Kylie tried not to watch them, she really did. She had tried to read her book, but it had been impossible to concentrate on the words on the page when the only thing she could think about was the couple across the aisle from her. They'd gotten on the bus about an hour after she had, walking down the aisle holding hands and laughing. It had only been a few minutes after the bus had gotten back on its way when they'd begun kissing. It'd been easier to ignore them then. At first, Kylie had just looked out the window and watched the scenery go by, thinking about the boyfriends she'd had in high school, wondering when she'd finally lose her virginity.
At the first stop, the couple had stayed on the bus, completely ignoring all the other passengers getting off for soda or bathroom breaks. Kylie had gotten off the bus with everyone else, not for the bathroom or a snack, but to give herself a chance to cool down. While she'd been able to mostly ignore them, she was more than a little turned on after listening to their breathless moans and whispers for the past hundred miles.
It had gotten worse after the stop. By then, Kylie had tossed her book aside and tried to tune out their sounds with her ipod, but she found her eyes continually drawn back. Until finally, Kylie stopped trying to look away. Instead, she adjusted herself so she leaned against the side of the bus and faced them, her legs stretched out on her seat in front of her. She figured if they happened to see her watching, she could quickly look away, or pretend to be falling asleep. But considering their total absorption in each other, she didn't think she had anything to worry about.
Though the lighting in the bus was growing dim, Kylie could see that the man had unbuttoned the woman's shirt, exposing her breasts almost completely. The woman wore no bra and her nipples were hard, and seemed, to Kylie's inexperienced eye, almost painfully erect. The man pinched and pulled her nipples, alternating between them. The woman occasionally arched her back and thrust her chest out toward the man, and Kylie assumed she must have been enjoying the sensation. Kylie had never seen anyone touch a woman's breasts the way the man was, and had certainly never experienced it. Her boyfriends, the few who had been allowed to touch her breasts in high school, had mostly rubbed and squeezed them like they would a cow. She'd never enjoyed it much, but not knowing better, she'd thought that was the way foreplay was supposed to be. Which might explain why she'd not actually gone all the way with any of them.
While he continued to pinch the woman's nipples, the man kissed the woman. As Kylie watched, the man kissed along the woman's jaw and over toward her ear and then down her neck. The woman arched her back again and moaned. Almost without knowing it, Kylie began to lightly tease her own nipples through her shirt. When she realized what she was doing, she looked around at the other passengers, making sure no one had seen her touching herself. Certain of her privacy, Kylie continued to tease her nipples and then, experimentally, pinched one. She gasped at the sensation, understanding what the woman was feeling. Kylie watched as the man lowered his head to one nipple and suckled it. Kylie did know what that felt like, and she had enjoyed it, a little. But this man seemed to do something different than her boyfriends had; occasionally, he would almost bite down on the woman's nipple and each time the woman would grab his head. At first, Kylie thought the woman wanted him to stop. Then she realized that she was grabbing his head to hold him hard against her breast.
