Sniper's scent was so appealing to you. His cologne was just so him, it was hard not to find it comforting--that's exactly why you ended up snatching his jacket. This leads to your current state--laying in your bed, his jacket wrapped around you, your face nuzzled into the collar. You hadn't thought of what would happen when Sniper found out until he was standing over you, peering down at you as you meekly peaked out of your spot.
