didn't see that coming (Pietro Maximoff X Reader)

He walked in with two others. They looked about your age. Early twenties. You tilted your head.

"Who are these Clint?"
You asked walking over and looking both of the people up and down.

"This is Wanda Maximoff."
He signalled to Wanda.
"And this is Pietro Maximoff."

'Great, hot guy is married.'
You thought.

"These are the twins I told you all about."
He said smiling. You mentally sighed.

"Ok, let's take them to meet the others."

"Oh and um.."
Clint pulled you aside.
"Pietro isn't the most social or nice person ever so... Be careful... He's a smart ass."

You raised a brow and chuckled lightly.
