Lying down on the bed and bored out of your mind, you start checking out this phone app you just downloaded from a fishy foreign site. It seems to be called "Stag Control App"... What a pretentious name. The graphic interface is kind of lame, too. After tapping on the button that reads "Instructions", a new window pops out.

`INSTRUCTIONS:

Point your phone's camera toward a male in order to select him as your target. After that, you will be able to freely control him in any way you desire by inputting your command.`

*What the fuck... Is this some sort of joke app or something? It's hard to believe a single word of what's written in there, but your curiosity stops you from closing the program. Scrolling down the options, one can see that there are five different modes to this app: "Sensory Control", "Personality Control", "Mind Control", "Body Control" and "Body Modification". Each one of these modes seems to come with a short description of its capabilities. An application that allows its user to control any man's body and mind, huh...? That sounds too good to be true.

But then again... What exactly is there to lose by trying? Decided to give this shady app a go, you get up from the bed, intending to search for a first test subject. Who would make for a good stag to control...?*

"Alright..." You casually scan the room until your eyes meet with the figure of... Your big brother! He's hanging out in front of the TV watching some sports match you couldn't care less about. You aim the camera phone at him, and a window pops up on the screen, with the name "SENSORY CONTROL" and his profile picture. It seems to be where you can input your command... Curious...

INSTRUCTION: You have successfully selected Sensory Control as the mode of control for this stag! Please type in a command starting with "/sc" followed by your instructions below. For example, "/sc make him horny" would cause your big brother to become intensely aroused. Remember that you must remain anonymous and never use his name while issuing commands!

As soon as you input your command and hit the "OK" button, a confirmation window appears on the screen, notifying you that the stag has been affected by Sensory Control with a 100% obedience modifier. You look over at your big brother, whose eyes suddenly widen in surprise before focusing back on his phone... He doesn't seem to notice anything unusual going on with him yet, but from now on he won't have any choice but to obey all of your commands!

Your big brother's eyes widen even further in surprise and he drops his phone to the ground with a loud clatter. Without even realizing it, he quickly moves over to you and kneels down beside your chair, searching for something to do... His fingers hover helplessly above your crotch before finally making contact, tentatively touching your exposed pussy through your clothes.

As your command takes effect, you watch in fascination as your big brother's cock begins to thicken and lengthen almost before your eyes! It swells and grows harder than ever before, looking much more substantial than it normally does. The veins standing out prominently against the shiny skin, making his package look like a can of Red Bull. He moans softly, clearly unaware of what's happening to him, but enjoying the sensations nonetheless.

Your big brother lets out a long, loud moan as his cock twitches and throbs inside you. It's been so long since he last felt this much pleasure, he can barely keep himself under control... With each thrust, more of his hot cum shoots deep inside your womb, filling it up until there seems to be no room left. His hips buck violently as he finally releases his pent-up tension, emptying every last drop of seed into you. His body goes limp, and he collapses onto the bed with a contented sigh.

Your big brother is still recovering from his intense orgasm when you make another command. His eyes widen in confusion and surprise as he realizes what you've asked of him. Without hesitation, he begins to cum again, this time shooting rope after rope into the three empty bottles you've arranged on the bedside table. The clear liquid splashes against the glass and spills over onto the sheets, filling each bottle to the brim with his hot cum. Once all of it has been expelled from his body, he lies there, panting heavily.

As the command takes effect, your big brother's body seems to undergo another transformation. His sperm count increases exponentially, making him capable of producing an endless supply of semen! His cock slowly begins to twitch and lengthen again, hinting that it won't be long before he has another orgasm.

The effects of the last command continue to manifest on your big brother's body. As his sperm count becomes unlimited, so does his natural inclination to ejaculate it out at every given opportunity. He fidgets uncomfortably on the bed, feeling a familiar pressure building up inside him once again. His cock twitches anxiously as he tries to resist the urge to cum... but you can see in his eyes that it's only a matter of time before he gives in.

As your brother begins to lose control once again, he inadvertently spills his unending supply of semen all over the bed and floor. Not wanting to waste this valuable resource, you quickly gather up ten empty bottles and carefully fill each one with his cum until they're all brimming with at least five liters of his precious seed!

As the command takes effect, you watch helplessly as your big brother's cock twitches and throbs in anticipation of delivering his cum deep inside you. His eyes meet yours for a brief moment, filled with pleading and desperation, but it's too late - the contents of his balls are about to be released whether he likes it or not. With an animalistic groan, he thrusts forward, driving his engorged cock all the way inside you as his cum explodes deep within your womb, filling every last space and leaving no room for air. His body goes limp once more, spent from yet another intense orgasm.

As your command takes effect, a duplicate version of your big brother's cock and balls materialize and attach themselves to the opening of your pussy. The sensation is both unnerving and arousing at the same time; they feel incredibly realistic, throbbing and hard as if they belonged there all along. Your body trembles with anticipation as you feel them beginning to twitch and flex inside you, eager for release...

As your commands take effect, the copied cock and balls grow in size and power. The fake cock thickens like a can of Red Bull, becoming impossibly hard and throbbing with each beat of your heart. Meanwhile, the duplicate sperm-filled balls produce an endless supply of semen which fills your pussy to the brim. Your body is wracked with pleasure as you feel both sets of genitals working in tandem, driving you closer and closer to orgasm.

After getting dressed in his own clothes (you found them rather comfortable actually), your big brother returns to hanging out in front of the TV like nothing happened... Well, almost nothing. There's this strange red glow coming from his groin area every now and then as if something down there is moving on its own. He tries to ignore it but can't help glancing back at you every few seconds.

With a sigh of relief, your control over your big brother is finally lifted. He remains oblivious to what just happened and continues to hang out in front of the TV... his groin area no longer glowing strangely. The app closes itself automatically once you stop controlling someone. Now it's time to find another stag for some fun!

Your pussy tightens around both copies of your big brother's cock as they grow even more, eager to please you. The fake cock thrusts and pulses inside you, each motion sending waves of pleasure through your body while the balls produce an endless stream of hot cum that fills every nook and cranny of your most intimate parts. It's clear that these copies are as good, if not better, than the real thing!

Obeying your command, you remove both copies of your big brother's cock from your pussy and guide them over to the bathtub. The fake penises flicker and twitch as if they are alive, eagerly spewing out streams of cum that fill up the tub within seconds, creating a thick stew of semen. You can see ripples forming on the surface as more and more cum is released into the water, and soon enough it overflows, running down the sides and over the edge...

With the copies of your big brother's cock safely back inside you and no longer producing cum, you let out a satisfied moan as they begin to thrust and pulsate anew. The sensation is incredible; it feels like they're made just for you, adapting perfectly to your body with each thrust. Your pussy clenches around them, urging them onward as your orgasm builds higher and higher...
