not really sure

You stare at Hanna, dumbfounded, as her tongue moistens your cockhead. You only considered her as your buddy-- nothing beyond friendship, yet here she was, teasing your cock with her tongue. "Do you still consider me boyish?" she repeats her question.

You try to maintain an expressionless tone as you say, "I'm not really sure," but your face betrays you.

Hanna realizes this and increases her pace. She pauses again and asks, "And what will I do to make you sure?"

"You don't have to prove anything to me, Hanna."

She shoots you a somewhat angry look. "I'm not a boy!" Then her expression lightens as she starts to unbutton her blouse.

"Please not here, Hanna," you whisper loudly. "This is the library!"

"Then follow me," she says with a tone of authority, as she heads toward one of the carrels.

You realize you cannot refuse her when she sounds that way, but you are also fearful of getting caught violating the rules.
