Or do they make him watch as they shoot all the other men in the store

Candy has her hand on Carrie's hard ass.

Sexually turned on, Carrie whispers to Candy - what do say, shall we grab that big gun of ours and blow ALL the men in the store to pieces?

oooOOOH, yes, replies Candy

Carry presents the weapon to her.

Candy takes it, selects the security guard as her first target,
points her bazooka and shoots. He goes down, done in.

Your turn, says Candy and she passes the smoking giant gun to Carry,
who selects her next target, a rich looking businessman.

Both pairs of hands are those of slender spoilt teenage girls, small and soft.

BANG! the bazooka goes off
Bits of his brain matter go all over the wall behind him, and the rack of clothes too.

It is obvious that both girls are very very wet in heightened arousal

Your turn again, Candy

Ok, ... by this time the poeple in the shop are running away in terror, or at least trying to get near the exits, but they are cornered, trapped like fish in a jar
