1) During sex, pulling out from one girl and inserting your penis (hot rod) into another girl's vagina while it's still warm.
2) In the same night, after having sex, have sex with another woman so your dick is still hot form the last.
Wow... I managed to pick up two girls last night and went hot rodding from one to the other all night!
After I was done having sex with Cherryl, I was still horny so I called up my ex and went hot rodding over to her place!
