Moments became minutes, and minutes became hours, as time slowly crawled, Arad found himself being the one to start falling first. Nina's lust seemed insatiable, even more so than her hunger. While she could've eaten before and attempted to suppress the hunger, her thirst was genetic, inherited by blood. She'll bed him for herself, and for every poor tarrasque soul that spent a lifetime of abstinence.
It didn't matter what he tried; it all ended up exhausting and painful. He tried to switch up and try the back end, only for Nina's sphincter to end up clenching so hard it severed his thing. That was a bloody mess, and recovering from it took a lot. But luckily, it wasn't a big problem, albeit painfully horrifying.
What scared him the most was that no matter how much he unloaded into her, it all seemed to disappear into the depths of her body. At the start, he hoped that she'll get filled and he'll use that as an excuse to stop, but that now doesn't seem possible.
