This VHS feature has no story -just 3 couples sharing a summer house way before the advent of airbnb.
The title's Lacy is cute brunette Lacy Rose, but her character is named Mary. Of course, the title is merely to sell (or back in the day rent) the video.
Folks cheat on each other, but no one cares. Anal sex is popular, and nearly every sex scene is staged on the same couch -cleanliness be damned!
Fans will see Celeste before she changed her appearance (via nose job and bigger boobs), but she still has that dumb habit of going nude yet keeping her high heels on during sex. Ah, porno realism.
Normally in a feature of this type, even an all-sexer, the summer theme would be accompanied by scenes frolicking on the beach or skin diving or surfing, but instead the characters simply hang out by that couch.
