I was on an Amtrak train, heading into Vancouver. I'm 18 years old, and rather pretty. I'm skinny, an I have large breasts. My eyes are green and wide, and my hair is blonde and usually in a messy bun.

A nice sexy gentlemen, 19 years old, was right next to me. I was on the inside, so it was awkward to climb over him. We were in a 4 seated area, but it was just the two of us.

He had offered me a lemonade, so I gladly accepted. We talked and talked for around 30 minutes, and I quickly finished off around 2 liters of lemonade since it was so hot.

Lets call him Derek- he suddenly stared grinning. I looked at him confused, and I realized he was staring at my vaginal area.

"I put something in your drink," he exclaimed as he grinned, pulling his armrest down. "In a moment you'll have to pee very very badly!"

I was in disbelief, but I was proved wrong as suddenly the urge to piss was strong. I gasped as I pushed my hands tightly between my legs. I stared at him madly.

"Let me go!" I believe I had exclaimed. He ignored me as he started to get out another bottle of his lemonade, gulping it down. Te train stopped, and he quickly got off. He dragged me with him, picking me up and dragging me.

He took me to his hotel, where he stripped me and himself. He sinisterly locked the bathroom door, and I noticed be grabbed his penis slightly. I was dying, I felt my bladder contracting as I squeezed my lips shut.

He smiled evilly at me. He started to wall over to me, and shoved neon the couch. He got on top of me, pinning me down. He grabbed around 4 of the lemonades, (each about 2 liters) and started to shove them inside me. Natural instinct told me to swallow.

After consuming 10 liters of that formula, I was extremely desperate. My bladder made me seem 6 months pregnant.

I hissed as suddenly my bladder seemed to tear. Piss shot out if me and in to him.
