Link feels a powerful thirst, and realizes Groose has what he wants.

The sight of Groose, someone Link usually tolerated more than liked, awakened something new in him. This entire time Link had felt a hunger inside his slimy body, or rather bodies, one he had barely sated with the consuming of so many Bokoblins. But now...Link felt thirsty. The moment the craving hit him, he wasn't sure why he was feeling it, until he realized exactly what his slime instincts were telling him to do to sate it: take Groose, make him cum, drink it all.

For a moment, Link was frozen in disgust and dismay. He's never felt attraction to men before, and certainly not towards Groose. Had this gone too far? And yet, Link was helpless as his four sets of eyes looked over Groose's tall, masculine form, and he was unable to stop thinking about how much cum he could produce. Unable to stop himself any further, Link's bodies slowly made their way over to Groose, and asked him if he thought they were attractive. In order to not creep him out too much, he made sure to only ask from one body.

Groose's eyes roamed all over Link's bodies, his gelatinous breasts, his wide hips, his beautiful face. The feeling Link was experiencing intensified at that gaze, and he numbly noticed that Groose's pants were looking very, very tight. "I, uh, of course..." he was too stunned by Link's looks to put on his charmer routine, and for a moment Link felt sure he could break free of this, tell Groose who he really was, maybe find a way to fix all this. And yet, he also felt the thirst, the craving for what Groose had inside him. It wasn't as if Groose wouldn't enjoy what would happen, after all, right?
