sextathon 

A sextathon, like a marathon, but with sex, begins usually in the late afternoon and goes into the wee hours of the morning. Just when you think it will end, it doesn't , because one person just keeps going and going. A sextathon can last hours leaving the parties feeling dehydrated and a bit sore.

I am exhausted, didn't get any sleep. I started this sextathon with my BF and he just kept going , and going. Took me a few days to recover.

Joe: I need you to love every bone in my student body including mine.

Murphy: I want you inside my Porter Cave

..........And so forth over and over again
