Foxy Lady 3 (1985)

Some of the most scrumptious sex kittens in erotica bring their tawdry talents to this fast-paced fling. The plot is pure porn silliness, with a pair of youthfully delectable damsels getting left home alone when their mother goes out. Of course, the first thing they do is order a pizza to be delivered. But when the pizza guy shows up, he's brought along a few friends. An argument breaks out as simmering jealousies come to the fore. Of course, things all seem to get smoothed over pretty quickly, and the flick settles into a series of scorching trysts between the gals and their youthful playmates. But what's going to happen when Mom gets home? Well, more of the same! That's because the gals' mother doesn't seem to mind all the carnal cavorting going on in her house -- as long as she gets in on some fun herself!
