Hell yes!

After leaving Paula with a bellyful of cum and a semi-hard cock (she got you ready for Brock), you make your way to the gym leader, Brock stands before you, confidence oozing from him.

"I've trained my Geodude and Onix to be the best they can be, think you're up to the challenge?"

"Depends, you up for a bet?"

"What's the wager?"

"If I win, your ass is mine, if you win, my ass is yours..."

"I hope you're ready to have your ass destroyed then!"

You and Brock take up your positions and Brock wastes no time in calling out Geodude, you give him a smirk as you call out Bulbasaur.

Brock starts sweating as you tell Bulbasaur to use Vine Whip which easily takes down Geodude.

"OK Geodude, come back, it was a valiant effort... Onix GO!"

Onix emerges from his Pokeball and towers over the field, without Bulbasaur you would be sweating, however when you look over at Brock, he is sweating profusely. Before he can issue a command, you immediately yell to Bulbasaur to use Razor Leaf. Onix never stood a chance, being assaulted by a barrage of leaves which took him down in seconds.

"Onix... Come back..." Sighed Brock, a man resigned to his fate.

After both you and Brock recalled your respective Pokemon, Brock gave you the Pewter City Gym badge and watched as you put it in your Badge Case. You then smiled and moved towards Brock, lifting his chin before softly kissing his lips, he didn't resist as you started stripping him, as soon as you got him naked, you dropped to your knees and started sucking his (not as big as yours) 7" long cock, not holding back, trying to get him to cum quickly so that you could take your time breeding him..

Brock whimpered as he wasn't used to losing and as such this was a new experience for him. It didn't take long for Brock to start breathing heavy, his legs were feeling weak as his moans got progressively louder until he succumbed to the inevitable, you maintained eye contact as he wailed out his release, flooding your mouth with his cum, which you quickly swallowed.
