Victoria said the Potion made the Mayor's cock bigger, but an erection is a separated matter.
You'll have to remind about the details of that exchange I don't remember it, were the details the same? was it the same recipe, same potency, same dose.... (was the person who made it the chosen one of two gods?)
I prefer to imagine the erection as magical event linked to the users vitality, the MC being in his prime means he gets maximum effect and any failure with the mayor is a symptom of his failing health rather than the potion... the difference between someone taking Viagra because they "need" it and someone taking it for giggles.
We can assume drinking more than 1 Potion at a time:
- Only extends the time of the effect, but the enlargement is the same as drinking only 1 Potion, OR;
- With every Potion you add the enlargement get bigger, while the time of the effect remain the same as only drinking 1 Potion, OR;
- Bigger cock + longer time.
I'm not a fan of assumptions

but I like option 3, I like a little jeopardy in my porn games, imagine taking this potion growing a massive unwieldy dick then remembering you still have to do the school run.... Damn!... just had a PTSD flashback




I think that a human that experience a bigger dick enlargement than with a Gigantic Phalus Potion can face some dangers, like:
Whats life without a little danger

Based on what little "gigantism" porn I've seen the biggest danger is getting trapped by the weight of whatever you grew to big, and in the case of fucking a dragon, I imagine that means you will be struck in her for the duration of the spell (No way you are walking anywhere with a cock that big, only her slick insides are supporting it)
- The dick exploding, and death from blood lose, OR;
- The dick tissues brake and the dick end up longer, larger, but unable to erect, OR;
- The effect is accumulative, the dick suffer no damage, but the man suffer health issues due to blood deficiency in certain organs while the Potion effect is still active.
Even if more than 1 Potion only extends the effect's time, the man will end up with a Gigantic limp dick when his libido burn out, unless he drinkd an Energy Potion.
I can certainly get behind needing an energy potion, maybe failing to meet the Energy needs means it eats your health like the cloning rod.
A magical dick, as big as a man's arm, wouldn't be too heavy for the man to handle? And only a Dragon can take that dick.
Yeah... the post ended up pessimistic. But there must be a reason why the use of more than one Potion simultaneously was never encouraged.
Of course, this is a game and the magic dick can end up been as big as we want and totally safe.
Yeah man, I got a little ahead of you answering this but I got more. we can have a special quest where the MC needs to build a special wheelbarrow for when the effect last longer than desired lol... Maybe he can use it as a battering ram
