The act of a man cumming inside a woman vaginally, then he continuing to fuck her until the combination of semen and fem juice becomes a white frothing foam. After the foam is made, the man will then proceed to urinate inside of the woman, acting as the lemon filling.
This chick wanted me to cum and piss in her, so we wound up making Lemon Meringue Pie.
During sex, one cums inside of their female partner, and upon finishing proceeds to urinate inside of the vagina, hence creating a creamy lemon meringue dessert. To finish the job, it is encouraged to eat the concoction and share it with ones partner in a passionate kiss.
That lemon meringue pie that I just ate out of my girlfriend's vagina tasted that much better because I made it.
