Jenna watched the trees rush by, as they escaped the hotel grounds. Mike was already starting to joke about what had happened back there, but Jenna knew him well enough to recognize her brother's coping mechanisms.
She was still in disbelief about what had happened over the weekend. That somehow the abandoned hotel had been transformed into a vibrant, thriving place again. That she had hooked up with an Olympic-level hottie, had amazing sex with him seven times, only to wake up on Monday morning and find out that it had been Mike she'd been fucking the entire time. Or at least that's what they had concluded, when they had awoken in a compromising position, with DNA evidence leaking from Jenna's cunt. Jenna was still struggling to accept what she had just experienced. She hadn't believed in ghosts before this weekend, and she still didn't want to, despite so much evidence. But how else to explain it?
Still, underneath Mike's jokes, Jenna detected something else, something left unsaid. Possibly something big, something illicit. The way he looked at her now wasn't the way he ever had before. When he glanced her way, she worried he wasn't going to be able to tear his eyes away, and that they were going to crash on this winding rural road. As a bigger girl, with acne that outlasted her teens, Jenna wasn't used to that kind of admiring gaze from guys, least of all her own brother. It was a little intoxicating, even if it was a bad sign for their sibling relationship.
Could he actually be attracted to her? Lusting after her? Could he actually want to fuck her, in particular, on purpose, knowing it was her, and not just in the stead of someone else? Jenna knew it was wrong to even pose these questions, wrong for them to turn her on, but there it was.
"First stop, pharmacy," Mike said, and he reached across and took her hand in his. The implication was clear, that after she got the morning after pill she very much needed, they could stop somewhere and fuck each others' brains out, before returning home, to their parents and their formerly-normal lives. It was an absurd suggestion, wasn't it? It was, right? But his hand on hers set her heart racing, her nipples firming up against her bra, the warmth and moisture between her legs starting to run.
Before this weekend, it would have surprised her that anyone would have wanted her, with her pimply, rounded cheeks, her heavy-set frame, her coarse hair. Now she looked at herself a little differently, recognizing and being turned on by her own beauty, her body's sheer readiness to reproduce. She could feel it, that potential, whenever she touched herself. But it still shocked her that Mike, her own brother, could see her that way, even after everything. Jenna took it as a compliment of the highest order.
Over the past few days, she'd had Mike's body close to hers, inside hers, even though she had thought it was someone else's. Now she couldn't help it, she longed for that again. She didn't know yet, what this weekend was going to do to their sibling relationship, but the weekend also wasn't quite over just yet. She knew she still wasn't thinking straight, after the deception that had been pulled on them both. But knowing that didn't straighten out her thoughts.
Jenna leaned over towards Mike, sliding her hand and his from her lap over to his, where an erection was sprouting.
"Maybe we should make that the second stop," Jenna said quietly, scarcely daring to give voice to her thoughts, to her desires.
Mike looked at her, his eyes reflecting her passion. He turned off the road at the next place they could, a long dirt driveway that was overgrown, probably deserted. It went back into the trees far enough for them to park out of sight from the road.
Jenna was shaking with anticipation, still somewhat afraid of what they were about to do. Being tricked into fucking each other was one thing. Choosing to do it, knowing what they were doing and with whom, that was different. There would be no one else, nothing else, to blame this time. This mistake was all on them.
Mike seemed equally hesitant, even though he'd been the one to raise the idea.
"How does this work again?" he asked nervously.
"Normally, two people start by kissing," Jenna said.
"Well this isn't that..." he replied.
They leaned towards each other, a little bit at a time, but somehow there was still space between them, a few inches between his face and hers, some last vestige of the implicit rules they were about to break, that they had already unknowingly broken. Finally Jenna reached over and pulled him by the shoulder, bringing his lips to hers. It was awkward at first, but she couldn't stop. She felt like she could hardly breathe. Inhaling hard through her nose, she opened her mouth to him, to her little brother, still in disbelief at what she was doing.
His hands on her felt familiar, natural, comfortable, and yet she felt herself lighting up at his touch, her skin sensitive, and he ran his hands up under her shirt, eager to explore all of her. She couldn't help but moan into his kiss.
Undressing in the confines of the car was cumbersome. In the back of Jenna's mind, she remembered how just a few days ago she would have balked at the idea of seeing Mike naked. Now his naked body didn't shock her; she'd seen it often enough, even if she'd thought at the time that it wasn't really him. Jenna still felt a little self-conscious about exposing the pudge of her belly and the thickness of her thighs, like she would with anyone. But the way Mike marveled at these parts of her, the way his hands sought out her flesh, holding her tight, her insecurities started to melt away in his embrace.
She ran a hand up and down the length of his erection. So this was what had been inside her several times over the weekend? This was what had driven her to precipitous peaks? This was the penis that she had felt fill her with sperm, after she brought it to orgasm with just her vaginal muscles, and then brought back to hardness the same way? A bit of precum pooled at the top, and she couldn't resist leaning over and having a taste, taking first the head and then the shaft into her mouth. Meanwhile, Mike's free hand went from fondling her full, sensitive breasts, to slipping into her soaking wet slit. She pushed back against him when he touched her clit, and then nearly came when his fingertip probed just inside her.
But Jenna needed more. She knew they both did. She sat up and guided Mike across to her side of the car, reclining her seat as far as it would go. Unfortunately, the car didn't really have enough of a back seat to work with. So awkwardly, Mike got between her legs, half-kneeling on the floor of the car, and pressed himself into her. Jenna slid down in her seat and spread her legs as wide as they would go in that confined space, to give him as much access to her body as she could.
As Mike's cock slid into her, Jenna spared a thought for the possibility that maybe seven times hadn't been enough to knock her up. Maybe this would be the one. No matter, they would stop at a pharmacy on the way back, and no one would be the wiser, except Mike. As he started to thrust slowly, gently, in and out, she squeezed her muscles around him, and he gasped at the unexpected pleasure. His free hand continued to roam her skin, while the other propped him up, half-leaning on the car door, his lips kissing her neck down to her nipples. Jenna felt like there was still something missing, a place somewhere deeper inside of her that she needed to feel him.
It took some rearranging but eventually she got Mike sitting, reclined in the passenger seat, and managed to straddle his waist, taking his penis back into her. In this position, she could take him all the way into her, feeling him press against her deepest recesses where she needed him most. Where she knew she would soon need to feel that splash of warm seed inside her. In this position he could grab her full, round buttocks and clutch her wide hips down against him as he thrust up into her. She could tell he wasn't going to last much longer, but neither was she. Jenna could feel her orgasm building, and knew that when it hit, she was going to lose what little control over herself she had left.
Pressing her public mound hard against him, Jenna leaned down and took his face in her hands, and kissed him hard. She felt him swell up inside of her, the warning sign of what was about to come, and just feeling that was enough set her off. She was screaming now, though she couldn't do anything about it, as her muscles clenched and unclenched, spasms roiling through her abdomen. The first splash of his cum hit the back of her pussy and fanned out within her, and she felt her vaginal muscles clamp down on him and milk him for all he was worth, her reproductive system in overdrive, even if this was exactly the wrong man to reproduce with. His ejaculate kept coming, in wave after wave, triggering new peaks of her own orgasm. She was light-headed and running out of breath, and she began to shudder and shake on his lap, still impaled on his cock.
