You can't stop your hand and you start to give into the sludge on your junk. You start to use it as lube as you pump your cock up and down. The load is coming too fast as you empty into the black blob.

The black goo expands rapidly seeming to eat every last drop of cum. Where it only covered your penis and hand before the slime has a firm grasp on you wrist and is creep too close to the edge of your thighs.

You can tell the slime is trying to influence where you walk now. If it gets any bigger it's going to be a serious problem.
