With a shaking hand, you reach for your corrupted dick. The bulging veins are constantly pulsing, but it seems to intensify when your hand draws near. You quickly recoil and the pulsing returns to its original rate. You reach out again, and as the pulsing continues to speed up, you grab your dick. The pulsing continues but there appears to be no ill effects. You pant as you think about how expel the corrupting symbiote, eventually settling on the most reasonable plan you can think of. You grab your cock and you begin to pump it. You moan as the symbiote slides around inside, and before long, sticky ropes of regular cum burst out of your dick and splatter all over your loins.
The first release shows no difference. The pulsing can still be felt under your hand. So you tease yourself and work yourself to climax. You can feel the level of seed lower in your balls as another much more reserved load spurts out and lands on the floor. In it, you can see a few, small black flecks. When you realize your plan is working, you start moving quicker, releasing an even more reserved load onto the floor. You observe it and notice some long black streaks, and to make sure it's gone, you remove your hand from around your dick to observe the veins. And sure enough, the bulging black veins are gone. You sigh in relief and lie down, gently rubbing your cock, free of corruption. You feel a bit of precum dribble out and run over your hands, but it feels odd. It's far cooler than usual. You pull back your hand to inspect it, and your eyes widen when you realize there is a miniscule amount of black latex currently creeping across your hand.
