Ruby going down on Sun

Yang turned around and gasped audibly. She saw Ruby - who was of course completely naked - on her knees next to Sun. Ruby's left hand was planted in the sand as she leant over his body, while her right hand gently gripped the base of his erection. Yang could barely see any of Sun's cock, however, as Ruby's mouth was hiding most of it. Yang, Weiss and Blake all looked on shocked, but unable to look away.

Ruby was oblivious to the fact that team mates were watching here, as she was too focused on completing her task. She vigorously bobbed up and down the length of that "task" whilst massaging the base. Ruby was enjoying herself, but didn't want Sun to know that. Having just discovered how much Sun was into her, she knew she had to make it clear that her current act didn't mean she felt the same way. She decided she had to make him cum as quickly as possible. She took her hands away and in one swift motion deepthroated him, taking his entire length into her mouth.

"Holy fuck, Ruby!" gasped Sun, briefly breaking the silence.

Ruby felt proud of herself but knew she had more to do. She started jerking the base more quickly whilst running her tongue over the head.

"Ruby, I'm gonna... FUCK!" Sun let out, as he shot his load inside Ruby's mouth.

Ruby held it in her mouth, stood up and turned to face Weiss. She looked her partner in the eye as she swallowed, before sticking out her tongue to show it was all gone.

"Who's small and innocent now, huh?" asked Ruby, smugly.

"That was... actually impressive..." said Weiss.

"Yeah, where did you learn to do THAT so well?" asked Blake.

"Aw thanks!" Ruby squealed and smiled, "I uh... may have borrowed a couple of your books, Blake..."

The three of them laughed.

Ruby turned to look at Yang, who was looking up into space, and had folded her arms in front of her enormous boobs.

"Yang?"

"Oh, hey Ruby," said Yang sheepishly, looking into her sister's eyes, "sorry if I seem a bit out of it, it's just that was a bit weird to see, you know?"

"I'm sorry, Yang," said Ruby, "I know that was strange and all, and I know you are still protective of me, but look, I'm 18 now, I do adult things! I know I'll always be your little sister, but yeah, I have a sex life."

"Don't worry, sis," said Yang, smiling, "in a weird way I'm kinda proud of you, that made my blowjobs look tame!"

This time all four of the girls laughed.

Ruby and Yang went to hug each other, but stopped a few centimetres apart, remembering the fact that they were naked.

"Uhh, let's wait until we have clothes on!" said Yang

"Agreed!"

"Speaking of which," Weiss interjected, "As much as I'm enjoying being naked with you guys, we can't stay on this beach forever!"
