Anonymous asked you:love me river/11 with matt/alex
I really wasn’t sure what you meant by this prompt, or how to go about it… but woahhh I bet this wasn’t what you had in mind (sorry not sorry)
Behind the cut for nsfw
It had been strange (and that was an understatement) the first time they’d met their counterparts in the flesh, but Matt and Alex had come to accept that, impossible though it was, the Doctor and River Song (exact replicas of themselves, down to the last freckle) did actually exist. And how glad of it they were – if it wasn’t for them, they wouldn’t be together after all.
Still gasping from her climax, Alex smiles at this thought as she glances away from the couple across the room from them to look down at the ring on her finger as she cups her hand to her husband’s cheek.
Matt too, looks away to smirk up at his wife. “We beat them this time, hm?”
Alex giggles and presses a kiss to his lips. “I think River might consider her position the winning one, darling,” she says, and together they look back over as River, straddled on the Doctor’s lap in the chair by the bed, winks at them, before she leans in and murmurs to her husband in words they only just catch.
“Your turn sweetie.”
As if under her spell, the Doctor’s hips jerk up into River’s harder, his mouth opening and knuckles turning white with their grip on River’s arse as he lets out a shout of pleasure that sounds like River’s name.
Alex feels Matt’s own hands tighten on her thighs and sucks in a sharp breath (although she is still short of it) eyes riveted to the scene in front of them as the Doctor slips a hand round between their bodies as he rides out the last of his orgasm, and River suddenly throws her head back and yells.
One of Matt’s hands move to tangle in Alex’s damp curls and he brings her head down to his own so he can murmur in her ear; “see how bloody sexy you look when you fall apart?”
A whimper slips from Alex’s lips as she watches River come hard on top of the Doctor and she squirms, feeling herself grow slick anew. “Almost as sexy as you when you’re all shagged and sweaty and panting darling,” she purrs, nodding to the Doctor who has slumped back with River collapsing into him as they both tremble and gasp for breath.
Matt grins up at her and leans up to kiss her lips, and when they finally pull apart to glance back over at River and the Doctor, they find them to be in a similar embrace, kissing tenderly and slowly and looking like each is the only thing in the world to the other. Alex smiles and rests her head contentedly in the crook of Matt’s neck; sex isn’t the only thing perfectly reflected in River and the Doctor; their love is there too.
