Is it normal my daughter's friend rubs my lap with her foot

Not normal but a teenage girl has just become sexually aware and may have decided to totally fuck with you. A facial expression, a cold hard glare perhaps, may let this Lolita know that you don't want to play her game. But I think by not showing her your disapproval in some way you are actually feeding into this young woman's fantasy. Sounds like you're in for some major trouble ahead. I'd nip it in the bud if I were you.

What a nasty little skank, tell your wife! I honestly think you should have told your wife the first time she did this. This girl probably isn't a good influence on your daughter. Cancel the camping trip and stop letting this girl come over for dinner. Encourage your daughter to make some new friends who aren't sexually inappropriate.

Sounds like she wants the dick.If l was you l would tell the little hoe to stop.Before she or you destroys your marriage.And it is agaisnt the law to hook up with minor.

You can always lift and move her foot away.
Or you could just jizzamulate all over her toes.

Just say: What the fuck?! Oh watch out bud, thats my cock!

Yes. She is giving u signals. I know what she want. She want ur dick. She is feeling something inside her pussy. Donot miss the chance. Eat her top to bottom like a wild dog. U can not imagine the taste of a younger pussy. They taste so sexy. Lick her butthole. Take the taste. Just ome time u fuck her and do everything as much as possible. But after that avoid this. Ignore her every act.

She is dropping a hint that she wants to give your cock a foot job and is telling you that she wants to see your naked cock on the couch and put it between her 2 feet and rub her feet up and down on it until you spew a load all over her feet and toes.
When she does this at the dinner table , does she have her shoes on or just her socks or just barefoot ?
How old is she ?
Ask her or your daughter if her friend has ever seen a naked cock in person before.
Maybe she wants your's to be her first one and her first conquest.
A foot job will only lead to more , and then she will put it in her mouth and before she gets you off , she will undress and sit on your cock and balls and she wont care which one of her 2 holes your cock ends up going inside of , but she will alternate and manipulate your cock in both of her holes.
Then she will coax you in to taking a shower with her and when she bends over to pick up the soap , slide your cock in her bald cunt and in her dirty asshole and then make her suck your cock and balls caked with her shit on it until it is squeaky clean.

unzip your trousers and let her wank your cock off with her feet.

You don't want to cheat on your wife? Do you?

It's normal for a young girl to have a crush on a father figure.
Just to don't do anything stupid, it will ruin your marriage and relationship with your daughter

she wants your cock. give it too her
