You are at the foot of the bed and can seen the lovers' four thrashing feet. Rather tasty feet... So you grab one of Amber's and shove it into your maw. Amber yells, but with her single minded lover on top of her, she can't do anything as you grab another foot and stick it in your mouth too.
Say, he really is single minded. That was one of his feet this time, but he continues to thrust into Amber, ignoring your starting to eat him. Nor does he change priorities as his other foot is consumed. Amber does make an effort to keep her last foot free, but it's too tangled with her lad and soon, that too is started down your throat.

As you make your way up their legs, the boy continues his pluming of Amber who continues to demand he stop and try to stop you. Well, most of the time she is telling him to stop, but every now and then, she demands he not stop. Those thrusts have predictable effects, not to mention that the very act of being eaten is highly erotic, and Amber is exploding massively and frequently even as you swallow her knees.
With his hips going up and down, you have a good deal more problem with their thighs. Indeed, by the time you reach the hips, you are feeling almost seasick. But they taste too good to be allowed to escape and you continue swallowing as they continue climaxing.
Once past the hips, it is more fun and less work. Loverboy continues his efforts, but your head is not being shaken as much. So you can enjoy the flavor more now. Amber may be enjoying it physically, but she continues to demand he stop and fight their being devoured, which he ignores as he pounds her some more.

Eventually your lips close over their heads and they are on their way to your belly. Not that this changes anything. Even going down your throat, Amber is trying to persuade this guy to do something, and he continues to do her. This continues even after they are fully in your belly. You feel his continued thrusts into her, and her continued climaxes. This goes on so long that you feel rather envious of Amber. A pity he is in there instead of out here.
Amber may have been far too forward with him, but she does seem to have good taste in boyfriends.

It takes an amazingly long time for your belly to quiet down. The lad is still going at it when you would have guessed that he had been digested down to a soup. But finally your stomach stops moving and you can take a nap as you finish with this double meal.

That nap is interrupted when you wake to find Amber and her boy are standing over the bed. The lout announces "That was fun. Now it is your turn to be a swallowed lover." You start to protest, but before you can even get fully awake, one of them is on top of you doing improper things while the other is grabbing your feet.
