With raucous pleasure

By the time the centaurs are ready to continue on with their journey you are a drooling mess. Though you are only strapped to this centaur's cock and not being actively fucked by him, every time his cock shifts inside you he hits another weak spot. The constant changing in position keeps the feeling of fullness constantly novel, never quite letting you get used to the huge girth stuffing your fuck tunnel.

As the centaurs group up and head out, the centaur that Siora is riding falls into step next to you. You turn your head to see how she's doing. Her harness is slightly different from yours. While you were strapped to a centaur on your back, facing up, Siora was strapped to her steed facing down. Her flexible limbs stretch behind her to hold her in place. Peeking down to where the centaur's massive horse cock stuffs her pussy over-full, you see her love juices overflowing. Not only is the centaur's shaft slick with her wetness, but the excess drips over her balls and down the length of her stiff cock.

"Siora!" you try calling over to her between quick breaths, hoping to get her attention and reassure her that both of you will definitely be able to get through this without a problem. "Siora!" you call again, but by now you get a good look at her face. Her eyes are glazed over and her jaw is hanging open. With every step that the centaur takes she lets out a lazy groan as you watch his cock shift inside her lower torso. It must be hitting the perfect spots inside her as you watch her twitch and writhe against her harness. As her pleasure peaks her whole body convulses and her cock sprays several thick ropes of cum uselessly into the dirt.

You can't keep your focus on your elf companion for any longer as the twisting of the flared cock head inside your own cunt makes it press against one of your most sensitive spots. You throw your head back and moan as the oversized rod presses in just the right spots. The rhythmic poking makes you writhe and jerk as much as your harness allows you to as you get closer and closer to your own climax. As your orgasm washes over you, your cunt squeezes against the monster intruder as much as it can, molding your tunnel to its shape and smothering it in love juice.

You get no time to recover from your orgasm as the centaurs continue their travels with no breaks. The thought briefly crosses your mind to ask them to pause just a moment so you can catch your breath, but you know that would be pointless to ask. They did specifically say that they were doing this to not be slowed down, after all. All you and Siora can do now is endure it and hope your body or mind don't break in that time.
