Inescapeable Backseat Blowjob

(Part 1 from 1)

Note : This story is completely fictional!

Breck, Bobbie, and their parents were out the door heading to the family car for a long trip out to the campground for the summer. Breck hadn’t really wanted to go, as it was always the same old boring thing. But Bobbie had convinced him otherwise. Standing next to the car as he was complaining she whispered in his ear “if you promise not to complain or tell I’ll make it worth your while” in a sexy voice ending with a nibble on his ear. The two were brother and sister, but as Bobbie was the total freak with blond pig tails, a very short red plaid miniskirt, and a brazier for a top (one that looked like a red glitter embroidered bra and nothing more), and a gothic attitude, you could never tell. Breck on the other hand was a laid back straight arrow with a porn collection to keep him company. Naturally they had grown up protecting each other and had given their parents the obvious impression that it was what they were all about, but when they gotten their hormones they had been crushing on each other ever since, hiding it behind a veil of protectiveness.

All four got into the car, an SUV, on their own respective sides, and the journey was on. A 3-hour trip with nothing to do but watch the scenery, but the sister never could just sit still or sit back and watch. They’d been on the road a half hour when she yawned like she was tired and laid down on Breck's lap looking first out the front windshield, then inverting her face to Breck's crotch. After a minute she began shaking her head left and right against his groin as if she was tired and trying to ward off her inability to be comfortable, but the more she dug in the more she slowly began to arouse his cock. When she felt his cock begin to get some feeling she stopped for a second. Surly Bobbie was just trying to get comfy in his lap, Breck thought, and he relaxed trying not to let his deeper thoughts get to him.

Then she used her teeth to slowly, quietly, open his zipper and did that whole shaking thing again. Breck felt the rub of the fabric, the area where the zipper was open and alternately the air rushed in and fine, blond hair rushed in. He looked down and mouthed “what are you doing” to his sister. “Nothing” she mouthed back as if he were being absurd. Still slightly aroused with a dick slowly growing he did his best to make it quite. Then she stuck her tongue in and began fondling his balls with it. The little tricky minx, he thought. Well, maybe she was only having fun working him up for fun; after all it would be something she would do. When he was half-hard she quite fondling hid balls to maneuver his cock into her mouth using only her tongue. The big brother looked down at her for a glance to see what she was planning to do. All in a way not to distract their parents she revealed only the front of her skirt showing she had no panties whatsoever on without showing her parents the back of it. She made sure her face was covered by a tail and that her mouth, which was air sucking his cock, vacuuming it in, had covered it completely, and put a finger next to her mouth and his cock to signal a silent secret with a wink at him.

Was this how she was going to make it worth his while? By blowing him? He looked around and found Bobbie had done it all right. Neither parent had any suspicion whatsoever. Of course this meant she could do anything she wanted to him, but he couldn’t do anything to her except come or tell. They had on occasion talked about having sex, fucking each other, but both had always wussed out being siblings. Now shortly after high school, at the end of their teenage years she was going to blow them in front of their mom and dad.


All he could do was try to keep it from happening, but the more he thought about that and felt himself the more aroused he got. Gradually he felt his cock grow in her mouth from being against her tongue where, in her mouth, she rubbed it along, and the moisture made it grow a little faster. He felt the texture every time she “licked” his cock as he tried desperately not to grow or get any harder. Breck felt the whole; length of her tongue and ceiling of his little sisters mouth toward the back of her mouth where he could feel himself growing and oozing to a tight hole. He grew past her right to the back of her mouth and into her throat. When he felt himself stop she opened her mouth wide and shoved her head down as far as she could, deep-throating her big brother for all she was worth. Already he was starting to sweat from worrying. Breck remembered she’d told him once that she found manly sweat almost as intoxicating as million-dollar cologne and knew he might be in trouble. She resumed her regular position staying just hidden enough not to be noticed from the front seat before beginning to purse her lips and teeth alternately, though pleasantly, in a pulse rhythm until he had his own pulse going and she went with it.

The brother began rubbing down her side both to send back the pleasure and to prove to his parents how comforting a protector and brother he was. Also he wanted to see who might notice first. His mother looked back at them with a “picture perfect” smile on her face. “You two look so precious together” she explained and turned back around. His father turned the radio on low and Breck bent down to whisper to her “can you please stop. This is high risk” to which she shook her head, never taking his giant cock out. He got the point with agonizing pleasurable friction. She meant no and she meant to intentionally do it that way a warning. “So, what happens if they stop and want us to go in somewhere” and again she shook, but this time she also put her finger back to her mouth. Obviously she was horny and wasn’t going to let go come hell or high water, or maybe until he orgasmed. Either way his choices were few. Since it was one of the few things he could do he looked well at her crotch with a look of surprise and fear. Even though there was nothing strange to look at there, and began to rub his finger along the ridges of her pussy, back and forth and left and right a little. Again she deep-throated him and he started circles on her pussy lips.

Then he inserted a finger and the blowjob she was giving him became more intense as she closed her mouth to almost scrape her lips across his dick. “Notice something wrong, son” his father asked from the front in the mirror. “I thought I saw something dark on her leg, but its gone now. I think I rubbed it off” he lied.

After a while she quite sucking and mouth pinching his dick and just rested, but Breck couldn’t tell whether or not she was faking or sleeping. “Mom” he called and she turned around. “I have something to asked” was all he got out before the wicked sister really tightened her mouth and rubbed with what felt like it had to be everything she had. “Yes son” the mother turned around. He tried not to make a face, but the renewed vigor of the blowjob left him thrilled, weak, and obvious. “Are you okay, honey” the mother asked. “Yeah, just uuh”, he took a few deep, long breaths, “heartburn. When are we gonna be at the next stop or gas station” he asked faking a calm peacefulness he felt in a way other than what his parents perceived. “It will be a while, dear” his mom explained and turned back around.
Behind the drivers seat he raised his lap, pelvis, groin, and all, to whisper in her ear “what are you going to do if we stop and they want us out” and again she shook her head back and forth as if she were simply uncomfortable. He got the picture, after the torture. “You know eventually they could catch onto us” he told he and she gave the quiet signal again to tell him not to give them a reason. He’d had basically the same hard on for an hour now which made it a new record for him.

They were half way into the trip when they stopped at a gas station with a museum next to it. In the rearview mirror the father looked at the sons face. “Hey, son, do you want to go into the museum over there. They usually have early mechanical ideas, at work, and all kinds of different things” he asked his boy enthused. It was kind of late at night and he wanted to just to see, but his craving to orgasm was powerful. Maybe she’d suck him off and they'd be done before Breck's and Bobbie’s parents got back. He was achingly stiff. “Sure” he began before feeling teeth pinch down on his cock. His mother looked at him, then looked down at his lap with him as her daughter started to whimper and moan like she was having a bad dream.

“Well, maybe I’d better stay here and watch over her in case she wakes up” he explained sweating knowing that if his parents didn’t see her sucking his dick yet all they’d have to do is lean toward him a little bit more. Suddenly she her mouth went loose over his jeans.

Curiously the mother looked at her son. “Does she usually sleep with her mouth that open over there” she requested and he just shrugged. Breck knew the mother was a little suspicious, but the parents left the car anyway. “Are they inside” Bobbie asked with her eyes still shut. “Yeah” the brother answered as he saw them go inside. His little sister got her knees on the seat and blew him toward heaven stopping only to have him warn her of when they came back.
