Still groggy from your nap, you can do nothing effective as the lad climbs on top of you. As he gets into position, you do manage to protest verbally at least "Wait! I don't even know your name!"
Not that this is all that effective. You gasp as he thrusts deep into you. But at least before he pulls back to thrust again, he mutters "Perry". Not what you consider an adequate introduction, but at least it's not Paul. The idea that Amber might have been screwing her dad weirds you out. It's bad enough that her lover is pounding you.
At least he is a good lover. With each thrust, you feel yourself getting more and more excited. It is not long before your demands he stop stop. Indeed, you suddenly feel him explode, and feel disappointment, which becomes relief when he resumes his attack on you. A moment later both of you explode in a sweet simultaneous miracle.

This seems to be a signal for Amber to start eating. Even as you happily relax, you feel your foot being grabbed and shoved into a mouth. You try to protest, and manage to keep your other foot free for a moment. But with Perry holding you down, not to mention very vigorously distracting you, you really can't do much. Soon your other foot is inside Amber's mouth, and you are on your way to her belly.
As with Amber, Perry is unconcerned that he is sharing your fate. He continues to plumb your depths, in a manner quite satisfactory to both of you. He ignores your appeals to help stop Amber, not to mention demands he stop violating you. The only assistance he gives is the accidental result of his violently thrusting hips making Amber cough and release abut half of your legs.
But this is only a temporary respite. Amber resumes eating, and this time manages to get past the hips. Now the final result is not in doubt and after a last frantic effort, you give in and yield yourself to the pleasure of the moment. Which is considerable. Perry is keeping you climbing the stairs to ecstasy and throwing yourself off the top. It is no problem to just relax and enjoy this as more and more of your torso is consumed.
A moment later, your vision is cut off as Amber swallows your head, and then you are sliding down her throat. All too soon, you are deposited in her belly.
At least Perry is not bother by this. He continues to pleasure your body, and quite successfully, even as the last of you two is sealed into the stomach. Nor does he slow down as you are digested into a soup. Indeed, your becoming as soft as butter allows him to thrust into you amazingly deeply, and wonderfully. And it is even better when you are reduced to pools of liquid that rapidly mix. You do not even notice your drifting off.

You wake again in the reforming room. Perry is present and announces as he helps you to your feet "OK, my turn. Let's get back to Amber. You two can have some lez action before I have a meal."

"Wait. She's my daughter. We can't do that sort of thing."

Perry is not convinced, and starts pulling you to the door.
