“This is perverted”, Lisa told herself as she crept down the darkened hallway of her house, moving closer to the soft moans coming from her parents bedroom.
It was almost one o’clock in the morning, and Lisa, clad in her flimsy powder blue nightie had been fighting the urge to peek for ages.
Thoughts of being caught flashed into her mind, the outrage of her parents, the embarrassment of it.
But other images flashed too. Images off passionate, wriggling bodies and glistening skin… a hard cock, swaying testicles… legs sensually spread wide and spasming.
Lisa couldn’t help herself, she had to look,Quietly, she opened her parents bedroom door.
In the darkness, Lisa crept silently forward, until she could see the bed, and the writhing bodies upon it.
The soft creak of the bed could be heard now, and in the dim light of the room she could see her father Homer, kneeling behind her mother Marge.
Homer had a handful of Marge’s hair, from behind, and his lower body was pressed firmly against hers. Marge’s head was arched back and her luscious ass was arched up against Homer.
The dimness of the light reduced the image to black and white, Marge’s ass looking smooth, round, and unblemished, and her father’s muscles rippling as he hunched into his writhing wife.
The covers were a heaped mess on the floor at the foot of the bed, and Lisa noticed that her mother was all but shredding the bottom sheet with her long fingernails which dug into the mattress deeply for support.
Lisa felt a knot in her stomach, one that twisted all the way down between her young legs.
Homer moved in slow, even strokes, arching his back and thrusting into Marge with long, deep jabs.
Each thrust brought a primal growl from deep inside Marge’s throat, and Lisa watched her mother’s hips move back instinctively, forcing Homer’s huge shaft deeper inside her.
“God! You’re so fuckin’ tight like this Marge!” Homer whispered, his words carrying, easily to Lisa’s ears in the nearby hallway.
Marge half moaned, half sighed her response, pushing her upper body up on her hands, her full breasts swaying beneath her slim, supple body.
“Fuck me hard Homer .” she breathed. “Fuck me hard and fast. Cum in me!” Lisa couldn’t believe her ears! Her nipples were already hard, excited by what she’d seen and heard so far.
Now they ached to be touched and Lisa’s right hand found her nipple, teasing it.
She watched as Homer began thrusting faster into Marge’s raised ass, their bodies making an audible “smack”,
Marge’s breasts bouncing, and the flesh of her ass rippling.
Lisa felt her panties clinging to her crotch, moistened with her own juices. “Yesss!” Marge hissed. “Fuck my ass. Pump your cum in my asshole, you big gorgeous stud.” Lisa heard the words and couldn’t believe it.
Homer her father was actually fucking her mother’s ass! She had heard about that kind of thing at school from sherri and terri, but treated it with incredulous suspicion.
Now she was witnessing it for herself, in her own house, with her own parents! It was incredibly exciting.
Lisa let out a low sigh… a sigh of lustful arousal.
Her left hand replaced her right on her nipples, and her right hand slid under her panties and between her legs.
Lisa knew she was wet, and she slipped one finger deep into herself, rubbing her clit frantically.
She had masturbated before and knew exactly how to bring herself off in the shortest possible time.
She slipped another finger into her tight, little cunthole and began to move it in and out.
The two bodies on the bed undulated and writhed about, glistening even in the semi-darkness of the room.
Marge’s long blue hair flailed about as her body heaved and bucked to Homer’s rhythm.
It wasn’t long before Homer groaned and began fucking Marge even harder.
He was pulling on her hips and slamming his cock into her so hard that Marge’s whole body shook.
To Lisa, it looked almost like Homer was trying to drive his balls inside Marge’s cunt.
Suddenly, they both stiffened and shuddered.
Their groans and loud breathing filled the air for a few long moments, and then they fell silent.
In the sudden silence Lisa stopped cold.
Her own heavy breathing was covered by theirs, as was the wet, squishing sounds her fingers had been making in her pussy.
She slowly caressed herself and watched the two lovers on the bed, her father on top of her mother from behind, both kissing and fondling each other.
Lisa finally realized the show was over and she crept back to her bed, still excited by what she’d witnessed.
Her own sleep came only after she’d rubbed her gooey little slit to orgasm, fantasizing about Homer’s cock as she came.
