"498, 499, 500!"
Asta sat up and caught his breath, having completed his training routine for the
day. He leaned up against a tree and drank some of his moguro leaf juice, coughing
with repulsion from its disgusting taste. After resting for a bit, the Hage boy got up
and began to walk back to the church where he'd take a shower, propose to Sister
Lily one more time, and hopefully have a lovely pot potato dinner. As he started to
walk, however, he almost immediately tripped on a tree root and stumbled face
first into the dirt.
"Owwwww, that really hurt!"
As Asta lifted his head, he noticed a dirty-looking black book sitting directly in
front of him. He picked it up and looked at the front cover.
"Is this someone's grimoire or something? Why's it got five leaves on it though?"
Suddenly, the book began to shake in Asta's hands. He quickly threw it back down
onto the ground, but it continued to shake, a faint red glow beginning to surround
it. The book suddenly flipped open, and pages rapidly began to turn before it
stopped somewhere in the middle and a demon began to slowly emerge from
within it. Asta, panicked and unsure what to do, stood frozen like a deer in the
headlights as the demon completely materialized right in front of him. He stood at
about 4'4" and looked to be similar in age to Asta, but the two had one big
difference: Liebe was absolutely hung for someone of his size. His cock was at
least 8" soft, balls the size of oranges hanging below them.
"Well well well, looks like someone finally found me."
"H-... Who are you!?" Asta shouted.
"Name's Liebe. Wow, never seen a human so tiny before!"
"Hey, I'm not tiny! I-... I just haven't hit my growth spurt yet!"
"Yeah sure, pipsqueak. But I guess you're in luck. I really need to get this load
outta me. Being trapped inside a book for years will really leave a guy pent up!"
"Pent up? What are you talking about?"
"You'll figure it out soon enough." Liebe smirked. In a flash, he jumped on top of
Asta. Asta tried to wrestle his way free, but he was no match for the slightly bigger
and more powerful Liebe. Liebe flipped his body over and pulled down the back of
his pants, exposing his smooth, round ass.
"H- hey! What are you doing!?"
"Sorry, this might hurt a bit at first... But don't worry, it'll feel good soon..."
"What might hu- ah- Ahhh!" Asta yelped as Liebe began to press his cock inside of
Asta, slowly pressing it deeper down into Asta's body as it hardened to over a foot
in length. Asta groaned as Liebe's cock pressed against his stomach from within
him, forming a slight bulge under the skin around his navel. Liebe bottomed out as
his balls swelled full of cum. He began to slowly fuck Asta, pulling his cock out a
few inches and then pressing it right back inside him.
"Mmm... It ah~... does feel kinda good..."
"Told ya... Wait til' I start filling you up!"
"Filling me up?"
"Man, you really are clueless, kid. Don't worry about it for now, just enjoy the
feeling."
Asta did just that, moaning louder as Liebe started to speed up his thrusts. Slowly,
Asta began to feel his cock start to harden. Confused, he reached down into his
pants with one of his hands and felt it, feeling a slight bit of wetness on the tip.
"Wh-... What's this? What's happening!?"
"Looks like your body's already starting to develop, and I've barely even let out
any pre! Seems my seed won't be going to waste with you!"
"What are you ta-ahhh..." Asta's words were stifled by an involuntary moan as
Liebe's cock extended a full 14 inches into Asta's ass, forming an even larger bulge
under his skin. As Liebe continued to fuck him, Asta felt more of the unfamiliar
substance leak out of his cock and into his hand. Almost instinctively, he began to
rub it into his cock, and was surprised by the pleasure that started to radiate from it.
He continued to jerk himself off, more pre drizzling out from his tip.
Meanwhile, Liebe rubbed his balls as they began to swell. They ached with a need
for release as Liebe continued to fuck Asta, more and more pre escaping into the
boy's body. Unbeknownst to Asta, Liebe's anti-magic had been infused into his
cum when he was sealed in the grimoire, and he was now spreading it to Asta.
Liebe was surprised that Asta's genitals had already begun to develop with so little
of it inside of him, and he knew that Asta would make for a demon far bigger than
he could ever hope to become. He somehow also knew that Asta wanted it.
Something about him gave off an air of being desperate to get stronger.
"Hey kid huf ... what's your name?"
"It's Aaaa-... Asta..."
"Asta, huh? Well Asta, you're taking to my seed quite well. Ready for more?"
"Y-... yeah..." Asta didn't quite know what Liebe meant, but the pleasure in his
body had become overwhelming, and all he wanted now was more of it.
"Good, cuz' it's comin' whether you want it or not!"
Liebe started pounding Asta even harder as the volume of pre that leaked from his
cock grew exponentially. Asta moaned as he felt Liebe's seed starting to fill up his
insides. At the same time, he started to feel a strange sensation in his balls, and he
reached his other hand into his pants to feel them.
