Every Hallowe'en I love getting my magic spells out - and today I've got one which will help with your 'little' problem.
I don't care what your reasons are - you pay me - and I will cast the spell for you. It's a penis reduction spell. Helping you get your penis smaller and smaller still - there's no going back, the spell is cast - soon it will get so slow you'll no longer have to worry about it - you won't even need a cage to keep it hidden away.
Of course... all my spells have a twist... it's not just your penis getting smaller.
