The tires of my car hummed along the blacktop, we were making good time, shouldn't take more than a couple of hours to get home. My 18-year-old sister Hanna and I were returning from our Grandma's house, she was getting on in years, and we liked to visit her often, and help her out, without her having to ask us.
Hanna, studying the map, said, "Lisa, If we take the next exit, it's a secondary highway, should cut about 30 miles off our distance."
I slowed and took the exit ramp, and on the secondary highway, the lack of traffic was a plus. We were making good time until we came over a hill and saw a large road barrier blocking the highway. There was a man standing in front of it, and he was holding a rifle. Fear shot through me, I wondered if I could swerve around the barrier, but no chance. Any attempt would probably flip our car into the ditch. I had no choice but to guide the car to a stop.
He sauntered over casually and tapped lightly on the window. I quickly rolled it down, we were in enough trouble as it was, I didn't need to piss off a man with a rifle.
"Afternoon ladies, who are you, and what are you doing here?"
I replied, "I'm Lisa, and this is my sister Hanna. Our map made it look like this road was still useable."
"Yeah, it's useable alright, but it's been made into a toll road, and I'm here to collect the toll."
He looked in, I saw his eyes sizing me up, taking in the view of my breasts, braless and just covered by a T-shirt with a gap in the front, giving him a good look at the cleavage between my 36C chest. His eyes wandered lower, getting a look at my shorts, and my tanned legs. His eyes flicked over, and he took in my sister, his eyes taking a long look at my sister's 34C chest, and then traveling down to her skirt. Hanna was shaking, scared, and I did my best to put up a brave front, for both our sakes.
"And what would the toll be?" I inquired, doing my best to keep my voice steady, hoping he didn't want to take all my money, or worse yet, our car.
"Well, how about that sweet little sister of yours? If she comes on out here and gives me the very best blowjob she can, the toll will be paid in full."
I gaped at him, fuck, I hadn't expected this. Hanna was shaking, terrified, pressed back tightly against the passenger side door.
"Oh yeah, she's all ready for it! Yeah baby, get them sweet pink lips of yours all slicked up, and come on over here and let me slide my stiff cock between those tight, slick lips of yours, right into your sweet little mouth. Do you like to swallow the cum baby? I've got a big, juicy load, all set to fill your sweet mouth baby!"
I said, "You can't do that, she's only 18, she's still a virgin!"
He replied, "What, she's never sucked a boy's cock? And who said anything about whether she's still a virgin. I just want her to suck my cock, I'm not gonna bust her open!"
