Pregnant by my Sister's Fiancé

Prolouge:

Jenna had stayed back to help her sister's fiancé with his truck. Jenna had never been the girly girl, she was the tomboy. Jenna was the one who had beach blonde hair but wanted black or brown. Jenna was the one who would rather fix a car than her hair. Complete opposite of her older sister, Jazmine.
"Jen?" Ashton looked at Jenna, concern flooding his eyes.
Jenna shook her head and smiled. Ashton really was the best brother-in-law-to-be that there was. He always watched out for Jenna. Jenna wasn't going to lie, she liked Ashton. He was Jazmine's fiancé, though. She didn't want to ruin that.
"I'm fine. I started to daydream." Her blue eyes were brighter than the clear sky above her. Her dimples showed as she smiled.
"How about you come in for a drink? It's hot outside." Ashton smiled and Jenna nodded. They walked to the house. "Lemonade or coke?" Jenna gave Ashton a 'really?' look and Ashton chuckled. "I know, coke for the princess." He opened the door to the house and the air conditioning hit them like a pile of bricks.
Jenna sat on her sister's couch, some yellow and red plaid and polka dotted couch from the 70s. She knew that Ashton and Jazmine had shared many...romantic, for lack of better term, nights on this couch. She also knew, Ashton was the only boy who would never cheat on her sister. The others all had within the first month. Ashton was the type of boy who always put his lady first. Always treated her nicely and never tried to start fights.
"Jenna, your sister said they aren't going to be back for another two hours. Something about a wedding dress mix up and they can fix one there. I don't know." Jenna smiled as Ashton looked at his phone confused.
"Well, the truck is fixed. What do you want to do?" Jenna sat on her hands and put her legs pretzel style.
"We can do something I have been wanting to do for a while..." Jenna raised her eyebrow. "You know how, when we first met, three years ago, I told you I liked you, by the big oak tree?" Jenna nodded. She remembered it clear as day. "Well, that day, I wanted to kiss you. Wanted to hold you in my arms forever. You wouldn't let me. I wanted to just make love to you all day and night." Jenna tried to hold back her surprise. Ashton moved right I front of Jenna. "And, I knew I couldn't. You were fifteen, I was 20. Now, we could." He leaned closer to Jenna.
Jenna pushed him away. She would have in a heart beat! Just, one problem, he was marrying her sister in two months!
"My sis-" Ashton cut her off by placing his lips gently on her own. She felt as though she was in Neverland. As though, nothing else existed.
Soon enough, their clothes were everywhere and Ashton was lined up at her entrance. Jenna bit her lip and nodded. Ash gave her a small kiss on her forehead and slowly pushed in. Jenna was a virgin, it hurt and tears started to form in her eyes.
"I will go slow. Promise. Tell me when you want me to move." Ashton held her hand and kissed her tears away.
"Go."
Ashton went slow. It soon became bearable and all you could hear was their shallow breathing. Ashton came inside Jenna. Ashton kissed Jenna and laid beside her.
"Jenna Collins. Remind me to break up with your sister."
After a half hour of YouTube and food, they heard a car pull up. Jenna quickly threw on her clothes and Ashton did as well.
"Babe!" Jazmine ran to Ashton and he twirled her around. "I missed you so much!" She kissed him and it hurt Jenna. Hurt her in a way she could not describe. "I love you."
"I love you more."

-A/N: This is going to be a little different. Ashton is amazing and I just thought the idea when someone was talking about a wedding and I thought 'PREGNANT MAID OF HONOR!' Then, I got an even better idea! 'SISTER GETS PREGNANT BEFORE HER SISTER'S WEDDING! BY HER SISTER'S FIANCÉ!' So, hope you enjoy. :) xx-Tessa--
