i thought of this myself, its when you are taking a dump in your bathroom and your partner decides to come in and suck your penis, thus making it a blumkin. but instead you flip her upside down and start to lick her vagina making the 69 position thus making it a 69 blumkin
dude omg she blew me while i was takin a shiz and i was all, "imma return the favor" so while she was still suckin i fliped her upside down and i ate her out at the same time yeah. she was like i love 69 and i love blumkins, i love the 69 blumkin.
