A chance find turned into a dirty secret...

I just wanted to drink some water... but a chance find in the kitchen cupboard awakened completely different desires in me. I didn't understand where that toy came from, but thoughts about it didn't give me peace. I turned on a movie... and lost control. It was at that moment that my stepbrother came home. He saw everything. I tried to hide, but he came up to me - with that very toy in his hands. His words were simple: "I won't tell anyone if you..." Do you think I refused?
