First a look in on the twins.

Below deck Julia was packing the the last bit of the food away in the hold. Her brother Julio smiled as he saw her bent over getting the next item. His cock stirred in his pant. It had been a couple days since he fucked Julia and he couldn't contain his desire much longer.

Julia caught some movement out of the corner of her eye, and smiled inwardly as she saw Julio creeping up behind her. Her tight kitty was almost instantly sopping wet at his presence.

She moaned as Julio's strong hands gripped her hips, pulling her back to grind against his hard member through his trousers. "Julio...I don't know if we have time for this, my love."

"Well then we will have to make time...I can not wait any longer, sister." Julio paused a second, "That is still so weird to say."

"I know what you mean. On both accounts. Hurry." she said. "Fuck me."

Receiving her permission her quickly undid his pants and flipped her skirt up. He found she didn't have any panties on. He smiled, ''Naughty Julia...claiming no time, but being prepared.'' he said as he shoved his cock into her waiting hole.

"Oh, so good. And...uh... you are wrong...I never wear panties. I like to tease the customers. Drive them wild." Julia said as she pushed back onto Julio's member. "So good. Is my pussy as good as Amber's Julio?"

"Better. Much better. To me." Julio leaned forward and ran his hands along her taught stomach up to her c cup breasts.

"Oh...Do...do you really think she'd turn us in?"

"I don't know, but we should be prepared...in case." Julio answered, picking up the pace in his fucking.

"But...she's so nice to us, I don't think she would. We...we make her happy I think." Julia said as he orgasm built up to a breaking point. Julio didn't respond, instead just grunted as she shoved back onto his thrusts. "I like her Julio. We can't betray her like our families betrayed us." Julio grunted again, feeling his balls tighten up considerably.

He came hard inside his sister's pussy, letting out a low growl as he did so. The feeling of his cum entering her set off Julia's orgasm. They both kept as quiet as possible, in case the customers had arrived. After their afterglow subsided Julio kissed his sister's neck, "I like her too, Julia. I don't want to leave here and hurt her...but if other's find out and something happens...we must be careful."

Julia nodded, "I...I trust her, Julio."
