Tara was into that sort of thing. Even though the man on the cover probably didn't exist, she was still having some thoughts about him. She probably looked a bit distracted when he mentioned 50 Shades of Grey.
She started paying attention again when John started reading the novel, pushing herself up to be able to read along with him.
When he stopped reading and started laughing, Tara scowled (probably a little too dramatically) and snatched the book out of his hands. "Don't stop!" she told him, not realizing there was a perfect that's what she said right there. "It was just getting good!" and another. She kept the book open on that page, and began reading through her oversized aviators.
If he could see her eyes, he'd notice they were widening while her eyebrows lifted. Very interesting indeed.
