When sitting with a girl, a man asks her if she likes fireworks. He then holds out one finger and has her touch it. He spins his finger around like a firework going up in the air while making sound effects, and lands around her shoulder. Right before his hand lands on her shoulder, the firework explodes, and he punches her in the side of the face, forcing her head down into his crotch.

Bonus points are scored if pants are off, and she lands on your dick.
While I was sitting with Casey, I took my pants off while under the blanket, and she had no idea. I then fireworked her, and she landed right on my dick. It was the best head she ever gave me!
