Now it was his turn. He undid her jeans and stripped them off, revealing red satin panties and tufts of pubic hair peeking out the top and sides around her legs. Licking his way down her chest he finally positioned his face in front of her panties, obviously delighting in the aroma. He put his mouth over her mound, still through her panties, while still running his hands all over her body, up and down her legs, pinching and fondling her nipples and breasts. Her head rocked back as she visibly enjoyed this very much. Finally he stripped her panties off and dove into her pussy, lifting her left leg on to his shoulder for better access. After about a minute of this he got up and they laid across the bed, and he went down on her a little while longer.
After a while she pulled him up and he slowly eased his cock into her. He left his cock in her for a bit for her to adjust then picked up a pretty good pace, slowly increasing in speed, occasionally pulling his cock all the way out to tease her. Next he took his cock out, rubbed it along the length of her pussy a few times then shoved it into her waiting cunt. She let out a low grunt that was fairly audible and he really started going at her, really fucking her hard. She began to moan, clutching at his back, her legs high in the air as he kept up his pace. The bedsprings were squealing and barely covered up her moans; he was really giving it to her. She let out an "oh" and was clearly cumming on his big cock.
When she finished, he pulled out of her and proceeded to go down on her again. She wrapped her legs around his head as he also played with his cock a bit to keep himself hard. They spoke a bit (I couldn't quite hear) and she turned and got on her knees, her tits resting on the bed. He positioned himself behind and drove his cock back in her pussy hard, forcing her face into a pillow. I came all over myself at the sight, yet I was so turned on I continued jacking off. The pillow muffled her grunts as he continued to stuff her pussy with his massive cock. He reached around to fondle her breasts, sliding his prick deep inside her, then pulled out once more before slamming his cock into her, cumming deep into her pussy and lowly moaning while kneading her breasts.
He backed away from her and she leaned forward, letting his already shrinking cock flop out of her stretched pussy. She turned and began to clean his cock off. I couldn't believe what a whore my mother really was, how much she noticeably loved his cock and cum. When she was finished she got up, put her red panties back on they went to bed, kissing before turning out the light.
I stared off into space, still jerking off my erect cock. I had cum all over myself, but I didn't care. I was thinking what a wonderful discovery this was. Eventually regaining my senses I fished a poster out of a nearby box and taped it up over the hole, so that no light would escape from my room into theirs (even though their room faced east [it was a lot brighter]).
A few days later while everyone was unpacking downstairs I snuck their room and found the red panties in a heap of dirty clothes on the floor. I stuffed them into my pocket and locked myself in my room. My hands were shaking as I pulled them out of my pocket, dropping my shorts to the floor and pulling out my cock. I could already smell the pungent aroma from them as I brought them to my face. They were stained with the mixed cum of my mother and father, and I brought my self to another orgasm, smelling their sex that I had witnessed.
I knew I would enjoy the experiences I would have in this new house.
