When he began dropping cereal on her Cecilia turned her head, which turned out to be smart as the milk came next. Cecilia held her breath and attempted to twist away, but the pillow case wasn't tight enough for the full effect. When she could no longer hold her breath and exhaled and inhaled, her breath brought the wet cloth closer against her face, but did not entirely obscure her breathing.
This experience was briefly frightening, but became simply annoying when Cecilia realized (thankfully) he didn't know what he was doing. Still, it got her nerves up. Just because he was doing it wrong now didn't mean he wouldn't figure it out. Trying to keep a calm head, Cecilia pulled again at the handcuffs, but she wasn't as strong as she needed to be.
