Dirty Pablo
After ejaculating, the man puts a line of his semen on his penis. After placing the ejaculate on his shaft, the other participant of the sexual intercourse snorts the line up in their nose, like you would normaly do it with cocaine.
"Hey i sould really like to try a DIRTY PABLO!!"
"Ok for sure, let me collect some cum"
*snort*
"WOW that´s some good stuff."
