I've asked you, my stepbrother, to come into Uni to help me with a Uni experiment. 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 m*le arousal. We've tested it on loads of guys, but all of them have normal sized d*cks. We need to test it on a tiny d*ck, 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 d*ck first... 1 inch! F*ck 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 c*m 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 sn*ff and wank all over them. I spread my arse wide open and show you the h*les 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 d*ck. My friends fancy you and then I tell them about your d*ck 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 c*m all over yourself!! Or should I say your tiny d*ck coughed up a bit of c*m. 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?
