Yes

With Hogarth still holding your hair, you reach out towards the guards groin and press your fingers against the leather. Beneath, you feel a bulge begin to stir. "That's it" says Hogarth, letting go of your hair, "I'll leave you two to it then". As Hogarth heads back to his cart you are able to look at the guard, though you avoid making eye contact. He's certainly stronger than you, his thick arms and legs toned by combat training are more than a match for you, no wonder he brought you down so easily. His face is somewhat obscured by his helmet, but you see blue eyes and a short brown beard.

In your hand, you feel the guards member press against the leather holding it back. "Take it out" he commands. You fumble about trying to find out how to release the codpiece, each time you brush against his cock it bucks and twitches under his pants. Finally, you find a drawstring and loosen it allowing access to the codpiece. You stall for a few seconds but a disapproving glare from the guard quickly banishes any though of getting out of this.

You reach inside and carefully pull out the full length of his cock. It feels warm and heavy in your hands, continuing to grow and expand as you handle it. You begin tugging at it gently resulting in a fully erect, 8" dick in your hands. "I can pull my own cock, boy" says the guard as your stroking ceases to satisfy him "Hogarth said suck it" he adds, grinning. You look down at the bulbous head of the guards cock for the first time, having avoided looking before now. His long thick cock curves slightly to one side and you can see a vein pulsate beneath his foreskin. Tentatively, you lean in and lick the tip with your tongue, tasting a mixture of sweat and something saltier. The guard groans appreciatively as your tongue draws along his tip.

You open your inexperienced mouth and lower it over the end of his cock, taking in the head and as much of the shaft as you can comfortably manage, holding the rest in your hand. You make a seal with your lips and begin sucking. The guard places a hand behind your neck and gently tugs on it, prompting you to bob your head, his shaft sliding back and forth inside your mouth. The salty flavour intensifies in your mouth as the guard relaxes and allows you to pleasure him.

Deciding that you'd rather have this over quickly, you try to stimulate the guard more, moving your tongue around the head of his cock as it slides through your mouth, and gently twisting your hand up and down the remainder of his shaft. Apparently, the extra effort is appreciated and you earn a long moan from the guard. His hips begin to rock back and forth, shoving his cock into your mouth faster and finally, with a last intense moan, he releases his seed in your mouth; Thick and musky, it fills your mouth. You pull back, worried you might be sick, and spit out the cum on the ground. The guard laughs "Too much for you, eh?" he teases, squeezing the last few drops out of his cock and returning it to his codpiece. "All finished over here 'garth, cheers." he yells over to your owner.

For the first time, the concept of having someone else own you takes on its full meaning. You are not in control. You're just some object that others can do with as they wish. Hogarth calls you back to the cart. "Did you enjoy that boy?" he jeers as you climb back on.
