radioactive cum mutates you

 gives you an abnormal love for cum

 and gives your skin the viscocity

 of cum

 your eyesight starts to evolve

 so that you can see the cum floating in a mans testicles

 your hearing evolves too, so that you can hear the cum sloshing around in their balls

 your digestive system has adapted so that you can now subsist on a diet of cum

 sooner or later, your fingers will develop little urethras that can disperse cum of their own
