Nathan gazed through a transparent but quite solid barrier.
He couldn't believe that his own brother was treating him like this. Well, he could believe it, he just didn't want to. Their whole lives together had been one unending game of trying to get the upper hand on the other. Now, after having watched Drew deposit the Chronivac into the top drawer of his dresser, it appeared that Drew had finally won.
Of course, Drew had to improvise. After he grabbed his mouse brother in his fist, he realized he didn't have a suitable cage at hand for keeping him as a pet. He could rectify that situation later. In the meantime, an emptied glass canister from the kitchen held his changed sibling quite effectively.
Whiskers twitching, Nathan still smelled the pasta that had been stored in the container. He had been left there while Drew withdrew for a quick shower. When he returned, Nathan noticed he was wearing only a blue towel around his waist and the rest of his muscled form was still damp. Drew walked over to the desk and tapped on the glass canister. The taps hurt tiny Drew's ears with their excruciatingly sensitive hearing.
Drew flexed his muscles as he whipped off the towel and finished drying his body. Nathan didn't want to stare, but found himself mesmerized at his brother's huge dick. The semi-hard organ was bigger than his entire mouse body.
"Of all the things, I still can't believe you turned yourself into a puny mouse," Drew chided.
Nathan squeaked very softly as his own little mouse dick hardened and peeked out of its furry white sheath. He hated being turned on by his arrogant brother, not realizing that the display of sibling arrogance and the turning of the tables had a lot to do with his current arousal.
"Quit staring at me, you little perv," Drew said. He dropped the towel but he walked to his dresser. Until he grabbed a pair of boxers from a drawer, Nathan had entertained a fleeting hope that his brother meant to remove the Chronivac and change him back.
"Don't think I didn't notice the menu box about sexual orientation, you little perv," Drew joked. "Bi-curious! Was that your plan? Turn into a little mouse and sneak into the boy's locker room at school?"
Nathan squeaked in embarrassment. He wanted to scream that had nothing to do with it.
"I could still arrange that," Drew threatened. I don't think you've thought it through, though. I don't think a little thing like you would last too long with your typical group of muscle-bound lunkheads."
A scenario of five of the biggest jocks at school surrounding him, a tiny mouse at their feet, flashed unbidden into Nathan's imagination. They all raised their right shoes in unison. Nathan nearly yelped as the dropping shoes startled him back into reality.
Drew had finished getting dressed.
"Did you zone out on me?" Drew asked.
Nathan squeaked furiously and reared on his hind limbs to throw himself against the glass.
"Calm down, bro," Drew said. "I think I'll just keep you like this for the rest of the holidays. I don't want a mouse as a brother forever."
Nathan did calm down. He slumped back to the bottom of the canister.
"Of course, with that Chronivac, I don't have to change you back into the same old boring, stick-in-the-mud Nathan." Drew's eyes seemed to grow brighter. "If you really have guy on guy feelings, maybe I should amp up those settings. Make you into a card-carrying gay guy."
He laughed as the little mouse grew agitated again, squeaking up a storm.
