– Title: SisterTrick – Gia Derza [Don’t Watch Me Change]
– Synopsis: Chad White walks down the hall to his StepSister Gia Derza’s bedroom, where she has just started taking off her clothes as she tries on an outfit while looking in the mirror. He watches voyeuristically through the partly open door to her room as he gets a perfect view of her undressing while turned partly towards him. She peels off her top to reveal her perky teen tits, & then takes off the lower half of her outfit to show off her firm butt-cheeks. The StepBrother moves slightly forward, just enough to get a better view without being noticed, & his hand grips at the door-frame with anticipation. Gia Derza pulls out an alternate clothing option & considers it for a moment. She tilts her head, pouting her face in doubt. To Chad’s delight, she twists around in place to consider it from different angles, flashing him even more skin in the process. Suddenly, Chad’s phone buzzes loudly with a received text message. Gia Derza yelps in surprise and recoils, pulling the outfit she’s holding towards her to cover up as much of her bare skin as she can. “Chad, Don’t watch me change!”, she whines. Her StepBrother lies & says he didn’t know she was changing, he just wanted to come & apologize for being mean to her earlier. She relaxes a bit but still holds the clothes up to hide behind. Chad continues saying he doesn’t know what the big deal is, it’s not like she was naked. They see each other in bathing suits all the time whenever they go to the water slides. Gia relaxes & says she guesses that’s true. Chad sees the clothes that Gia has laid out on the bed & asks her if she wants a guy’s opinion on which 1’s R the nicest. With a sigh, she says “Sure”. She holds up the outfit she was considering & asks what he thinks about it. He pretends to consider it, & ultimately tells her that he’s not sure about it. Gia Derza frowns & says “Yeah”, her neither, & groans & tosses it back in a pile on the bed. Chad asks what the big fuss is about the clothes, why does she care so much? Isn’t she just going out with friends? Gia Derza puts on a mischievous smile & says OK, Don’t tell Mom & Dad, but she’s going on a date tonight. Chad is surprised and a bit disappointed – She has a date & didn’t tell him? Gia Derza gets a bit hesitant & admits that he always gets jealous whenever she goes on dates. Chad can’t believe what he’s hearing & tells Gia Derza that he’s not jealous, just protective of her. “Fine, Whatever”, Gia says. There is a moment of silence between the 2. So…Is she going to have sex with her date?, Chad asks Gia out of the blue. Gia Derza complains that this is exactly what she was talking about, he’s getting jealous again, & besides, that is NONE of his business. & even if the guy wanted to, she’s never even had sex B4. StepBrother is shocked to hear this – But she’s had plenty of Bfs B4! Gia Derza replies sure, but she always took things slow in the past. But she admits that she is considering having sex with this new guy. Chad gets suddenly protective of her, she can’t just dive in like that, she doesn’t even know this guy. What if he hurts her, or expects her to do things she’s not comfortable with? Does she really want her 1st time to be with a complete stranger? Her 1st time should be with someone who she trusts. Gia Derza gets even more self-conscious and says she doesn’t really have anyone in her life like that right now, all her other friends R pairing up or going off to college. Chad says… Well, what if he showed her a thing or 2? Gia Derza reacts with shock, how can he even suggest that? She’s his StepSister! Chad says defensively that he’s just trying to look out for her, he cares about her & doesn’t want to see her get hurt. Besides, he rationalizes… “Technically, they’re not related, so if it helps she could just think of him as her very good friend”. Gia Derza frowns & says it would just be too weird. Chad says it doesn’t have to be – He could just show her a couple of moves so that she’s not going in clueless. Like what? Gia Derza asks incredulously. Chad tells her he could at least teach her how to give a proper HJ. That way if she’s ever with a guy & doesn’t want to take things further, that’s a great way to cool things off without making him feel blue-balled. Once a guy cums, he explains, he stops caring about sex for a while. Gia Derza says that that still means she’d have to touch her StepBrother’s… U know. Chad rationalizes that it’s just hands on skin, same as if she shook his hand or gave him a backrub. Gia Derza admits that that DOES make it seem not so bad. Chad promises that he won’t make her do anything she’s not comfortable with, & Gia Derza hesitantly agrees to try. Gia Derza awkwardly helps her older brother out of his pants & kneels in front of him beside the bed. She grabs at his dick & starts awkwardly & roughly rubbing it, & he remarks that she has to be gentler to start, with slow long strokes. She follows his advice & starts to improve her technique, & B4 long, Gia Derza is stroking her StepBrother’s cock like an expert, as he moans & says it feels really good. After awhile, he remarks that most girls will use their mouths to lube up a guy’s dick during a HJ, making it feel even more pleasurable. “I’m not sucking Ur dick!” Gia Derza complains. Chad says “That’s fine – Some guys R even happy with a girl just kissing the shaft a few times. That wouldn’t be so weird, right? They’ve kissed on the cheek B4, haven’t they?” Hesitantly, his teen StepSister says “Yeah”, she guesses so. Timidly, she brings her lips to the shaft of his dick & kisses. Chad moans loudly. Proud at seeing he likes her technique, Gia Derza continues, giving him sensual kisses up & down his shaft. Her StepBrother continues to moan, & puts his hand reassuringly on her head. This seems to encourage Gia Derza to be a bit bolder. She sticks her tongue out & starts licking up the side of his shaft. Ohhhh!, her StepBrother moans, surprised & turned on by the gesture. She does this a couple more times, & then even ends the final lick by going all the way to the tip & swirling her tongue across the tip. Her StepBrother moans uncontrollably, & gently pushes her head down so that her lips wrap around the tip of his cock. Her eyes widen in surprise but she doesn’t pull away, in fact she closes her eyes & goes down deeper onto his shaft with her mouth. But a BJ is just the start, because Gia Derza’s got lots more to learn. Lucky for her, her big StepBrother is ready to teach her!
