Adult Time - Katrina Colt [1080p]

Two strangers, Katrina Colt and Nick Strokes, have volunteered to be test subjects in a scientific experiment. A group of scientists (Tee Reel, Tommy Pistol, Mike Mancini, Danny Mountain, Rion King) explain they're trying to see if the energy produced by human bodies during sex could be a sustainable energy source, and that sex with spontaneity and unexpectedness seems to be producing the best results so far. Eager to do their part for a good cause, Katrina and Nick start having sex while the scientists observe them, and the scientists notice that the energy produced by the sex increases every time a new factor is introduced. To test how much they can increase the energy level, the scientists join the sex one by one, leading to an enthusiastic gangbang... for science!
