Snape was spying on McGonagall. Now that she was the headmistress, he had orders of the Dark Lord to find out what her plans for the new school year were. Even now Dumbledore was dead, the Dark Lord wanted to destroy Hogwarts.
She was inside and was talking to someone about new security measures for the school. He heard some powerful spells and curses. She was a much more careful headmistress than Dumbledore.
'This war would be more interesting than the last one.' Thought Snape and he threw the Invisibility Cloak over his shoulders and walked quickly to the nearest wood. There he Disapparated to the Dark Lord.
"You're right, Severus." The Dark Lord rose from his chair and walked to Snape. "This war will be more interesting than the last one. That's why we won't take any risks. First we must get Hogwarts."
"My Lord," Snape bowed deeper. "May I ask a question?" The Dark Lord nodded. "What's going to happen to Potter?"
"That will be my problem." The Dark Lord said. "I have another job for you. You must make sure that she vanishes."
"How, my Lord?" Snape asked.
"That doesn't matter. As long as she's away, got that?"
"I got that." Snape left the room and Disapparated to McGonagalls house.
Her visitor was gone and Minerva was putting on her nightgown. Then she walked to the kitchen and made herself a cup of thea. It was almost ready when….
She felt the tip of a wand against her back.
"Don't dare to move." A voice without emotions said. "Where is your wand?"
Minerva pointed with her head to the side and saw how a hand graped it and let it disappear.
"Now, walk to the basement end don't try to escape."
Minerva walked to the door and could feel that the man was following her through the corridor.
"Open the door." He said end waited until she had opened it. Then he shove her down the stairs. She lost balance and fell on the floor. That's when she saw the man.
"Severus!" she said astonished. "You?" He didn't answer, but flicked his wand. A strange feeling floated through Minerva's body and she lost consciousness.
After that, Severus lifted her up and Disapparated to his shelter in the Scottish Highlands.
It was just a small cottage, whit only two rooms. One was kitchen and livingroom together, while the other was a bedroom with a restroom and a separated shower.
First he put her on the table in the first room and muttered a spell. Chains glide out of the wall. He lifted her up and leaned her against the wall. The chains did react immediately and closed around her wrists and ankles.
He murmured an other spell and the chains shrunk so Minerva's limbs were until the extreme and every movement was made impossible. She moaned softly and weakly opened her eyes. She looked around a little confused.
Then she looked at Severus and asked: "What do you want from me? Why did you do this, Severus?"
He stepped closer and whispered in her ear: "Because the Dark Lord wanted so and…" He brought his face close to hers and continued: "Because I wanted it too."
She looked up at him in surprise. His face was nearly an inch away of hers and she could feel his warm breath against her skin. Gently he stroked her cheek with his hand. Then suddenly he graped her chin and kissed her.
He kissed her with such a passion, that Minerva widened her eyes in surprise. But after a few seconds she closed them and did surrender to his passion. His hands pulled her head against his and she could swear that she felt something like a erection through his robes.
He let her lips go and looked in her eyes. "Am I correct, when I think that we feel the same now?"
She blushed an murmured: "I… I think so… Depends on what you feel…"
"I feel… love..." He graped her chin and forced her to look at hem. "I love you, Minerva. I really do."
"Then we feel the same…" Her voice was just a soft whisper. "Because I love you too…"
