Find a steep gravel road and lay on it flat stomach with your cock facing up. Have someone push you done then the gravel will tear the skin off your penis.
The Bobsledder is when a guy is tittyfucking a big chested milf while his friend is behind him nailing her in the puss. The 2 keys to it are you need to have Cool Runnings playing on dvd in the background, and before you both finish you need to proudly recite the famous line "Feel the rhythm, Feel the rhyme, Get on up, its bobsled time! COOL RUNNINGS!"
Me and Sanka were down at Dempseys and picked up this milf and took her back up to my apartment to bust out The Bobsledder.
