*
Erin and Brett sitting in a tree, brother and sister naked while kissing, k-i-s-s-i-n-g.
Brett, can I talk to you?" Erin called out to her brother when he walked by her room.
As if he was expecting her to be standing there in her bra and panty, topless, or naked, hoping to see something he shouldn't see of his big sister, he always looked in her room when walking by her room.
"Sure what's up?"
"I just want to talk," she said.
Usually wrong when reading someone's face, oblivious to the clues of body language, he misread his sister's facial expression now. Instead of seeing the sexual excitement on her face, he misread that as anger. A total bitch, she was always annoyed with him for some reason or another. What he mistook for annoyance was really sexual interest. A brother who wants his sister, especially at that age, is common but a sister who wants her brother, especially at that age is rare.
"Oh, oh," he said by the look on her face. He erected his 6'3" frame as if about to through a winning touchdown football pass down the field. "This sounds serious. What did I do now?"
Always something, figuring she was mad, especially when he laughed and she didn't return his laugh, he entered her room with trepidation. With her always being moody and bitchy, he treated his sister with kid gloves. She soothe his uneasiness when she gave him something to see. She flashed her bright white panty, when she moved her legs closer together, she was sitting on her bed when he entered her room and he wondered if her up skirt flash was deliberate of accidental.
Dressed in a short skirt, she displayed a triangular patch of her white panties over her shapely thighs even with her knees glued tightly together. Wishing she would, on the pretense that she wasn't aware that he could see and was looking, he'd give anything for her to spread her legs a little more to give him a better view of her panties. Wearing a low cut, button blouse that showed her abundant cleavage and more whenever she leaned forward or when he was standing over her, in the way he was now, he'd give anything to touch and feel his sister through her clothes while undressing her. He'd so love to stick his horny hand down his sister's blouse to feel her big breasts while fingering her nipples. Like mother like daughter, in the way that his mother was so very pretty and so very sexy, his sister was also so very pretty and so very sexy too.
"Close the door," she said. "I don't want anyone to hear."
Close the door? She shocked him when he asked her to close her bedroom door with him in it. Normally, always kicking him out of her room, she asked him to close her bedroom door behind him whenever he was leaving her room. Submissive to her, he always obeyed her but enjoyed teasing her at the same time.
"There's no one home," he said with a shrug while listening at her bedroom door and looking down the hall. "We're alone," he said closing the door to his sister's bedroom anyway.
With her bedroom door closed, transported to another place and time within a combination of flowery scents, he could smell her perfumes that she never left the house without wearing. As if he was in an upscale boutique instead of in his sister's bedroom, everything, her clothes, her knickknacks, her makeup, and hair accessories, even her stuffed animals and dolls, were all so neatly organized and displayed. Tossing his clothes on the chair or on the floor, before ending up beneath his bed, his room was a total mess. If it wasn't for his mother always cleaning his room, no doubt, he'd have bugs in his room. Weirdly enough in difference to his room, wishing his room was so neatly clean, he liked how neatly organized his sister's room was.
A first time for everything, in all the years they've lived together, he's never been in her bedroom alone with her and with her door closed. Immediately he felt as if he was doing something naughty or was about to do something wrong. Seeing her panties made him horny for his sister. Actually he didn't need to see her panties to be horny for his sister, he was always horny for his sister.
His way to get a prolonged look at her panties, he suddenly wanted to tickle his sister. Imagining her falling back on her bed with her legs spread wide open, he imagined cupping his sister's pussy through her panties while she beat the shit out of him. Maybe while she punched him, kicked him, and pinched him, he even get a groping feel of her big breasts. Certainly, it would be well worth a beating to hold his sister's cunt in the palm of his hand, even if it was only through her panties. As if an epiphany with a modicum of insight, now he knows why his sister never invites him in her room, especially with her door closed.
"I saw you last night," said Erin to her little brother while staring up at his face with her big blue eyes before looking down at the bulge he was unable to conceal in his pants.
"So? I saw you last night too," he said with a laugh. "We live here. We see one another every day. Duh?"
"What I meant to say was," she said returning his laugh while looking up at his face, no doubt, to watch his reaction to what she was about to say. "I saw you masturbating last night."
"Masturbating? Me masturbate?" With eyebrows raised with his palms facing up, he looked as if he was a petty thief accused of shoplifting. "You're mistaken. You did not see me masturbating," he said falling back on his heels instead of being his confidently annoying self.
"Don't even bother trying to deny it. I saw you masturbating Brett."
"I don't masturbate Erin. Never have and never will," he said defensively. Embarrassed as well as sexually excited that his sister not only knows that he masturbates but also caught him masturbating, he wondered where his sister saw him masturbating.
Suddenly as if he had put his finger in an electrical outlet and received a shock, he was sexually aroused. Wow! Erin saw him stroking his cock. Not embarrassed that she saw him masturbating, he more wondered what she thought about seeing his big prick before turning his thoughts to how, when, and where she caught him masturbating.
Thinking about where he was last night that he was masturbating and that she could see him playing with himself, as he was always masturbating, he remembered that perhaps she saw him hiding behind the tree in the backyard while watching his mother undress. Nah, he would have seen her if she was out back in the backyard. She must be referring to another time. Maybe she saw him masturbating when he left his bedroom door open for Susan to see him masturbating. Reciprocating her exhibitionism with his, whenever he's alone in the house with her, she undresses with her bedroom door open enough for him to see her in her bra and panty, topless, and/or naked. It's only fair that he should show her his cock too.
"Bullshit," she said with a laugh. "You're always masturbating."
"Being that I'm the star quarterback Erin on my high school football team," he said puffing out his chest, "my last year as a senior on the team, I need to conserve my energy. I don't waste my energy by masturbating during the football season," he said with assertiveness. "I do all my masturbating after the Super Bowl," he said laughing.
"Ha! You're a virtual masturbation machine," she said pretending she had a cock and was masturbating herself. "You're always masturbating. You make the whole second floor shake when you're pulling your prick," she laughed. "I can only imagine how much cum you've wasted jerking yourself off while thinking of God knows what," she said becoming flushed.
No doubt and according to the entries she made in her diary about her brother masturbating so much, she wondered how much cum he wasted. If there was such a way, she wished she could measure his cum to extrapolate her answer as to how much he cummed in a day, a week, a month, and a year. Being the cum slut that she is, she's written in her diary more than once that she'd love to measure her brother's cum in the hopes of getting him to cum even more in the way that her mother inspires her father to cum more.
"In your dreams Erin. I don't masturbate," he said denying his fondness of masturbation.
"Maybe you masturbate over Mom stripping herself naked or maybe you masturbate over me," she said ignoring his denial with speculation of her own.
"Mom naked? What are you talking about Erin? I don't masturbate and I don't masturbate while thinking about Mom naked. Gross," he said suddenly looking embarrassed as if she had caught him in a lie and she had.
"Maybe you masturbate over me, your own sister," she said again, while watching him squirm, as if wanting him to admit that he masturbated over her.
"You're the one who masturbates," he said pointing the finger of accusation at her to put her on the defensive.
"How do you know that I masturbate? Were you spying on me? Do you have a camera hidden somewhere in my room," she said looking around her room. "Are you watching me Brett dressing and undressing? Do you get off watching your big sister stripping naked? Eww. That's so gross," she said. "God you're such a pervert, an incestuous pervert, that's what you are."
"I don't have to spy on you to know that you masturbate Erin. I've heard you in the bathroom when you're in the tub. I heard you rubbing your legs together in your room as if you're a cricket," he said laughing. "You're not very quiet when having an orgasm," he laughed. "You thought you were home alone but, one day last week, when I came home early and you were taking a bath, I heard you masturbating," he said.
"Liar! You did not," she said unable to control her face from reddening obviously by the thoughts of your brother hearing her having an orgasm.
"When I heard you screaming, I thought there was something wrong. Then I heard your vibrator," he said laughing. "On the pretense of saving you from an intruder or a rapist, it took all the self-control that I had not to barge in on you while pretending that I didn't know you were taking a bath," he said with a laugh.
"Yeah, well, pervert, I saw you outside behind the big oak tree watching Mom strip naked," she said. "I saw you jerking off to Mom removing her clothes. You're such a pervert Brett to masturbate over Mom while watching her undress. What's wrong with you? That's so wrong," she said shaking her head. "That's just so nasty."
"I was not masturbating over Mom undressing. I didn't leave my room all night last night," he said lying. "Besides, I'd never watch Mom undressing. That's incest," he said. "I'd never do anything like that, watching my own mother undress, while masturbating. You must really have a low opinion of me to say that I masturbate over Mom."
"Liar. In the way that you leer at her and undress her with your eyes as if she's standing there naked, keep telling yourself that you're not sexually attracted to Mom. Liar. You're such a liar," she said. "I bet if I undressed right here and right now, you'd watch me. I bet if I stripped naked right here and right now, you'd pull out your cock and masturbate to my little, impromptu striptease show."
"I'm not a liar," he said gulping while imagining his big sister stripping off her clothes. Just by the horny thoughts of Erin standing before him naked, naked, naked, naked, he couldn't wait to return to his room to masturbate. "And if you started stripping off your clothes, I'd leave your room and close your door behind me," he said lying again.
If only she knew that the thoughts of his sexy sister stripping off her clothes and standing naked in front of him made him dizzy with incestuous, sexual excitement and lustful desire for her. He wondered what he'd do if she was teasing him by slowly stripping off her clothes before standing there naked. No doubt, if she stripped off her clothes in front of him, he'd pull out his cock before forcing her to her knees to suck him. If she was standing there naked, he'd push her back on the bed to fuck her.
Oh yeah, definitely, he had no compunction stopping him from having sex with his sexy sister. For her to even suggest stripping naked, obviously she wanted him as much as he wanted her. Only, his bitch of a sister would never strip naked. She has an entire college dorm of boyfriends to entertain them with her beautiful body, her experienced hands, her hungry mouth, and her always wet pussy. Why would she strip naked for him when she has all of those others to sexually tease?
