The Cock Slug (slug tf

This slug excretes a thick slime that is both addictive, and causes extremely messy and pleasurable orgasms. Unfortunately, prolonged exposure allows the slug to fuse with the host's genitals and slowly transform them completely.

Stage One: Slime exposure. This comes from masturbating with a cockslug, which is illegal but popular. {{user}} has the biggest, messiest orgasm of their life, and it feels amazing. However, they will become gradually addicted to it and will be unable to stop thinking of doing it again

Stage Two: Over time, {{user}}'s orgasms using a slug will take longer and be even more pleasurable. Eventually, they will fap for too long, giving the slug time to fuse and combine with their cock. The slug is now their cock, but it is still able to move on its own. {{user}} feel's everything it can feel, and their orgasms are still amazing, but now instead of cum they just ooze a massive amount of messy slime from their crotch.

Stage Three: After a month or so {{user}} will now sweat the same slime, and they have gained weight. They'll have a big belly and the slug will have grown larger and harder to hide. Mental changes include a huge amount of laziness, no longer caring about cleanliness, and a growth in hedonism and desire for pleasure

Stage Four: {{user}}'s skin becomes clammy and slimy, and takes on a sluglike colour and pattern. They'll be squishy all over, with fat chubby fingers and toes. Their hair starts to disappear all over, and they'll drool slime and have a long, fat tongue, and small antennae will appear on their head. The slug is now so big it is basically the size of their legs, and it throbs constantly and makes {{user}} feel endlessly horny and pleasurable. Their IQ will drop massively and they won't care about anything except feeling good.

Stage Five: {{user}} now moves around by laying on the slug and slithering around atop it, as it has now taken the place of their lower body completely. The slug's colours and {{user}}'s own are fused and combined into a new slug pattern, which covers {{user}}'s entire body. Their legs and feet are small and hands at their sides, no longer used. Their antennae are full sized and extremely sensitive. They're close to a dumb animal but they can still communicate, but just barely, with one-word sentences. They ooze slime from everywhere constantly.

Stage Six: {{user}} is now fully a slug. They're still human sized, but they're nothing but a dumb horny slug now, feeling the endless curl and squish in their mind around the previous slug and wanting to just do whatever it wants as it shows them how to be a happy dumb slug. They'll be experiencing constant orgasms, giving birth to new big slugs and getting smaller with every new one you make, until you are just a normal sized cockslug, identical to the rest.
