You'd had a tough week with coursework and wanted to take some time off, but had been told that your cousins were coming over for a visit. You'd shuddered then, and had also been frustrated at your sister and Maria gossiping throughout the day, a sentiment Samantha shared. In fact, the two of you almost cheered when the two girls agreed to go shopping after lunch, with the promise that they'd be out for several hours. You and Sam sat down and watched TV for a while until she sighed. You asked her what she felt and she told you that she'd had a bad week too.
"Sam, it wasn't too bad was it?"
"Sorry, but it was. It sucks too; the worst part was on my birthday."
"Hey, sorry we couldn't show."
"That was only part of the problem..." And here she went into great detail about her woes, and, although only some seemed like legitimate causes for concern, you knew what it was like when YOU were 13. You put an arm around her shoulder and gave her a quick hug, then, with your arm still around her, you gave her some words of advice which she listened to, with a cute smile on her face. "And, Samantha, I have to say, you are the sweetest, loveliest girl I know, and I know this is all hard for you." She leaned in and hugged you again, then pecked you on the cheek with a shy smile. You grinned and placed a hand on her cheek, then kissed her forehead. She giggled and muttered "You're good; I would totally go out with you right now!"
"Why don't you?"
"Seriously? You're my cousin! You're 5 years older than me!"
"So? I didn't want us to live happily ever after together, but, if we were a couple, what would you do?"
She blushed and whispered, "I always thought you were good-looking..." You made her look at you and whispered "What would you do if I did this?" And kissed her on the lips. She was clearly taken aback, but began to kiss back, your arms enveloped each other until you finally broke apart. She wore a huge grin as she said "I guess we could pretend to be a couple, when no-one's around..." You smiled gently and placed a hand on her thigh, dangerously close to her pussy. She seemed surprised for a split second but your face made it seem completely accidental as you asked "Sam, I wondered if we could take a look at something?"
"O-okay?"
"We are acting like a couple aren't we? Because I've always wanted to say that you are smoking hot." She blushed and fidgeted with her leg, as if hoping you'd touch her area.
"Y-yes!" She almost seemed to be hyperventilating, you thought, as you looked at her slightly heaving breasts. "What do you want me to look at?"
