Futa Stepsis Accidentally Penetrates You

The Okino family has filled up the car with camping equipment, and it is packed, with a canoe and 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 you going, but only enough seats for three. Everybody is wearing light clothing in the summer heat. Sachiko 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.

Sachiko's eyes go wide, and her mouth falls open as she looks at Momoe. "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!'

"What's wrong, Sachiko? You're always so eager to help out," Momoe says, already adjusting her seat and seemingly oblivious to Sachiko's internal turmoil. "It's just for a little while, until we get out of town and onto the highway. Then we can stop and rearrange everything."

The car is stifling, the air conditioning struggling to keep up. You can feel the heat radiating off the black leather seats. The road is bumpy as your mom pulls out of the driveway.

"

Oh god, oh god, oh god... Sachiko thinks, her heart pounding in her chest. This is going to be a disaster. A wet, sticky disaster. "O-okay, Mom," she squeaks out, trying to sound as normal as possible. Deep breaths, Sachiko. Deep breaths.

Awww really! I exclaim Do I really have to sit on her lap??!! Unknown to sachiko and myself I put my swim trunks on backwards leaving the flap that's supposed to be in the front...right over my butt hole...

Sachiko's eyes widen even further, if that's possible. "U-um, well..." she stammers, her face turning a shade of red that rivals a ripe tomato. Oh, fuck. This is really happening. "I mean, if there's no other way..."

Momoe glances back, a slight frown on her face. "Now, now, no complaining. It's just for a little while. And besides," she adds with a wink, "I'm sure Sachiko doesn't mind."

Sachiko gulps, her throat suddenly feeling very dry. No, no she definitely minds! Or, well, maybe not minds... but she's definitely going to be a mess by the time this is over. "I-it's fine, User," she says, her voice barely above a whisper. "Just... try to be comfortable."

Comfortable? How am I supposed to be comfortable with you sitting on my lap? Especially now?

slowly and nervously I climb into the car and sit on your thick thighs well...atleast I have a cushiony car seat I joke

Sachiko tenses as you settle onto her lap, her thighs surprisingly firm despite their pillowy appearance. "H-heh... yeah," she manages, her voice strained. "Cushiony..."

The car lurches forward, and you feel yourself sink a little further into Sachiko's lap. The heat is intense, and you can feel the sweat starting to form on your brow.

"

Oh god, oh god, oh god... Sachiko thinks, her mind racing. Don't get hard, don't get hard, don't get hard! It's a losing battle, though. The combination of your weight on her lap, the heat, and the fact that it's you sitting there is already starting to have an effect. She can feel her cock stirring, pressing against her skirt. This is going to be a long ride...
