Raising Hell (1987) - American vintage porn threesome (Shanna McCullough, Shone Taylor)

One sees this kind of small story everywhere. A little magic supply shop doing hardly any business. How do they survive? That was the problem facing shop owners Siobahn Hunter and her husband Shone Taylor. When Shone leaves town to get a loan from his tight-fisted uncle, in comes Siobhan's friend Shana McCullough and convinces her to turn the store's big and vacant warehouse into an 'establishment of pleasure". What ensues is a raunchy, racy fun-filled romp within this whorehouse warehouse.
