My grandpa promised to take me into the city by bus to visit a couple of museums, my grandpa was waiting for me downstairs in the kitchen. While I was in my bedroom putting my short white cocktail dress and my ultra sheer black pantyhose on along with my black patent leather 4-inch stiletto high heels, I applied my glossy red lip gloss and a spray of my French perfume and off I went downstairs to greet my grandpa.

We didn’t have to wait that long until the bus arrived, it was really crowded with tourists since it’s Saturday. My grandpa managed to get a seat at the back of the bus, and I tried to follow him but there were so many people that it was difficult for me to get through. With more people getting on I moved further back until I was standing in my 4-inch black stilettos right in front of my sitting grandpa as I’m struggling to hold onto the overhead safety strap.

Suddenly the bus lurched forward, and I stumbled in my heels and lost my balance and fell backwards in my grandpa’s lap with my back towards him, as he wrapped both of his strong arms around my waist. I felt really awkward because we don’t have that type of touchy feely relationship, so sitting on grandpa’s lap like he’s Santa isn’t something I normally do. I tried to get up but there was to many people that I couldn’t get any leverage with my high heels as I heard my grandpa behind me saying, ”It’s okay princess !!! You can stay sitting on grandpa’s lap”!!!! He whispered in my ear.

After about 5 minutes sitting on grandpa’s lap and with the bus hitting potholes and I’m bouncing up and down on grandpa’s lap I suddenly felt something hard brush up against the underside of my ultra sheer black nylon encased thigh, it was very close to my pantyhose covered virgin pussy. I thought I was imagining things at first but then I felt it again. Then to my shock and horror I realized that the only thing that it could be was my grandpa’s cock.

As the bus continued on swaying and bumping down the road the rubbing pressure of his cock on the underside of my nylon covered thigh increased and I could feel my grandpa’ trying to move backwards into his seat. I didn’t know what to do so I remained as still as possible and pretended I didn’t notice anything was wrong, but I was highly concerned that my short white cocktail dress wasn’t covering my freshly shaven virgin pussy underneath me as it rode up a little underneath me when I fell into grandpa’s lap.

There was only the ultra-sheer black nylon fabric of my pantyhose, and the thin material of my granddad’s polyester pants was between my tender pink virgin clitoris and his big old cock, The bus suddenly lurched to one side as it took a corner too fast and I was jolted up and down on my grandpa’s lap and with the jolting movement my petite body grinded down hard on his lap causing his hard cockhead to push tightly up against my ultra black sheer pantyhose covered pussy lips, as I gasped out, ”Ohh my God !!!! Noo”!!!!!
I was now in complete panic because my young pussy was now completely exposed as the head of my grandpa’s cock was pushing in between my protected ultra sheer nylon pantyhose covered pussy lips.

It felt really big and thick about 8-inches and really thick unlike my boyfriend’s 5-inch cock who I’m going to marry after I graduate high school this year, I just turned 17 last week and I haven’t lost my virginity to my boyfriend/ husband yet, I want to save it for him on our wedding night but I do suck his dick and give him hand-jobs.

I felt so embarrassed as I felt my pussy getting extremely wet and aroused as I heard my granddaddy’s voice whispering in my ear, ”Please can you get up Britney”!!! I tried but there was no place for me to go. He remained tense and I wondered what must be going through his mind having me sitting on his lap all dolled up and whether our relationship would be strained from this most embarrassing nightmare.

I glanced at my watch, and we only had another 30 minutes to go, and a few minutes later the bus hit a deep pothole and I was jolted up back into my grandpa’s lap and to my horror my granddaddy’s big hard 8-inch dick easily popped through and penetrated right through my ultra sheer black pantyhose and as I sunk down on his huge dick while my tight wet pussy lips parted and stretched out as his dick ripped through and popped my hymen cherry.

I quickly covered my mouth with my the palm of my hand and squealed and groaned, ”Mmmmmmph !!!!!!
Mmmmmmmmmmmmmmmmmmmmmphh !!!!!! Mmmmmmmmmmmmmmmmmmmmmmmpph”!!!!!!!
From behind me I heard a suppressed grunt and then nothing, my granddad’s cock was now fully buried up inside my young 17-year-old pussy now as each speed bump came and went, we were thrown back together with my grandpa’s big cock deeply buried inside my warm silky wet pussy and it’s stretching out my smooth inner pussy walls as the two of us quietly gasped and grunted.

I can now feel a slow tingling feeling coming over my body and I desperately tried to hold off the inevitable, I mean what type of granddaughter orgasms on their granddaddy’s cock. It was no good as the speed bumps and vibrations caused his dick to be constantly forced back inside me.

I lost it as I felt my nylon encased toes curl inside my 4-inch stiletto heels as I covered my mouth with my left hand and with my right hand, I dug my long sharp fingernails into my grandpa’s thigh as I dropped my head so no one will see or hear the ecstasy on my face as my body shook while my pussy tightly squeezed all around my granddaddy’s big dick, then I felt fireworks going off through me as my pussy orgasmed and spasmed.

I quickly felt my pussy being stretched further apart while my grandpa’s throbbing and pulsating cock suddenly swell up as I heard him grunt in my ear, ” No !! No !!!Please God !!! Don’t let me cum in my granddaughter !!! Arrrrrrhhhhhhhhhhh !!!!! Fuck !!!!!!! I’m so sorry Britney”!!!!!!!
That’s when I felt a sudden hot pumping gush of granddaddy’s sperm being pumped up deep inside my fertile womb while my spasming pink pussy was milking every last drop of creamy white sperm from his thick fuck muscle.

We both froze trying not to attract anyone on the bus to watch grandpa fucking me on his lap. We were breathing heavy and panting while trying to regain our composers, and I was so mortified and embarrassed. My grandpa’s dick was softening up but it was still stuffed up deep inside me.

As he held me by my waist, I squirmed and wiggled a little and then I felt his cock plop right out of my cum filled pussy, as my grandpa’s sperm mixed with my kitten cream and my popped cherry hymen blood slowly leaked down inside my torn ultra sheer black pantyhose and down on his lap.

The bus finally stopped and I struggled up on my black 4-inch stiletto heels and I quickly pulled my white cocktail dress down and stood there standing up in my 4-innch stilettos and I slowly turned around and looked my granddaddy in the eye as cum mixed with my blood is dripping on the floor of the bus and slapped him across his face and yelled. ”HOW COULD YOU GRANDPA”!!!!!!!!!!!
Three weeks later I found out that I’m pregnant with my granddad’s baby and my boyfriend/future husband broke up with me after I told him that. (THE END) This story is dedicated to all of the perverted old granddads who love fucking and raping their own young virgin granddaughters.
