Slap her! (Probably the biggest risk in your life)

Throwing all caution to the wind and basically gambling on your life, instead of running away, you choose to stay your ground and attempt to assert your dominance. You raise your arm, lean over and smack Eris right in her face as hard as you can, leaving a bright red handprint on her cheek. A loud slap sound echoes throughout the room and Eris's face shows a very confused expression as if she's not sure what just happened.

The adrenaline you gathered from this, makes sure that your dick stays hard even after just cumming. You use this to your advantage and thrust into Eris's tight ass as hard as you can. This makes her moan out in what might be pleasure or pain, you can't really tell. To keep her under control, you start fucking her ass again, much harder than before. This distracts Eris for a few more seconds before she regains her focus and stares you in the face with angry eyes once again. You quickly decide to slap her again before she gets a chance to do anything. This dazes her again and makes the bright red slap mark you left on her before turn brighter. You can hardly believe you're not dead yet but are surprised to see that Eris actually looks like she's calming down.

She still looks furious, but to give her another warning, you slap her again, all while thrusting hard into her tight asshole, making her slightly twitch and shake. You can hear that her moans pick up in volume the more you keep fucking her. Once she gets out of her daze from being slapped again and looks back at you, you instinctively raise your hand again. However, before you slap her again, you stop and see that she's wincing, her eyes shut tight and her expression looking worried. Did you actually overpower her?

You lower your hand and just keep thrusting into her. After a few seconds, Eris raises one eye to look at you. You see a frown on her face and a little teardrop in her eye. Once she meets your gaze, she quickly shifts back to wincing. You are very very surprised at how this went...

Gaining confidence from seemingly dominating Eris, you speak up, saying: "Hey, Eris! If you promise not to attack me, I promise I won't slap you again. Do we have a deal?"

Shocked, you see Eris's head nod. Could she actually understand you? You try speaking to her again.

"Are you going to behave now? Are you going to do as I say? You know what happens if you don't, right?" You raise your hand again to accent your point.

Eris winces again and starts quickly nodding her head. You swear you could even hear her whimpering like a puppy a little bit. You're absolutely baffled. You thought that Eris was a pure animal, but it seems there are some traces of humanity left in her after all. Feeling excited after finding out your new found power over her, you decide to keep seeing how much commands she can follow.

You say: "Okay, Eris. I'll stop fucking you, but you have to promise to be a good girl and simply sit down. Alright?"

Eris nods her head, looking at you with a sad face and some tears in her eyes. You even hear her sniffle a little bit. You really hope this doesn't backfire and she's not just faking it, but this really seems genuine. You stop thrusting into Eris and slowly pull out your hot and throbbing cock out of her tight ass. A small amount of cum leaks out of her asshole and dribbles on the couch. You quickly get up and take a step back from her, just in case she attacks, but you're delighted to see her compose her self and take a sit on the couch. She doesn't sit like a human though, she sits on her knees on the couch cushions, but it's good enough. She places her hands on her knees and looks up at you, wiping away a tear from her cheek. You try to console her a little bit.

You walk up to her, slowly brush your hand against her red cheek, give it a kiss and say: "I'm sorry I had to punish you, but you were being bad. If you keep being a good little girl, I won't have to do that again. Do you understand?"

Eris nods her head again, leaning into your hand while letting out a few more sniffles. You spend a few seconds thinking on what you want her to do next and finally decide.

You say: "As you can see, I'm still really hard, and your ass is the perfect thing to help me with that. Now you're going to ride my dick, and if you do a good job, I won't have to slap you again. Does that sound good?"

Eris gets a little smile on her face and nods. You take a seat back on the couch and tap your thigh to let Eris know that you're ready for her. She crawls over to you and happily gets on your lap, facing you. You almost forgot about her giant member, which seems to be half erect at the moment. You take her by the hips and lift her up a little bit, putting your cock directly below her asshole. You slowly lower her down until the head of her dick once again reaches her tight hole.

Her expression turns a bit worried, but you say: "Hey, come on, don't misbehave. Do as I tell you. You wouldn't want to make me upset again now, would you?"

Eris shakes her head and composes herself a little bit before lowering herself onto your cock all on her own. Her ass slowly envelops your dick, letting you feel the warmness and tightness of her rectum again. You watch her face as she winces while putting more and more of your meat inside of herself, slowly but surely bringing herself to the base of your shaft. She lets out a little sigh of relief. After a second long break, she starts lifting herself back up and down on your shaft, very slowly at first, trying to get used to your dick again. A few minutes pass with her still slowly rising and dropping on your dick before you have to intervene.

You say: "Look, I know you're new to this, but I really need you to go faster. If I get soft again, I'll be angry, and you know what happens when I get angry, right?" You slightly raise your hand to remind Eris who's in charge.

Eris takes the hint and starts moving faster, noticeably a bit more uncomfortable than before. A few minutes pass and she seems to have gotten used to the feeling, allowing her to go a bit faster. After a few more minutes, Eris starts gaining decent speed, making your thighs slap together with every drop of her body. You see her biting her lip and moaning every now and then, giving you a good idea that she's into this. To give her some encouragement, you reach both of your hands out and grab her bouncing ass. You grab it tight and give it a loud SMACK, sending a ripple throughout her body. This makes Eris moan out loud and pick up her speed a little more.

Minutes go by and the room is filled with grunts and moans from both you and Eris as you enjoy fucking your new pet. She's gotten exceptionally better at riding you, and you show your love for that by roughly slapping her ass again and again. Her huge breasts bounce up and down, nearly hitting your face, but being just at the perfect distance to give you a beautiful view of both her and them. One thing distracting your vision is her giant cock, which is fully erect at this point and dripping drops of precum all over you the longer you fuck. It looks red hot and ready to cum any second. You have noticed her moaning more and more, so this might be a sign that she's close to orgasm.

Getting a bit worried about her cock, through your moans and grunts, you say to her: "Hey, if you're gonna cum, you better not get any of your spunk on me got it? Not a fucking drop. If you do, I'll have to punish you again, and we both don't want that now do we?"

Eris looks at you and nods her head, having a bit of a worried expression on her face.

You continue fucking for a few more minutes before Eris's face turns red and she starts moaning more and more, increasing her riding speed significantly. You're actually feeling pretty close to cumming yourself, but you wonder if Eris will try and stop herself from cumming somehow. Right then, you watch as Eris grabs her giant hot dick in her hands, leans her head down and sticks her own cock right in her mouth. She goes as deep as she can, getting more than halfway down her monster rod, gagging herself a little bit, but determined to stay down there. Seeing her intensively pump her own cock with her hands, you finally hear her groan and release a giant cumshot straight up her own mouth. You watch her throat move as she skilfully swallows her load, gulping down every last drop of her cum, leaving nothing behind. Another load explodes from her dick, filling up her cheeks with jizz. Luckily, she's determined enough to keep you clean that she quickly swallows the entirety of that load as well. She swallows about 4 more giant loads, moaning loud every time she shoots one out and only letting a little dribble of cum escape from the bottom of her mouth and slide down her chin.

Watching her sucking off her own cock AGAIN and swallowing every bit of cum to shoot out of her dick get's you to orgasm as well. You grunt and raise your hips as you fill Eris's tight ass up with your jizz for the second time today. After you're both done cumming, you are left just a panting, sweating mess. You take a few seconds to catch a breather and look at Eris as she carefully brings up her mouth to the tip of her cock, sucking out any leftover sperm she left there. Finally, she brings her mouth off of her dick with a pop and burps again from swallowing another giant load today. Her belly looks much fuller than it was before. She looks at you happily, as if expecting you to say something.

You gather your strength and say: "Good job, Eris. You've made me very happy, and you did a very good job today. Thank you."

You watch as a glad smile stretches across her face. She slowly raises herself off of your dick, letting it pop out of her ass, still hard and red after cumming twice. Unexpectedly, you watch as Eris gets off of the couch and sits down on the ground facing you between your legs. She leans her head over to your cock, sticks out her tongue and starts licking it, cleaning it off of your cum, looking at you happily as she does. You simply lay back and rest for a moment.

Just as you start falling asleep, Alan's voice comes through the speakers. He says: "Well, someone was feeling extra suicidal today, huh? I have no idea how you're even alive after the stunt you pulled, but I gotta applaud you for your bravery. I didn't think anyone would be stupid enough to attempt having sex with a wild animal futa, and slapping the shit out of her when she gets mad, but here you are. Luckily, this has shown us that Eris indeed CAN be tamed, even if it's through rougher methods, and may even be put to work. We'll see if she's willing to follow our orders as well as yours now, and if not, you might have to come and see her more often in the future. As for now, very good job Jason. I think you've earned a little pay bonus for this test. As for now, get back to your room, and get to another test when you're ready."

As Alan stops talking, Eris has pretty much entirely cleaned your cock off of cum, leaving it spotless. You pat her on the head, command her to stay and walk back to your room. You jump into bed and take a quick nap before getting back to work. This has surely been one of your more successful tests, although you do feel a little bad about having to hurt Eris to get her to obey. Maybe there could be a different way? Who really knows.

You got the "Sodomizer" ending with Eris.
