Strength potion

You're finally home from the gym, I feel like I barely see you anymore as you spend so much time down there, maybe I should start coming with you. You laugh as I am so lazy and don't think I've got the stamina for it. I moan a bit. You explain to me you've bought a 'strength potion' from one of the guys at the gym, to help speed up your progress. I take the potion from you and use it straight away, this weird sensation comes over me, I can't explain it, so I use it again and wow, I feel instantly stronger, energetic, this is awesome, maybe it does work after all. You try and get it back off me, but instead, I take more and more. Developing abs for the first time, my biceps grow, I've even grown a bit, I show off and flex my new muscles and begin humiliating you as you will never develop muscles like this, look at you, you're so weak and scrawny
