Just a few more pictures

Billy smiled as he looked over his nearly naked sister's body standing before him, on the temple's stairs, wearing just her tiny swimsuit with a knike strapped to her lower leg.

The little transparent bikini put 99% of her lush 37DD-24-35 body on display and it didn't take much imagination to picture what she looked like completely naked.

"William will be so pleased." Sandy stated with an ear to ear smile as she looked over their discovery.

"Oh yeah." Billy said as he took another picture of his busty blonde sister. For some reason he felt his thick cock stirring under his bathing suit and hoped his sister didn't notice.

"It's huge." Sandy suddenly stated.

Billy began to blush as she said this before he realized she was referring to the size of the entrance to the temple.

"R-right..." Billy said, "Why don't you stand by the entrance so I can show some scale."

Sandy nodded as she walked up to the entrance and struck a pose. Excited about their find, she had no idea how small her bikini really was or how much it showed off as her brother continued to take several more pictures.

Billy tried to get as much of the temple in his pictures as he could but he kept finding himself centering on his sister's hot little bod for most of them.

"Make a muscle." Billy said and Sandy rasied up one of her arms, as she seductively stretched out one of her mile long legs, and flexed her bicep for him.

She looked like a sexy jungle Goddess standing by the ancient structure as she smiled towards her brother.

"Well.." she finally said as she lowered her arm, "lets go inside."

Billy nodded as the two explorers began to head inside the massive entryway.

Do they make it inside or does something else happen first?
