I watched this movie and remember parts of this –

It is probably after 2000.

Alien Invasion .

Turns into girls.

Tries to have sex with male characters in movie (Not Species).

When kissed by aliens (Mouth to Mouth) the partner gets freezed.

Lead girl is extremely hot (Now you know the reason) and wears specs.

Thats all I remember.

Help Appreciated and will remember you while jerking off . [ Just kiddin’ 😉 ]
