As usual one summer night, I crept out of my bed and sneaked into the hallway, opened my parent's bedroom door slightly and with one hand in my panties the other in my sleeping bra cupping my right breast, I overheard them in their regular nightly fuck session talking about me. I opened their bedroom door more and I saw my mother Kathryn on top of my father slowly guiding his hairy shaft inside her shaven brown asshole. She grunted briefly then wiggled her ass cheeks to get the shaft deep into her, her large breasts swaying along with her wiggle.
My mother, Kathy, whom I find myself in constant competition for my father's attention, is also a large breasted, sexually open minded woman of 40 years with natural 36D breasts, pear shaped but with long, protruding brown nipples and flowing curly dark brown hair.
She then said: "Jules, you surely noticed how Nancy's tits have grown for the past six months?''
My father, Jules, is still in good shape and to my ultimate later pleasure and surprise has a very large, sweet tasting cock that emits a very strong male scent that I adore in a man.
I glanced at my dad, his face glowing with impending coital pleasure, he replied, "Huhhh. Yes I have love, I wonder if she's had them sucked on yet? I wonder if she's going to turn into a little cow slut like her mother?''
My mother then reached back and gave my dad a hard slap on his testicles, she replied: ''You pervert! I'm worried about her getting some sag lines on her breasts!''
I heard my father reply with a coy smile, "God she does have a nice set, I wouldn't mind giving her nipples a little tug, I bet she likes that. That would get rid of any sag lines!''
My mother moaned and started rubbing her clit, she opened her eyes, and I believe she saw me through the crack of their bedroom door. She said while panting and looking straight at my hand inside my panties, "Yesss, I believe the little cockteaser would enjoy a little pain, she always seemed too willing to receive a bare ass spanking when she was younger."
Jules, my father, pushed his cock deep into her ass so all I could see were his testicles dangling and said while gently thrusting inside her rectum, "Maybe we should start her on the same treatments you are on?"
My pussy was now moistening around my finger, I gently inserted a finger inside my lubricated opening and rubbed my small g-spot gently. Glancing back into the room, I noticed that my father had removed his penis from my mother's anus and was now rubbing it between her hanging pendulous breasts. I then noticed my dad grab his brownish stained cockhead and aimed it at my mom's tits, he released his cock head and sprayed her chest with his cum. She gently rubbed the white liquid onto her upturned mammary until her skin had completely absorbed my dad's cream.
She smiled at him and said, "Humm you smell so musky, maybe talking about Nancy helped you! Next time we'll have to fill a small container so that Nancy can rub it onto her breasts.''
In shock I quietly retreated to my room, my hand pinching my engorged pussy lips, preventing me from cumming. I was shocked and very excited at the fact that they were fantasizing about me and my sexuality. I was also slightly disgusted that they wanted me to put my dad's spunk on my tits. I untied my pink polka dot bra and stepped out of my pussy soiled panties so that I could look at myself in my closet door mirror.
I do pose a striking form of brazen sexuality, I am a 18 year old, buxom 36dd pear shaped breasts, dark red curly haired libertine woman. I recently started shaving my pussy lips, but I only lightly trim the pubes on top in a heart shape form. I looked at my breasts, they had ballooned in the recent months, I was very happy with them, they turned out to be porn star material. But after hearing my parents I was a bit worried about any sag lines and thought maybe I should try the treatments, I do want to keep my tits perky and full.
Turning around, I bent over and spread my ass cheeks with one hand, my asshole had curly dark hairs around it, and after seeing my mothers shaved anus I thought I should start shaving there too. I looked at my cheeks; they had grown considerably since my parents put me on the pill 6 months ago. I gently rubbed my puckered rosebud, enjoying the climatic tingling it brought to my nipples.
Standing back up, bringing my finger to my nose I inhaled my pungent rectum scent, I then sucked on my finger gently while saying, "Humm I think I need a wash. I smell pretty strong tonight.''
Hearing a noise behind me, startled, I turned around hiding my breasts with one arm and cupping my pussy with the other, I realized I hadn't completely closed my bedroom door when retreating from my spying adventure, the door was now completely open with my father standing there holding my discarded panties in his hand, staring at me with his mouth opened, his penis obviously tenting the pants of his pajamas.
I yelled, "Dad do you mind!!!''
He promptly retreated back into the hall while mumbling, "Sorry Nancy, just wanted to check if you were sleeping, thought I heard a noise. Ok goodnight."
Embarrassed and aroused I turned around to face the mirror only to notice my arm wasn't fully covering my breasts. In my haste and arousal I hadn't noticed that the whole time both my nipples were erected and pointing out, uncovered just above my arm. Upon realizing this uncontrollably I started furiously rubbing my clit and with a loud whimper came in a quick orgasm while crumbling to the floor exhausted.
I heard my dad's voice from the hall, "Nancy is everything ok?''
Gathering my shaking voice I replied, "Yes dad! Please just go away!''
Climbing back into bed, I just then realized he still had my wet smelly panties when he left my room. Feeling another tingling deep in my loins I squeezed both my legs together and climbed into bed thinking about my dad's pointing erection.
The next morning I got up late, wrapped a towel around my naked body, peeked into the hallway to see if the coast was clear and ran into the bathroom. I was a bit shocked to see my mother just stepping out of the shower. She didn't seem to mind and didn't even cover herself. She stepped aside to let me through, I closed the door behind me. I brushed her nipples with my towel when I passed her, I stared at them hardening almost immediately, she saw me staring and smiled and said:
"I saw you last night, I don't mind you spying on us fucking, I love having an audience, but be careful that your dad doesn't see you. He might get the wrong idea, your tits are already exciting him quite enough.''
Embarrassed I looked down, glancing at her shaven pussy, her outer lips swollen, slightly opened and hanging a bit down from her pussy. I quietly said, "I saw Dad covering your tits in sperm last night, you like that?''
