Tony: It's always a surprise; he will come up behind you and scare you by hugging you. You'll squeal and pretend to be mad at him, and he will hug you tighter.

Steve: When Steve hugs you, he wraps his arms around you and you put your arms around his neck.

Bruce: Bruce doesn't like to hug you because he's afraid The Other Guy will show up and hurt you. It's an ongoing problem, and the cause of many arguments.

Clint: Clint doesn't really like to hug either, but when he does, he holds you close and kisses the top of your head.

Thor: Let's face it. Thor's huge. So must of the time when he hugs you, you have to remind him not to crush you. It's an inside joke with you two.

Pietro: He will run by you, sweeping you up bridal style and holding you close. You'll bury your face in his chest, and when he stops, you'll stay like that for a while. (I felt a lot of feels while writing this, I don't know why.)

Bucky: Bucky was afraid of hurting you at first but you convinced that you will be okay. He holds you close, and you rest your head on his shoulder.

Loki: Loki doesn't really hug you, but he will put his arm around your waist.
