When their mother tells her they are trying to save some money to fix the attic so she can have her own room again she replies that there is no hurry, she will be fine where she is for a while. Her mother gives her a funny look and asks, “I thought you were just going to die if you didn’t get out of there, why the sudden change of heart?”
“I guess I’m just growing up and have to realize that I can’t have everything I want all the time. I know you and dad are trying as hard as you can mom.”
Her mother smiles and says, “Well thank you McKenzie I’m so tired of hearing you two bitch about it”.
Mac is crushed when she hears Austin say, “Oh yeah well I’m still not happy about it!”
The hurt he causes makes her lash out as she says, “Oh shut up Austin I don’t like being in there with you anymore than you like being with me.” She is hurt and mad at his seeming indifference to what she did for him after him not returning the favor in any way. He acts like he just slept through it she thinks. That thought makes her realize that maybe he did. Maybe he just thought it was a dream and because she had cleaned him with her mouth and tongue so well there was no evidence when he awoke. She doesn’t know whether to be happy or sad at this realization. It would explain his seeming indifference to her feeling closer to him as nothing would have changed in his mind.
How could he have hunched his thing in her mouth and moaned so loudly and cum with her sucking hard on his cock, squeezing his balls and not known it? It seemed incredible to her but it also made her smile knowing she had sucked her brother and his cock had influenced her orgasms and he didn’t even know it. Her mind filled with all sorts of nasty scenarios that involved her using his cock for fun and excitement as he slept, thinking it was Vicky, the girlfriend of hers he had moaned about last night.
She purposely waited until Austin had been in bed for over an hour before going up to bed herself. He was one of those people that went down with the setting Sun. He was always an early to bed and early to rise person while she was a nite owl preferring the night to the daytime. Especially if she could lay in her bed and play with her pussy till the Sun came up…lol…while texting with some boy she found hot.
She opened the door to their room and found him sound asleep on top of his covers as usual clad only in his jockey shorts. He lay facing her bed on his side and she could see the tip of his cock protruding at the edge at his thigh. It was hard to believe something so small could grow so large when he became excited. She had to stifle an urge to lay beside him and pull his underwear back and begin licking and sucking at his soft dick. Would he tell on her she wondered or lay there and enjoy it? If only she knew the answer her actions would be easy to decide. She sat on the edge of her bed pondering what to do as her clit began that now familiar pulsing as she remembered his taste once again. She loved the hot feel of his dick in her mouth, the texture of his swollen glans beneath her tongue as she laved at his Precum hungrily, sucking it from his hole as if it was an elixir of life.. These thoughts had her needing to touch herself but it was not quite dark yet and the room was still lit up by the Sun’s ebbing rays.
She scooted to the wall and leant back against it as she removed her shorts, and tonight, her blouse, leaving her sitting there in bra and panties. She decided to chuck the bra also and did. Her breasts felt supple beneath her fingertips and were firm with nipples that stood proudly erect. Rolling them with thumb and forefinger caused spikes of pleasure at her clit making her squeeze her thighs. Whenever the boys saw her breasts through a wet T-shirt they all said they’d like to suck and lick them. If she’s ever alone with one of them and they say that now she’s sure she will take him up on it if it would just be his word against hers if he told someone. She thought of Austin sucking her nipples as he touched her pussy and instantly became wet. She was nervous and her emotions were agitated at knowing how badly she wanted to suck his cock again. She couldn’t help herself as her hand slid in the leg of her panties and her fingertip began rolling her now taut bud. As she rolled it beneath her fingertips, thoughts and ideas that moments before she had dismissed as impossible to accomplish, became completely plausible in her now aroused state.
Where five minutes ago she had told herself if he awoke to her sucking his cock he’d tell her parents, NOW, he would probably lay there and allow her to make him cum. The more her hips hunched, fingers excitedly agitating her clit the easier it seemed to just take his dick in her mouth and suck it without consequences. Soon she lay back moaning as her fingers entered her pussy, pressing into the wet hole of her sex, eyes closed as she relived the previous nights experience.
Austin was awakened by something and as he lay there listening he heard a moaning sound. It seemed to come from Mac’s side of the room and when he opened his eyes he saw her. His first instinct was to ask her what she thought she was doing. But something about the look on her face as her hand moved, digging at her pussy kept him quiet. His eyes fell to her chest and he saw her bare tits and his dick jerked, began swelling as his heart began to pound in his chest. His sister was leaning back against the wall with her thighs spread open widly hand in her panties playing with her pussy. He’d never seen a girl, any girl touching herself. Seeing Mac so obviously enjoying it had his dick pulsing, stiffening.. He lay and wondered what had gotten Mac so excited that she would do that with him right beside her. She was his sister and he knew he shouldn’t be watching her. Knew it was as wrong for him to watch as it was for her to be doing it in front of him. But he couldn’t take his eyes from her as her hips moved, hunching as passionate moans erupted from her lips. She appeared and sounded like she loved what she was doing but there was desperation in her sounds. She sounded like she felt like he did right before he cum while beating off.
He didn’t even know Mac had feelings like those or that she knew anything about sex. Everyone thought she was even dumber about sex than he was. He knew she had lost her hymen in a bike accident that jammed a narrow seat into her pussy extremely hard a year or so ago. But seeing her like this, doing the things he imagined Vicky doing as he stroked his hard dick was kinda exciting him. He knew it felt good when he beat off and sometimes when she spent the night with friends he would spend some time thinking about doing things to Vicky a girlfriend of Mac’s that always made him hard to think about. Maybe she was just doing what he liked to do. He felt his dick stiffening, poking from his underwear as the air felt cool upon his inflamed glans. He knew she could see it if she opened her eyes just as he was seeing her. He closed his own eyes and tried to will his dick to stay soft but the hunger in her slight moans had him jerking, growing longer and thicker with each desperate sound from her lips. He tried to muster the courage to roll over but the sight of her groping her pussy had him mesmerized. He had never seen a girl cum and didn’t want to miss it if she did, even if it was his sister.
