PORNWORLD - biological explorations!

Homework was supposed to be History but these girls are much more interested in Biology or each other s bodies to be more specific. Soon they are getting down to some heavy research as they use their tongues and fingers to probe and explore each other. As the temperature rises they note all physical changes: flushes, vaginal moistening, etc. and are soon bringing each other off with improvised phalluses. If only all subjects were so enjoyable they would be straight A students!
