Grandpa's Lap: Backseat Santa

"Do I seriously have to be an elf?" I asked, still not believing my mother had volunteered me to assist my grandfather at a charity event.

"Yes," she said, annoyed by my constant complaining. "If you don't want to do it, go and tell your grandfather that."

She knew I would do anything for Grandpa, and would never say no to him, but this was possible social suicide. I sighed. "You know I can't say no to Grandpa." While this was always true because my grandfather was such a wonderful man, it was especially true in this situation, when he'd be returning to his role as Santa after a two-year hiatus following my grandmother's death... the love of his life.

"I've never been able to either," she said in a pensive tone that I took to also be related to thinking about her own mother. For many years, my mom had alternated playing the elf with my aunt, and a couple of female cousins. This year she was taking on her mother's old role as Mrs. Claus.

"Fine, but if anyone I know sees me dressed like this..." I stopped to look at myself in the mirror. The outfit was way too small on me in the first place... the skirt so short it would definitely get looks. But it was the green pantyhose and hat that really made me look ridiculous. "Well...I'll never forgive you."

"You look adorable," she said, with a motherly smile, as she looked at me in the hideous seasonal outfit.

"Yes, every eighteen-year-old wants to be called adorable," I said.

"Well, your outfit is a lot better than the one I am wearing," she countered. In some ways this was true, as the old-fashioned dress, white wig, and glasses made her look significantly older than the forty-three she was.

"Maybe," I half-agreed, although, if I were wearing her costume, at least I might not be recognized by people who did know me.

"Plus, because you're taller than me the costume is as short as the usual outfits you wear," she pointed out.

"Now is the time you approve of my attire?" I questioned, shaking my head.

"Not approve," she said, "just pointing out it isn't much different from your usual fashion choices."

"I hate you," I said in what had become an almost automatic, mostly jokey response to any criticism from her about my wardrobe or behaviour. Any real ill feeling being strictly based on not liking her having me dead to rights on the costume length issue. I did like to wear outfits that showcased my long legs and since, as an ongoing act of teen rebellion, I usually chose not to wear panties, there was often the risk of exposing my naked ass. Of course, beyond tweaking my mother, I also liked the freedom of going commando... especially if it meant I could just flip up my skirt for a quick fuck on a date or to compel my good friend and lesbian pet, Mary, to eat me out.

"Oh, you love me," she said in rote response to what had become a bonding ritual between us. We'd had a few rough years when she'd sent my dad packing back when I was 14 but we'd gotten past it and were quite close now, especially since my brother had left for college.

"I tolerate you," I responded, the term I always used in this situation.

"Yeah, yeah." She waved her hand dismissively at me.

"And these pantyhose even have a hole in the crotch area," I pointed out. When I'd discovered it, I'd thought it would be a cool idea for quick, easy access to my pussy on a date... but now it was just something I was going to have to be careful about at a Christmas fundraiser at the children's ward at the hospital.

"What? They ripped the hose?" Mom snapped. The 'they' she was referring to were one of Mom's cousins and his family who had filled in for Grandpa and us the last two seasons. While Grandpa wasn't up to playing Santa himself while grieving Grandma's loss, the family tradition of supporting the children's ward was too long-lived to let it fall aside.

"Do you have another pair?" I asked.

"Do you know how hard it is to find green pantyhose?" she said. "And besides, we don't have time. Is the hole really big?"

"No, I guess not," I groused.

"I always wear green panties with them anyway," she offered, "didn't you choose a matching pair?" I decided it might not be the right time to announce I was sans panties. But, since I actually had a couple of pairs in various shades of green, I considered rethinking my commando approach. But then Mom squelched that idea.

Looking at the clock, she said, "Oh, we really need to get going, we still have to pick up your grandfather."

"Pick him up? I thought he was meeting us there?" I said, as I scurried after her as she hurried to her car.

She said, "He texted me while I was packing the car and said the garage needed to keep his car another day to fix some problem, so, he's riding with us."

I stopped and stared in wonder through the car windows. It was jammed full with all the raffle items and kids' presents.

"Sorry," said Mom. "I had a couple of tall, potted plants and could only fit them on the floor in front of the front passenger seat. You'll have to sit in back behind me."

I opened the rear door on the driver's side and saw that the whole center and right side of the rear seat were covered with packages. "How are we even going to fit Grandpa in here, there's barely enough room for me?" I questioned.

"We'll make it work," she said, as she slid in behind the wheel. As I got in behind her, she said over her shoulder, "Look at everything back there and see if you can think of how things could be rearranged."

"Okay," I said doubtfully, taking in the carefully constructed pile that almost went all the way to the ceiling. Unfortunately for this situation, Grandpa didn't live very far away, and I hadn't come up with any solutions by the time we arrived to find him already waiting outside in his Santa suit. It really was a high-class-looking suit, although hanging a bit baggy since Grandpa was actually still a very fit and dynamic man. He was holding some kind of small bundle with straps that I guessed he would stuff inside the coat for his belly when the show began. I got out of the car, went over to him and gave him my usual close, heartfelt hug... he and my now-in-Heaven grandma were by far the two family members I was closest to after Mom.

He held me out at arm's length and ran an appraising eye up and down my green-clad frame. "I can hardly believe you fit in that outfit," he chuckled, "but you look great."

Mom had joined us on the sidewalk and looked at me with a critical squint to her eye. "Well, I'm not so sure anymore that she does fit in it," she mused.

Although just a short while ago I'd been arguing against the costume, I naturally had to go counter to her opinion now. "It fits perfectly fine," I said, wiggling my ass at my strait-laced mom.

"Mandy," she said, shaking her head.

"Girls will be girls," Grandpa said, as we walked around the car. "Don't even get me started on the outfits your mother wore when she was your age."

"Mom, did you dress scandalously when you were a teenager?" I questioned with a mocking tone.

"Dad, look what you did," Mom sighed.

"Well, just saying, you are kind of the kettle calling the pot black," he said.

"Well, Mother," I said, "I think we need to have a chat."

"For the record it was the nineties and things were different," she said.

"You're grasping at straws," I teased as I opened up the rear door and exposed the mess inside to Grandpa.

"Dad, I didn't realize how much stuff we had in the car, and I can't think of any easy way to rearrange things in time. Would you be okay to just have Mandy sit in your lap?"

"I told you how much stuff we had," I pointed out, even as I considered her solution to the problem.

"That's fine," he said, "it will get me warmed up for the long night ahead. Ho, ho, ho."

"I'm a little bigger than most of the kids," I pointed out.

"Have you seen some of these young kids these days?" he countered. "I think their parents are raising them on potato chips and soda pop." As my mother and I laughed, he slid into the seat, squeezing his soft belly bag between the top of the stack and the roof. Oh, well, that should make it less likely to fall over on us, I thought.

Then he turned to me and patted his thigh. "Slide that little butt on in here," he said with a surprisingly roguish tone, I laughed again, not really bothered about having to sit on my grandpa's lap, as I still often snuggled up against him on the sofa when watching movies together during my visits to his condo a couple of times a month.

However, as I went to get on his lap, it became glaringly apparent that my skirt was indeed quite short. I tried to hold it against me but there was no way he didn't get a peek at my green pantyhose-clad ass and probably realized I had nothing on underneath since they were more sheer than one might expect for green elves' stockings.

As I struggled to wiggle my way in with some semblance of lady-like movement, he finally just took a firm grip on my waist and positioned me on his lap.

As I settled, my eyes went wide as I realized there was a significant lump pressing directly against my butthole. Was I sitting on something hidden in the folds of Grandpa's costume... or was I sitting on Grandpa... on his dick?

Mom closed our door, then got into the driver's seat and started the engine. She laughed as she said, "Get comfortable."

When she pulled away from the curb, the sudden movement drove me deeper into Grandpa's lap and I began processing the reality that yes, I had a semi-hard dick pressed up against my asshole, that it seemed to be a quite large dick... and that it belonged to my grandfather.

If it hadn't been my grandfather, just one of my fuck buddies, with his strong hands controlling my hips and his dick seemingly growing harder beneath me, I likely would have found a way to get that dick into my pussy through the convenient hole in the pantyhose. Of course, right there in the car, I'd blown a guy in an Uber before, hadn't I?

Actually, I'd always been turned on by exhibitionist sex and to fulfill that kink, I'd had Mary eat me out in a changing room at a Victoria's Secret, been fucked in a coat closet right off the main room at a house party, and even jerked a guy off in a movie theatre (he came all over my hand, and I'd licked it clean right in front of him). The idea of backseat sex with others in the vehicle was suddenly intriguing and exciting. And truth be told, maybe even more so because it was my grandfather back there with me, not to mention my mother up front.

So perhaps it wasn't surprising that my pussy betrayed me as it tingled when my grandpa's dick, his seemingly big dick, pressed against my privates.

The next shock came when Mom swerved suddenly, causing my position to shift so that the pressure moved to my taint and the bottom of my gash and then Grandpa's dick flinched. I couldn't help but moan ever so slightly out of shock and pleasure.

"Sorry about that, you okay?" Mom asked, as she rolled up to a red light.

"Yeah," I responded, as my grandpa's dick flinched again. The first time I thought it was a coincidence but two in a row had me confused... and even more confusingly... turned on.

"Good, get comfy, according to the GPS we have a twenty-minute drive," she said.

"Twenty minutes?" I asked, thinking it was a ten-minute drive, fifteen minutes max.

"Looks like construction," she said. "Probably going to be some bumpy roads and single lanes."

When Grandpa's cock flinched beneath me again, pulsed like some large snake getting ready to uncoil, I thought this time it couldn't be an accident.

"Okay," I said, getting turned on by this surreal situation. I mean my grandpa was a good-looking man still, a silver fox one of my friends had said after declaring he was hot. And I did find older men attractive, having fucked one of my friend's dads who really gave me the fuck of my life and treated me like a whore (which I didn't know I liked until he called me names and just plain used me). But Grandpa was in his sixties and well... my grandpa. And while I may be a bit of a kinky girl, incest seemed a whole other level of kink with far more serious repercussions.

As if some incestuous Cupid was stirring the pot, we suddenly hit a bump on the road and his cock pressed right against my pussy as his hands on my hips held me in place, making me moan again.

"Sorry," Mom said, "I didn't see that bump."

"All good," Grandpa said, his dick again flinching directly on my increasingly wet pussy. Was I going to leave a wet spot on his Santa suit?

"Yeah, it just startled me," I said, although I was referring to Grandpa's raging hard-on pressed against my pussy... only his Santa suit preventing something really inappropriate from happening.

"I'll try to be more alert," Mom said, "but I gotta warn you, the road ahead looks a little rough."

"We can handle it," Grandpa said, as he again flinched his dick and gave my hips a squeeze.

Shockingly turned on, and my naughty persona coming out, I decided two could play this game. If he was going to tease me, I would tease him.

"I'd better get a grip then," I said and grabbed the roof handle above the door with my left hand and put my right on the corner of Mom's seat back. With this leverage, I moved my hips back and forth to feel his dick rubbing my pussy, although as I teased him, I realized I also teased myself... I had to bite my lip to control another unexplainable moan.

Grandpa responded with three rhythmic cock throbs right against my pussy.

Not to be outdone and not thinking logically as my pussy burned, I responded in sexual Morse code by grinding my pussy back and forth on his crotch three times.

This time he groaned slightly, but not loud enough for Mom to hear over the radio that was playing 'Summer of 69'. I realized she'd tuned into a classic rock station that was playing songs from Grandpa's young days.

My sweet grandpa, who had apparently grown crazy horny after living alone for two-and-a-half years since Grandma passed, upped the ante, apparently taking my playful teases as real signals of permission, and moved both his hands to my nylon-clad legs.

When I didn't move his hands away, giving non-verbal permission, he slowly began to caress my legs... any chance of all this being innocent coincidences fading as his hands slowly moved up my thighs and under my skirt.

So, turned on, even though he was my grandfather, I moved my left leg over his, which spread my thighs apart, inviting him to continue his inappropriate meandering under my suddenly rather conveniently short outfit.

His cock flinched again as his hands began ever so slowly rolling my skirt in on itself. I looked up in sudden panic but realized that Mom couldn't even see my face in the rear-view mirror if I didn't lean over to the right, and because we were directly behind her, she certainly couldn't see what was going on in our laps. I couldn't believe this was happening. I couldn't believe I was allowing it to happen. I couldn't believe I was getting so turned on. I seriously was wanting his hand to touch my pussy as I spread my legs even a little bit further in clear invitation.

As we rolled to another red light, Mom said, "You two are pretty quiet back there, you still doing okay?"

"Yes, sweetheart, we're doing fine," Grandpa spoke for just the second time, even as his fingers exposed the gusset of my pantyhose, putting him ever closer to my needy pussy.

"Yes, Mom, doing just fine," I agreed, trying to communicate to Grandpa that I was good with what was occurring behind my mother. "It's much more comfortable than I expected. Just relaxing and taking in the scenery, I guess."

"That's good," she said, as she started driving again. Grandpa indeed took my response as formal permission to really cross the line, and his right hand swept across the front of my crotch, quickly finding the open hole in my last line of defense. He took his left hand and lifted it up to my left breast and squeezed. Looking at the rear-view mirror again, I realized that Mom really couldn't see what was going on on the left side. Grandpa used his strong grip on my tit to pull me back against him. I could feel his hot breath on my neck as he took control.

Although I was so young, I'd always been strong-willed and that had continued right into my first sexual encounter as an adult. I'd racked up a number of encounters since then (some might say a shocking number, I prefer a confident number) and had always been in control during sex (except, of course, for that whole whore-to-my-friend's-dad episode). Now, however, I was completely under Grandpa's spell as his fingers rubbed my clit after finding the suddenly really convenient hole in the pantyhose. After a few seconds he moved a finger directly to my pussy lips, their juicy wetness making it very clear what I thought about my own grandfather molesting me.

I desperately tried not to moan and alert Mom to the incestuous act taking place right behind her as Grandpa began to finger me. Alternating between opening me up with his fingertips and using a fresh coating of my slime as lube for rubbing my throbbing clit, Grandpa showed digital skills I'd never felt under another man's hands.

He was having trouble getting deeper, though, because of our position and my pantyhose gusset and it was getting frustrating for both of us. His tit-squeezing hand moved to my crotch, and he gave a loud stage cough off to the side to cover the sound of nylon ripping. I almost came right then. Instead, I began swiveling my hips to grind harder against his cock and try to help his fingers fuck me even deeper. Unfortunately, it only seemed to be making me crazier in frustration and I let out a little whine.

"Still good back there?" Mom asked, as my noise came out just as a song finished playing and commercials came on.

"Fine," I said. "I think Grandpa and I are just finding it hard to get in a comfortable position." I thrust again at his fingers to let him know I was enjoying this but was a little frustrated by the lack of more penetration.

"Yeah, maybe we need to adjust positions," he suggested, pulling his finger out and moving his hands to my hips.

"Should I pull over?" Mom asked, just as Grandpa lifted me off his crotch and gently pushed me to his right and forward, so my head suddenly stuck between the two front seats, causing Mom to twist her head and look at me in surprise. I gave the best shrug I could while grabbing the corners of the seatbacks and putting pressure on my right foot on the floor as I strained to hold my butt up off Grandpa's lap.

"No, no no," Grandpa said, almost sounding like ho, ho, ho. "The kids are counting on us; we can't be late. How much time do we have left?"

Bizarrely, this irked me. Not the not stopping, I knew that was a bad idea. But the fact Grandpa seemed more concerned with the little kids who'd soon be sitting on his jolly Santa lap rather than the grown granddaughter sitting on his horny Grandpa lap.

"Yeah, still says fourteen minutes," Mom informed us.

"Don't speed or anything," Grandpa said, "just get us there safe and in one piece."

"Will do," Mom said, smiling crookedly at me in my predicament.

"Umm, Grandpa...?" I said, really wanting to get out of this awkward position and back on his lap. Although now that I was all twisted and didn't have his fingers inside me, my mind was clearing and my common sense returning, reminding me just how wrong this was.
