(( My goodness! )) Rex gasped audibly in their mind. (( We’ve grown in size! How can this be? ))
They studied themselves in the dark and observed tail to chest, finding that they had... increased. They were visibly bigger.
( I don’t know! ) Brendon said excitedly, watching their dicks twitch and begin to leak pre. ( But I love it! Bigger! Bigger! )
Rex was suddenly keenly aware of Brendon’s suggestion affecting them both. Their body surged a little further right before their eyes, scrunching them down under the boat.
Rex was simultaneously amazed and shocked. (( Brendon, you can... you can change us, my friend! Your very thought enlarged us! ))
( Oh God... ) Brendon blinked their eyes, shocked. ( No, there was something else there, wasn’t there? I... I made us... unstable. We were locked in and now we’re not. Does that feel right? )
(( Yes, yes! Exactly! It was like you opened some sort of barricade! Try something else!! ))
The human mind concentrated and imagined them shrinking back down to normal. The body obeyed the whim and began to dwindle.
Rex was absolutely amazed. Their dicks surged and began to bob excitedly. (( You can control our size! Remarkable! Can you... continue to reduce us? ))
Shocked, Brendon concentrated again and tried to make them smaller. To their joint shock, the turned over boat around them began to grow massive as their body shrank in perfect proportion, until the once five foot tall deinonychus measured only inches long, barely a foot. And Brendon realized they could go even smaller if he desired.
(( This is incredible! )) Rex gasped. They stood up under the boat and looked over themselves. (( How did you... how did you activate this ability? ))
( Think it has something to do with sex. It’s making us unstable. Can we calm down? Lose our arousal? )
(( Certainly, certainly. )) The tiny dinosaur laid down in the cool grass beneath the boat and concentrated on unsexy and unappealing thoughts. Their throbbing boners began to dwindle back into their sheath.
( See? ) Brendon gasped. ( That’s what it is! I can’t... do anything now. )
(( Well, we certainly can’t stay a shrunken toy dinosaur, can we? ))
( No, but I want to see if I can do other things. Can we get hard again? )
(( My pleasure. )) Rex said slyly, rubbing their sheath against the grass as a storm raged and crackled outside and soon growing hard again.
Once they had reached sufficient arousal, they both felt the ping! of their body unlocking again.
(( I felt it that time! )) Rex said in surprise.
( Me too. ) Brendon concentrated on their little body and urged it to grow. They surged forward back to their original size. They winced together, the feeling was indescribably good.
Now, Brendon concentrated on their neck, their tongue, their voice. He wanted human speech back. Rex joined with him in concentration, consenting, and they gargled oddly and pulled their head back, neck aching as something happened deep inside.
“HAUGH!” Brendon cried, feeling the sharp pull of something swelling and tugging in his throat.
(( Goodness! That hurt! )) Rex chimed in.
“It hurt.” Brendon whispered, blinking and going wide eyed as he realized he had spoken the words out loud. “Rex, we can talk!”
(( Yes, I hear that!! It seems you have control over our speech, though. I can’t say anything. ))
( What if I put you in control? )
They switched places, and rather remarkably the deinonychus ‘flipped’ to Rex instead of Brendon.
“Quite a storm tonight.” The raptor said, startled at the clearly different tone and inflection in his voice. A completely different personality.
( Fucking incredible. ) Brendon commented. ( Put me back in control, I want to try something else. )
Their boners throbbed harder as Rex got an idea. “Wait a moment, my friend,” he whispered. “I’d like to try something as well. I think you’re going to really like it.”
