I work stocking the shelves in a shop down the road from where I live. The pathetic pay is not enough to afford a place to live. I stay in the house of a wealthy chemist named Melissa.
We worked out a deal where I would be a guinea pig for her alchemical experiments in exchange for a room to sleep in. The experiments started off mundane, but over the past couple of months have begun to get increasingly wild.
In the most recent experiment, she had me drink a potion before I left for work. It took an hour before I felt the full effects of the mystery potion. I was in the middle of stocking shelves before I noticed I had a raging erection that would not go away.
I stood in front of the shelves, using all my focus to kill my boner. A tapping on my shoulder distracted me from this. I slowly turned around to see a busty ginger girl in a low cut shirt.
"C-can I h-help you?" I struggled to make my words come out.
"I was wondering if you could show me where..." Her words trailed off as I follow her eyes down to my groin. A prominent, throbbing bulge is pushing against the front of my pants. The mark of pre-cum is slowly spreading from its source. My body is shaking at the attempts to resist blowing a load in my pants.
She says something that comes across to me as a distant mumble. My mind is too far away. I make the mistake of looking at her chest. Her deep cleavage instantly pushes me over the edge. My legs give out as wave after wave of semen is forced through and into my pants. I can feel tears in my eyes begin to make their way down my face.
