Tex and Sister sat quietly on the cliffs, watching for any sign of Red movement. Tex, overheating in that damned hot metallic skin, had removed her armour and zipped down the front of her jumpsuit, laying against the ground and peering through the scope of her Battle Rifle at the men below.

The young Hawaiian had done much the same, but didn't bother with her gun, or jumpsuit, was lying nude tanning in the perpetual sun.

Tex resisted peeking at the girl's perfect body, but couldn't help stealing a look every now and again. She was jealous of the flawless woman beside her, not a scar on her, tan lines nonexistent, her large, succulent breasts still wonderfully perky... she caught her mind wandering into the gutter and pulled it back out, and set about looking over Red Base more.

"There's nothing to do..." Sister complained, rolling around on the elevated ground. On her back, she looked upside down at Tex. "We could fuck?"

"W-what?!" Tex questioned, caught off guard.

"You're not as good at sneaking looks as you think," Sister laughed. "And you seem like you'd be decent~ Unless you don't want to..." the girl teased, knowing Tex's answer before she did. She pulled Tex's jumpsuit down, past her hips, in one swift movement.

Tex looked back at her, mentally decided what to do, before she threw her crumpled jumpsuit against the rock face. "Good~" Sister purred into her ear, already kissing and licking down her neck.

Soft fingers danced over her areolae, but Tex refused to show weakness through sound, a challenge Sister took with a smirk. Her kisses trailed down straight between Tex's breasts, over her abdomen, stomach, and right down to her crotch.

Sister caressed down Tex's body before settling her hands on the strong woman's inner thighs. She pushed them apart and gently licked the juices off of Tex's sex, something the woman couldn't couldn't stop from coming. Still, she was adamant on her noise level.

After Sister licked the initial residue from Tex's entrance, she dipped her tongue in half an inch, ran it straight to the roof and brought her lips around Tex's clit, a brief nibble followed by sucking as she started working her tongue through Tex

Tex turned a bright red, but held fast to her pledge to stay silent. Frustrated, Sister worked a finger in with her tongue, then another. Tex finally gave up, and with a loud moan, put her hands to the younger woman's head. "D-don't stop~" she pleaded.

Sister had no intention of stopping, and kept at it till she felt Tex tighten around her fingers. She set her tongue solely to pleasuring Tex, and as Tex came, she greedily lapped up her juices.

Sister smirked, and kissed up Tex's body before Tex flipped them over suddenly, going down on her. Tex got down to Sister's womanhood, and swung herself so she her crotch was parallel with the surprised girl's face.

"It's been a while since I've done anything with a woman," Tex confided. "But I think I'll be able to manage~" with that, she dove down into the wetness below, and Sister squealed in delight as she learned Tex was a much better lover than she let on

Sister lifted her lips up to Tex again and started on her again. The two soon came together, and came once more, before they lay crumpled together, lost to the rest of the canyon but together for the moment.

As they neared the end of their patrol shift, they threw their armour back on and paced wordlessly back to base. They walked into Sister's room quietly, and disappeared room. There was a small click heard as the door locked behind them.
