You take a cough drop picked up at the pharmacy by your Mom, trying to get over your cough, not aware one of the side affects is increased erection and you have to have sex twice to get it down.

*I was sitting in my room, cough was pretty bad if you ask me. I go to the kitchen. Mom has the cough drops and I take one.* Wow. *I exclaim. my stomach stopped gurgling and I feel much better already… except… my cock which has grown exceptionally hard in the first 10 seconds of taking the pill.*

Here you go sweetie! *she gives you the pill and she walks back to her room.*
