Brothers best friend *mauraders era*

Ch.One

Alexa potter stood in her bedroom as she stood packing her trunk for hogwarts, she rolled her eyes as she heard her brother James and his friends from his room.

Alexa was close to her brother. She was the female marauder after all but she didn't agree with the bullying that they got up to. Alexa sighed to herself as she finished packing and sighed, she sat on her case and sat there for a moment. She was returning to go warts but she knew that everything had changed over the summer.

She was returning for her fifth year but over the summer she had found herself sleeping with Sirius back, her twin brothers best friend and it wasn't the first time either. Alexa knew it was a mess. Alexa started to change as she heard a knock at her bedroom door. She frowned to herself as she walked to the door we she saw Sirius. She looked to him and smirked

"I think your lost sirius, my brothers room is the other side of the house" Alexa said as Sirius looked to her and smirked

"oh I'm not lost at all, I wanted to see you" he said as she grabbed him and pulled him inside and closed the door

"why would you want to see me?" She asked as he looked to her and smirked

"Oh I think you know why" he said as he edged towards her, he grabbed her waist and pulled her close and kissed her. All of a sudden, she kissed him back as passionately.

There was a fight for dominance as he lifted her up as she wrapped her legs around his waist. She moaned as he ran his hands up her thighs causing her to moan as he lead her over to the bed and dropped her onto it.

Alexa looked to him and smirked as they stripped off, he ran his hands across her naked body and smirked, he got between her legs and pushed into her causing her to moan as he started to move in and out of her.

Alexa moaned as she dug her nails onto his back, she knew what she and Sirius were doing was wrong and how if James found out it would ruin everything and possibly Sirius and James friendship but Alexa also knew that it also felt so right and that she couldn't resist herself when it came to Sirius.

Alexa moaned as she felt herself reach her high as Sirius followed. He rolled over on the bed and lay next to her and smirked

"you really are risking us getting caught" Alexa said as he smirked

"I didn't hear you say no" he teased as she looked to him and rolled her eyes

Alexa lead Sirius out of her room as they headed towards the platform as James frowned as he walked down the hall

"has he been winding you up again lex?" James asked as Alexa looked to her brother and smiled

"yeah you could say that" Alexa said as she looked to Sirius and smiled. She knew there was a lot at risk if James found out. Alexa watched as Sirius walked off and sighed as she ran a hand through her blonde hair as she saw her younger sister rose walk over to her

"what?" Alexa asked as rose looked to her and rolled her eyes

"I'm not as stupid as James is and I know that Sirius wasn't winding you up" rose said as Alexa looked to her sister and frowned

"I don't know what your talking about" Alexa said as rose looked to her and smirked

"you can say that but you and I know there is something going on with you And Sirius and let's hope that James doesn't find out as he won't be happy about it and you know it" rose said as she walked off.

Alexa looked after her and frowned to herself. She knew that no one could know over her and Sirius and that she was going to have to be more careful

Alexa sat in the train compartment with lily and rose as James and Sirius walked in "lilykins. Did you miss me." James asked as he wrapped an arm around lily.

Alexa Rolled her eyes at her brother as she made eye contact with Sirius and smirked to herself. She knew that no matter what happened this year at hogwarts that no one could find out over her and Sirius but that was easier said than done.
