I thought they were sisters, but when I went to pick them up, it turned out to be a mother and daughter pair. I managed to lure them into the studio, first seducing the mother, then the daughter, and we ended up having a mother-daughter orgy. The sex between the six mother-daughter pairs was extremely lewd, as they got so excited they forgot they were parent and child and got so worked up that they climaxed over and over again.
