"Drok get on back." Grok said once he was in front of Drok
"Me no want Drok!" Drok said with as much dominance as he could
Grok didn't take this too well. He then started to growl softly while flexing his muscles. The growl quickly got louder until eventually Grok let out a roar that reverberated in the cave. Drok fell flat on his ass out of both surprise and fear. Grok then pounced on Drok who let out a quick moan as their cocks touched
"Grok, man! Drok, boy! Drok listen Grok!!" Grok shouted angrily
Fearing what Grok would do, Drok nodded.
"Drok listen Grok." Drok repeated submitting to the large caveman
Upon hearing this, Grok then covered Drok with whole body making sure their cocks remain touching. Drok was looking right at the middle of Grok's chest. Between the fact that he was smelling Grok's BO this close and his new stronger caveman nose, he could feel his cock become harder and his balls get tighter faster than before. He found the smell intoxicating. Drok out of nowhere licked Grok's chest. This caught Grok a little of guard, but it caused his own hard cock to twitch.
"Why Drok do?" Grok asked
"Drok no know. Drok sorry."
"No be. Do again."
Drok did it again and this time Grok let out a pleasurable moan this time.
"Keep do." Grok said
Drok was happy to do it. Something about licking the musky chest, it wasn't like anything else Drok had ever done before. Drok hadn't noticed, but his cock was hard again. However he did notice after Grok start to rub the two caveman cocks against each other. It barely took a minute for them both to cum again, it all landing on Drok's chest. Grok then got up a little and started to rub the mixed cum all over Drok's body, paying particular attention to Drok's chest. Once Grok finished, Drok began to feel warm throughout his body. He looked down at his body and saw thick coarse hair slowly growing out of it. As it grew, Drok wanted to feel it. He quickly found out that his nipples were now sensitive. He also found his skin was tanned and rougher in a few places too.
"Drok like?" Grok asked
"Drok want be caveman." he answered as all the new hair finished growing
"Last step, Grok favorite." Grok said smiling as his cock leaked pre again
