You head somewhere

Your body starts to rock on her cock, an indication she has started walking towards what you hope is your agreed destination, though you have no way of checking. With every step, the impaled cock throbs and shifts, causing no end of discomfort mixed with pleasure. She’s stopped talking to you now that she’s moving, and part of you wonders if she even remembers you are down here. That is, until after some time you here her start to pant, followed by her horse cock stiffening even further before your bowels are suddenly filled with hot creamy liquid. Fuck she came in you! Your belly feels almost like it’s bulging, as her massive cock doesn’t let any past out your ass. Your humiliation and arousal only increases at the realization you’ll stay filled as long as your hooked on, a true cum dumpster for the beastly Futa.

Time continues to pass, though blacked out you have no way to keep track other than counting each time she cums. After five your bowls feel almost ready to burst between the large loads and the even larger cock. Only then did your body learn it’s own trick, how to have a prostate orgasm. Now all the massive pleasure and pain had an outlet, you cumming again and again with her. But unlike the Centaur who’s orgasms never seemed to lessen in their load quantity, you were soon shooting dry blanks, painfully needing to cum without the ability to reload in time. Eventually you think you pass out, though in this darkness the only reason you believe that is by cumming too again as another orgasm is ripped unwillingly from you.

You have no idea how long this was your existence, being filled more and more while cumming, passing out, and waking up again only to continue the cycle. All of this while bound, hooded, and ignored. But finally, after what felt like a mind breaking eternity, something changed.
