A little sister of a teen boy was scared cuz she had a nightmare. She walked in on the boy whacking off. She siad

"What's that?"
The boy said "uh...that's a snake."
Girl"Oh can I sleep with you?"
Boy"Sure."

The girl crawls into bed and the boy joins her.
Girl"Good night."
Boy "Good night"

During the middle of the night the boy couldn't resist whacking off and a few seconds after he had spuged, he felt a huge pain in his dick.

"AHHHHHHHHHHHHH!!!!!" HE SCREAMED!

Girl"I know. The snake was spitting at me so I bit its head off."
