Dean’s not even sure what they’re fighting about anymore but it was probably something big that got pushed down and down until something small cracked the surface and everything spilled over. Fighting always leads to great things, though, like Cassie’s nail digging into Dean’s scalp, sending pricks of pleasure-pain through him. Her mouth is hot and wet against his and he wants so badly to push her to her knees but he’s not in charge here. He never has been when it comes to Cassie and that knowledge makes his cock twitch where it’s still trapped within the confines of his jeans.
She pulls away abruptly, one hand under his jaw and the other gripping the back of his neck to hold him in place. Her eyes are dark and dangerous, and Dean’s breath catches.
“Strip and get on the bed.”
“Yes, ma’am.”
She releases him and Dean staggers back, landing hard on the mattress when his legs hit the edge. He looks up to see Cassie watching him expectantly, one brow raised. That’s enough to get him moving. T-shirt, jeans, and boxers are all tossed toward the hamper.
With Dean suitably occupied, Cassie moves around to the other side of the bed and Dean hears the telltale sound of her toy box sliding across the floor. He shivers, bent over to pull off his socks. When he turns to climb up onto the bed, he’s greeted with the sight of Cassie’s strap-on harness neatly arranged on the bedspread while she strips.
Dean settles onto all fours and is rewarded with a murmured “Good boy” for his initiative. He keeps his eyes locked on the bedspread, though he really wants to peek.
Finally, the mattress shifts behind him with Cassie’s weight. Dean’s breath quickens and he feels a little ridiculous about how turned on he is. She hasn’t even touched him yet but his cock is throbbing between his thighs.
Despite knowing it’s coming, Dean still startles when Cassie’s hands land on his ass. It’s not a smack, just her palms settling on his skin, but he still jumps and shivers.
“Settle.”
Cassie’s voice slides over him, leaving no room for him to argue further. He doesn’t know who “won” their argument but if anyone asks, it was Cassie. Always Cassie.
He didn’t see the dildo Cassie picked out but the weight of it against his tailbone when she leans against him is solid and he’s pretty sure it’s the big blue one with the nubs that drive him crazy. Cassie grinds her hips forward, letting the toy run across his dry hole, and this suspicion is confirmed immediately.
“You drive me fucking insane,” she says, low and filthy as her fingers curl around his hips. “If you’re going to act like a brat, I’m going to treat you like one. You know what that means, don’t you?”
“I don’t cum until you say,” Dean answers obediently, quickly tacking a “ma’am” on the end when he realizes he forgot. She doesn’t call him on it, thankfully.
“See, you can listen. I never would have guessed.” Her palm strikes hard across his ass, a crack in the quiet of her little studio apartment and a stinging pain that goes right to his dick. “Get the lube.”
Dean stretches to grab it from the top bedside drawer without shifting too far from his chosen spot. He returns to his position, bringing one hand around to rest in the small of his back and offer up the lube. She accepts it without a word. He hears the snap of the bottle opening and closing. The substance is cold when dripped from her fingers to his hole but Dean suppresses his shiver.
Cassie’s fingers are slender and he easily takes two right away with minimal burn. A groan pulls itself from his chest and his head drops between his shoulders. When he looks back beneath his body, he can see Casse’s skinny knees between his spread ones, and there, impossibly blue against the silky-smooth skin of her thighs, is the exact dildo he’d guess she grabbed. It’s about the same size as his own hard-on, a fact that makes his dick twitch and his body clench around Cassie’s fingers.
“Relax. Let me in.”
Dean takes a deep breath and nods, tilting his hips to invite her deeper. Her fingertips stroke just above his sweet spot and his eyelids flutter.
“Cassie, please-”
“Hush. Not yet.”
Groaning, Dean falls silent and listens to her murmur of praise. He hears the lube open again. When it snaps closed, the filthy wet sound that follows can only be Cassie stroking her cock. A third finger pushes past his rim, twisting deep and purposefully avoiding his prostate, and Dean makes a soft noise of complaint at the teasing but doesn’t protest past that. If he wants to get her cock inside him at any point tonight, he has to be patient.
Luckily, Cassie isn’t going to make him wait too much longer. “Pretty,” she’s saying softly. “Think you’re ready for me?”
The prep was quick but Dean is relaxing further into submission with each pump of her hand and he knows he can take her.
“Yes, ma’am,” he answers, stumbling over his words when her middle finger finally skates over his prostate.
“Beg me for it.”
Dean bites back a whine at those words. Spoken so calmly, like Cassie doesn’t have three fingers knuckle-deep in her boyfriend’s ass. He doesn’t know how she stays so calm when he’s falling apart beneath her hands.
“Please.” The word is barely more than a whisper, pulled from him by her pulling her fingers free. His body clenches around nothing, hungry for something more, and something in him cracks, desperation slipping through. “Cassie, please, I want - I need you cock. Please, fuck me. I’ll be so good for you, I’ll do whatever you want-”
“Shhh.” The hard silicone of the toy presses against his fluttering hole, not pressing in yet but the promise is there. “Shoulders down.”
Dean obeys without hesitation, dropping his chest to the bed and pillowing his head on his folded arms. His back arches and he feels so exposed like this, ass in the air with his girlfriend’s lube-slick strap-on teasing his entrance. His cock throbs at the thought of the sight he must make.
“You should see yourself,” Cassie says, wiping her hand on the sheets and running it from the center of his shoulders to the small of his back, then up again. She presses her palm right between his shoulder blades. She’s so small that he could push her off easily if he wanted to but he doesn’t want to. The weight of her is solid, reassuring and steadying him as the fat head of her cock pushes past his rim.
Dean lets out a breathy sound he’ll deny later, fingers digging into the sheets beneath his head, and Cassie sinks in nice and slow. She takes her sweet time, letting him feel every bump and ridge of the fake cock. It splits him open wide. By the time her narrow hips meet his ass, Dean’s sure he can feel the toy in the back of his throat.
“All the way in.” She curls over his back, long curls falling around her shoulders to tickle his back. “No one would ever imagine, would they? That big, bad, leather jacket-wearing, muscle car driving Dean Winchester takes my cock so beautifully. But you do, don’t you, Dean? You’re terrible at listening but this, you’re good at.”
Dean can’t respond. He’s too busy focusing on his breathing and the tightening of his balls. He can’t cum. He’s not allowed to.
“Doing such a good job.” Cassie sits up and palms his ass, spreading him further for her hungry gaze before she pulls back and slams in deep. “Gonna make sure you’re walking funny tomorrow, Winchester.”
They may not be great at this relationship stuff but Dean knows Cassie keeps her promises, especially ones like that. Sure enough, she barely gives him time to adjust before she starts fucking him hard and fast. Dean’s face burns and his mouth hangs open as he’s rocked by each thrust, the breath knocked from his lungs by each drive of her hips against his body. She’s small and strong, well-practiced at fucking shitty boyfriends the way they deserve and Dean knows he deserves it.
She knows he loves it.
“You can cum,” Cassie purrs, sliding her hand up his neck to grip a handful of his hair and yank his head back. He’s started letting it grow out a little and this is a definite upside that he decides in that moment. “But you have to do it on my cock.”
Oh, yeah. That’s not going to be an issue at all.
--
“We were always pretty good at fighting,” Cassie will say further down the road, when they’ve parted ways and found their way back together temporarily. When they’re pressed together in bed, naked inside and out, finally saying the things they should have said long ago but never did. She’ll gesture to their bodies and continue with, “This we were good at.”
Fighting and fucking, Dean will think and know she’s right. She may be the first person he’s opened up to outside of Sam but that doesn’t mean he was ever very good at it. Neither was she, for that matter.
Fighting and fucking, though. That they can do.
