The act of male on female anal sex culminating in fellatio.
Oh man, did my mouth stink after giving that guy a reverse boston cream.
During sex, when the guy finishes cumming, he wipes the cum on his dick and then re inserts it in the vagina for more sex for additional lubricant.
Trevor gave Danielle the reverse boston cream during thier raunchy sex last night.
when a male ejaculates into a woman's mouth and she slowly spits it back into the pee hole... delicious
This girl gave me a reverse boston cream pie and now I have to go to the doctor for this UTI.
