Susan catches Brett having sex with his sister, Erin. Instead of stopping them and instead of telling their parents, she wants to watch them having sex.
Eager to have sex with his sister, at his sister's request, Brett walked out of Erin's room to get the measuring cup in the kitchen downstairs. Weird that she'd want to measure his cum in the way that his mother does with his father, he wasn't about to question or object to his sister measuring his cum. So long as he'd get to have sex with his sexy sister, he didn't care what fetish or what kind of kink aroused her or that she needed to do for him to have his wicked way with her hot, naked body.
Thinking that they were alone in the house, Brett emerged from Erin's room without his pants and underwear. He had an erection and a sense of freedom overwhelmed him as soon as he neared Susan's closed bedroom door. As if to pay homage to her, he stopped in front of her room and stared at her closed door as if she was standing there and he was staring at her.
He wished she was home to open her bedroom door and catch him naked in the hall. Being that his sister made him so horny, he had the urge to go in Susan's bedroom and go through her panty drawer. If he wasn't about to have sex with his sister, since he's done that before, he would have done fished through her sexy lingerie. If he wasn't about to have sex with his sister, he'd make himself comfortable on Susan's bed while masturbating and holding a pair of her panties in his hand before sniffing them. If he wasn't about to have sex with his sister, he'd spend some quality time in Susan's room and going through and touching her things, especially her sexy underthings.
Only, as if a dream come true or a sexual fantasy, as soon as he was about to move on from Susan's door to go down to the kitchen for the measuring cup, Susan emerged from her bedroom wearing her sexy, standardized uniform of a short skirt and a low cut top. He didn't know she was home. He couldn't believe she was here. He couldn't believe she was standing there staring at him in the way that he was standing there staring at her.
Always dressed in a short skirt and a low cut top, she never wore anything that didn't show her long shapely legs, not even a tight pair of jeans that shaped her sexy ass. He's seen her in a pair of tight, painted on jeans once and she looked incredible. Never wearing a bulky sweatshirt that hid her big breasts or a tight sweater that highlighted her tits, she never wore a top that didn't show her long line of cleavage, the tops of her jiggling breasts, and the impressions of her big nipples.
If judging her by how she dressed every day, short skirts and low cut tops, one may think that she was a whore, but she wasn't. Slutty perhaps, sexy definitely, he could tell that she was proud of her long, shapely legs, and big breasts. Not shy or embarrassed to admit, more than once he's dreamt about her long legs wrapped around his waist and/or his neck. More than once he's dreamt of her on top of him bouncing topless and her hanging her big tits over his face for him to suck her nipples, while she pounded his prick deeper in her pussy.
As soon as he turned away from her room, the sound of her doorknob made him look back. Hearing her doorknob turn, he froze. As if injected with a paralyzing drug, unable to move, all he could do was stare at her bedroom door. As if happening in slow motion and as if he was dreaming the scene, he watched her doorknob turn and her door slowly open. Knowing full well who was behind the door, his eyes were transfixed on her sexy image.
Forgetting for a second that he was so exposed and so sexually excited, it was then that he realized his semi-erect cock was in plain view. Unable to run away, he could only stare at Susan standing in her bedroom doorway staring at his cock in the way that he was staring at her blouse and bra clad breasts. As if hypnotized by her beautiful breasts, he loved the heavy impression her breasts made in her clothes and he'd give anything to see her huge tits and to suck on her big nipples.
She was so beautiful. She was so sexy. She was his mother's age and a real MILF. In the way that he's always wanted to have sex with his mother, from the very first time he saw his mother's best friend so long ago with her blonde hair and bodacious body, he's always wanted to have sex with Susan.
His wildest sexual fantasy was to have sex not only with his mother but also with his mother's best friend at the same time. How hot would that be to watch them taking turns sucking his cock before he pounded his mother's pussy while eating Susan. Switching off, he imagined pounding Susan's pussy while he ate his mother. Knowing it was nothing more than a sexual fantasy, here he was now standing in the hall with Susan staring at his throbbing prick. As if they were coworkers passing in the hall, he only wished that this was a daily occurrence.
"Brett," she said with a laugh.
"Susan," was all that he could say.
She stared down at his exposed prick before saying another word. There was a silent pause as if her pause was out of respect at how large his appendage that protruded from his shirttails was. Tit for cock, she stared at his erection in the way that he always stared at her blouse and bra clad breasts and in the way that he was staring at her now. He loved her tits. She had such big tits and as big as his mother's tits and he wished he could touch them, feel them, fondle them, caress them, and suck them. He do anything to pull, turn, and twist her nipples while biting her big nipples.
"How nice to see you, all of you," she laughed while using what she had just said to ogle his cock longer.
"Sorry," he said.
