A nice ride

You keep pounding in her tight pussy, feeling it stretch nicely around you. As the table rocks back and forth, you push her shirt up, playing a bit with her tits as she looked at you with a dolly smile.

"Ugh ...," you groan as you keep fucking her. Her sister, still some cum dripping from her chin onto her bigger tits, standing there and watching. Somehow it is so hot to have them both side by side and finally, you get an idea. "Cock socket," you say, "get down on your knees and suck my balls."

"Yes, master," the older sister said and dropped down on her knees again. A moment later you groan again as her cute lips wrap themselves around one of your balls, while you keep fucking her sister.

For a little while this continued, and then you feel that it was time to cum again. You pull the younger one close, flooding your cum deep into her pussy. For a moment you wondered about something, pulling up her menu. As you expected, there are a few options concerning pregnancy and you quickly ensure she isn't fertile right now.

Then you pull out and the older sister cleans your cock for a moment, while the fuck doll lays on the table. With a few quick sliders in her menu, you give the younger one a slightly bigger ass. "As your sister got some boobs, you get a bit of ass," you say.

Then you pull up the main menu, select both sisters and then the NORMAL setting. A little pop-up menu appears and you select OBLIVIOUS. A quick push and both girls freeze again, before walking back to their parents and sitting down.

A few minutes later you sit in your chair, looking over to the family, where the two young women chat with their parents, neither of them seemingly notices the older ones' bigger cleavage or the younger's thicker ass.

You lean back, using your glasses to book a suite at the mountain resort they are heading. You are sure, you will have some more fun with them during your stay. And their mom looked not bad either, you thought, before looking out of the window and admiring the quickly growing mountains left and right of the tracks,
