[gurps] Just to clear my mind on Teleport Spell (4th ed)

[Maxwell C. Dancer]

Having a character who has recently received the spell, I am having some 
  conflict of understanding caused by reading the teleport spell (M147) 
and the Body Sense Skill (B181)

The Teleport spell says, "Instantly moves the caster to another location 
... A wizard must roll vs. his Body Sense skill (p. B181) in order to 
act on the same turn in which he teleports. A failed roll means 
disorientation - no actions except defence are possible on that turn..."


The Body Sense Skill says "... A successful roll lets you act normally 
on your next turn..."


Now my problem is reading the spell, it seems to imply I can teleport 
AND act on the same turn, but the body sense skill implies that I can't 
do anything else on that turn, and MAY NOT be able to do anything on the 
next turn.

So, how does it work?

Turn.1
  - Teleport up to bad guys face;
  - Whack him with big stick same turn if I pass body sense, whack him 
next turn (Turn.2) if I fail

__or__

Turn.1
  - Teleport up to bad guys face, end of turn
    (he may whack me if he hasn't acted yet or is using wait action)
Turn.2
  - Whack bad guy if I pass Body Sense, otherwise sit there with stupid 
expression on my face until next turn (Turn.3) as he whacks me (possibly 
for the second time now)


Sorry for what is probably a simple question, its just the wording of 
the two put be in two minds to how it actually works :(
