Erica plagued his dreams and his thoughts.

When Severus was working in his office he was able to shove her to the back of his mind, but at night, she slipped out of the shadows.

" It's just your feeling guilty for what happened a week ago, and the way you treated Erica after the mind-blowing sex you had with her … you told her that it wasn't that great, while we both know it actually was the best sex you had in your entire life!" the little voice of his conscience suggested in a dark, taunting tone.

Severus huffed " Ohhh … shut the fuck up … What was done is done … She's Potter's sister … spoilt and arrogant to the core … and she's not even that attractive, so stop bothering me would you?".

No matter how many times Severus told this to himself he knew it wasn't completely true.

Erica's firm, curvy body pressed against his, taking, demanding everything he could give.

Her moans, pants, and screams of ecstasy were looped in his mind.

Severus would wake in the middle of the night, aroused beyond bearing, his cock unbelievably hard and aching.

Severus sat at his desk, sweat breaking out all over his body, as he replayed that night in his mind.

Shit, he could not work like this!

He tore his trousers open, wrapping his hand around his shaft, falling into a quick rhythm as he imagined Erica, riding him, or better yet sucking him off, on her knees.

Cupping his balls with his other hand, Severus groaned as thick white jets of sperm spilled in his hand .

" Am I losing my mind over Erica? Why now? " he muttered while cleaning and tucking himself in his trousers.

Severus would not admit it even to himself, but that night with Erica wasn't easy to forget, despite his various attempts at doing so, Erica was slowly but surely replacing the image of Lily inside his head.

And that worried him immensely.

" That's your third dead plant this summer, Rica… Losing your touch?" commented Hermione Granger looking at Erica, who was intent in lugging a huge trash can.

The bushy haired woman caught up with her friend and helped her setting the can beside a very dead bush.

Erica scowled at her and said " it's been a dry summer…"

Hermione sighed " oh, yeah I forgot …"she said glancing at the small garden around her friends home.

Ever since Hermione met Erica, she had noticed that her friend seemed to have a fixation for plants and gardens.

Ron reached the two women and kissed Hermione on the lips before turning to Erica.

" Ehy, Erica I heard that you'll be going soon to America … We will miss you … when do you plan on going?" asked the redhead looking at his friend who simply shrugged.

" I have the flight to New York in three weeks… take care of my babies for me, water them every day, make sure they get enough light and …" Erica began to list, she loved her plants so much that she called them ' babies'.

The fact that her aut Petunia used to make her do chores and garden, water, and take care of her plants had made Erica fall in love with gardening in general.

It had been the thing that she preferred, just to escape her dear relatives abuse.

" Ok Erica, we will .. don't worry …" said Hermione cutting her off and wrapping her arms around the raven haired girl, who simply huffed irritably.

No one loved plants like she did.

Later, that evening the three friends seated themselves on the sofa, it was Thursday night and they had developed a tradition: pizza, and a movie or two in front of the television.

Erica was enjoying the movie while Ron and Hermione were in a slogging session, when a faint cramp tightened her belly momentarily and Erica had to shift, drawing her knees to her chest.

Over the next hour the cramps worsened, Erica straightened her legs " I'm sorry guys, but I think I need to go to bed" she said trying to keep her voice level.

" Are you okay?" asked Ron, and Erica simply nodded while Hermione had a worried expression on her face " Are you sure sweetheart?" asked the auburn haired girl.

" Yeah. Just need to get to bed …" Erica replied, trying to keep the crossness from her voice.

She was feeling cranky without a reason, lately .

She pushed herself to her feet but was helped by Hermione " Are you getting sick ? Erica, what's wrong ?" asked the girl, her worry increasing.

Erica looked at her and then said, very slowly, as though talking to a small child " Think about it, Mione.

What makes a girl very tired, very cranky, and makes her belly cramp?"

Understanding dawned in both her friends eyes, Ron blushed dark red " ah, mmhm… ok, you need anything?" he stuttered.

Erica amused by her male friend discomfort smiled " Yes, I need a heating pad and my bed. I can handle it myself. Go home guys, good night." she said heading for the stairs.

Erica didn't glance back at the noise behind her, intent on getting that heating pad, and her bed.

Early next morning, Erica climbed out of bed, her body aching.

Her period had never bothered her like this before.

She had started to worry a little the past week, especially after what happened with Snape. But fortunately it was not the case, right?

Erica stood staring at her reflection so pale and drawn, and felt like crying as she remembered what he had said to her.

Snape had been so kind when he met her but then, after their passionate sexual encounter he had hurt her badly, he had been determined to show her that she meant nothing to him and Erica wasn't sure of what she would do now.

" I only used you … you weren't that great of a lay… I had better!"

Should she tell James ? After all he and Snape had been friends.

But another part of her, the abused part told her " you can only count on yourself … Others will only judge you, like your Aunt Petunia and Uncle Vernon …" and her brother would have killed Snape.

Erica shook her self determinedly, she had her trip to America to think about and her brother had organized a goodbye party for her in two days, which these thoughts she smiled and exited the bathroom determined to put that night behind her and start over.

Nearly three weeks had passed since she had arrived in New York, and Erica wasn't feeling good.

The light period had passed, but fatigue and general mood swings hadn't.

Erica was sitting in the doctor's office, and the moment he confirmed her worst fears she couldn't believe it " i can't be pregnant… I had my period five weeks ago … and i had sex with the father over a month and half ago …".

The doctor smiled and said " You're pregnant Miss Potter, the test is without a doubt positive. You probably had some very light spotting. Some women have that the first few months of the pregnancy."

Erica licked her dry lips " will that hurt the baby?" she asked worried.

The doctor smiled softly " I'm sure everything is just fine. You're young, strong and healthy miss Potter…" he paused and stared at her sympathetically " you weren't expecting this … There are options …"

Erica cut him off " No! Expecting it or not, it's my baby!" she hissed, her hand flying protectively to her still flat stomach.

" And the father ?" asked the doctor, Erica's eyes filled with tears thinking about Severus's reaction, and her brother's too of the news

" It doesn't concern him! It was a fluke! He doesn't want a family!" she quickly said trying to regain control over her emotions.

" Being a single mother is a though job, miss Potter… " the doctor said gently, but Erica was determined .

" There's not much choice… I won't force the father of this child, into something he doesn't want. Plus I'm financially able to provide for the baby"

It was easy, Erica realized, to say it. The doctor beamed at her happily.

Severus was sitting across James and Lily while listening only halfheartedly to their conversation, his eyes were trained on his red haired best friend and he couldn't help but compare her to Erica.

Lily was beautiful, but as soon as Severus visualized Erica's face he realized with a start that he wasn't feeling the things he had felt a month ago for Lily.

" Severus, are you all right ?" asked James looking at the raven haired man who had a strange expression on his face " uh … of course Potter … I'm fine, just thinking…" replied Severus none too gently while Lily kicked him from under the dining table glaring at him softly.

Severus sighed " Sorry, it's just have my head in the clouds …" James smiled softly, when he was in hight school he had been a bully to Severus.

But after he and Lily had begun to date, James felt sorry for the way he treated his wife's best friend, James thought now was the time to apologize for ruining Severus's life.

" How is Erica, James ? Last time i saw her was three weeks ago before she went to New York …" said Lily turning to James, Severus felt his heart rate increase but tried not to show it as he asked " Who's Erica?".

James smiled quite fondly " she is my little sister …" Lily smiled too " Pity, you didn't met her Severus … She is very kind, funny and intelligent. But she has suffered terribly …"

Severus gulped as he felt guilt rise in his gut at the thought of what he did a month ago to Erica, he suddenly felt ill.

" I didn't know you had a sister James …" Severus replied somewhat nonchalantly and James expression sobered

" I didn't know myself until an year ago … you see. My father was a very hard and strict man, and on top of that he was maschilist.

He thought that the Potter line was to be brought on by a male heir.

Ten years after my birth my mother found out she was pregnant and it was a girl …"

Severus felt a cold chill down his spine, ' oh, no…' he thought suddenly as a very bad feeling formed in his chest.

" A year ago I found a letter my mother wrote me in which she explained what my father did : as soon as Erica was born, he sent her to live with a couple in Little Whining, the Dursley.

When I found Erica, well … lets say i saved her from those monsters …" continued James, completely ignorant of the guilt Severus was feeling the more informations James was giving him.

" Why… did you have to save her from her family … they probably loved and spoiled her" James glared at him " I would hardly call, beating a little child, making her do every kind of chore, starving her of food, making her live for the first ten years of her life in a cupboard under the stairs, making your son bully her at school and at home, Love… and the worst is that those monsters were paid by my father to do those things to my sister!" James screamed and Severus felt ill .

" I'm sorry … i thought … i have to go …" stuttered Severus, raising from the table while Lily looked at him worried " Sev ! Wait, where are you going ?" she asked following the raven haired man to the front door.

Severus sighed softly " I'm sorry Lils … i need to go home … I… sorry" Severus kissed her cheek and began to walk in direction of his home.

But a voice stopped him " Severus, wait …" it was James, who ran to catch up with him .

" Sev, look. I'm sorry for yelling, but whether i think about what my sister had to suffer just because my father didn't want her … well … it's hard."

Severus felt a giant fist around his heart squeezing it hard and just nodded " I'm the one who's sorry James, I thought …"

Severus realized he hadn't the guts to tell James what he did to his sister, James would kill him!

James put a hand on his shoulder " Severus … I'm sorry… for the way i treated you in High school, I was an arse and i will never grow tired of saying i'm sorry for the bullying. I know you hated me, but i would like to make amends and start over with you… if you want"

Severus felt tears in his eyes and swallowed the lump in his throat, James was trying to offer him his sincere friendship, and he could not refuse.

Severus Snape extended is hand " All forgiven James… friends?"

James smiled and took his hand before pulling the raven haired man to him, hugging him softly " Friends Severus…".

Severus opened the door to his house with his head spinning. So much was revealed today, and guilt was eating at his gut.

' Soooo … are you feeling well ?' asked his conscience and Severus simply sighed too tired to even answer, as he went to the living room.

Suddenly images flooded his mind, images of him pressing Erica against the wall, her long body naked.

Of him going down on her, sliding his tongue inside her wet little cunt while she gripped at his hair and moaned.

Severus closed his eyes and breathed shakily, he could still taste her on his tongue, even after a month.

The images continued to invade his mind.

Him shoving Erica to the floor and thrusting his cock inside her body while she trembled from her last climax.

Pumping in and out of her body until she climaxed around him again, as he emptied his seed in her body screaming Lily's name.

Than the terrible things he said her afterward.

Severus's face became white ' oh, god… what have i done ?" he asked himself for the seventh time that day.
