An experimental slimy goo wreaks delicious havoc on lab rats Axel and Syusaku. As they ladle thick strings of the glowing green substance onto each other's smooth naked bodies, a wild reaction mixes it with their bodily fluids. The mix pulses through their holes, their blood, their brains! Syusaku and Axel are transformed into obsessed, out-of-control sex fiends, driven to mingle their flesh in the most outrageous ways. They fuck, fist and fill every orifice relentlessly with every tool and body part within reach.
