You try your hardest

Alexandra clenches her fists and pumps her twitching shaft up in your throat. You move down, to get her dick even deeper. You press hard against her prostate, making her instantly shoot a giant stream of jizz straight down your throat. Her cock is so far down, that you don't even have to swallow, it just shoots straight in your stomach. Her first load seems to be the longest, as you wait patiently for the hose-like stream to end. When the cumming is finally over, you feel pretty full of her spunk already, but that was just the beginning. You slide off of her dick, up to her tip, to get some air, but you end up breathing in another cumshot.

A powerful blast of semen hits the back of your mouth and you start **** on it. You cough around Alexandra's cock, making it cum even more, from the added stimulation. Soon enough, your mouth is filled to the brim with her steaming hot jizz. You start quickly swallowing the strongly flavored cream and more comes to fill its absence. You chug and chug as fast as you can, but after downing a gallon of jizz, you can't handle any more. You rip yourself from her tender cock and it keeps shooting cum all over the place. Giant white and slimy ropes of spunk land on you and Alexandra, coating you in a shiny white gloss.

You're curious to see how much sperm Alexandra has stored up, so you press on her prostate again, and, almost like pressing a button, she cums again. She starts panting more and more, as her entire body twitches, bucks and convulses out of pleasure. You drench both yourself and her in more semen until it finally seems like she's run dry. The last spurts of her dick fall around it, as it slowly starts shrinking down to its original size. You rip both of your arms from Alexandra's ass and it makes her cock twitch in response. She seems completely tired and actually looks passed out. You rise up between her legs and look at her face. It's covered in her own seed, but she's definitely out cold and asleep. Her entire body is covered with ropes of jizz, and so is yours.

Then, Alan speaks up through the speakers. "Damn, looks like you gave her quite the orgasm. She'll probably be out for a few minutes, but back on her feet in no time. We'll take some readings of her later to close off the test, but for now, feel free to go back to your room."

You walk back to your room and take a quick shower, feeling glad you made Alexandra experience that big of an orgasm.

You got the "Sloppy eater" ending with Alexandra.
