Stay down (Spit roast)

Even with all of your might, you can't muster the strength to get back up. All you can do is lay there, and breathe heavily from the anal devastation you just experienced. You simply shake your head at Ava.

She looks back, weirded out and says: "Umm, did you not hear me? I said get the fuck up."

You say, with the wind still knocked out of you: "I can't..."

Mia speaks up as well. "What do you mean you can't get up? We're not done yet, so you better start walking."

You are just too tired... you say: "I'm sorry, I just can't."

Ava says: "You know what, no worries. We're understanding people, so I'm sure we'll think of something, right Mia?"

Mia responds. "I'm sure we will. Seeing as you won't move, I don't think we'll go anywhere too. How about we just fuck your sorry body right on the floor?"

Ava giggles to herself and says "Wow, I'm liking this aggressive Mia. I'm sure you'll do a great job pounding his little, stretched ass. I'll make myself comfortable right over here..."

You look up and see, that Ava is on her knees and already stroking her cock.

You say "C'mon, just give me like fiv-" you get cut off abruptly, by Ava putting her dick right in your open mouth.

You open your eyes wide and look up at her giant shaft.

Mia says "Thanks for shutting his mouth up, this fucktoy talks too much. Now, let's see if his ass can make me cum again."

Mia grabs her already hard dick and presses it against your ass. All the cum that was pumped into you, and the two cocks stretching out your ass before, makes penetration a breeze. Mia easily shoves all of her length down your ass with a single thrust.

"Damn," She exclaims, "This ass is much looser than before. Guess it'll have to do."

She starts pounding your ass with respectable **** and speed. Ava's cock head is still in your mouth. You move your tongue around it and get a good taste of the sperm that she pumped in your ass a while ago. There's not much of it, but enough to give you a sense that it's a bit salty and bitter. The flavor of the sperm mixes with the fresh precum dripping out of her dick. Without warning, she grabs a hold of your head and thrusts her entire length down your throat. You start gagging, but you can't do much to resist, as you're still pumped out from your last fucking session.

"Woah!" Ava says "I can see my dick in his throat! It's bulging right here..." She starts rubbing the noticeable cock bulge on your throat, which only makes you gag more.

"That's pretty cool, how fast can you make it move?" Asks Mia.

Ava replies "Let's see..." and begins throat fucking you with amazing speed. At this point, both of your holes are being **** by the sisters, and it feels amazing.

After countless minutes of fucking, moaning and ****, the girls surprise you with their actions.

Mia says "Hey sis, it'd be much easier to fuck his ass if I wasn't on my knees..."

Ava replies "Yeah, same for me. Let's take a better position..."

After saying that, Mia puts your legs around her waist and Ava puts your hands around hers. They both slowly stand up, with their cocks still lodged in your holes.

"Hold tight!" They both say, almost in unison.

They stand up completely, lifting your body off of the floor. You hold on as tight as you can, as the girls begin to fuck you in this position. Both Ava's and Mia's speed increases and they pound your holes with even more vigor.

Now, after half an hour of pounding, you feel the girl cocks filling your mouth and ass start to throb and get hotter. You know what this means... They start thrusting in and out of you as fast as they can, until finally pushing their entire lengths down your holes, with a moan of orgasm. The pressure against your prostate sends you over the edge as well, and you cum too. Mia's throbbing dick shoots giant loads of sperm in your ass, but since it's not joined by Ava's the effect isn't as grand, yet still quite sizable. Cum pours around Mia's dick and down to the ground, joining the cum already on it before. Ava also starts shooting ropes of cum straight down your throat. You swallow as much as you can, but some of it leaks out of your mouth and down your face. You already tasted some of Ava's cum, but now you get a fresh, hot, thick batch of her seed. After a minute of them cumming in your respective holes, they finally cease and drop you to the floor, making a splashing sound from all the cum on it. If you couldn't move before, now it feels like you're completely powerless. You just lay there, cum leaking from both your ass and mouth. You slowly doze off to sleep.

After some time, you finally come to and find the strength to stand back up. You see that Ava and Mia are nowhere to be found.

Then, a voice from the speaker comes up "Oh hey, you're awake! You were out for an hour, so we decided just to take Ava and Mia back to their room. It looks like all your hard work paid off because it seems they're actually getting along fine. You can expect to see that bonus when you're done here, but for now, make sure you head back to your room. There's more testing to be done!"

You slowly make your way back to your room, limping from your hurting rectum and pride, but still glad you managed to get the sisters back together. You take a quick shower and lay in bed for a while.

You got the "Used and bruised" ending with Ava and Mia.
