Two pokeballs lay on the floor in Brock's rock type gym. As Brock was naked and not expecting disruptions, one pokeball burst open to reveal his Geodude. His Geodude had a lumpy, 0.3m cock that was already fully erect and ready to go. With a mighty push, Geodude rolled Brock over, exposing his tight ass before shoving his full length into it with one powerful thrust.
Brock moaned in pleasure as Geodude began to thrust in and out, slowly and steadily gaining speed and momentum. Brock came on the rocky floor but Geodude was no way near done as he slammed into Brock's ass with more force and speed.
Geodude then let out a growl of pleasure as he shot a stream of sticky, white cum into Brock's ass. Brock moaned in pleasure and the noise startled the second pokemon who emerged from its pokeball.
The second pokemon was a huge Onix with a huge dick of 8m. Brock gasped; no way could he take a dick over six times his own height! His Geodude moved away and, as Brock opened his mouth to command Onix to stop, Geodude shoved his cock down Brock's throat and began pumping into his mouth, leaving Onix free to do as he pleased with the man.
Onix shoved the first metre of his dick into Brock's ass, causing Brock to let out a muffled scream around Geodude's cock. The vibration of Brock's mouth caused Geodude to shoot his load down Brock's mouth as Onix proceeded to push the second metre, then the third right into Brock's ass.
Onix had pushed the entire dick into Brock now, stretching him to impossible lengths. Onix then sharply pulled out, right to the tip. Just as Brock felt relieved to be empty again, Onix slammed the entire 8m length in with one powerful thrust.
Onix began to pull out and thrust in, slowly and steadily. Brock's fear and pain turned to lust, Geodude cumming into his mouth again. Onix began to reach a rapid speed surprising for the slow pokemon before shooting a huge torrent of cum into Brock's ass.
However, Brock had forgotten one thing. Onix was a snake...and snakes had two dicks. Onix's second dick was now pushing into Brock's ass right next to the first. Brock screamed around Geodude's cock again, only causing Geodude to cum. Onix's two dicks were both pumping in and out of Brock now, one then the other to create an even faster momentum than ever. The pleasure was immense and Brock came multiple times, as did Geodude.
Onix then let out a mighty roar and both his cocks shot an endless stream of cum, still pumping in and out all the while. The cum never seemed to stop as the Onix kept pumping, shoving its swollen balls from both dicks into the hole of the gym leader. Just as the endless torrent finally ended, Onix came a second time and it began all over again, pumping at mad speed into Brock's ass all the while.
Finally, after what felt like hundreds more rounds of cum, the pokemon returned to their pokeballs and Brock finally got a rest.
