Motor biking 

Gay sex with two dicks in either hand all lubed and hit the throttle and take the turns

My pal from Lms liked motor biking liked the leather bar and double handies to finish

Motorbiking 

A pornographic act describing getting a blowjob from a girl with pigtails - holding the pigtails in each hand and pulling her head in so that she gargles on your penis, making a sound like a motorbike.

Dude, that chick will go down on anyone, she is so hardcore she is in to motorbiking!

Motorbiking 

While doing doggy-style, you insert you thumb into the girls arse several times, with your hand in the same position as if you were throttling a motorbike

JD took that girl home, bent her over, and ended up motorbiking her!!

Motorhiking 

N: Driving on vacation from one location to another between cities in an effort to maximize sightseeing opportunities the same day, especially between outdoor points of interest.

While we were in Oahu we went motorhiking along the coast because everything was so spread out.
