"Yes... Master"

Hal smiles as the words leave her mouth and says,
"Good girl",
Hal slowly walks up to you, stroking his huge, hard cock. You can't help but stare at it with lust in your eyes and surging through your body. He looks down at you, the naughty smile still covering his face and says,
"Alright John, you want to fuck Amy right?", you nod slowly, flickering your eyes between his hard cock and his girlfriend's sexy body, you focus on her round, perky tits and shapely, tight ass. "Well, if you do, you're going to have to do something for me first, I want you to suck my cock and get me to the brink of orgasm, as a reward you can taste Amy's pussy again, and maybe even her ass if your a good little pet. Once you've finished pleasing her, you'll get your next task and a better reward, every time you're a good little pet for us, the rewards you receive will get better and better."

As he speaks, you feel your cock twitching and getting harder, a few hours ago you would have never agreed to sucking Hal's cock in order to taste his girlfriend, but right now your lust and the smell of Amy's juices on your face are driving you wild enough to maybe just agree.

All the while he's talking you can't help but notice Amy playing with her wet pussy, she rubs her fingers along her clit, occasionally inserting one inside of herself, before bringing it up to her mouth and sucking her finger clean. She notices you watching her and smiles slyly before winking at you and looking down at the bed sheets where you are beginning to create a considerable tent.
