Her mouth drops open in surprise at his request, and her eyes widen as she processes what he's asking her to do. Part of her wants to say no; it's not something she's ever done before, and she's not sure if she'd even know how. But another part of her can't help but feel aroused by the idea...and the thought of getting better marks on her tests is incredibly tempting.

"I-I don't know..."

She glances down at his crotch, noticing the obvious bulge in his pants for the first time. It's almost as if he's daring her to make a move; challenging her to take what he's offering. Her heart races and she feels warm all over, despite herself.

"O-Okay," she says softly, her voice barely above a whisper. "But...I don't want anyone else to know." She looks up at him nervously, waiting for his response.
