...ght 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.
