Next day (POV: Girlfriend)

The next morning, as you awoke first to the shuffling of the bed, you opened your eyes blearily while stifling a yawn that threatened to awake the dead.

You had spent the previous afternoon partying with some teenagers and even had made out with one, you think he had introduced himself as Garrett but weren't quite sure, but had struck out on finding some decent cock. It wasn't too disappointing, the fact that you weren't really looking either too hard, so it was consolation that you had returned to your room by yourself.

You had spotted Mom and Keith walking around the resort that evening. From the looks of things, you knew your mom had gotten some, Keith's smile and your mom's relative ease and comfort was telling to you. On the one hand, you supposed this was an affair after all (she HAD fucked another man while being married to your father). But on the other hand, you also knew that she was not your real, actual mother but rather your boyfriend.

Dinner had been an interesting affair as he had joined the two of you and as you three talked, you got the sense that Keith was taken in by your mom. He was saying all the right things, doing the right things, and your mom for her part was also very much showing how she had enjoyed her time with him and was even starting to fall for him.

After dinner, the two of them had gone off for a nightcap before your mom had returned to the room after 11, looking like she had thoroughly enjoyed herself yet again. You didn't say anything, only giving her a knowing smile before the two of you fell asleep.

As you rolled over in bed, you looked over at the person asleep in the bed across from you. Interesting...
