Chris and his step-sister Tracy moved in together during the college years. Their plan was that one would work while the other would go to college. They would then trade off. That way, both could get a college education to go after their dreams. Chris had always gotten along well with Tracy, but overtime he found himself becoming attracted to her as they lived together. He would find his eyes instinctively following her around the apartment, studying the contours of her beautiful body. He always tried to remind himself it was wrong to lust after his step-sister, but he couldn't ignore the perfect shape of her ass when she wore her favorite jean shorts, the brightness of her blonde hair, or the fullness of her breasts when she wore one of her dresses for a date.
One evening, Tracy was getting ready to go out on a date with a guy she liked. She was wearing a black backless dress. She twirled in front of Chris and asked if she looked good.
"You always look good," he said. His eyes her velvet smooth, bare back. He longed to hold her in his arms and claw at her back while kissing her passionately.
"I'm just really nervous," she said, "Would you give me a quick back rub? That always relaxes me." She sat down in front of him, her back facing him. She pulled her hair to the side, exposing her back totally to him.
Chris replied, "Just a quick one." He placed his hands on her shoulders and his thumbs rubbed circles deep into her shoulder blades. Tracy felt the tension slowly working its way out of her shoulders. She thought about how nice and strong his hands were. His hands moved further down, and his fingers traced her ribs slowly and gently. Chris leaned in slightly and smelled the strawberry perfume she was wearing. He felt himself becoming hard. He wanted her badly.
Tracy continued to feel her body melt under his touch. She never felt so weak before in the hands of a man, let alone her step-brother of all people. "Could you go lower?" she asked with a hint of a moan.
Chris let his hands move further down, his thumbs digging into both sides of her lower back, freeing up all the tension. His body suddenly began to act on its own. He leaned in and kissed her neck, sucking on the spot he kissed until he left a slight red mark.
Tracy moaned and leaned back into him. "What are you doing?" she asked weakly.
"I don't know," he said. His hands slipped through the sides of her dress and massaged her breasts. Her nipples hardened between his fingers as he continued to trail kisses down to her shoulders.
Tracy slid back further into his lap, her ass grinding against the hardened bulge in his pants. She felt the length of his c*ck rubbing in between her ass cheeks, longing to be inside her. "This is so wrong," she said.
"We both need this," he replied. He slithered his tongue into her ear as he undid her dress. She stood up and arched her back, letting her dress fall off of her and revealing her stunning ass and p*ssy as she bent forward.
Chris stood up behind her and undid his pants. He tugged his pants and boxers down, revealing his hardened c*ck. He rubbed the tip up and down the lips of her p*ssy before thrusting it in. He went slowly at first. As he felt her tight p*ssy milking his c*ck, he began to thrust faster. She moaned wildly as his balls slapped against her.
Chris leaned forward and tilted her head to the side. His lips crashed into hers and their tongues became entangled as he f*cked her p*ssy aggressively. They moaned into each other's mouth as they climaxed simultaneously, his c*ck filling her up with his seed.
They continued to kiss passionately as he pulled out. "I guess you are going to miss your date," he said.
"I guess I am," she replied with a devious smile.
