Link can't help himself and starts giving Zelda a blowjob.

Unable to help himself, Link slowly padded over to the bed, crawled inside, and stared at Zelda's erect cock tenting the blankets. A part of him was screaming that this was insane, that he was a man, that he was straight, but none of that seemed as important at that moment. Instead, Link slipped under the blanket and crawled to Zelda's crotch, her cock right in front of her, obscured only by a pair of undergarments. Link peeled those back without even thinking, and now that Zelda's thick blue cock was right in his face, he didn't have a choice anymore. He leaned forward and took it into his mouth, though it was thick enough that it barely fit. The taste was musky, but Link found himself not minding it, and began to take more of it into himself, before going up and down on it. His eyes started to drift around as he fellatioed the princess: at her masculine testicles, large and full of seed; at her thick and muscular physique, her torso covered in both fat and muscle; and oddly enough at a tiny, curly tail she had grown, right at the base of her butt.

Then Link realized Zelda was moaning as he gave her the blowjob, and while still mostly asleep, started muttering to herself, "Oh yes. Oh fuck yes..." This made Link's body flash with arousal, and he sped up his work, until finally he felt the cock pulse in his mouth, then shoot out load after load of semen, which he swallowed on instinct. The taste was strong, but not altogether unpleasant. When Link got out of the covers, she found Zelda looking at her, a glazed look on his face.
