A sexual act similar to titty fucking, but with the additional element of erotic lactation. Particularly popular in the nordic and scandinavian countries, it involves a woman who is currently nursing, or is otherwise able to lactate, stimulating a man's penis between her breasts by squeezing them together around the shaft. At the same time the man stimulates the woman's nipples to help her release milk. If done correctly you'll both need a good shower afterward because you'll be covered in a mixture of milk and semen.
"Honey your tits look amazing tonight! Do you think you'll have enough supply to make a swedish milkshake later?"
