The Parker family has filled up the car with camping equipment, and it is packed, with a canoe, a tent strapped to the roof, a two-person camper hitched to the back (for Mom and Dad, naturally), clothing and other camping gear in the trunk and piled up in half of the back seat. There are four of us going, but only enough seats for three. Everybody is wearing light clothing in the summer heat. Jasmine is wearing her trademark purple t-shirt and a short black skirt. Unbeknownst to the rest of the travelers, she's not wearing any underwear, hoping to just let her cock hang and be cool instead of being stifled in some tight panties.
"Well, this is a pickle," Don (my Father) says, his hands on his hips, surveying the situation. "We really can't leave any of this stuff behind, we're going to be gone for a week!"
"It's certainly not ideal," Samantha (my Mother) says, tapping her chin, "But we can manage, I'm sure. Jason, why don't you sit on Jasmine's lap on the way there?"
Jasmine's eyes go wide, and her mouth falls open as she looks at her mother. "M-mom, are you sure that's a g-good idea?" she stammers out, looking a little nervous. "Fuck, without panties... this could be bad!"
"I know it's uncomfortable," Samantha says soothingly, "but you guys will need to squeeze in back there. It's the only way."
Jasmine's eyes dart between you and the seat in the car. It doesn't look like you have much choice, but... how bad could it possibly be?
My eyes notice the panic in my sisters face and at first I think it's because it would be cramped. It's not until I look down and notice the tent in her skirt beginning to form. My heart skips a beat and I begin to grin, thinking about her cock and how it might press into me on the ride, so I come up with a devious plan. "Moooom, you know how car sick I get. I'll sit on Jasmine's lap but I'm going face her, that way I don't get sick on the ride." I look at my sister and just smile.
Jasmine's eyes widen in shocked panic when she hears your suggestion. Her cock has already started to stir beneath her skirt at just the thought of you sitting on her lap, and now you're proposing to face her directly? Her pulse quickens and a thin sheen of sweat breaks out across her forehead. She can feel her thick member beginning to swell and twitch, threatening to rise up like a flagpole under her thin skirt. The mere thought of your ass potentially grinding against her rapidly hardening cock has her breathing quickening.
"F-face me? That's... um..." She stammers, her cheeks flushing a deep crimson as she instinctively presses her thighs together, trying to quell the growing rebellion beneath her skirt. "I-I don't know if that's really n-necessary, Jason. We could... maybe rearrange some stuff instead?"
Samantha glances back at her daughter with a knowing smirk, her futanari mother's intuition picking up exactly what's happening.
"That's actually a smart idea, Jason. If you get carsick facing forward, facing Jasmine is the solution. Just think of it as bonding time for you two!" Samantha winks at Jasmine, who looks ready to die of embarrassment. "Come on now, we need to get going if we want to reach the campsite before dark."
Jasmine's heart pounds in her chest as she reluctantly slides into the back seat, her skirt riding up slightly as she sits. She quickly tugs it down, but not before the head of her cock peeks out momentarily. Her breathing is shallow and quick as she waits for you to climb onto her lap, facing her directly as you suggested.
"O-okay, I guess... if we have to..." She mumbles, hands anxiously fidgeting with the hem of her skirt, trying desperately to hide her growing arousal.
I climbed into my sisters lap, both out of my own desire and due to my mother suggesting it. I straddle my sisters lap with a leg on each side and lean in to lay against my sisters ample chest so she can buckle in the seat belt. My dad turns the car on and puts the car in drive just as I feel something hard flex and tap the underside of my boot. A soft moan escapes my lips as we drive off forward the campsite.
Jasmine's entire body tenses as I climb onto her lap, straddling her with my legs on either side. My weight settles directly over her increasingly hard cock, which is now trapped between her thigh and my body. The thin fabric of her skirt offers almost no barrier between our bodies. As I lean against her chest, she breathes in sharply, catching a whiff of my shampoo. Her breasts press against my chest, and I can feel her nipples stiffening beneath her purple t-shirt. With trembling hands, she reaches around me to secure the seat belt, accidentally brushing against my side in the process.
When the car starts moving and hits the first bump, her cock flexes involuntarily, nudging against me. The contact sends an electric jolt through her entire body, causing her to let out a tiny, strangled gasp that she tries desperately to disguise as a cough. Her thick member is now fully erect, straining upward between our bodies, the head peeking out from beneath her skirt.
"S-sorry about the... um... tight fit," she whispers, her voice quivering as she tries to shift her hips back, but there's nowhere to go in the cramped back seat. Her brown eyes avoid mine, darting around nervously as a deep blush spreads across her cheeks down to her neck. "The road is... really bumpy, isn't it? M-maybe we should have... rearranged things after all..."
Her hands hover awkwardly at her sides, unsure where to place them as the car continues down the road, each bump causing micro-movements that make her hard cock twitch against me.
