Takes a sit on your face

You stay laying down, still feeling the taste of sperm and precum in your mouth, and look up at Alexandra to see what she does next. She keeps jacking herself off and starts moving closer to you. A rush of excitement comes over you. You can't wait to pleasure your goddess again and you listen to her, carefully.

Alexandra speaks down to you, saying: "Now, for being such a good boy, you'll get a chance to be my seat for as long as I need to cum. Be sure to enjoy yourself while you're down there too."

A big smile stretches across your face and you reassure Alexandra that you'll give her all you've got. Your head gets locked between her toned legs and she starts lowering herself on to you. Her giant, beautiful ass makes contact with your face. The pressure on your head rises, as Alexandra shifts more of her weight on you. Finally, she takes a nice relaxing sit straight on your face. Her asshole is right next to your mouth, so you do what you're supposed to do and put that tongue of yours to work.

You press your wet tongue up against her anus. As you do, you feel Alexandra tense up a bit. You press harder and slip in your tongue in her ass. She lets out a moan and starts stroking her cock faster. Wanting to please her further, you stick out your tongue as far as you can and start exploring the inside of her rectum. Alexandra's breathing slightly picks up as you devour her asshole, wetting every part of it with your warm spit.

This goes on for some time until Alexandra decides that she's had enough. She lifts her ass an inch off your face and places her giant balls on your mouth. She sits back down, slightly further back now, and continues masturbating. This gives you a perfect view of her cock. You watch her hand slide up and down her pulsing shaft, and a dribble of precum falls on your forehead ever so often. You quickly understand what you're supposed to do and get to sucking her balls. You open your mouth as wide as you can, but that's only enough to get one of her voluptuous testicles in your mouth. With a bit of suction, it pops in your mouth and you start slithering your tongue all over it, lathering it in spit. You can actually feel the sperm slosh around in Alexandra's balls, and you can't wait until it finally comes out. However, this means that you won't get the pleasure of pleasing her anymore, but making her orgasm is an even better reward.

You let her testicle slide out of your mouth and replace it with the other one. You treat it just like the first one, applying a bit more suction and pressure to stimulate her even more.

After covering her balls with your spit and watching with great interest as Alexandra jacks off, things finally start moving forward. You clearly feel her start to tense up and her stroking speed increase. You start sucking on her balls even harder, quickly switching between them to give her as much pleasure as possible. You see her raise up her other hand to stroke her cock even faster. Then, she quickly lifts her ass and slams it back on your face, pressing her tightening asshole against your mouth. You hardly get enough room to breathe, but all you care about at the moment is making Alexandra's orgasm as intense as possible. Your tongue dives back into the depths of her anus and you can feel its walls tightening with every second.

Then, with a scream of pleasure, Alexandra digs her ass in your face, practically trying to get you as deep as possible, but almost squishing you in result. A huge and steady load of her seed shoots up to the sky, actually reaching the ceiling. You watch closely as it comes falling back down. Her first load misses you and splashes all over the floor behind you. The second one however, hits you right between the eyes, splattering your face in Alexandra's thick and hot cum. Many more cumshots follow suit, but after a while, they dip in volume, indicating that she's all pumped clean. Alexandra let's out a sigh of relief, finally finishing her orgasm and falls down on her back to recline. Coincidentally, she falls down on top of you, so that your head remains between her legs and her back rests on your torso. You raise your head, to see her softened cock still oozing out cum from its tip. It was resting on her thigh but the moving of your head makes it fall down and land in your mouth. You gladly lick off all of the cum covering it and collect any final dribbles if sperm that leaks out of the tip. When it finally seems she's run dry of sperm, you move her dick out of your mouth and swallow whatever you gathered. The feeling of her hot sperm running down your throat sends shivers down your spine.

It takes a while, but Alexandra finally recuperates after her orgasm and sits up straight, still keeping her legs on either side of your head. She stares down at you with the same devilish grin she had before. Her hand moves over to her limp dick and grabs it. She raises it up above your face and starts slapping you with it, leaving spots of cum all over your face.

While doing this she says: "Well well well. You've really been a good little pet, but now that I've cum, I really don't have any more use for you. Still, I congratulate you on being very obedient."

She stands up, finally lifting her weight off of your body. She walks off to the door she came out of, and you notice that it's open, as is yours.

When Alexandra exits the testing room, you finally get up off of the floor.

As you do, Alan speaks up through the speakers. "Wow, she really knows how to take charge. These results are quite satisfying. I'm sure she'll be able to do her duties even better after this session. As for you, well, good work too, for letting her try out her domination teachings. You can head back and prepare for your next test now!"

You head over to your room and take a quick shower, washing Alexandra's cum off of your face. After that, you lay in bed and chill.

You got the "Servicer" ending with Alexandra.
