Emily was still feeling aroused from the car ride, but did her best to just find a spot on the beach with her family. They quickly found a good spot. Just as she was going to talk to her sister, she notice her parents immediately strip naked. Emily looked around to see if the beach was somehow a nude beach now, but everyone was still in the swimsuits. Her checks went red with embarrassment as she continue to watch her parents. Her father's cock was as large as her mother's leg, it didn't stay visible for long as Mike picked up Aiko and shoved his cock straight into her accommodating cunt.
Emily watch as Aiko's belly bulge as she took as much of the cock in her as possible. With some cock still visible, Emily watched as her father put on a male sling bikini strapping Aiko to his chest. The sling bikini did nothing to hide Mike's large balls and only hid some of his cock that Aiko couldn't take in.
Mike waved to his daughters and said "I'm going to go on a jog with your mother. We will be back in a while. Enjoy your time together girls." with that he went off, Aiko moaning as she bounced a bit on his cock as he jogged.
Emily was a bit flabbergasted but shock it off. Now she was alone with Gabriella. Emily decided to just sit on the towel they laid down and try to wait for Rick. Gabriella sat beside her and offered to apply sunscreen on her. She declined, but looking at Gabriella she felt like she wouldn't mind looking as sexy as her.
Emily already feeling devilish and now horny decided to spice things up before Rick arrives. She decided to tell her sister about the camera.
"Gabriella I have something to tell you." Gabriella looked at her interested in what she has to say. "The camera I used alters the people in the photo. I know you won't really believe me but I will show you, but first i need to tell you, you are actually my brother, but I sure as hell love you as my sexy sister now."
Emily heard Gabriella giggle at what she said but clearly decided to humor her by waiting for her to show. Emily got the camera ready to turn them into sexy Oni twins, she wanted to look like Gabriella, but remain her age. After awhile she got the settings correct, the only thing she didn't change was the awareness option since she is a bit scared to mess with it, but she figured as long as Gabriella held it at the same time as her, she wouldn't be affected.
Just like taking a selfie she turned the large camera to face them and told her sister to hold the other side. They decided to pose and FLASH.
Emily now looked exactly like Gabriella and Gabriella was now younger, the same age as Emily.
Emily looked at Gabriella face and saw as realization dawn on her. Emily feeling even more devilish took her sister into a deep kiss.
