Ass up high!

You decide that it's time to get down to business. Not messing around for long, you turn away from the cage and get on the couch on all fours, leaning over the backrest and proudly displaying your ass to Eris. You can hear her riling up in her cage as you tempt her by slightly shaking your butt, invitingly. Deciding you don't want your ass to be **** TOO brutally, you cover your fingers in spit and rub your ass with saliva until its decently lubed up. As you spend a good minute fingering yourself, to prepare for Eris, you can hear her get more and more aggravated at your teasing. You decide its best to let her out before she straight up kills you.

Stretching out your leg to reach Eris's door button, you click it with your toe. You hear the door instantly slam open as Eris wastes no time gunning it for your ass. You brace yourself for the worst, but Eris delivered far more than that. In a split second after the door flies open, Eris is already right behind you, and with expert precision, lines up her monstrous cock with your wet asshole. She grabs a hold of your hips and violently thrusts inside. The power behind Eris's thrust is enough to make you yell out in shock as you feel all 17 inches of her meat slip inside your rectum. The power also causes the couch to completely tip over with you still leaning on the backrest. You and Eris topple over each other. You're left spread out on the floor with the beast-girl on top of you, still having her dick buried in your ass. Eris quickly regains her composure and picks up your ass from the floor, making you go on your knees while your torso lays on the floor, trying to hold on for dear life as Eris gets to work...

With a tightening grip on your hips, Eris pulls back her shaft a good 10 inches and slams it back inside again, grunting like a wild animal. You moan out loudly from the sensation, realizing a hard ass fucking is coming your way. You grit your teeth and inhale deeply as Eris starts uncontrollably thrusting in and out of your anus, wildly smashing her hips up against yours. Each thrust sends ripples down your spine as your prostate gets smashed by Eris's girthy cock. She pulls you in with every thrust so that her length enters fully into your ass every time. Her thrusts are wild, uncoordinated, but powerful. The room echoes with sounds of slapping skin as her powerful thighs smack against your ass cheeks. While fucking the hell out of you, Eris produces the wildest sounds - grunts, moans, yells, hums, and giggles, making you almost sure that you're being fucked by a wild animal.

After a while of violently **** your ass, you get somewhat used to Eris's fucking. Even though the feeling of 17 inches of dickgirl meat is not lost on you, you start enjoying it more and more. As you start moaning from the pleasure, Eris starts picking up her pace. Your ass gets rammed with more and more speed as time goes on. The fury of Eris's thrusting has left you a drooling mess on the floor, simply being used by her. Your eyes are half shut and your face just rests on the floor while Eris pounds your rectum with no remorse. The feeling of her huge shaft entering and exiting your body non-stop is driving you crazy. Your own cock is rock hard as your prostate gets pummeled. A slow, constant moan escapes from your open mouth as your rectum gets punished by the 17 inches of futa meat.

A while passes and all you hear is Eris's moans and grunts as she pounds you stronger and faster. You feel her thrusting get more erratic as she seems to be nearing her orgasm. Eris's rough nails dig into your hips as she grabs a tighter hold of you to thrust even faster and harder. Her humping makes you moan out louder and louder as your prostate makes your dick twitch with every thrust. You can feel Eris's cock get hotter and even expand inside of you as she nears orgasm. With some wild howls and final thrusts, Eris's plunges deep inside of you and lets out a volcano of hot seed directly into your ass. The feeling of her pulsing cock being pressed hard against your prostate is enough to make you grit your teeth and release your own screaming orgasm. You blast the floor below you with a big cumshot while Eris continually spews load after load of her hot cum inside your rectum, making you feel heavier with every pulse of her rod.

After releasing a torrent of jizz inside your ass, Eris slumps down on top of you, her weight bringing you down with her. Her giant cock is still in your ass as you both lay exhausted on the floor. Soon enough, you hear Eris start snoring, so you start thinking of what to do. If you wait for you to wake up, she might have another go with you, which would be a bit too much to handle. However, if you wake her up trying to get away, she'd be quite mad. Still, you have to get on with the day, so you try your luck at getting away from Eris.

You start by turning both of you around so that you lay on top of Eris and not the other way around. Luckily for you, Eris seems knocked out, so you turn over easily. The hard part is trying to pull yourself off of her cock, still wedged deep in your ass. You can feel that it's softer than before, but its still quite deep inside you. You start slowly standing up and feeling her rod slipping out of you. After managing to stand up and remove Eris's cock from your ass, the cum load she pumped into you starts dripping out slowly. You decide just to walk to your room to clean yourself up there, as the test seems to be finished.

To confirm your doubts, Alan speaks up, saying: "How are you feeling boy? Eris was ramming you pretty long there... I guess that's what you get for teasing her as you did. Nice touch rolling her over to the couch, though you didn't really end up using it much." He says with a laugh.

He continues: "Well, as we've seen, Eris could be useful in a fight, especially because of her wild nature, although we have no real idea on how to contain it. We'll keep her around for a bit longer and see if we can't tame her. As for you, great job today, and I'll see you in the next one!"

Alan finishes and leaves you to return to your room. You head back and wash out the surprising amount of cum Eris left inside you. After that, you take a rest, letting your anus chill after its punishment and get back to work soon after.

You got the "Got what you wished for" ending with Eris.
