Listen. Listen listen listen. Ok so. Future!Jon domming the SHIT out of past!Jon yes. Very good and excellent. But consider:
Past!Jon who has been creeping around, searching for all the answers his future self wouldn’t give him. Maybe spending a bit too much time with Elias. And he’s underneath future!Jon, taking their strap so well, when he Asks them “What are you afraid of?”
They gasp, shudder. They should be strong enough to resist, but it takes them so off-guard, feels so good (so utterly terrifying, violating), that they can’t do anything but fuck harder into past!Jon, horrified words spilling helplessly past their lips. Unable to stop even as they both cum multiple times throughout the statement.
When it’s over future!Jon looks up and realizes they’ve switched positions without them noticing. Past!Jon gazing down at them with wonder and hunger and terror, riding out his last orgasm on their strap. Between the statement and the sex they’re both far too exhausted to move, and past!Jon falls boneless into his future self’s arms, uncertain of what the future holds for their already tenuous alliance.
