Work Text:
A long day was ahead of them. Grandpa Victor was moving into his new house and needed his things picked up from the old place. He had some stuff he would not trust with the delivery firm, and wanted it taken in the car.
His son, Mark, came over, bringing his lovely, 16 year old daughter Tina with him. She was a very pretty girl, with brown eyes and long blonde hair. She always liked visiting her grandparents as a kid. The news that grandpa Victor was moving to a house close to them made her happy. He must have been lonely these past few years since grandma's early death, she thought. When her father asked her if she wanted to come along for the trip she happily agreed, even though it was a three hours drive one way. She wanted to see the old grandparents' house one last time.
Although they were father and son, Victor and Mark were not much alike in appearance. Mike was physically barely average, while his father was always the manly type, and was strong as an ox even now at 60. They also had completely different personalities. Mark was a social type, while grandpa Victor was quite formal and could be strict. Tina was always the only exception to that. He always seemed to be in a good mood when his favorite granddaughter came to visit.
Mike's first thought when they arrived was that there was not much to be moved. He was wrong. He did a lot of pacing up and down and muttering under his breath. "No way. It's not going to fit in." Eventually he calmed down. After staring at all the boxes for several minutes he said "I have a plan."
He quickly explained it. The car would be fully packed except for the driver's seat and one of the rear ones. Tina would have to share a seat with grandpa. She wasn't sure how she felt about that. It was a three hours drive back, in the best case scenario, sitting in someone's lap for that long won't be comfortable for either of them. Grandpa Victor just watched, and Tina had a feeling he was kind of amused by the whole situation.
It took them more than an hour to get everything in the car. There was a mixture of boxes, bags and loose items. Every tiny space was now crammed with something. Mike just hoped they didn't get stopped by the police for being overloaded. He did a final check of the house just in case they had missed anything. Nothing, so they were all packed. "Time to go.", He said.
Mike and his daughter Tina waited by the car while Victor was having a last look at the house. Tina got a little sad as she watched her grandfather looking at the house. He had shared it with grandma for nearly thirty five years.
Tina was always flattered to hear grandpa Victor say that she looked just like her grandma in her youth. She always thought grandma was a beautiful and elegant lady.
Finally, they were ready to go. Victor sat in the back seat, Tina eased herself on his lap and when she found a good position her father closed the door. It was a tight fit but not as bad as she thought it would be. Without checking if they were OK Mike got behind the wheel they were driving off. He put the radio on which was hard to hear in the back because of all the stuff in the car. Tina had to shout to ask him to turn it up.
Everything was fine for the first twenty minutes or so until they hit a bumpy road. Not too bad but enough to make Tina bounce a little. She started feeling something poking her butt a slightly with every bump and couldn't figure out what it was. Her first thought was that her grandpa had his phone or keys in his pocket, but the position didn't seem right.
Then a thought hit her. "Could it be?!" She thought, immediately starting to feel tingles all over her body and her cheeks were turning burning red. She closed her eyes and started to think un-sexy thoughts. It wasn't working, she was getting excited as she felt the thing in her grandfather's pants growing and getting harder.
Victor suddenly spoke. "I'm sorry, honey, I hope you're not too uncomfortable. It'll go away in a minute."
"Oh, it's fine." Tina replied, blushing.
The road got a bit smoother but Victor's cock stayed hard. She did her best to ignore it. However, after another twenty minutes she felt it throbbing, poking her harder. It felt really big and a little uncomfortable. She moved her bottom slightly until it was positioned nicely on his cock.
Her head was spinning. "The best thing to do is ignore it. Pretend it is not happening." She told herself. That is what she did until they hit a big bump and she jumped a little, her skirt lifted and she landed back on grandpa's lap with her pussy pressed directly on the large, hard rod in his pants.
Something came over her, some kind of a primal instinct, and she continued moving her hips ever so slightly, grinding her panties on the large, hard rod in grandpa's pants. She was sure she was being subtle about it and she used the opportunity with every bump to grind a little harder. She shivered a little when she felt pressure on her clit.
"Bumpy road." Grandpa said and Tina jumped a little again, but this time because she was startled by him suddenly speaking.
She blushed more and laughed nervously. "Yeah. I hope I'm not too heavy."
"You're light as a feather, sweety."
It was a nice, sunny day and Tina was wearing a short, plaid skirt and a tight shirt. She was athletic, but had very feminine features. Her butt was a perfect, round shape and her beautifully tanned skin drew the eyes to her soft thighs. She was also blessed with a pair of developing B cups which were growing fuller and rounder each day.
She was well aware that what she was doing was pretty wild, especially with her father right there in the front seat. He was focused on driving and listening to the song on the radio, and he couldn't see them anyway since they were sitting behind him and all the stuff they crammed into the car blocked his rearview mirror view.
In her head it was all still pretty innocent. Teasing her grandpa subtly was just a fun way to make this drive go by quicker.
"Are you two OK in the back? The ride is not too hard for you?" The voice from the driver seat surprised Tina.
Grandpa laughed before replying. "It's hard, but we're okay." Tina was surprised by how bold her grandpa was with that reply. He was a lot of things, but playful was not what most people would describe him as. But, as usual, he was in a great mood when she was around.
That is when she felt grandpa's hands on her hips and he started to move her bottom on his lap. She hesitated for a minute, but then went along with it and started to rock back and forth on him.
"It might go away faster this way." He said.
Then one of his hands left her hip and went to her thigh. Grinding her butt back and forth made her skirt lift up all the way to her hips and her panties were completely exposed. After a few minutes of Victor's big hand sliding to her inner thigh and getting dangerously close to touching her panties, Tina slowly opened her legs a bit more. Her head was spinning. She wanted to be touched more.
Mike kept driving and listening to the radio, oblivious of what was going on behind him between his daughter and her grandfather. Victor's fingers went to the bulge of her pussy and she winced a little. When she didn't protest he started making circles with his fingers, pressing slightly where her clit was.
Tina was extremely excited, but she knew she had to stop this. She was just teasing, like she does with her teachers at school. She discovered a long time ago how fun it was to tease older men who couldn't help but steal glances at her thighs when she let her skirt pull up as she sat down. And now that her breasts started to grow rapidly she loved wearing tight tops and she was well aware that she was getting a lot of looks. Even her father couldn't help himself and would sneak a peek when he thought she wouldn't notice. She didn't mind and loved the attention.
She didn't want to be rude to her grandpa and wanted to tactfully remove his hand. Just as she was about to change the position and turn her legs to the side, grandpa Victor's fingers pulled her panties to the side. A second later one of his large fingers was pushing at the entrance of her smooth, wet pussy.
"Do you want to stop for a break?" Mike asked and Tina almost screamed from surprise, both at her crotch and her dad's question.
"No, I think we should keep going." Victor replied and started moving his finger in and out of his teenage granddaughter.
Tina was too stunned to say anything. The only time someone touched her pussy was when she lost her virginity with a classmate half a year ago. It was a very awkward experience. The boy had no idea what he was doing, but he had a pretty big penis, Tina thought. She thought it would be painful, but she loved it when he entered, even though he was very clumsy about it. She was just getting into it when he came after only a minute of fucking her. They barely spoke a word after that. But that day she realized that she would love sex.
"This is crazy. How do I stop this?!" She thought and realized she was rocking her hips back and forth slightly, encouraging that finger to enter her.
Slowly at first but then faster and she started to softly moan.
"You sure you're okay?" Mike asked again. The radio and the traffic muffled the sounds from the back almost completely, but he thought he heard Tina's voice for a second.
"Yeah, we're fine. Tina has a small cramp, but I'll rub it out." Victor said and started playing with her clit.
"Really? Is rubbing it really gonna do it?" Mike asked.
Victor continued working on Tina's pussy while she tried to compose herself before replying. "Yes, grandpa Victor is an expert. He knows exactly where to put his fingers."
"Okay then, let's keep going." Mike said.
"Yeah, let's keep going". Victor agreed as his hand worked skilfully between the young girl's thighs.
"Put your hands on the boxes at the back and raise yourself." Victor instructed and Tina did as she was told, lifting her butt up from her grandfather's lap. She figured he was in an uncomfortable position and wanted to adjust better, but then she heard the zipper on his pants.
He unbuttoned his pants and released his cock. Before she even realized what was happening he already pulled her panties down. She was in an awkward position so she couldn't take them off completely. She sat down on his lap, feeling his fat cock touching her ass cheek and she pulled them off by herself, lifting her butt slightly and sliding her panties all the way down her legs. Victor asked her to hand them to him.
He grabbed her by the hips and made her lift her ass high and she knew what his plan was. She was extremely unsure about this. His cock seemed so thick that she didn't believe she'd even be able to take the tip inside.
As she was trying to balance herself with her ass in the air and her mind was running wild thinking how crazy all of this is, her foot slipped and she kicked one of the boxes.
"Hey what's going on back there?" Mike yelled.
Tina pulled her leg back and then raised herself up again. "Sorry, I was trying to get a better position." She said quickly.
Grandpa's cock was now pressing against her opening. She felt her foot start to slip again and to prevent herself from kicking the same box again there was no other choice than to let herself sit back down, on a fat, rock hard cock.
She let out a loud, long moan as the big, thick tip penetrated her drenched young cunt and started squeezing deeper inside of her.
"Did you manage to get in position? Be careful. I need to concentrate on driving." Mike shouted.
"There is a place to stop in about a mile or we can continue for another half hour." He added.
"Keep going!!" She quickly shouted back.
"Yeah, we just got ourselves comfortable. We need to enjoy it before we stop." Victor said and Tina heard the amusement in his voice.
"Fine, but we're stopping at the next exit. I need a break." Mike said.
Tina placed her hands on her grandfather's legs for support and started to bounce up and down slowly and carefully. She felt the old, big cock penetrating her deeper every time she lowered herself back down. She couldn't control her moans and was grateful that a loud song was playing on the radio to hide them.
Victor had his hands on her soft, bouncy ass cheeks and was squeezing them. He caught her off guard when he spanked her. She was now taking her grandfather's penis completely inside and was working her ass up and down. Her pussy was incredibly wet and slippery and grandpa's fat member was sliding inside her with ease, despite its size.
"What a good little slut you are." Victor said and it made her go crazy.
She was used to playing with her clit and masturbated almost every day, but this was something completely different. The size of grandpa's cock was stimulating her in ways she never felt before.
Tina was riding her grandfather like a pro, her pussy swallowing his dick eagerly. Despite her being incredibly wet it was still a tight fit and Victor felt the walls of her young pussy gripping his penis with every stroke. It felt like heaven. Victor reached around and pulled her top and bra under her tits with one skillful move. She was overwhelmed with excitement and lust.
"Honey, you're gonna make grandpa cum inside you if you don't stop!"
That brought her over the edge. She started riding him wildly and Victor had a feeling the whole car was moving up and down with the rhythm of her bouncing ass.
She was moaning and thrashing her head as she started reaching orgasm, barely holding back from screaming with pleasure. Victor couldn't hold it anymore either. His cock throbbed and grew even bigger as he spurted huge amounts of cum inside his granddaughter.
"We're 5 minutes from the rest stop. We're taking a break there." Mike said.
"Yes, yes… YES!" Tina moaned while still orgasming.
"Oh Lord, honey. You sound like you're really cramped up back there." Mike said.
"Yes! Yesss…" She couldn't control herself and kept riding her grandfather.
Even though he just shot a huge load, his cock didn't seem to be getting any smaller. Tina could feel his warm semen inside her and was only half conscious from the amount of lust.
"We'll be there very soon so just hold on a little longer." Mike tried to comfort his daughter.
She finally stopped moving her ass and just sat on the big cock that was still buried deep inside her pussy. She leaned back on her grandfather with her firm, young tits still exposed.
As they were getting off the highway she finally started to gather herself and fixed her top and skirt.
As soon as they stopped Mike jumped out of the car. "I need to go to the toilet. You two stretch your legs."
"That was… crazy…" She said.
"Sure was." He shot back, smiling and his hands touching her smooth thighs.
"It might be a good idea for you to get off my cock before your dad comes back." He said.
"But it feels so good." She said playfully and wiggled her butt.
It was a rest stop in the middle of nowhere. Victor opened the door since that side was looking at the open field and no one could see Tina carefully raising herself from his cock, letting it fall out finally. She stepped out and let out a groan, her thigh muscles were tired from the hard workout she just had, bouncing up and down on a cock.
She grabbed some wipes and cleaned the cum dripping down her legs before noticing how her grandfather watched her and she smiled and blushed, turning away from him. She was still trying to process what just happened. She wondered what he did with her panties, but didn't ask.
Victor walked around the parking lot for a couple of minutes to get rid of the numbness in his legs and then got back to the car. Tina was standing next to their door.
Mike still wasn't coming back, but the sun was out and there was no other shade nearby except in the car so Victor sat back inside. Tina heard the sound of a zipper again and looked at him. His cock was out again. It was huge! Tick and long. She almost started drooling as she stared at it.
He grabbed her by the arm and turned her around with her ass to him and lifted her skirt. He gave her a good spank and she yelped with surprise. Feeling vulnerable and extremely horny, her whole body shivered. The taboo of the situation was intoxicating.
He pulled her to him and a few moments later Tina was back in her position on her grandpa's lap, with his cock inside her. She loved the feeling of her pussy being stretched and filled.
Five minutes later they saw Mike walking back to the car and she fixed herself up a little. With a cock in her pussy she just fixed her top and skirt to cover her legs and tried to act like everything was completely normal and they were just waiting to get going again. She expected her dad to get straight back behind the wheel so it caught her by surprise when he opened their door.
"You two already ready to continue?" He asked, not suspecting anything.
Tina felt her head spin being in this situation. Her grandfather's cock buried in her pussy as her father stood right in front of them.
"We're ready. Tina got nice and comfortable." Victor said and Mike closed the door and soon they were back on the road. They were barely half way and had a while to go yet.
Tina spent the rest of the drive slowly riding the big old cock, cumming twice by the time they arrived.
She was looking forward to spending time at grandpa's new house.
