The most intimate way for two people, usually two men, to ride a motorcycle at the same time. Allows for not only maximum enjoyment and thrill of riding a motorcycle, but also of whichever Twink you might be hung up on at the same time. Its really quite simple, the operator of the motorcycle rides the motorcycle like normal, but his passenger, who usually would ride behind him (allowing for a reach around and or light nipple play) rides in front of the driver, facing him. The possibilities that this opens up for further enjoyment of motorcycle riding are endless.
Jaun and I rode the motorcycle down to the beach last night, and we rode San Francisco Spider the whole way, you wouldn't believe hot it was frotting on the highway.

When you hit a bump in the road while driving and go flying through the air. Meanwhile, your passenger unknowingly slips a dildo under your ass, spearing you as you land back on your seat.
I hit a giant pothole on the highway, and before I knew it, the gay hitchhiker I picked up had given me the San Francisco Speedbump.

The most intimate of kisses; The San Francisco Kiss is when two people rub their buttholes together passionately as if simulating kissing. Not to be mistaken with the San Francisco French Kiss.
Look at those two men over there locked in a passionate San Francisco kiss; What a time to be alive.
