For scientific purposes, T.T. Boy and Jessica James find themselves mating in a laboratory. Their impromptu pounding and dialogue like "secure that sphincter," "can leap tall buildings in a single load" and "my time of the month is adrift in time" give cause for alarm as Jessica and others find themselves teleported back in time at the point of their orgasm. Science friction?
There (or is it "then?"), Jessica masturbates while Sunset Thomas and Micki Lynn engage in a girl/girl lickfest. Scientists Jon Dough and Kirsty Waay attempt to duplicate this time travel phenomenon (what an excuse for sex!), while T.T. has a slice of Sweetie Pie. (Nice b.j., Ms. Pie!) Kirsty and Peter North do the nasty and Jon makes it a threesome with Sunset and Micki.
The light, entertaining plot has a good blend of chuckles and cum.
