Pumped up legs and bubble ass. It feels so good Training my strapped bubble butt for coach, showing it off to everyone. Feels so fuckin good being an OBEDIENT MUSCLE BOY PUP for @pupcoach
Yeah bro, that’s what I wanna be.
I've been working my way into being a huge roided muscle boy, but it's never fast enough. Can the changing machine help a bro out in getting huge fast?
You get your answer as the machine as it changes to something like one of those heart pressure machines at the grocery stores. You follow the prompt that appears, arm into sleeve and palm up. Once you done that, the sleeve tightens fully and then you feel it inject you with something. You moan as the injection spreads a gentle heat into you body. The screen prompts you once it finished with the injection and tells you that you should continue your treatment of the steroids.
As the treatment continues, you find yourself even more horny. You would find a jock and show him how to fuck by using his hole after each workout at the gym. You feel you muscles bulking up quicker then before. Hell you balls and dick even grew. One day you jerk into a measuring cup and was shock one the size of your load. Triple the amount you normally shoot. The next day, you mix your load into a protein shake and give it to a twink that was on one of the treadmills. You told him that he made too much and did not wanted it to waste. He drank it all at once and went back to his workout on the treadmill while you went on doing ours.
The day after the last treatment you find yourself very horny. Hornier then the normal. You go to the gym and find a guy walking into the locker room. You follow and he sees you, stripes, then walks into the sauna. Chuckling, you strip and follow enter. Once the door is close, he grabs you and takes you cock down to the base. Moaning, you grab his head and start fucking his mouth. Your cock feels five time more sensitive as you face fuck the eager gymrat. You pull out and push him onto the bench, while you pull his legs over your shoulders. Pushing your cock right into him, both of you let out a groan of pleasure.
You fucked him hard and fast for over a hour. You breed his hole and pulled out. You start to walk out when you hear the guy you just fuck let out a sensual moan. Looking over, you see him bulking right in front you eyes. You ass tingles and you look at yourself and notice that you have lost most of the bulk you had gain. Let out a moan, the growing gymrat sat up grin. He stand and look over at you, sizing you up. You do the same and find yourself wanting his cock. It was now doubled in size and vascular.You get on you knees and start worshiping that fuckstick and the balls that were now the size of oranges. You have not suck dick in a while but you manage to suck it down to the root. Then you pop it out of you mouth and then spread you ass cheeks. He waddles right up to your hole and sink his dick right into you. You are shocked at how easy it was to take the tool in you near virgin ass.

Just like you did with him, he fuck you for over hour and filled your hole with his seed. A few seconds later, you start to heat up as you look down and notice your chest starting to inflate with size. You stand and feel your body growing. Muscles expanding. Bones elongating. Balls and cock become heavy with new size. Once the growth stop, walk out of the sauna and walk over to the scale. You gained 238 pounds. You were shock.

You lick you lips and see that the guy you just fuck was the twink a few mouths ago you gave that cum laced shake. You grin as you put on the only thing that you had to fit, your posers shorts.


Another great chest day of the cycle. Pecs felt just so full and pumped by the end. Love lifting in that stringer tank too, showing off my pecs the whole time.
Help support my growth and my showing off in more slut wear. (http://a.co/7y73min)
You’re new bros are just waiting for you to change into your new speedo. With any luck, it’ll be tighter and skimpier on you than their suits by the time you finish growing.
