Charlotte had masturbated before, of course. On the advice of one of her friends, Connie, she had even broken her own hymen with the handle of her toothbrush. But she’d never done anything more sexual than kissing in public. In fact, she prided herself on her virginity. Thus her anger at James touching her.

Then again, she’d never been this horny before.

Her mind stayed focused on Brian’s rubbing noises and she started to wonder if she was imagining things. Surely he couldn’t be wanking off for so long, right? Supposedly boys came in seconds; at least, that what she’d always heard. And why would he jack off on the bus, in a place where if he DID cum, it would just get all in his underwear?

Charlotte’s doubts ceased when she started to hear Brian’s breathing speed up. This caused the speed of her own breathing—and hand—to speed up as well. Figuring that there was no way she’d be able to stop now, she raised her hips off of the seat and buried her middle finger inside of her wet pussy, beginning to rub her clit with her thumb instead.

Thoughts of boys started going through her head, images of men she’d seen online, mixed with her brother Tim, standing in front of the mirror, staring at her, his penis in his hand. Her dream flashed in front of her eyes and she remembered how good her brother’s penis had felt. Except it hadn’t BEEN her brother’s penis. It had been Brian’s. And it was only an arm’s length away.

Charlotte wasn’t stupid. She knew that part of the reason she was wanting Brian so bad was because of her breakup with James. She also knew that she was REALLY bad with rebounds; she had a burning desire to be desired by a boy. To be fully truthful with herself, she’d always known that she’d eventually date Brian, and had once even been convinced that he was the boy she was going to marry. Her idea was that she’d play around with the “bad boys” for a while and then settle down with someone who worshiped her. Someone like Brian.

Add all of this to James groping her and her accidentally groping Brian, not to mention that dream with her brother, and she was hot and ready.

It took her only moments for a plan to form in her horny mind and only a second after that to put the plan into action.

Pretending to be asleep, Charlotte let her right hand drop off the seat….

… and she froze in confusion. Yes, Brian’s penis was still wonderfully hard as a rock, but his hand was obviously nowhere near the member. But the rhythmic thumping was still going on, as was the fast breathing. In a flash of realization, Charlotte knew that it was AMBER masturbating, not Brian.

Still, she was hornier than she’d ever been before. And her hand was now on a boy’s dick for only the second time. Instead of pulling back, she grabbed hold the best she could and continued to rub herself.

Only a couple of seconds later, Charlotte felt Brian’s hand on her shoulder, trying to rouse her from sleep. His touch served only to turn her on more.

“Charlotte?” his dry, tentative voice came, and she debated on whether or not to pretend to still be asleep. He wasn’t moving her hand off of his penis, after all.

“I’m awake, Brian,” Charlotte said, her voice thick with lust.

A few seconds of stunned silence followed, punctuated only by a moan and more rubbing sounds coming from the seat ahead of them.

“Oh!” Brian’s voice was so shocked that Charlotte would have laughed if she’d been capable.

“Kiss me. Please?” Charlotte said, before the words had even formed in her mind. She positioned herself so her head hung over the bench, mussed ponytail hanging down her face and brushing on Brian’s cheek. His eyes were wide open as he stared up at her.

“Are… are you sure?”

As an answer, Charlotte removed her fingers from her crotch and slid off of the bench, her right hand still on Brian’s bluge. He let out an audible “Umph!” as she landed on him. Not letting herself think, she removed herself from Brian’s penis and put her hands in his hair, inadvertently wiping the juices from her pussy into it.

Brian groaned as she started to dry hump him. Charlotte bent down and began to kiss him, tenderly at first, and then more passionately as he started to kiss back. She moaned each time that her pussy met his penis, a few layers of cloth the only thing stopping them from full coitus.

Realizing she wanted more, and realizing that Brian wouldn’t do anything more without her starting it, Charlotte took the boy’s hands and placed them on her breasts as she rode him. He got the idea quickly and started to squeeze her flesh over her shirt and bra. She bent down and started to kiss him again, this time shoving her tongue into his mouth.

With that, Brian seemed to finally lose control and began to take action of his own accord. His hands traveled down her body to her waist, going beneath her shirt. Charlotte gasped as he traveled back up her torso and slipped beneath her bra, cupping the skin of her breasts. His fingers tweaked her nipples and she gasped again.

“Brian, I need you right NOW,” Charlotte said in a voice that was probably far too loud. She pulled away and looked down at him. He nodded.

As if their thoughts were one, they both bounded up and sat on the seat. Brian pulled down his pants and underwear at the same time, letting them rest at his ankles. Charlotte stared at the outline of his penis in the light of Shelly’s lamp as she pulled her shorts and panties down to her ankles as well, pulling her foot out of one side. Thinking of the origin of their light, Charlotte looked over to Shelly, who was unabashedly watching the scene, chin resting on the seat back, eyes wide. Jodee was also sitting up, but, unlike her sister, her eyes were currently directed toward Amber instead of Brian’s penis. Charlotte couldn’t see the girl in the seat in front of them from her vantage point, but the sounds of moaning and squishing were quite audible. There was also a very telling, musty scent in the air.

Charlotte put her finger to her lips as she raised her bottom off the seat and positioned herself over Brian, her butt towards him. Shelly only nodded, and Jodee did as well, scooting forward so she would have a better view.

Suddenly, there was a pressure against her pussy and Brian’s hands were on her shoulders, pressing her down. Very grateful that she hadn’t a cherry left, Charlotte squealed in delight as her virginity was taken away from her. Now raised off the seat, she looked down at Amber who looked back up at her.

“Are you two…?” Amber mouthed the words.

Charlotte, not needing anything further, nodded as Brian started to thrust up into her.

Amber sat up, scooting her sweat pants down to reveal that she had nothing underneath. Her slightly hairy pussy gleamed in Shelly’s lamp.

As Amber began furiously masturbating, Charlotte finally started to help Brian, bouncing up and down on his stiff penis. The motion of the bus aided them, every bump in the road making her give out a little moan.

“Jodee,” Charlotte heard Shelly say, “Your head’s in the way. I can’t see.”

Charlotte looked over at the girl who had spoken, only to feel Brian’s hand reaching up under her shirt again. There was something intoxicating about facing away from him as he screwed her, knowing that he was looking at her butt as she bounced. Jodee suddenly stood up and sat on the seat next to them, giving her sister the full view that she wanted. The older girl was obviously also getting an eyeful.

Gasping as a particularly violent bump thrust Brian’s penis deep into her, Charlotte looked back to Amber, who was looking up at her, two fingers stuck up her vagina, pumping furiously. Brian’s hands found Charlotte’s breasts, grasping them tightly. Her bra was still pushed upward on her chest from the last time he’d found her mounds. She closed her eyes, breathing in the musty smell that now permeated the area.

Swallowing, she realized that she was about to cum. Brian’s thumbs were making little swirls on her nipples. Charlotte rested her chin on the seat in front of her, eyes closed. Knowing that the sooner she came, the sooner this would all be over, she held her orgasm off the best she could.

“Shelly, turn off your light!” Jodee’s voice came from behind Charlotte, startling her. Opening her eyes, Charlotte craned her neck over to Jodee and saw the girl looking down the aisle of the bus, eyes wide. Charlotte followed her gaze and saw that the bus driver, a middle-aged woman with long blonde hair, was staring back at them in the mirror.

Of course, they couldn’t have stopped then if they wanted to, and Charlotte could only hope that the distance was great enough that the driver couldn’t really tell what was going on.

The light went off as Shelly obeyed her sister’s order. Closing her eyes again, Charlotte lost herself to the rhythm of Brian’s love, resting her chin on the seat in front of her once again.

Suddenly, a pair of soft, sweet lips were pressed against hers and Charlotte knew that Amber was kissing her. Instead of being repulsed, as she thought would happen, Charlotte found the kiss pushing her over the edge.

She began to cum.

She gasped, allowing Amber’s tongue to go inside of her mouth, and her pussy lips started to spasm. It was a far greater experience than any masturbation had every provided her and she even wondered if she’d ever really had an orgasm before this moment. Her vagina walls continued to compress, embracing Brian’s penis over and over again. She had stopped breathing.

Amber’s own breath halted and the lips on Charlotte’s mouth froze.

As the girls’ breaths sucked back into their bodies and Amber’s lips tore free of hers with a “pop,” Charlotte felt her breasts getting squeezed. Brian’s pumping penis had accelerated to a crazy speed.

She was having sex with a boy.

The thought was so shocking that she almost pulled away and might have done if she weren’t in an amazing afterglow.

“Sorry,” Charlotte heard Amber say breathlessly in the darkness, “Sorry, it’s just that my sisters and I always kiss when we do this.”

Charlotte would have said it was okay, but her mind was preoccupied. As the afterglow began to fade, she thought of telling Brian to pull out before he came inside of her.
