steals your breath away. Then he bends down, threads his fingers with yours, and kisses you deeply. His free hand goes right to your clit; you’ve been together long enough now that he knows exactly how to get you off, his fingers finding that perfect pressure and pace to match the pushes of his cock. He noses up your neck, gradually kissing and sucking and scraping his teeth until he feels your pussy walls fluttering from the added attention. “My girl. Mine. Love you so much.”
All you can do is whimper in response. You nod into the crook of his neck and shoulder as your chest and cheeks turn hot. He squeezes your hand to ground you and you open up your eyes to meet his at the protectiveness and intimacy of the gesture. Your free fingers twine in the hair at the base of his neck and you murmur, half-gasping from the force of his thrusts, “Love you, too.” Then you tug his lower lip with your teeth and moan, “Deeper. Harder.”
“Good girl,” he praises, pulling out only long enough to flip you over. With you on your knees, he shoves down the small of your back, gets your ass high in the air, and smacks your flesh. The sting is enough to make you gasp and it shoots pleasure straight through your cunt. He watches your pussy clench around nothing and smacks you again. His voice is rough and gravelly as he says, “That’s my baby. Taking it all so well.”
You plead out, “More, Robby. Gimme more.”
Robby laughs sharply at your eagerness that makes precum drip from his dick. He thrusts back inside your cunt and pounds you once more as his hands rain down on your ass, the slaps loud and painful and fucking perfect.
Neither of you hear the front door opening, too lost in shared ecstasy. Jack doesn’t even close it, just popping home to grab something he left on his bedside table, but the sounds coming from your room stop him in his tracks.
The blood drains from his face.
Robby’s car is out front.
Jack shoves the door open and sees a horror movie playing out. His baby girl, tears streaming down her pink face. His best friend smacking her ass hard as he drives into her. His vision goes white. Jack yanks Robby away from your bed and shoves him against the nearest wall. As you frantically tug on clothes, you hear the thud of Robby’s head, followed by your dad’s fist colliding with your boyfriend’s jaw over and over. “What the fuck are you doing? That’s my goddamn daughter and- Fuck, I’m gonna kill you.”
“Jesus Christ, dad, stop!”
But Jack doesn’t relent. His hand around Robby’s neck pushes in harder and panic rises up in your throat. His other fist drills into Robby’s gut. “Can’t believe you’d take advantage of her like this. Fucking disgusting old man might as well be-”
“Stop it!” You lunge toward them and scramble for your dad’s strong shoulders, shrieking out, “Don’t hurt him! God, he’s not just fucking me; we’re- we’re together. We’ve been together for a year already and you’d better stop or I’m gonna jump out that window right now!”
“Wait, what?!” Jack whips around to you and Robby takes in a deep, wheezing breath now that he’s out of Jack’s grip. “You think you love him? That man changed your diapers, princess, you can’t- he can’t-” He looks over at Robby in disgust and rage and growls, “Mind getting the fuck out of my house now?”
Robby croaks, rubbing his bruising neck and wondering how he’s going to explain these particular marks at work, “Can I at least put on my clothes first?”
Through the red haze of his anger, Jack remembers Robby’s naked and stares at the ceiling lights while his insides twist. It’s like he’s in a nightmare. At the next horrific realization, he retches, “Fucking hell, you’re not even wearing a condom.” Jack doubles over like he might throw up, sounding panicky and pissed. “Please tell me you’re on birth control, sweetheart. God, when did you get on birth control? I’m a doctor; why wouldn’t you tell me that-”
“Dad, try to take a deep breath” you murmur, reaching out to touch his back. “You’re gonna have a panic attack. Or a heart attack. Try to calm down.”
“Calm down?” On the verge of hysterics, he gestures between you and Robby. “I just found out that my best friend, a man I’ve trusted to watch you since you were an infant, is a fucking pedophile.”
“Woah, dad, Jesus! Way too far!”
“What else do you call a-”
“Man who is in a serious relationship with an adult who has a fully developed frontal lobe? I’d call him a perfectly normal person.” You tap your chin sarcastically and prod, “Hm, I wonder if there are any other men in their forties here dating girls in their twenties.”
Robby flinches at that. It was an inevitable weapon in the arsenal, but still.
Jack scoffs at the accusation and replies, “Samira is a doctor and-”
“And your subordinate,” you push back, “and only two years older than me.”
“I never babysat her.” Pale and sweating, he demands, “When the hell did this start, anyway?”
“It wasn’t like that, dad, I swear to god.” You cross your arms over your chest and sigh, “We got close when I moved back to Pittsburgh two years ago. And then we actually started, y’know, seeing each other during the trip last summer.”
He rubs his hands over his face. “Should’ve sent you to Cancun. At least then you’d be fucking some drunk asshole instead of-”
“A kind, respectful, successful doctor?” You poke him in the chest and say, “I could do a hell of a lot worse. Already have, in case you forgot.”
Finally, Jack turns to face Robby. With a deathly quiet voice and unreadable military features, he orders, “Your turn. She says it wasn’t like that, so you’d better tell me what it was like. Timeline. Now.”
Robby still seems like he might pass out or puke at any second, but then he looks over at you. So fast Jack doesn’t even notice, you give him an encouraging smile. It’s time for him to fight for you, not shrink back. “Try to think about it, Jack. She avoided me like the plague during high school because I was too lame for her, obviously, and then I never even saw her until she finished her master’s and moved back here. I mean, I hit on her at a bar before I even knew she was back in town. I thought she was a total stranger. Didn’t even recognize her since she switched to contacts out in California.” He rubs the back of his neck and sighs. “We just…we just got to talking. Neither of us thought it would be serious. But she’s brilliant, she’s funny, she’s beautiful, she’s every-”
Jack finishes his beer and grunts, “Of course she’s beautiful; she looks like my dead fucking wife, who would be horrified by this.”
You mutter, “Mom would’ve understand. Or at least she wouldn’t have hit him.”
Robby cringes and says, “Might not be the best time to bring up Rachel, baby.”
“You call her baby?” Jack scoffs and rubs his hands over his face. “That’s messed up.”
Robby rolls his eyes, which makes you smile just a bit. “She’s my girlfriend, Abbot, I call her all kinds of things.”
“Your girlfriend,” Jack repeats. “Christ.”
Despite the response, he seems calmer now. Not necessarily satisfied or accepting of the situation but no longer so worked up you’re worried about his cardiac health.
He takes a few deep breaths, still avoiding eye contact with either of you, just trying to calm his heartrate. As he pinches his brow, he scowls and says, “Okay, I- I have to get back to the hospital. There’s an multiple MVC coming in and I only came back to get my fucking badge reel.”
Robby tentatively says, “Sure you’re good to practice when you’re so-”
Jack snaps toward him. “I am one millisecond from shoving my titanium foot up your ass, Robinavitch, so you’d better stay fucking quiet.”
Robby hangs his head. “That’s fair.”
“We’ll all…wel’ll talk about this when my shift’s over.” Then he shakes his head and adds. “Just, fuck, please don’t do anything like that in my house again.”
Then, like the soldier he is, he turns out of the room, snatches up his badge, and heads out, cursing and muttering under his breath the whole way.
You and Robby don’t look at each other until you hear Jack’s car peeling down the street.
You’re the first to break the silence, standing up and trying to keep your tone neutral. “You’re bleeding; come to the bathroom so I can clean you up.”
With a reluctant nod, Robby follows you to your en suite. Jack had given you the primary bedroom when you’d moved into this house as a teenager because, as the minimalist single dad of a teenage girl, he didn’t want to deal with the guest bathroom being full of all your soaps and potions. Robby leans against the countertop, now, and you dab at the wound on his cheek with cotton and antiseptic like your dad had taught you as a kid. There’s more pain in your eyes than his as you carefully place a bandage over the small but deep cut. “He must’ve caught you with his wedding ring. I’m so sorry.”
“Nothing to apologize for,” he says with a shrug. “I think most dads would hit a guy if they walked in on him fucking their daughter raw. Especially considering the, ah, the spanking.”
“Good point.” You bite your lip and look up at him with teary eyes. He hates how scared and alone your voice sounds as you ask, “Are you gonna break up with me now?”
Robby sighs and guides you back to the bed, sitting down and patting the space next to him so the two of you can talk. “No, baby, I’m not. Do you want me to?”
“Definitely not.” You crawl into his lap and plant gentle kisses along the base of his neck, each one an apology for Jack’s harsh grip on his throat. “You’re it for me, Michael. Dad’ll come around.”
Carefully, Robby asks, “And if he doesn’t?”
You give him a gentle kiss, testing the waters, and whimper with relief when he returns it, hands going to your hips. When you pull back, you cup his unbruised cheek and offer up, “Well, I’ll make a really good roommate. I’m neat and I’m good at cooking. And I put out in exchange for rent money.”
Robby rolls his eyes and laughs, “You could be a total slob and I’d still want you to live with me. I love you. That doesn’t change now.”
