Luke drives for over fifteen miles with Kathy giving him a blow job, slurping up his manhood. She takes periodic breaks in between, sucking off his cock and jerking him off. Luke takes his eyes off the road to look at his grandmother each time she sits up to catch a breath. Her mouth drips with saliva and she smacks her lips each time. Kathy then swivels her tongue around his helmet for a few minutes. Luke had an orgasm building up for quite some time. The sensation of his grandmother's tongue on his tip with her hand slowly stroking his shaft is his sudden breaking point.
"Grandma, I'm going to cum!"
Kathy swallows up his rod and stretches her mouth to accept her grandson's meat. She wants to swallow his milk. All of it! With her head bobbing up and down his cock, Luke briefly closes his eyes feeling the rush of his orgasm approach. Kathy grunts when the first wave of Luke's seed hits the back of her throat. He feels his cock spit out many spurts of semen into his grandmother's mouth. She swallows each load, continuing to slurp him up with her head moving up and down. Luke calms down after his orgasm subsides. Kathy eventually lets go of his penis and sits upright back into her seat, catching her breath.
"Delicious honey!" Kathy says proudly.
"That was incredible!"
"The thrill of sucking you off on the road darling, it made me feel so alive!"
Kathy takes a wipe from her glove compartment to clean herself. In a swift motion, Luke pulls his jogging pants back up. He takes a notice of Kathy's denim skirt pulled up. All her moving around in the last twenty minutes or so pulled her skirt up higher to her mid thighs. Luke feels his heart beat faster, grabbing hold of Kathy's left thigh with his free hand. He rubs her smooth skin. He casually slides his hand in between both of her tanned legs.
Kathy reclines her seat back and allows her grandson to do whatever he wants with his hand. She spreads her legs out wide to allow easy access for him to explore her womanhood. She stays quiet, hoping he'll reach her soaking cunt and feel just how wet she is. She can see a smile on the corner of his face building up as he drives with the cruise control still in operation. They both enjoy the silence inside the vehicle, letting the sexual tension escalate between the two of them. Luke slides his hand further down to Kathy's crotch and touches her pussy. His two fingers are greeted by her wet, glistening vaginal folds. He teases her by rubbing his fingers against her clit. Kathy shifts her body upright trying to keep herself contained. Just as easy as she was able to find her grandson's sensitive spot, he found hers. Luke knows he's in control now. He enjoys this moment, taking his time rubbing her gently with two fingers. Kathy covers her mouth with one hand and uses the other to pull her skirt higher. She does the best she can to not scream, audibly grunting. Luke stops rubbing her clit a few times to feel just how wet Kathy is. He moves his fingers in a scissor-like motion to see her sticky juices ooze in between them.
"Darling! I'm going to make a mess inside! I'll literally cum all over your fingers if you stick them inside of me right now!" Kathy says out of breath.
With a smile on his face, Luke slides his fingers down his grandmother's vagina and finds her slit. She's so wet, he can feel the tips of his fingers easily slide into her tight hole without much effort. Luke keeps his eyes on the road, shoving his fingers deep into Kathy's pussy. She does a terrible job at maintaining her composure. She moans and shakes her body around in her seat. Luke feels his fingers turn into a slip and slide. The longer he fingers his grandmother, the easier it gets for them to slide in and out of her snatch. Luke takes a brief look down to her crotch and can see her juices dripping down in between her legs and onto her seat. His fingers are covered in her post orgasm juices. Luke takes his hand away from his grandmother's crotch and shoves her pussy juice fingers into his mouth. He savors the taste, letting her mature vaginal flavor sit on his tongue before gulping down her juices.
"Delicious!" Luke says to Kathy with a grin.
"You are something else darling!" Kathy says still out of breath.
They continue down the highway when a sign for a rest stop comes up. The rest stop is just four miles out and Luke has an idea for he and his grandmother. Their first detour! He loved how delicious Kathy tasted. He hasn't had enough just yet though.
"Grandma, let's stop at the next rest stop ahead for our first detour!"
"That sounds like a great idea darling! What do you have in mind?"
"Your oral skills are amazing! It's time I show you some of mine!" Luke says to her.
The exit for the rest stop approaches. Luke pulls off the interstate. He and Kathy quickly run to the restroom for a quick bathroom break. He waits for her by her vehicle and does some quick stretching exercises to give his legs a break from hours of sitting. Kathy comes out soon after. They get into her SUV and drive to a desolate area of the rest stop for privacy. Kathy had gotten into the back seat of the vehicle. Luke steps out of the driver side and makes his way to the back seat, opening the rear door on his side. Kathy has her long sleeve shirt pulled up with her breasts exposed. She doesn't have a bra on. She sits back up against the window of her car with her denim skirt on the floor. She sits naked against the window of the back side door on her side with her legs lying across the back seats. Luke jumps into the back of the vehicle and locks the car. Kathy takes her legs and lifts them, spreading them wide open for her grandson.
Luke takes a notice of Kathy's pussy, visible to him for the first time. They fucked last night in the dark motel room. While he felt just how amazing her snatch was, he never got a look at it. Luke turns his body and gets close to his grandmother putting his face in between her elevated legs. Her vaginal area is clear with a more pale tone than her tanned skin. Her pubic area is neatly trimmed with grey hair in the shape of an upside down triangle. The bottom tip of her triangle stops just over her clit. Her slit looks tight with small vaginal folds hanging loose at her entrance. For a seventy year old woman, Kathy has a vagina that looks remarkably sexy compared to women more than half her age.
"Do you like it?" Kathy asks her grandson.
"Grandma, I can't lie to you. This is the most beautiful pussy I've ever seen. Don't ever tell Sara I said that," Luke says with a chuckle.
"This is our secret darling, remember? I think it's time to show for you to show your grandmother how you eat pussy. Fair warning though, it won't take much for you to make me cum again. I haven't been this horny in AGES!!"
Luke takes one last glance at Kathy's elegant pussy before diving into her. His arms are underneath both of her thick legs and he uses them to spread her legs wide for him to get deep into her snatch. With his nose buried in her pubic mound, his tongue slips out of his mouth and finds her clit. Kathy is unable to stay quiet. She lies back against the back window of her vehicle and moans while stroking her grandson's hair. Luke feels her legs shifting from the oral stimulation she's receiving. Her legs squeeze his head at times while his tongue flicks her clit. Luke then uses his tongue to part her vaginal lips open, slipping his salivating member into her slit. Kathy moans, softly whispering for Luke to not stop. With encouragement to continue, Luke moves his head in a clockwise motion, tonguing her deep inside her pussy. Luke enjoys the familiar taste in his mouth from earlier when he fingered her. He takes deep breaths when he can and is hit with her natural feminine scent, driving him wild! While his mouth does most the of the work, Luke moves his right hand lower to her crotch area and discreetly slips two fingers into her slit.
Kathy lets out a loud grunt and begins to purr. Her grandson eats her wet snatch with two of his fingers deep inside her. She can't believe it! Even after all that's happened in the last twenty four hours, she can't believe that her grandson is giving her oral pleasure. She's moments away from an orgasm. Kathy lies against the rear door of her SUV, focusing on her present situation. Luke's fingers thrust in and out of her with slow, deep motions. His tongue swirls all around her clit and into her vagina. Her legs begin to shake uncontrollably, preparing for her eruption bound to happen shortly. She feels the sensation of her grandson's facial stubble rub against her clit and crotch as his tongue glides up north to her grey pubic patch. She doesn't warn Luke about her sudden arrival as her legs buckle and tighten, squeezing his head.
"YES!!! GOD YES DARLING!!!" Kathy shrieks with a high pitched yelp.
Luke was not prepared for his grandma's orgasm. He's temporarily unable to breathe with her legs locked against his head. He slips his tongue back into her slit, feeling her vagina tingle. He's flooded with her orgasmic juices as they pour out of her womanhood. Luke remains calm unable to breathe with his nose and mouth drenched in her fluids. He slurps up her cunt juice all around her slit and exterior vaginal area. After what felt like an eternity, Kathy releases her tight grip off of Luke's head and spreads her legs out. Luke pulls his face back, catching his breath. He looks at the outcome of her orgasm with her pussy glistening with his saliva and her juices. Her pubic hair is soaked with juices flowing out of her. Kathy catches her breath as well, unable to speak. When Luke smiles at her asking how she's doing, she just gives him a thumbs up. Wanting to get a taste of herself, Kathy leans up to her grandson and kisses him. They share a deep kiss with plenty of tongue, savoring the flavors of her pussy.
After a few minutes spent recovering, Kathy puts her skirt back on. Luke steps out of the vehicle and stretches one more time before they get back on the road. They had stopped for a good half hour. They exit the rest stop and get back onto the interstate continuing on with their journey.
