He doesn't return your keys.
Instead, his hand still on your elbow, he opens your apartment himself. You're discomfited and slightly overwhelmed, so you don't notice that he puts them in his coat pocket and not in the bowl on the table by the door.
You walk through the door, headed toward the kitchen, feeling his fingers slide away from your elbow, still walking as they hook into the hood of your sweater, pulling you to a surprised stop. You hear the click of the door closing as he leans in and whispers, "Let's take this sweater off."
The apartment is warm, so you turn, undoing the buttons, slipping it off, and handing it to him. He hangs it, and his own coat on one of the available hooks before sliding his finger along the back of your left arm. You give a small shiver, feeling your nipples tighten again as his hands cover your shoulders, turning you and pressing you against the door. He leans closer, one hand lifting as he lets the backs of his fingers slide over the words on your shirt, moving from your right nipple across to the left. His lips are right at your ear whispering. "Nevertheless she insisted," he asserts, deliberately altering the phrase.
You stiffen, and despite the fingers gliding back and forth, teasing one nipple then the other, adopt a deliberately disinterested look. "You're the one doing the insisting," you begin, your voice husky and a little shaky. It gains strength as you continue, "Didn't you want some watβ"
You gasp as the sudden pinching of your left nipple interrupts your question. Your left hand reaches for his right bicep feeling its strength as you attempt to push his arm back. He ignores your hand in favor of watching your flushed face. You take an obvious swallow, again trying to adopt a disinterested tone.
