Loki is your husband since centuries ago in Asgard
Tony bought some card games online, game called 'Drunk Desires', a couple drinking game, There were two colors, white and black cards, the white was normal dares and the black was naughty dares, if you don't do the dares, you need to drink once or twice
Tony picked a white card, it said: 'Guess your partners favorite moive or drink.' of course, he guessed Pepper's moive correctly. Loki's turn, as the god of mischief, he of course picked the black card
The card read: 'Go to the bathroom and take a naughty pic and sent it to your partner or drink twice'. You guys didn't know what was his card, so he went to the bathroom and the others kept playing
You phone's notifications rang and Loki sent you a naughty naughty pic, he came out the bathroom
