Nyte: a tale of twincest

Jennifer and Sarah Nyte are 18-year-old twin sisters who've been sent to strict St. Madeleine's school for being too horny. They've experimented with lesbianism, but never had a man and are just dying for one. When they get all wet for the nude statues on a museum field trip, an older archaeologist drags them to the basement for a private lesson in penis-pleasing and sister-love.
