Studying Humans

Captain West has been sent to earth to discover why humans are reproducing so successfully. She takes Katt and Pina with her and they beam own to study old boy John and his constantly erect pole! They haven't seen a cock before so they pull his trousers down and study it, marvelling as it starts to grow in their hands. They push him onto the sofa and take turns to put his penis in their mouth. Discovering that it grows more when they suck it, the girls blow him like crazy and are amazed by the cum explosion that soon follows!
