Hermione loses

"Stay back." Hermione barked at his advance.

"What are you afraid of, Granger?"

"I'm not afraid of you."

"Too afraid to make a bet?"

Hermione scowled at him, shivering in spite of the heat of the fire, the warmth of the invisible robe. "I'm not afraid. What is this stupid bet anyway?" she spun around, hiking up the panties, and tucking her nipple away, wishing she could run to the wardrobe for her school robes without looking afraid.

"Simple. I bet I can prove that you like it" he took a step up to her,

wrapping his arm around her waist, pushing himself up against her. Hermione felt something hard poking her in the backside.

"And how are you going to prove that?" she asked, forcing herself not to flinch, trying to steel herself to stop shaking. She felt his lips on her ear, "You'll tell me I'm right."

"That's it?" Hermione thought. "That's too easy. There must be a trap."

"And what happens when I win?" she said fighting the urge to slap his hand which was creeping past her bellybutton.

"I take the crecious curse so I can never tell anyone."

That struck home, hard. Malfoy would assuredly run out and tell every Slitheryn what had happened, and she knew she could never live with the shame of that. Trap or not, she knew then and there that she would have to play along. She put a hand over his just as it was about to slip down the front of her panties, "And what happens, hypothetically speaking, if I lose."

Malfoy smiled. He knew exactly where he had Hermione. "That's just part of the bet, isn't it Granger?" He flicked his wrist and she moved her hand, chastised, and dexterously slipped his hand into her panties. You lose just by agreeing to the bet.
