On your knees, so that he'll fuck your face

You know what you asked for, might as well make it easier for both of you. You strip down and get on your knees, then open the lock.

Captain America steps out, naked as the day he was born. He strikes an imposing figure, his chest puffed out, and you can barely see his face when you look up at him. He sees you on your knees and his cock starts to harden. He steps forward silently until you're mere inches away from the member already pointing forward.

"So you're the one here to service me." His voice is deep, clearly the one he uses when giving out orders to the Avengers. "I can work with that."

He grabs the back of your head and shoves your face into his crotch. Your nose is rubbing against his pubic hair and you can smell his natural odor. It's slightly musky, and you love it.

Cap begins rubbing your face around him, and you feel his balls near you mouth. You want to lick them, but decide against it. He didn't tell you to, after all.

He pulls back, still holding your head, and begins stroking his cock with the other one. "Now that you know what it'll feel like, open up."

You open you mouth and the Captain pushes in. You **** at the sudden presence on the back of your throat, but you don't have time to react as Steve grabs your head with both hands and pushes in all the way, your nose hitting his pubes once again. You keep gagging, trying to get used to the cock, and you can hear Steve humming in pleasure, enjoying the vibrations your struggle cause.

Eventually, you start getting used to the weight on your mouth. The Captain notices it too, and begins sliding out. He makes it until just the head is in and you can taste the precum on your tongue before he moves his hips forward, pushing back in.

"You're a fast learner. That's good, kid." He says, sliding back out and in. You try to mutter a "Thank you." though it comes out messy. Steve stops and pulls out fully before slapping your face. "It's 'Thank you, sir' or 'Thank you, captain', kid. Understood?"

You'd taken the opportunity when he pulled out to breathe, but you answer him with a hoarse "Yes, sir." Steve is satisfied, and begins rubbing his cock on your face, the precum marking you.

He repositions himself in front of you and you open your mouth immediately. He grabs the sides of your head and begins pushing in, this time faster. The Captain had apparently decided you were ready and began fucking your face. You couldn't do a thing, lost in the bliss of being used as a sex toy by this perfection of a man.

After some time, Steve's pace begins speeding up, and his thrusts become more erratic. He starts moaning louder and louder, and you can tell he's close to climaxing.

"You're gonna swallow my cum, you hear me? Unless I tell you otherwise, you will always accept my seed, understood?" Steve commanded. You groan in lust at the concept, and mumble a "Yes, captain."

That drives him over the edge, and Steve begins cumming down your throat, holding your head by the back, making the seed go straight down. You swallow as much as you can, but his super-soldier juice is too much, and you can feel some leaking down the sides of your mouth.

You tried counting the pumps, but after the sixth one you couldn't focus anymore. Steve, still climaxing, begins pulling out of your throat. Some more cum hits your tongue, then he pulls out fully and pumps two more loads on your face, covering you with his cum.

You and Steve are both panting as you take in what just happened. You look down and realize you also came, completely untouched, on your floor. Steve looks down at you and wordlessly rubs his thumb on the sides of your mouth, grabbing the leftover spent and feeding it to you. You swallow and take the opportunity to suck on his thumb, which pleases Steve.

You ignore your own cum on the floor, not sure what to do about it. Steve doesn't seem to care, either, as he picks you up by the arms and makes you stand up. "This was a nice welcome, son. Now show me to the bedroom, we're not done yet." You look down and see his cock, which was flaccid mere moment ago, is already hardening again.
