Becoming My Brother's Girlfriend

As he lay there in his bed jerking off, everything made sense. He often got jealous when he'd see some guy putting his arm around Tori, or when he'd hear guys at school say how hot she was. Could he have secretly been in love with his sister and not know it?

"Hmmmggggg," Derrick was coming to his orgasm quickly. He had pictured himself with his cock buried deep inside Tori's cunt as she wrapped her legs around him and then he came back to reality as soon as he felt his warm cum drops hitting his skin. He'd made such a huge mess. His stomach was covered by his spunk as well as his hand.

He closed his eyes trying to regain his strength back. His breath was heavy and his heart was pounding from his wonderful orgasm. Finally he opened his eyes once he heard noises in the living room. He heard voices and rushed to grab some tissue to clean himself off.

"So you're going to be a freshman next year huh?" Derrick heard Josh's voice.

He had tossed on a t-shirt and shorts before heading out to the living room. There stood Josh and Tori. Derrick almost felt his cock harden again seeing the fact that Tori was wearing such short little cotton shorts and a tiny t-shirt that showed her flat tummy. Yet some anger went through him knowing that Josh was getting to see her almost half naked.

"Hey Derrick. I was just talking to your girlfriend. I found her fast asleep in my room. I figured she'd be sleeping with you."

Derrick froze for a moment not knowing what to say. He looked at Tori and she was just smiling wickedly.

"Well we did sleep in the same bed but Derrick kept moving and I couldn't sleep so that's why I went to the other room." Tori explained.

Derrick felt somewhat relieved to have his sister save him. "Yeah and Tori likes a big bed."

Josh scoffed. "Yeah I like big beds too. These cheap apartment owners think all college students do is study. That's why they provide us with tiny twin sized beds."

Derrick couldn't take his eyes off Tori. Her long hair was a mess and those tiny shorts showed off her sexy tanned legs. He could also see her nipples poking from her sheer t-shirt and knew Josh was looking as well.

"Well Josh did you get to get what you needed?" Derrick asked trying to rush Josh out.

"Yeah I did. Hey listen you two, I'm having a party tonight well, we are having a party I mean. Stacey and I. And maybe you two can come?"

Tori looked at her brother's reaction. He didn't seem too thrilled. "We'll we might. We had other plans." She stated.

Josh shrugged. "Oh ok. Well come by if you like." With that he left carrying some things in a box.

After Josh left, there was a silence in the room. An awkward silence.

"Derrick are you OK?" Tori asked concerned.

He just looked away. "Yeah I'm fine. I'm sorry about having him come in here. I just wish he would get all his shit out in one day. I think he's just doing it on purpose to talk about Stacey and get me pissed off."

Tori walked closer to her brother putting her hand on his shoulder. "Hey bro don't let him get to you. Look I tell you what. Let's go to that party tonight and show them that you could care less if they are together."

Derrick looked into his pretty sister's eyes. "You think that's a good idea?"

She smiled. "Yup! I sure do. I will try to be the best girlfriend I can be."

He felt himself blush. "Alright then. I guess we are going to a party. Now get dressed so I can treat you to some breakfast."

They went out for breakfast and later on Derrick took Tori around campus just to show her the different buildings and the best spots to hang out. She was having a wonderful time with her brother, better than she'd had with any other guy. It was just so easy to be herself around him.

Derrick loved hanging out with Tori. She made him laugh and definitely took his mind off Stacey. He hadn't even thought about another girl since Stacey but now Tori seemed to be taking control over him. That day she wore a short blue colored summer dress with spaghetti straps that went just above her knee making her look sexy and lady like. Shiny blue pins that matched her dress pulled her long dark hair back. Derrick could only imagine what her body looked like naked.

After a nice quiet lunch at a small café and some more sight seeing around the college town, Tori and Derrick headed back to Derrick's apartment. It was almost eight that night and Tori started to get ready for the big party that Josh and Stacey were hosting.

That night Tori made sure to dress up as sexy as she could to piss Stacey off. Deep down she was really dressing up for her brother hoping to get him hard and tease him. She'd only brought little clothes with her so she'd have to find something nice to wear. She'd brought her short blue jean skirt and a blue and white tube top. She put her hair up with just a few strands hanging down her pretty face.

Derrick was busy tying his shoes when Tori came out of the bedroom looking so stunning. Her long tanned legs were showing so nicely. Derrick couldn't help but whistle at her.

"Wow sis you look nice! A little too nice shall I say?"

She blushed and turned around showing her brother a great sight of her firm little ass. "Thanks bro. I hope to look as pretty as your other girlfriends in the past."

"Well you look even prettier than them sis." His eyes were glued to her beautiful body. The tube top barely covered her belly button letting her flat tummy to be admired. The little blue naval ring gave her such a sexy look as well.

"Shall we go?" She asked smiling.

"Yes." The left together feeling somehow nervous.

They arrived at the party near 9 o'clock. All of Derrick's friends ogled Tori. Derrick felt proud having such a gorgeous girl with him. Deep down it turned him on that no one knew it was his own sister.

"Well Derrick! You made it!" Josh said loudly making Stacey turn around. "Hey Stacey? Come here. Let me introduce you to Derrick's new girlfriend."

Tori saw the pretty tall blonde girl approaching them. She noticed her brother kept cool.

"Stacey, this is Tori, Tori this is Stacey." Josh introduced them with a slight slur as if he'd been drinking.

"Hi. Nice to meet you," Stacey answered sheepishly.

"Very nice to meet you. I heard a lot about you," Tori replied sarcastically.

Derrick put his arm around Tori and they both took one last look at Stacey and walked away. Tori turned around to see Stacey still eyeing them as if she was dying of jealousy. Derrick couldn't help but laugh once they headed out. They walked out laughing and holding hands.

"Oh man that was great! Did you see the look on her face? She was so shocked that I'm not sitting at home being miserable over her," Derrick said gleefully.

Tori smiled at her brother put her hand on his face. "I love being your girlfriend." The words just slipped out of her mouth.
