'I'm gonna have to suck out the poison, sarge. Otherwise you'll get infested.' She said. He grinned as she put her hand on his cock and started stroking it, his foreskin moving over his dickhead. At the same time, she used her other hand to disengage her own groinplate. She stuck a finger inside her dripping pussy, furiously masturbating as she applied the 'treatment'. The gunfire and the squeals of dying zerg only made her hornier, and she stuck a second, and then a third finger inside her cunt while she massaged her clit with her thumb. She licked his dickhead as she started pumping his cock faster.
She came quickly, her juices squirting over her hand. Feeling her squirm, the sergeant put his hands on the back of her helmet and pushed her down onto his cock. Moaning into his cock she moved her hand to his ballsack and started kneading, making him pump her head on his cock even faster as she felt his dickhead in the back of her throat.
As she sprayed her juices everywhere a second time, she felt his ballsack clench. Quickly pulling her mouth off his cock, she started jerking it, massaging his ballsack at the same time to make him cum. His jizz shot out in thick ropes, and Cate was pleased to see that although the first few volleys were a sickly yellow, most of them were a creamy white. She let the infested cum fall in the dust, and quickly put her mouth on his cock and sucked his dick, swallowing most of the healthy jizz. He shot his load down her throat, and she drank it hungrily. Seeing the evac shuttles coming down as the Hyperion launched missile barrages at the swarm, She reactivated her groinplate as the sergeant did the same. Grinning, he turned to her. 'Thanks for saving me, private.'
'No problem sir.' She answered, his sperm running out of the corners of her mouth. 'Although I think it would be best if I gave you a more thorough checkup once we get back on board'. Caitlyn winked at him and smiled coyly. As the Hyperion flew overhead, they made for the shuttles. Caitlyn smiled. They might have only just escaped, but the sperm running down her chin told her it had been a good day.
