Chill Touch confusion

Hello all,

Even though I have read a thread about the same spell on this very forum, I am still confused about the exact working of this spell.

The spell says:

Range - touch
Targets - creature or creatures touched (up to one/level)
Duration - instantaneous

"A touch from your hand, which glows with blue energy, disrupts the life force of living creatures. Each touch channels negative energy that deals 1d6 points of damage. The touched creature also takes 1 point of Strength damage unless it makes a successful Fortitude saving throw. You can use this melee touch attack up to one time per level."

In my opinion, that means my 3rd level sorcerer(aberrant bloodline) could:
Cast the spell, then walk up to 3 orcs (each within 10ft., within the range of the Long Limbs bloodline power), then affect each of them with a seperate melee touch attack, in the same round.

OR does it mean:
That a 3rd level sorcerer could cast this spell, get one free touch attack that same round, and then use this spell two more times in two subsequent rounds?
If this were the case, then could the sorcerer cast different spells in the following rounds, or does that end the Chill Touch effect so the sorcerer loses his leftover attacks?

Since the rules aren't clear at all on this, and that the touch-spell rules state that there are some touch spells that target multiple creatures, I tend to believe that the first reasoning is more logical.

Can anyone clarify this a bit more for me?

Thanks in advance!

If a 3rd level caster cast the spell, they would get a total of 3 touch attacks with it. One immediately, and the 2 thereafter. The following 2 could be used with an AoO, for example, or as the next rounds attacks, etc. . .

With all touch spells that "hold the charge", if you cast any other spells it will cancel out the spell you have held, (in this case Chill Touch). Likewise, if you touch something else, even without intending to, it will release the spell on that target. This doesn't necessarily apply to things touching you, for example the party Cleric trying to heal, but it might in other cases like possibly with grapple or being swallowed.

I had accidentally posted this question in the Advice section, the response was the same there, Thank you for added clarification! I guess it's case-closed then. Should I somehow close this thread now? (I'm sorry, I'm terrible with internet forums.)
