Disclaimer: look the previous chapter.

A/N: I'm sorry for being so late updating... I needed some time to think on the plot (and also to study my exams) but the next part will come sooner. Thank you to everybody who reviewed the previous chapters, I love you like my story... .. . Here's the third chapter:

Her sin - 3 - The beginning

"Is this why you didn't want me to know about the father… because it's Albus?" asked Poppy Pomfrey after manage to take Minerva away from the crowd of the staff that was congratulating them for the engagement Albus had announced during the breakfast the next morning.

Minerva didn't want to answer her friend, she didn't want to lie her, but saying her the truth would mean bear her questions again, and she didn't want that either.

Everybody in the school knew they both had been flirting since Minerva had began to teach in the school the year before and, as well, they'd must notice how much closer they'd became since the end of holidays. Telling that baby wasn't his would be as shout to the winds that she was a cheap slut. Everybody would think she was that kind of witch who likes go from man to man… and she wasn't.

Fortunately Albus appeared suddenly behind her and rounded her waist with his arms resting her hands on her shy belly.

"She wasn't sure of my reaction" told him to the nurse "That's why she didn't want to tell me…" He removed some of Minerva's hair and placed a soft kiss on the back of her neck that made her shiver. Then Poppy ran away giggling shyly and Minerva turned back.

"Why did you say that? You aren't…" but Albus placed a finger on her lips.

"If you don't want anybody to make questions about the father, then let them believe I am him…"

"I don't like lying people, Albus…"

"You needn't… it's me who's lied to Poppy, and I will lie to anyone for you…"

"I'm not sure if I should thank you for this, or not…"

"It's enough for me if you give me a kiss" he smiled and Minerva stood on her tiptoes to kiss his lips sweetly. Then they left the dinning room at the same time that another teacher did… .. .

"What are this news you have for me…" asked a strong voice in the dark room of an old house in the middle of the forest.

"Dumbledore's getting married, my Lord..." answered the trembling voice of a young man.

"Really? And who's the fortunate lady?"

"The women he hired last year for the transfiguration subject… Mrs… MacGuilly… or something like that…"

"McGonagall… idiot, it's Minerva McGonagall… and she can't marry that decrepit old man"

"Why not?"

"Because she is mine…"

Fourteen years ago… 1943… Hogwarts…

"Professor… Who's the new boy who's coming tonight?" asked a young dark-haired girl with tartan clothes.

"It's a sixth year, but it's a genius in my class… Look, it's the boy who's right coming in, let me introduce him to you…"

The professor took her arm and walked to the room's door, where a tall thin boy was standing looking at the people eating and talking around.

"Good evening, Mr. Riddle, did you have any problem to find my rooms?"

"No, Professor Slughorn… your indications were right. I just wanted to finish my homework before come…"

"Great… good boy. Let me introduce you to this pretty lady…" Horace Slughorn pulled the girl between them and she blushed "Mr. Riddle, this is Mrs. McGonagall. She's my favorite one…" he whispered at the end.

"Nice to meet you" said the boy shaking his hand with hers.

"Nice to meet you" answered her when the professor had left to talk to someone else "Don't belive Mr. Slughorn… he says the same of everyone in here…"

"Well… you look pretty to me…" said him "…and intelligent, too"

"My name's Minerva" she said sweetly giggling.

"I'm Tom"
