Mina frowned as Bethany rejected her. "Am I not pretty enough...?" She whispered, but shoook her head. She squeezed Bethany's hand a bit harder as they went to join the others. "I'm sorry Ms. Fisher... I'm being dumb..." She then came up with a plan. She had to repay  Bethany for her kindness. And the best way to do that would be to give her cock release. "Mmm... After the tour, can you show me to my room, Ms. Fisher...? See, I tend to get lost easily, and I'd really appreciate it, so please?" She begged. That way they'd be behind closed doors. She was sure Bethany just wanted to keep a good reputation with the headmistress. She leaned against Bethany as they walked together.
