Andy stood up from his bed and checked himself out in the mirror. Just as expected, his recent orgasm made him even more mature than he was before - standing at his brother's old height of 6'4'' with similar chest hair and treasure trail adorning his thick pecs and abs. Andy flexed, feeling so powerful from all the testosterone his organ was pumping through him. "Maybe I can make myself even bigger than Jesse ever was" Andy thought to himself. Maybe he could push their changes further; Andy had to guess his brother was probably looking like a 13 year old now. As Andy finished that thought he Jesse's girlfriend Karen run out of his room and out of the house.
Andy saw Jesse walk out of his room. Jesse was barely 5 feet tall now and as hairless and skinny as a per-pubescent teen, his dick was flaccid at almost 2 inches now. "She broke up with me. Are you happy now asshole?" Jesse said, his voice cracking with almost every word.
"Sorry bro." Andy said in a deep baritone voice. "I guess she wanted a bigger man if you know what I mean. You are just a kid." Andy retorted.
"I can't believe this is happening! You look just like I did before you stole my dick. Now you make me lose my girlfriend and you think it's no big deal!?" Jesse fumed. Andy chuckled seeing his brother getting so mad in his little body - he looked like a kid throwing a tantrum.
"Relax bud, I know how to fix you." Andy said with an ominous tone and an evil grin. "Just come here and I think I can help you forget about all that's happened. You can live a blissful life as the kid you now are; you can relive the roaring times of high school!" Andy said, trying to hype his brother to the fact that Andy was attempting to take over Jesse's old life permanently.
"Wha-what are you saying?! Are you crazy!? Get away from me!" Jesse yelled and started to run. He heard Andy in pursuit and knew he needed to think of something quick.
