Charmer

IT'S A CLOSE UP OF A BUMFLUFFED TEENAGER TALKING

BOY: Hey there. I hope you don't think I'm being too forward...it's just that I've noticed you around and I think you're very attractive. I think you have such wonderful blue eyes and a beautiful smile.

Well anyway, if it's not completely out of the question, and just tell me to get lost if you're not interested, I wondered if you fancied going for a drink sometime.

CAMERA PULLS OUT TO REVEAL MAN IS IN A LIVING ROOM ADRESSING A PLAIN WOMAN IN HER 50'S.

WOMAN: But Alan.....I'm your mother!

BOY: Oh right! Yes, of course. I did wonder why you kept making me meals all the time.

WOMAN: Now get to bed and let's pretend this never happened.

BOY: Yes I will....but first I think I might go say hello to that rather fine young blonde-haired lass I've had my eye on.

WOMAN: YOU LEAVE YOUR SISTER ALONE!

Sorry that's too little punch for the level of offence.

I liked it. It is twisted & sick. Dark & dangerous. Very wrong.

Thanks. I've tried to pitch it towards the more playful end of incest.

I like it but it feels a bit "sticky" in the middle if that makes sense.

It would probably work better if you cut the meals line and just had mum saying "But Alan I'm your mother! Now get to bed!"

Hmmm maybe there's something in this.
Although I'd have preferred a sillier leftfield payoff the Sister thing was a bit predictable.
