#i uh

This one, he likes. This one is much, much more handsome than anyone else his mother has managed to bring home. Good for her, he thinks. How'd you manage that, Mom? 

He's a doctor, and wow, that's so cool. It makes Dennis think … maybe I should change my major. Maybe, actually, I want to be like Robby. The man is kind, and interested in Dennis. He's not put out that his new girlfriend's adult son lives with her, is around most of the time. He'll sit at the kitchen table and explain what it's like working in an emergency department. He'll talk through procedures and what med school is like. 

Dennis is entranced. 

He's known that he's queer for a long time, but beyond some disappointing sex with boys his age, he's never really been that interested in fucking around. 

He realises, now, that going after boys his age was his mistake. Obviously, he needs a man. A real man, like Robby. Someone older and willing to teach him everything he wants to know. Someone with scruff and a bit of a belly, and crows feet and the faintest hint of gray in his hair. 

Why look for someone just like that when there's one right here, in his house? Someone perfect. 

His mother is delighted that Dennis likes Robby so much. Over the moon that she's finally found a nice guy that gets on with her kid. 

She has no idea, and Dennis has no plans in informing her. Does he feel a little guilty that he's lusting after his mother's boyfriend? Look, a little, but not enough to stop. 

Robby spends nights, more and more, over at their place. Dennis knows they're having sex, Robby and his mother. He can hear it through the walls sometimes. It's strange. He doesn't want to hear his Mom getting off, but damn, he sure does enjoy the sound of Robby's distant grunts and moans. 

If he touches himself imagining that it's him that Robby's fucking into, well. 

That's his business. 

It becomes standard, in the mornings, for Dennis to run into a half-dressed Robby in the kitchen. 

"Hey, kid," the man had said, sheepish, the first time. Dennis had shot him a flat look, and ate his cereal beside the man at the table. 

"Nice night?" he'd asked, innocent, raising his brows. 

Robby choked on his toast. 

Now, it's less awkward, and Dennis looks forward to it every time. Getting the chance to see Robby's bare chest, hairy and gorgeous and sometimes flushed. The shape of his belly, just poking out from under his sweats. 

Now that Robby is spending more and more time here, has all but moved in, he leaves clothes lying around. He has a drawer in Dennis' mother's room. When they're both out at work, Dennis sneaks in there and rifles through that drawer. There's plenty he could take, that he'd like to take - underwear, for one - but he has plans. 

The first time he walks around, lazily, in Robby's well-worn sweats slung low on his hips, he watches the way the man's eyes follow him around the room. Glued to him. A thrill runs down his spine. Yes, good, look. Look at him. See him. 

"Are those my - ?" Robby asks, but cuts off when Dennis looks over at him, all big eyes and sweet questioning face. 

"Your?" 

"Uh. Never mind." 

Robby moves in, formally, and now, they're together all the time. He's always around. It's hell and heaven. Dennis has an unending supply of the man he so desperately wants, and cannot have. Can't touch. It's torture. 

He learns the man's schedule. He starts early, way earlier than Dennis would ever usually be awake, but he can make sacrifices. He sets his alarm privately for 5am, and uses the quiet of the house, his mother still asleep, to peek through the sliver of the bathroom door left open so the room doesn't get so steamy. 

It's just the right amount for Dennis to have a perfect view of a nude, showering Robby. His mouth waters, every time. He thinks about just stripping off and getting in with him, seeing what happens, how Robby would react, but. 

No, he doesn't want to risk it. 

He rubs himself through his boxers, watching Robby wash every inch of bare skin, lather up his beard and rinse it clean. His cock, Christ. It's bigger than anything Dennis has ever seen outside of porn. It's thick, and hangs heavy between Robby's legs.

Jeez, Mom, he thinks. How are you taking all that? 

Then he kind of wants to rinse his mind clean. This is a mind-fuck. 

He snaps a few photos, through the crack in the door. They're not great, they're not awesome quality, but they're enough for him to jerk off to every night. A glimpse of thick cock and strong thighs and plump, juicy ass. 

His mother sits him down one evening while Robby's still at work. 

"Sweetheart, I need to talk to you about something," she says, serious, and his heart races. 

Oh, fuck, has he been caught? Surely not. She'd be losing her shit if she knew. 

"Yeah?" he asks, nervous. 

"Well, you know Rob and I have been together for a while now," she starts. She looks nervous too. "And - you like him, and I think that's just great. The thing is, he's - asked me to marry him." 

She looks so emotional. 

He feels a thrill of - something. 

"Are you gonna say yes?" he says, careful. 

She nods. 

"But, only if you're okay with it. I don't want you to feel like you're being excluded, or - well, he loves you too, and I think it would be so nice for us all to be a family," she adds. 

So does Dennis. 

"Of course I'm okay with it, Mom," he replies, warm, smiling. "He's a great guy." 

"And I know how you feel about having a replacement father," she says hurriedly. "He's not trying to be that!" 

Dennis swallows hard. 

"I don't know. He's nice. I'd be kinda okay with him being my Dad." 

She bursts into tears. He has to hide his boner. 

After that, it's easier to … plan. 

His mother joins the church choir, and she spends half her evenings at rehearsals. It leaves Robby and Dennis at home together, alone. 

Dennis lounges on the sofa, wearing the sweats he's never given back, and an old, nearly threadbare Placebo t-shirt he found in Robby's drawer. 

The man has never said another word about Dennis slyly taking his clothes. Wearing them in plain sight. But he does look. A lot. 

More often than not, Dennis can feel the man's eyes on him. He stops wearing underwear. Lets the sweats sit lower and lower on his hips, so the very top of the line of his ass is visible. Just a peek. 

He knows he's a certain type of hot. Young, lithe, sweet. He plays it up. 

"Shouldn't you be out with your friends?" Robby asks him one night, when they're both sitting on the sofa, watching the Penguins get demolished. "It's Friday night." 

He shrugs. 

"I'd rather be here. With you," he says sweetly, and gives Robby a sidelong glance. 

The man is just the tiniest bit flushed. 

"You're only young once," Robby tells him, not looking away from the screen. "You should be - out there, getting drunk and smoking weed and hooking up." 

Dennis laughs. 

"I mean, if you want to get me high?" he suggests with a smirk. 

"I am not getting my wife's barely legal son high," he drawls. 

Dennis cocks his head to the side. 

"I've been legal for two years, thank you. Interesting that you're thinking about it," he purrs. 

Robby goes stiff. 

"Anyway, you're married now. I thought I was your son, too," Dennis adds. 

It's maybe a step too far, because Robby goes red, and stands abruptly. 

"I gotta hit the head," he says, and disappears down the hall. 

Damn it. 

The next time, he's more careful about it. 

He lets some frat boy leave hickies up all and down his neck, before pushing him off before he could get into Dennis' pants. 

"Thanks, champ," he'd said, patting the boy's cheek and leaving him with blue balls. He'd got what he needed. 

When he gets home, his mother still at church, and Robby sees the litany of bruises, he pales. 

"What the - " 

His voice is a growl. 

Dennis widens his eyes. 

"What? I thought you wanted me to - what was it? Go out and hook up?" 

He's got a plug in. Has for hours. Opened himself up knowing that he was going to enact this plan tonight, just in case it works out and he can taunt Robby into finally, finally taking him. 

"You look like a whore, kid," Robby snaps. 

Dennis takes one step closer, cocking his head. 

"That's not very nice, Dad," he purrs. 

Robby's eyes flash, and then he's moving fast, shoving Dennis up against the wall hard and kissing him so viciously his teeth might actually pierce Dennis' lips. 

Triumph and desire course through him, and he moans, opening for Robby so fucking easy. 

"Fuck, yes," he breathes, and slides both hands under the older man's shirt. Finally, finally. He's warm and soft but there's nothing soft about the way he's forcefully yanking Dennis' jeans down, spinning him round so his face is pressed into the wall, smushed hard. 

"You little fucking tease," Robby's snarling into his ear, dark. Dennis might cum just from this. "You think I haven't seen what you've been doing? Parading around in front of me? In my clothes?" 

Dennis stands up on his toes to clench his ass better, and bends at the hips just slightly, offering himself up. 

"Took you long enough," he sighs, and moaning deep when Robby's fingers brush over the plug in his ass. 

"What the hell is this?" the man murmurs, but before Dennis can answer, it's being pulled out of him, merciless, and Robby's cock is grinding against his empty hole. 

"Fuck," he hisses, pushing his hips back eagerly. "Oh, God, please, fuck me." 

"You just make it so easy," Robby spits, and then he's pushing inside, cock slick with spit and lube from Dennis' leaking hole. It's still a hell of a stretch, a burn. It fucking hurts, but then, he bottoms out, and Dennis is so full he thinks he might cry. 

"Yes, fuck, God, Dad, fuck me, move, come on," he whines, and he can feel Robby's cock twitch inside him. He snaps his hips back and forward, hard, the force of it throwing Dennis back into the wall. 

"I am not - " Robby starts, but it cuts off into a low groan as he finds a rhythm, fucking Dennis rough and deep. 

"But - you - oh fuck - are," Dennis pants, his eyes rolling back in his head. "On paper." 

"You're fucked up, kid," Robby grunts, and Dennis can hear every bit of dark want in his voice. 

"No more than you," he counters, breathless. "You're fucking your wife's son, and loving it." 

Robby moans, and then Dennis' head is being pushed, hard, into the wall, his cheek mashed against it under Robby's large hand. 

"Been wanting this for fucking months," he mutters into Dennis' neck. "Fucking cocktease. Should have made you mine from the beginning." 

Dennis might be a young man -  young, dumb and full of cum - but he can't help the fierce wave of arousal and want and ohgodfuckyesplease that washes over him, coming untouched against the wall. 

"Yeah?" Robby sneers, still fucking into him so hard that Dennis' wobbling knees struggle to hold him up. "You like that? You wanted it too, didn't you? Wanted me to put you on my cock like a good boy and fill you up." 

"Yes, yes, yes, I told Mom to - to marry you so you wouldn't leave," he admits, panting hard. "So you'd be my Dad. So I could have you." 

Robby makes the most delicious sound he's ever heard, and then he's cumming inside Dennis, hot and filthy and hard. 

After that, Dennis keeps himself open and ready, every day, so Robby can drag him over the back of the sofa, the kitchen bench, push him onto his hands and knees on the bed and fuck him whenever he likes. 

People start to comment on how sweet it is that they have such a good relationship. They're so close. It's nice to see that blood doesn't have to be the defining factor of family. 

Dennis starts calling Robby Dad, and his mother beams with pride. Robby will throw out son here and there, and when they go out together alone, no-one knows they're not really father and son. 

His mother wants them to stay in one Saturday night, so grateful that her grown-up boy doesn't mind spending time with his parents still, and watch some movie she's been eager to see. 

Dennis waits until she's in the kitchen getting popcorn, and crawls into Robby's lap, sinking down onto his cock and facing the television. The man has to muffle his moan, hips bucking up before settling. 

"What are you - she'll see," he hisses, but Dennis just wriggles his ass until he's comfortable. 

"She won't if you keep your shit together," he whispers. He's just having a snuggle, with his Dad. Nothing wrong with that. He didn't have a Dad for so long, Mom, he's making up for lost time. 

She doesn't even bat a goddamn eye. They're both still fully clothed, and his mother's a modest enough lady that she leaves space between them on the sofa. Nothing too affectionate or improper in front of Dennis, after all. 

He's wearing loose shorts, because it's summer, it's hot, and he's just at home, it's fine. They're conveniently easy to pull to the side and let Robby push his cock inside. Hidden. 

Dennis laughs in all the right places throughout the film, and the movement gives both him and Robby a little shock of pleasure. He can feel the tightening of the man's thighs beneath him, the struggle not to fuck up into him. 

"You," Robby murmurs into his ear, very quietly, on the side his mother isn't on. "Are a filthy little boy." 

Told y’all my next one wouldn’t take so long. Also my first bingo! :)
