When a MALE injects milk or a dairy product into a FEMALE'S anal cavity, the FEMALE then squirts it back out into a glass or beaker, & the FEMALE or MALE drinks it. A delectable treat.
"I met this chick named MARCI at the Scoreboard Bar. We went back to her pad & she allowed me to put some milk up her butt! MARCI squirted the milk back into a glass & she drank it!"

DIRTY MARCI Spanish translation; "MARCI SUCIO"

Get the DIRTY MARCI mug.
Only for the busty babes of the world. Get your guy on a chair, and climb aboard so your boobs are at mouth level. Sitting on top of him like this gives him perfect tongue access to those beauties of yours. Offer them to him like the bounteous gift they are. Run a nipple across his lips, then let him lick or suck as you bounce slowly up and down. And if you're packing enough boobage to do it, some guys go crazy if you join them in the sucking.
She put him in a chair and gave him a Dirty Marcie. She gave that kitten warm milk and sent him to bed.

Get the Dirty Marcie mug.
To masturbate with a double-ended dildo and a farm animal.
I can't believe I seen her doing a Dirty Marci as I passed the Johnson farm!
