When The Cumdump Is Full

Lois slid her stiff prick in and out, in and out of the tight fuckhole. It was getting sloppy. She could still feel the churning pressure inside of her, the terrible liquid heat as it flowed through her cock, the ecstatic release as it finally burst out of the head...

But she could also hear the squish squish squish as her hips slammed into the cumdump, feel the sticky cum-froth churned up by their constant fucking. Beneath her, Diana had ceased trying to fuck her back. The blonde was trembling, knees weak, panting and gasping. Lois stared down and saw, through the film of jizz, that her cunt was angry, red and raw where it still gripped her dick.

The cumdump was almost fucked out.

Lois herself licked dry lips, suddenly weak and hungry. She didn't know how much semen she'd generated and pumped into the waiting womb before her, but she knew that had to be taking a toll on her body—she already felt like the end of a really intense workout session, and yet the strange audio beat urged her on and on...

...CumCumCumCumCumCumCumCum...

She could feel it building up inside her...a second or maybe final wind, a terrible potentiality, a burning pressure that was almost dying for release...and yet at the same time Lois could feel her cock start to soften, her hips to ache, her pisshole burning...and yet...and yet...

Determination flowed through Lois, cold and hard. Her hands gripped the cumdump's hips tighter, until pale flesh blossomed out between her fingers. With purpose, she shoved her failing erection into the blonde faster and harder, trying to will it into life, that final urge within her building and building...

Lois had been on the receiving end of something like this once. A lover who had held it in for two weeks, and they had made love for hours, until he was pushing rope, well past his limits...but there was still something left in him. And he had gripped her then, like a lion grabbing its mate by the back of its neck, and pounded away, trying to squeeze out that last little bit of sperm...

There was no audible pop as Lois felt the final volley pump through her dick, though she gave a little scream of mixed exultation and pain at the release. She could feel something flow out from within her, that bright, hot spot suddenly feeling empty, a warm gush around her cock as her load overflowed the cumdump's sodden cunt...and with that the blonde's legs gave way entirely, collapsing onto the floor.

Lois just barely managed to check herself from falling on top of her. She panted, weak, a little light-headed, her cock finally drooping into an arc as it softened.

"Cum receptacle filled."

The tinny voice came from the speakers. Lois barely glanced at the pink swirls on the screen, too tired to process what was on there. She was vaguely aware that someone or something was dragging Diana Reynolds away, her overflowing pussy leaving a white trail on the floor behind her.

"Please rest & rehydrate before further testing!" The computer quipped.
