Dr. Sara Jayne had returned to Earth after her recent expedition only to find all logs of her adventure gone. Her ship's computer had malfunctioned in the last week before returning to Earth and nothing but it's basic life support and impulse functions remained. Obviously, nobody believed her tale of the uncharted planet in which such peculiar sexual organisms thrived, so she had to start out again with a new ship.
She decided to upgrade her equipment and take along a companion. She rented out a two man science vessel complete with cargo bay and laboratory. For a pilot, she recruited her young niece, Chelsea Jayne.
Chelsea had only just turned 18, however despite her young age, she was a prodigy of a space pilot. However, she also had a reputation for being extremely sexual, ever since she first began developing. She didn't have her aunt's bust, being only a triple D herself, she did have a very big ass as well to go along with her tight abs and short stature. It was a blessing from her Cuban half, the other side of her family that wasn't her Aunt's. As a solution to her libido problem, her parents decided to send her with her aunt on the year long expedition to try and keep her from her promiscuous lifestyle.
In addition, they also forced her to wear a new space suit. It was a revolutionary new type of chastity belt. Steel plated underwear prevented her from even touching herself, while still allowing flexible movement. It hadn't been two days since she was fitted and she was already frustrated sexually. Her insides were on fire, her skin incredibly sensitive. But she didn't have a choice, technically she was still legally in their custody until the age of 21 or until she was married.
With her new ship and her less than happy companion, Sara started off on a new trek into the vast reaches of space for new and "interesting" life.
Two months later...
Sara and Chelsea were in the same quadrant that she came to all those months ago, however without the old ships logs there was a lot of guesswork to be done as to where the old planet was.
"Sara, I am picking something up on our scanners, wanna come take a look?"
Chelsea pointed to the console. Sara's big tits brushed over her shoulder as she bent down to look. This drove Chelsea crazy. She never had been with a woman before but after months of no sexual relief, anything seemed inviting to her.
"Oh my god! It's a M-1 type planet! Can we set down on it?"
"Hold on! Of course we can, is it the same one as before?"
Chelsea was asking with the hope that they could go home early and she could get this damn suit off and get some relief.
"No, it's a different one! This is incredible. Let's use the pod and leave the ship in orbit"
"Do I have to go too?"
Chelsea was hoping to get some time alone to play with her tits, the only relief she had when her aunt wasn't right next to her.
"No, I need your help to carry the equipment, come on. Let's go."
They packed the pod and headed into the atmosphere. When they landed it was warm outside, they landed in a grassy area with some trees in the distance. After walking for about an hour, they decided to take a break near a river. As they unpacked they heard giggling coming up north. They traveled up the river until they hit a waterfall. There they saw a group of women laughing and splashing each other in the water. They all were different heights and their hair and skin color were different but one thing they all had in common was their body types. All the women there had humongous breasts, bigger than Sara's and huge asses. They all had wide hips and thick legs with skinny torsos. These women were like sex fiends and would be considered porn stars back on earth.
"Get the language modulator out!" Sara whispered harshly.
The language mod was a small microphone that had a speaker on the other side and fit inside the ears of both space explorers. It's purpose was to quickly translate alien languages. There was also a piece that was placed inside the mouth to translate the explorer's voice too.
