So Eren speeds up just a bit more, rocking his hips with just a little more vigour, and keeps talking.
"Good way to shut you up, too. Next time you annoy me I'll just feed you dick and watch you forget all about what you were bitching at me for..."
It's a sign of how far gone Jean is, how much he enjoys all of this, the feeling of Eren fucking into him as much as the dirty words, that he doesn't reply with some kind of indignant grumble. Eren is pretty sure that should he ever even try anything like that during an actual argument with Jean, his loving boyfriend would punch him in the dick before sucking it and honestly, he would deserve that. But here, now, having Jean bent over the couch and whimpering, it is a fun little fantasy that makes Jean's breath hitch and his ears flush.
Eren huffs a little laugh at the sight before shifting his weight. They both still need more and he needs to change it up a bit if he really wants to give his boyfriend what he is craving. So Eren slows down just long enough to plant a foot on the couch. The surface is a little unsteady but still gives him the leverage he was looking for and his next thrust is hard enough to make Jean's teeth rattle.
His boyfriend gasps a passionate curse. Eren does not allow him to catch his breath before giving another thrust, yanking Jean's hips back against his own.
"Turns you on, huh?", he asks, his own voice becoming a little more breathless as well as he keeps up the pace, giving it to Jean good and hard. "Thinking about just opening your mouth and allowing me to stuff it. I'll make it so easy for you to give in, too. Just grab your hair and push this dick between your lips, not even giving you a choice…"
Another curse that doesn't even sound English anymore, the few syllables drawn out and needy and Eren groans with want. Whatever he is doing that is working, he will keep going. Jean is way too gorgeous when he's babbling in French, his voice taking on a higher note, something airy, almost whimsical in his voice when he falls back into the quiet, melodic sound of his mother tongue.
"Love it when I make you kneel and use you, hm? Make you get me off without caring if you like it or not..."
Of course Jean always, always likes it, way too horny most days to even think of struggling, always immensely enjoying it when Eren gets rough with him. Just like now that he is whimpering and crying out, stuttering pretty French curses as Eren pounds into him, running his mouth like he is getting paid for it.
With a wicked grin Eren shifts his hand, letting go of Jean's hip to instead reach up and bury his fingers in Jean's soft hair to grab a good fistful. He yanks Jean's head back, hard, and strains to lean forward until he can hiss into his ear.
"Fuck, Eren..." The breathless curse is strained, voice tight like it always gets when Jean is close, so close to coming but can't just yet. He must have been even more wound up from sucking Eren than expected. But still he can answer after a few, desperate gulps of air.
"Love it..." the words are low, slurred and absolutely gorgeous with the soft lilt sneaking into Jean's voice. "Love it when you ... fuck, when you use me..."
Eren hums in appreciation, lips brushing against the flushed shell of his boyfriend's ear. But before he can decide if he wants to sink his teeth into the tender arch or if he wants to whisper hot praise Jean continues. And he is begging.
"Eren ... Eren please I'm ... g-god I'm so close ... P-please touch me ... please..."
Eren feels his cock twitch and throb, excited, needy wetness seeping out of his clenching slit. Fuck, that is hot. And he didn't even have to make Jean beg for it, his boyfriend just went for it all on his own...
With a low, needy noise he closes his teeth around Jean's ear and lets go of his hips completely to sneak a hand around. He shudders with delight when his fingers close around the straining length he finds. It's so hot, painfully hard between his fingers and slick with steadily dripping precome. Eren bites down on Jean's ear the moment he flicks his wrist for the first time, rubbing his palm right across the sensitive tip that is so wet under his touch he grunts again in pure delight.
"Eren!", Jean gasps at the movement that must be almost too cruel and Eren does it again, times it with a deep, rough thrust.
Usually his greedy boyfriend needs more but this time he is so wet and hard and desperate, groaning and gasping and cursing at every torturous touch of Eren's hand, maybe he can be pushed over the edge just like that. Just with their favourite toy shoved deep into him and Eren's palm rubbing across his tip.
He is pretty sure the next thing that comes out of Jean's mouth is some kind of insult but then his entire body shudders and he tenses up in Eren's arms and the next thing Eren knows Jean is coming all across his palm and fingers, sticky come dripping down onto the couch while Jean curses and moans and babbles beautiful French syllables.
Eren fucks him right through it, not needing to chase his own high yet so he makes sure that his boyfriend is getting just what he needs out of this blinding, torturous orgasm.
Even when Jean's body goes limp, slumps over the back of the couch, Eren keeps going, smooth, deep thrusts that shake his boyfriend's flushed body.
It's only when Jean reaches back to tap his thigh with clumsy, limp fingers that Eren starts to slow down. Finally letting of both Jean's hair and his sticky cock Eren rubs his clean hand down his boyfriend's spine, a slow, soothing motion that makes Jean hum so sweetly.
After a few more moments during which they slowly start to catch their breath Eren licks his lips, shifts his weight so he can stand on the ground again.
"You good?", he asks, his voice low, almost secretive as he drags his fingers across warm, sticky skin. God, he loves the post-coital glow on Jean.
A pause, then a slow nod as Jean sighs deeply, his body relaxing even more into the couch.
"Yeah, that was ... ugh Eren, that was amazing."
"I noticed", he grins back and can all but feel the way Jean rolls his eyes but doesn't comment on it any further. So Eren begins to pull out, wrapping his sticky fingers around the base of the toy and moving especially slowly as to not hurt Jean's sensitive opening. He hasn't even finished completely when Jean peeks over his shoulder, eyes sparking through the tousled hair that falls into his face.
"Want me to return the favour?", he echoes Eren's words from earlier and Eren can feel himself twitch behind the leather straps of his harness. He'd known it would be a long night. And he couldn't be more grateful.
