a boston cream pie is when the male takes his penis and enters the rectal area from behind so there is a lot of "poo poo" on the penis and then he makes the female suck on his penis so he ejaculates thus having a brown (chocolate) penis with seamen spewing out which is the cream.

The sexual act of a large group of men ejaculating in a women's mouth then when everybody's finished in her she spits it out all over a chocolate fudge vanilla cake and serves it up to a dog and then legend has it the dog gets sick and throws up all of the semen all over her chest and then she attempts to shove as much throw up in her pussy as possible through a injecting device then spit it back out of her pussy again onto the dog. It's usually common to find the men wearing David Ortiz Red Sox jerseys and listening to the Dropkick Murphys while they are unloading in the women's mouth just to make it more Bostonish.
