Your fuckin a girl from the back at the beach and you pull out smack it in the sand and stuff it in her ass and when she screams you fish hook the bitch.
When someone is sitting in front large screen watching a YouTube video while simultaneously surfing YouTube on a laptop, phone, or tablet. This is Double-Tubing. It's great when deep-diving into a particular subject.
I always enjoy double-tubing when I need extra stimulation, or when I'm obsessed with a particular subject.
The feeling one gets when eating high quality spicy foods. The burning flavor is sensed by the taste receptors of both the mouth, and anus.
After eating at the fancy Thai place, Jimmy had to go out for ice cream that night. The double burn was so powerful he had to sit on an ice pack the next day.
