Now that we've discovered the Higgs-Boson particle, the scientific community is ready to tackle one of the last remaining mysteries in the known universe: female ejaculation. To figure out what this mysterious wonder liquid is all about, Danny D and his fellow science types have called in Rio Lee, England's premiere sexy squirting slut. They hit a slight snag in their research when Rio explains that, in order to start squirting, she needs to get fucked hard! Never one to balk in the face of adversity, Danny does what he must and whips out his fat cock to get Rio's pussy nice and wet. Once he's fucked her hard enough to make her squirt all over the place, Rio sucks that big dick and then climbs back up for more! Being on the cutting edge of science is a dirty job, but someone's got to do it.
