Present your ass (Double anal)

You let the girls go at one another for a bit. Meanwhile, you try to think of a way to get them both involved in fucking you... The first thought that pops into your head, is having both of them have a go at your tight ass. You can't possibly think of any way this can go wrong! You start prepping, by opening the zipper on your jumpsuit, located right where your butt is, exposing your asshole to the elements. You put a couple of fingers in your mouth, coating them with spit and moving down to your ass to lube it up. You only manage to stick in two fingers for now, but you feel like that will do. Your cock gets hard and presses against the fabric of the jumpsuit, making a noticeable bulge appear.

The girls are still arguing, so you need a way to beckon them over here.

Not feeling too creative, you shout "HEY!" and that seems to be enough.

They stop their talking and look at you. The situation is a little tense, so you try your best to seduce them. You face away from them, bend down and spread your cheeks, revealing your little tight and wet asshole, ripe for fucking.

You turn your head towards them and say "Now are you gonna keep fighting, or are we gonna get this started?"

The girls take turns looking at each other and back to you until Ava finally speaks up "Well about time! Step aside bitch, your sister's got an ass to claim..."

She gestures towards Mia and starts slowly walking over to you, rubbing her cock as she gets closer. Ava walks up behind you, and you already feel her still, slightly soft, but already wet, cock head touch your ass. Ava positions herself behind you and gets you down to your hands and knees. She uses her hand to guide her cock in your asshole, slowly penetrating it. With one swift thrust, she sends her whole head in your ass. The feeling is sudden but enjoyable. Ava slowly goes deeper, until her over 8-inch cock is halfway down your anus. She doesn't go much deeper yet and starts thrusting in and out, massaging your prostate with each thrust.

Ava get's a couple of minutes of fun with you, before Mia speaks up as well. "OK... sorry if I misheard, but I didn't hear him invite YOU over, specifically. Now, if this is going to be fair, I'm getting some of that action too."

Ava looks over at Mia, not stopping her thrusting "Yeah? Well, you can have him after I'm done with him, now just sit there and wait until I'm done."

Mia replies "No fair! I'm tired of always getting seconds. If you can't share, I won't make you, but I'm taking him first."

Mia walks over to Ava and you, moving in front of you. She takes you by your shoulders, and with surprising strength, picks you up, making Ava's cock slide out of your ass. You wrap your arms around Mia's back and your legs around her hips, trying not to fall off of her body. Mia grabs her cock with her right hand and makes it erect with ease, her left being placed around your back to hold you steady.

Ava is obviously confused and says "What the hell?! I wasn't done with him yet!"

Mia replies by slowly lowering you on her own cock. The tip penetrates your ass, and it feels very similar to Ava's, almost identical. Then, Mia gets a good grip around your back and starts thrusting her dick up and down your ass. With each thrust, she gets deeper and deeper, until finally shoving her whole 8.5-inch rod down your asshole. You and Mia can't help, but to moan in pleasure. After that, she lifts you back up and starts thrusting her whole length in and out of your booty.

Ava gets really pissed from this and walks closer to both you and Mia. Ava is behind you at this point, so you don't see her coming, but you definitely feel her hands on your shoulders. She pushes you down all the way on to Mia's cock so that your head gets out of the way of Mia's face.

Ava says, smirking "You want to share? Fine then... I can share."

After saying that, she grabs her own cock and tries to push it in your ass, along with Mia's. Ava's cock is just as big as Mia's, so the task is a hard one. Mia doesn't seem to object to this plan, and brings her hands down on your ass cheeks, spreading them wider, to make room for her sister's dick. One dick in your ass already made it feel stretched out, but TWO?! You can't help but moan loudly at the feeling, of having another cock slowly creeping up your ass. Slowly but surely, Ava manages to get the tip of her dick in your ass but keeps moving further. Your ass is truly being stretched to its limits, as it gapes wade, to make room for two long, hard an hot dicks. Ava, gotten about halfway in, gets tired of waiting, and slams the rest of her length in with one thrust, making all three of you moan in unison. You can feel every bit of both of their meat in your anus, and it presses against your prostate so hard, that you almost cum right then and there. You even see a pretty big bulge in your stomach, from both of the cocks.

Now, with Mia holding you up off the ground and your body wrapped around her, and Ava standing behind you with both her AND her dear sister's cock down your stretched ass, the fun can begin. Ava is first to move out of your ass a little bit, before thrusting back in. As Ava thrusts in, Mia, in return, moves back. So starts a system, of both Ava's and Mia's cocks pistoning your ass with no remorse. The **** behind every single thrust, makes you moan and your spine tingle with mixed feelings of pleasure and slight pain, but you do not care, as your prostate has never been stimulated like this before. It doesn't take long before you cum multiple loads right in your own jumpsuit. The sheer power of the sex happening starts to rip the lower part of your jumpsuit, making the job of fucking you, slightly easier. All you see is the beautiful face and bright red eyes of Mia, a slight sweat gathering on her forehead from the exhausting fucking. You feel her giant breasts press against your chest, and Ava's tits press against your back.

It feels like tens of minutes have gone by, with nothing but grunting sounds, and faster and faster thrusting by both Ava and Mia, but you enjoy every second of it. Your ass feels completely stretched out and molded to the shape of the futa cocks. However, the girls are getting closer and closer to orgasm with each thrust. The friction against their own cocks and against the tight walls of your anus is enough to drive them to the edge of orgasm. Your cock as already gotten back to its erect state, and is ready to release another cumshot. The sisters start thrusting wildly, slowly falling out of the rhythm they set for themselves, as they finally orgasm. They scream loud, and launch their dicks balls deep in your ass, making you scream in pleasure and cum hard. The torrent of cum that floods your ass is no small matter. A huge, forceful combined load of jizz, gets launched straight in your ass, forcing your stomach to expand to make way for all the semen. The cocks are doing a good job of plugging your ass, so that no cum escapes from it, except for a few dribbles of course. You get pumped full of thick, hot and creamy jizz, and your belly expands more and more.

After minutes of straight up cumming, the girls are finally done. Mia pulls out first, you let go of her and she takes a seat on the floor. A steady stream of cum quickly sprays out of your ass, coating the floor beneath you in semen. Ava also pulls out, sitting on her side of the floor. You collapse on your back, staring up at the ceiling, while pints of cum flow out of your ass. Your anus feels strange, not being filled with two giant cocks anymore, but all you can do is lay there, on the floor, at the mercy of the two sisters.

After a minute of you all catching your breath, Mia speaks up. "Wow, that felt amazing, didn't it sis?"

Ava looks back and replies: "Yeah, I suppose. Just look at him. All used up and dirty. It's.. actually kind of turning me on again..."

Mia agrees. "Yeah, I know what you mean. I kinda feel like having another go at that ass of his. You down?"

Ava nods and stares down at you, saying: "You hear that buddy? We're not done yet! Now get up and move to the couch. There's more fun to be had!"
