I'm in my lab coat, gloves, long white socks, shiny red shoes and wearing my eye glasses. Let me explain the experiment to you. There's a new pill that we are trialling which helps with male arousal. We've tested it on loads of guys, but all of them have normal sized dicks. We need to test it on a tiny dick, and I thought my stepbrother would be a perfect candidate! You will comply otherwise I'll tell stepmum that you have been stealing my panties you dirty panty wanker. You comply? Good. Take this pill and I'll check on you in an hour. Let me measure your dick first... 1 inch! Fuck sake stepbro you really are small! I come back in an hour and it's only grown half an inch but you are clearly super horny. I stimulate you to see if this will lead to further growth. I show you your stepsisters perfect big tits, I open my mouth a tease you that you would love to cum in my mouth, I push my shoes in your face and in your crotch. But I know what you like more than anything, my juicy panties. Go on then, Let me take them off so you can sniff and wank all over them. I spread my arse wide open and show you the holes you will never have. This makes you grow by maybe a quarter inch. Pathetic. It's so embarrassing having a stepbrother who has such a tiny dick. My friends fancy you and then I tell them about your dick and that they just shouldn't bother, they wouldn't feel anything. I give you one more pill and come back an hour later. You've only gone and cum all over yourself!! Or should I say your tiny dick coughed up a bit of cum. I scoop it up with a teaspoon as a sample. You will be doing this for the next month you know, everyday. Or would you like me to tell stepmum and her chuck you out?
