Even after all this time, Izzy still chokes the first time Ed bumps up against his gag reflex. But he’s determined, and they both love this, so he tucks his thumb into his fist and pushes himself forward, taking Ed’s cock into his throat.
He feels tears pricking at the corner of his eyes as he swallows, his throat convulsing and tight around Ed. Izzy can’t help but let out a pleased hum at the moan above him, at the hand petting through his hair, at the, “Good, Izzy. You’re so good.”
Once Izzy’s used to the intrusion he taps Ed’s thigh, signaling that he’s ready, and the hand in his hair moves to the back of his head, gripping him tight as Ed begins to thrust. He’s slow at first, making sure for himself that he’s not going to hurt Izzy, before going harder and faster, using Izzy’s mouth and throat as he sees fit.
It lets Izzy melt happily, dropping his hands to his lap and sinking down another inch onto his heels, relaxing his thoughts as well as his body. He can feel himself start to drift off, focused solely on the pleasure of being useful and good for his Captain.
It helps that Ed keeps murmuring out praise, far softer than his rough treatment would suggest. Calls him good and lovely, beautiful and devoted. Tells Izzy that he’s doing so well taking care of his Captain, letting himself be used. That he looks so hot with his lips stretched wide around him.
Ed places a hand on Izzy’s neck, not to choke (not this time), just to feel his cock pushing its way in. Izzy moans around him, and the vibrations are just enough to pull him over the edge, burying himself deep to come down Izzy’s throat. Izzy swallows gratefully.
