Opening his eyes, the giant slowly looked back and forth, surveying his surroundings with a confused expression. "That's odd," he said, his voice echoing loudly even without him raising it. "I don't remember all this water... I must've been asleep longer than I thought!" He proceeded to stretch his arms and shake the water from his hair, still unaware of Daniel's presence. 'Hm... he doesn't seem hostile,' thought Daniel. 'I might as well try and get his attention; I'm probably not getting out of this mess any other way...'
"Hey! Down here!" he called, yelling and waving his arms in an attempt to alert the giant to his presence. No such luck, it seemed, as the giant boy didn't even turn in his direction; his voice was just too quiet to a being of his scale. "Crap... okay, that's not going to work. I need to approach this from a different angle... but how?" He mulled over various solutions in his head; most, he determined, would not work simply because he was too small.
"Dammit, I gotta think of something already before he either moves or his erection wears off... think; I'm on a giant's penis. How would I get his attention...?" Daniel suddenly blushed bright red as he realised the solution. However, he decided his life took precedence over embarrassment, and began furiously rubbing the skin around him, hoping to get a reaction. The giant boy suddenly stopped what he was doing, suddenly aware of a tiny but noticeable sensation in his nether regions. "What is- aah... that?" he said, panting slightly but otherwise not responding.
"Damn, it's still not working," lamented Daniel. "I'm going to have to get drastic if I wanna get out of this deathtrap." He made his way toward the huge slit at the tip of the giant's cock and gingerly pushed his arms inside. The pleasant sensation the giant felt earlier suddenly magnified in intensity, as he began to moan loudly and huge beads of sweat formed across his skin, cascading downward. The huge boy's pleasure was nearly palpable, and Daniel almost began to feel slightly aroused himself, as if the feeling were contagious.
"Haaa... wh-what is-- aah-- going on down there?" the giant croaked out, too consumed by ecstasy to speak coherently. He looked downward toward his groin and, with his otherworldly eyesight, spotted a tiny form atop his manhood, hunched over his slit and looking as if it were about to fall in. Trying to part the haze over his mind, the giant called out as quietly as he could. "H-hello? Who-- mmm... er, who are you?" Even his whisper was loud to Daniel's ears, and the sound easily caught his attention. He stopped what he was doing and turned around, looking up past the giant boy's perfectly sculpted upper body and toward his massive face.
"Oh! Uh, hi, there," he said, blushing again. "Uh, I'm Daniel, a human. I was kinda sailing along when I got stuck on top of your, er... yes, anyway, I was just trying to get your attention, hehe." The giant smiled, amused at his answer. "Well, you certainly got it, little guy! How can I help you?"
