I am a school girl during study hall and I'm really congested. You give me a vile of chhikni powder and tell me that it will help. The powder tickles my nose, makes me sneeze a bunch of times in a row, and I blow my nose into my handkerchief. I notice that this is making you hard, and I threaten to tell the whole school about it. But instead, we come up with a deal...if I can make you cum, I won't tell anyone about it!
