A/N: I'm going to mix up clean and dirty ones so get ready XD

Edit 22/3/17- I've put a little * next to the dirty ones.

...

Clint Barton/ Hawkeye*

I was going to tell you a joke about my penis but it's too long.

...

Tony Stark/ Iron Man*

I wasn't staring at your boobs; I was staring at your heart.

...

Pietro Maximoff/ Quick Silver

Are you a beaver? 'Cause dam!

...

Thor Odinson

I bet you would look nice in some maternity armour.

...

Sam Wilson/ Falcon*

You must work at KFC, 'cause those are great breasts and legs.

...

Natasha Romanoff/ Black Widow

I think you'll find it shocking just how flexible I can be.

Bucky Barnes/ The Winter Soldier

Are you lost ma'am? Because heaven is a long way from here.

...

Scott Lang/ Ant-Man

If I said you had a beautiful body would you hold it against me?

T'Challa/ Black Panther

I'd like to get your tongue.
...

Steve Rogers/ Captain America

I love you today, but in ten years time, I'll love another girl. She'll call you mommy.

...

Loki Laufeyson

If you stood in front of a mirror and held up 11 roses, you would see 12 of the most beautiful things in the world.

...

Wanda Maximoff/ Scarlet Witch

I used to be a Gambler, but then I realized that all I needed was the Queen of my Heart.

...

Bruce Banner/ Hulk

I wish I was Adenine so I could be paired with you.

Peter Parker/ Spider-Man

When I'm older, I'll look back at all of my crowning memories, and I'll think of the day my children were born, the day I got married, and the day that I met you.
