After a rather uneventful dinner (or as uneventful as a dinner with 2 muscle behemoths could get), the dorrbell rang and your brother stood up. He opened the door and a girl you've never seen before entered.
"Hey babe." Your little brother said. Wait, that was his girlfriend? How could a guy this huge even have a girlfriend?
Upon further inspection, of course his brother only got the best of the best. A more than solid 6 feet tall, a super cute face and a rather contrasting super sexy body with big breasts and a shapely ass. You guessed she had to be around 17 or 18 years old. Anything younger than that wouldn't have fit the tastes of your brother, you guessed.
"We're upstairs. Leave us alone" He gave a life-threatening look at you, making you gulp heavily. The two left and you were alone with your mother, who said you could go as well since she wanted to do the dishes today.
You headed upstairs as well, still wanting that damn flashlight back before something happens again. Upstairs, you finally made it to the bathroom and saw the flashlight. Finally! Now you can knock down your pesky little brother back down to size and...
"Didn't I tell you to leave us alone?" Ben stood behind you like a predator finding his prey.
"B-Ben! I-I didn't want to bother you, I, uhm, just wanted... hey!" you exclaimed as your brother took the flashlight into his oversized hand.
"What even is this thing? Looks like something a loser would have." He smiled wickedly.
"Baaabe, are you coming?" His girlfriend, Brooke, asked, sounding almost desperate for him.
"Sure, just give me a second..." He looked at me maliciously and snapped the flashlight in half between his fingers, much to your shock.
Your eyes almost popped out of their sockets as you realized what this meant. It was broken, destroyed, no more changes to be made. You almost wanted to cry if it wasn't for the two parts of the flashlight beginning to shine a bright pink and a bright blue each. Suddenly, both of the parts began to shoot out their respective colored beams, the pink one hitting Brooke and the blue one... Ben!
You figured something would happen to them but... no. Nothing. Maybe it was broken for good? It wasn't until then that you saw your brother grow ever so slight. a few inches in height, a couple dozen pounds of pure muscle mass and his dick got a bit more... monstrous.
Even Brooke changed, now about 6'2" and even bustier, curvier and somewhat sexier than before.
"Aw, did I break you favorite toy? Serves you right for trying to mess with me. Now get out of my sight before I do the same to you!"
You immediately ran towards your run, shutting the door behind you and locking it. Not that it would matter had your brother decided to follow you, but it was instictively rather than clever.
So what now? The flashlight is broken and your behemoth of a brother is slowly growing even bigger, stronger, taller and more hung than he already was. Great. And his girlfriend gets amped up too. You had to find a way out of this misery. But you couldn't think of how you could exactly accomplish that.
