Cums all over you

Alexandra's thrusts become longer, as she takes more and more of her cock out of your as before thrusting it back in. Finally, she quickly goes from being balls deep, to ripping her dick completely out of your ass. The sudden feeling of having her length missing from your ass and your innards moving back in place as your rectum tries to close around something that isn't there anymore takes you off guard, and you carefully watch Alexandra, to see what she's doing. She takes her, dripping wet with precum, cock in both of her hands and starts masturbating furiously. Her strokes are long and cover her whole length. You decide to follow her lead and grab your own cock in your hand, stroking it quickly.

A short while later, Alexandra starts moaning louder and louder, as you watch her cock above you twitch in her hands. She focuses more on her tip, rubbing it like it was a magic lamp. Then, with a yell, she pulls her dick skin as far back as she can and starts cumming. Her cock head is pointed straight at you and you look at her pulsing urethra like a deer in headlights. Suddenly, a shotgun blast of piping hot semen escapes her cock, shooting all over you. She keeps stroking faster and faster as her orgasm continues. Her legs shake violently and she has a hard time keeping her composure as stream after stream of hot cum gets shot out of her dick. The first load drenches your entire face, making you relatively blind, as the thick, gooey ooze cover your eyes. You don't see the second load coming, but you can hear Alexandra yelp as it shoots out. You feel its hot presence on your chest and stomach. The next one focuses on your legs and the next one- back to your chest and face. This goes on for a while, and you get drenched from head to toe in Alexandra's cum. She shoots another load directly in your gaping ass, and it swallows it whole. You jack off all throughout this onslaught of semen and cum as well. Your own, seemingly tiny cumshot lands all over your face, mixing together with Alexandra's. It soon gets buried under another sperm load from the giant dickgirl still raining her spunk down at you.

After some time, Alexandra stops spraying her spunk all over you and her orgasm subsides. She lays on the fallen over couch and leaves you laying on the ground. You take your hands and wipe away the thick layer of white slime all over it. You then lick your hands clean, finger by finger until your mouth is full with your own and Alexandra's cum. The mixture tastes very distinct, like the regular taste of cum had been amplified. It's bitter, salty, metallic and sweet all at the same time. When you're finally done cleaning your face, you stand up, and let the excess cum slowly drip off of you. You stumble over to the couch, which is not an easy job, seeing as your ass just got pounded not too long ago. You take a seat next to Alexandra on, what is technically the backrest. She is panting, out of breath from her orgasm, and so are you.

You look at each other, and when Alexandra is finally ready to speak, she does. "Wow, you really got splattered... I'm just so used to fapping, that this just seemed more natural. But I came LOTS, didn't I? This was the biggest cumshot I've ever released! All that amazing assfucking really got me hyped up."

You reply "Yeah, that sure was something. Your cum tastes very nice, just so you know!"

She says "Umm, thanks I guess." And laughs it off.

The speakers boom up and Alan says: "Well damn, that was one hot session. Great job, the both of you! You can go back to your respective rooms and we'll mark this test as completed!"

You both follow up with the orders and head back to your room. You think that maybe you should take a shower, to get all this excess sperm off of you, or maybe you could just enjoy it's smell a bit more. Who knows...

An hour later, you're laying in your bed and ready to do more testing!

You got the "Baby shower" ending with Alexandra.
